Dietary oils play a crucial role in maintaining a healthy diet. However, with the increasing number of oils available, it became a challenging task for food producers and consumers to select the best oil for their needs. In this work, an easy-to-understand nutrition quality score was created, using a model that included beneficial lipid compounds criteria according to the dietary recommendations published by international food and health organizations. The algorithm assigned points for each component of the model considering their content in each particular oil. The points were added up and the fats and oils were classified by the corresponding percentile. As a result, among the 32 edible oils that were evaluated, virgin olive oil ranked first with a score of 100. All plant oils, except for margarine and coconut oil, ranked above the 50th percentile. Receiver–operator curves and regression models showed that saturated fatty acids may be able to predict the score, and thus, the nutritional quality of the oils. In conclusion, the proposed nutritional quality score would promote healthy and nutritious food options for consumers and would provide food producers with a valuable tool to select high-quality oils for their products, ensuring that they meet the nutritional requirements.

Due to a growing challenge to feed the world’s population and an increased awareness to minimize the impact of our food choices on climate change, a more plant-based diet has gained popularity with a growing number of plant-based products on the market. To stimulate a plant-based diet that also improves long-term health, data are needed to monitor whether these products are healthy alternatives to animal-based foods. Therefore, this study inventoried 916 plant-based meat, fish, and dairy alternatives from eight Dutch supermarkets. The nutritional quality of each product was assessed by (1) the Dutch food-based dietary guidelines and (2) the Nutri-Score. The results show that over 70% of meat, fish, and dairy alternatives have an A/B Nutri-Score (indicating high nutritional quality), but do not comply with the Dutch dietary guidelines. This is mainly due to high salt and low vitamin B12 and iron content (meat and fish alternatives) or low protein and calcium levels (dairy alternatives). In conclusion, the majority of plant-based products are nutritionally not full alternatives of the animal-based equivalents; however, there are still opportunities for reformulation. To aid the consumer in making healthy plant-based food choices, a better alignment between the Nutri-Score and the recommended dietary guidelines is needed.

The 2010 Healthy, Hunger-Free Kids Act (HHFKA) improved the nutritional quality of food served in schools. This longitudinal study examined school food offerings over time from school year 2010-11 to 2017-18 in public schools (n = 148) in four New Jersey cities. Six food indices were used to assess the number of healthy and unhealthy items offered as part of the National School Lunch Program (NSLP), in vending machines, and à la carte (i.e., competitive foods). Multilevel, multivariable linear regression with quadratic terms was used to model the trends over time. Interaction terms were added to examine whether the time trends varied by school-level factors, such as proportion of students eligible for free or reduced-price meals (FRPMs), race/ethnicity of enrolled students, and school level. Over the study period, healthy items offered in the NSLP increased (p < 0.001), while unhealthy items in the NSLP decreased (p < 0.001). Significantly different rates of declines in NSLP unhealthy offering were observed among schools at the two extremes of FRPM eligibility (p < 0.05). The trends for healthy and unhealthy foods offered in competitive foods showed significant non-linear trends, and differences were observed for school-level race/ethnicity, with worse outcomes for schools with majority Black student enrollment.

Hairless canary seed (Phalaris canariensis L.) is a novel true cereal that is now approved for human consumption in Canada and the United States. This true cereal grain has higher protein content (22%) than oat (13%) and wheat (16%) and represents a valuable source of plant proteins. Assessment of canary seed protein quality is therefore essential to evaluate its digestibility and ability to provide sufficient amounts of essential amino acids for human requirements. In this study, the protein nutritional quality of four hairless canary seed varieties (two brown and two yellow) were evaluated in comparison to oat and wheat. The assessment of anti-nutrients contents (phytate, trypsin inhibitor activity, and polyphenols) showed that brown canary seed varieties had the highest content in phytate and oat the highest in polyphenols. Trypsin inhibitor level was comparable among studied cereals, but slightly higher in the brown canary seed Calvi variety. In regard to protein quality, canary seed had a well-balanced amino acid profile and was particularly high in tryptophan, an essential amino acid normally lacking in cereals. The in vitro protein digestibility of canary seeds as determined by both the pH-drop and INFOGEST (international network of excellence on the fate of food in the gastrointestinal tract) protocols appears slightly lower than wheat and higher than oat. The yellow canary seed varieties showed better overall digestibility than the brown ones. For all studied cereal flours, the limiting amino acid was lysine. The calculated in vitro PDCAAS (protein digestibility corrected amino acid score) and DIAAS (digestible indispensable amino acid score) were higher for the yellow C05041 cultivar than the brown Bastia, similar to those of wheat, but lower than those of oat proteins. This study demonstrates the feasibility and utility of in vitro human digestion models for the assessment of protein quality for comparison purpose.

21 Páginas.-- 4 Tablas.-- 4 Figuras, Vegetarian foods are plant-based (PB) foods, often perceived as healthier foods than animal-based (AB) foods. The objective of this study was to analyze the nutritional quality of a set of PB foods (meat, milk and dairy products) marketed in Spain, and to compare their nutrient profiles with respect to some AB counterparts. Nutritional information per 100 g or mL, ingredients, and nutritional declarations, as well as the Nutri-Score, NOVA, and Eco-Score of each food were collected from Open Food Facts. Differences in the nutrient compositions between PB foods and their counterparts, and between the different groups of PB foods, were assessed at a 5% significance level. A total of 544 PB foods and 373 AB foods were identified. Overall, PB foods had a higher median content of fiber and carbohydrates, but a lower amount of proteins (except PB "meat" analogues: 14 g) and saturated fats (except PB "cheese alternatives": 12.5 g), than the AB counterparts (p < 0.05). PB "milk alternatives", particularly oat "milk", showed a higher median content of total carbohydrates (8 g) and sugars (5.5 g) compared to cow milks (4.7 g carbohydrates/sugars, on average; p < 0.001). PB "meat alternatives" also had a significantly higher value of carbohydrates (9 g) than AB meats (2 g, on average; p < 0.001). PB foods were mostly classified as Nutri-Score A and B (86%). However, more than half of them were of NOVA groups 3 and 4. Thus, there is a great diversity of PB meat and milk/dairy product alternatives on the Spanish market. Despite being products of good nutritional quality compared to AB foods, they also carry drawbacks that could have an impact on nutritional health., This research received funding from CIBERESP (Spanish Network of Epidemiology and Public Health); Proyecto Intramural 2023.

Although the black soldier fly frass fertiliser (BSFFF) is globally recognised as a promising and potential high-quality organic fertiliser, there is inadequate information on its impact on the growth performance and nutritional status of maize. Furthermore, no information exist on their combination with mineral fertiliser (NPK) as well as economic impact on maize production. This study evaluated the comparative impact of BSFFF, NPK and commercial organic fertiliser (Evergrow®) on growth, nitrogen use efficiency, yield, nutritional quality, and profitability of maize under greenhouse conditions. The treatments included: (1) sole application of BSFFF, conventional compost of brewers’ spent grain (BSG), Evergrow, and NPK at rates equivalent to 100 kg nitrogen (N) per hectare; (2) BSFFF and BSG combined with NPK so that each fertiliser supplies 50% of the N required; and (3) the control (unamended soil). Our findings revealed that BSFFF increased maize grain yield at higher rates: 2-25, 25-113 and 153-212% than NPK, BSG and Evergrow, respectively. Similarly, the BSF frass application led to higher maize growth and yield than the control treatment. The agronomic N use efficiency of maize grown using BSFFF was 2 and 3 times higher compared to that of BSG and Evergrow, respectively. Maize grown using BSFFF and NPK had higher crude protein and crude fibre content compared to the other treatments. The net income generated from the commercialisation of maize grown using a combination of BSFFF and NPK was 2, 163 and 173% higher than those achieved using sole NPK, mixture of BSG and NPK, and sole BSFFF, respectively. Our results imply that developing and promoting BSFFF alone or in integration with NPK can enhance the food security and livelihoods of smallholders, while safeguarding planetary health.

This study evaluates the nutritional quality and in vivo biological activity of a peach palm by-product food ingredient processed via solid-state fermentation by shiitake culinary-medicinal mushroom, Lentinula edodes. The group of Wistar rats that consumed this diet had higher total dietary fiber content, digestibility, rate of protein quality, and protein efficiency. They also presented a late and softer insulinemic peak with an increase in the glycemic index, demonstrating amino acid limitation but with a feasible matrix as a complement protein. Discrete variation on total cholesterol and triglycerides was observed with a reduction in lipid profile, attributed to its high dietary fiber content. Lipids from within the liver and stool revealed that the fermented diet contained the lowest rates of fat in the liver and, consequently, the highest elimination compared to the other control diets. The serum lipid profile suggests a positive modulation of this diet, and that it has good nutritional quality with the potential to positively influence glycemic and lipid profiles.

Storage conditions influence the nutritive value and quality of many legumes. The aim of this study was to evaluate the quality of beans stored under hermetic conditions as a strategy for preserving the quality of beans post-harvest. Three bean varieties [Rosecoco, small red (Wairimu)], and red mottled (Nyayo)] were adjusted to three moisture levels (12%, 15% and 18%) and stored in hermetic bags and ordinary polypropylene bags and sampled after 0, 45, 90, 135,180, 225 and 270 days for chemical and anti-nutritional analysis. Total soluble sugars, in-vitro starch and protein digestibility, free amino nitrogen, tannin content and phytic acid content of the beans were determined using standard methods. Results showed that the beans in hermetic bags had 22%, 23% and 18% higher total soluble sugars, in-vitro starch and protein digestibility, respectively, than those in polypropylene bag during storage. On day 225 of storage, beans in hermetic bags had the optimal in-vitro starch and protein digestibility, and tannin content. Principal component analysis indicated that nutrient and anti-nutrient retention of the beans was achieved with lower storage moisture and duration in hermetic bags. The results of this study can be used to explain the superiority of the hermetic storage technology over ordinary methods of beans storage, and by extension other legumes, in nutrient retention during storage.

The present study aimed to investigate the effect of different microwave pre-drying times under hot-air-drying processes on the quality properties and sensory evaluation of Sipunculus nudus (S. nudus). The colour, proximate analysis, amino acid content, fat oxidation, and volatile components of dried S. nudus were determined. Microwave pre-drying could significantly (p < 0.05) increase the drying rate and shorten the drying time. The results of colour, proximate analysis, and amino acid content indicated that microwave pre-drying could improve the quality of the product, resulting in dried S. nudus with less of a loss in nutrients. The samples that underwent microwave pre-drying had a high degree of fatty acid oxidation and low monounsaturated fatty acid content, which facilitated the formation of volatile components. Additionally, the MAD-2 and MAD-3 groups had high relative contents of aldehydes and hydrocarbons, and the FD group had the highest relative content of esters found in the samples. The relative content of ketones and alcohols did not differ significantly between the different drying groups. The finding of this study has important potential for enhancing the quality and aroma of dry S. nudus products with microwave pre-drying during the drying process.

Sodium chloride (NaCl), as a eustressor, can trigger relevant pathways to cause plants to produce a series of metabolites, thus improving the quality of crops to a certain extent. However, there are few reports on the improvement of nutrient quality and flavor of hydroponic Chinese chives (Allium tuberosum Rottler) by sodium chloride. In this study, five NaCl concentrations were used to investigate the dose-dependent effects on growth, nutritional quality and flavor in Chinese chives. The results show that 10 mM NaCl had no significant effect on the growth of Chinese chives, but significantly decreased the nitrate content by 40% compared with 0 mM NaCl treatment, and the content of soluble protein and vitamin C was increased by 3.6% and 2.1%, respectively. In addition, a total of 75 volatile compounds were identified among five treatments using headspace solid-phase microextraction gas chromatography/mass spectrometry (HS-SPME/GC-MS). Compared with the 0 mM NaCl treatment, 10 mM NaCl had the greatest effect on the quantity and content of volatile compounds, with the total content increased by 27.8%. Furthermore, according to the odor activity values (OAVs) and odor description, there were 14 major aroma-active compounds (OAVs > 1) in Chinese chives. The “garlic and onion” odor was the strongest among the eight categories of aromas, and its highest value was observed in the 10 mM NaCl treatment (OAVs = 794).Taken together, adding 10 mM NaCl to the nutrient solution could improve the nutritional quality and flavor of Chinese chives without affecting their normal growth.

With the increasing consumer awareness and demand for healthy food and natural ingredients; there is an urgent need to develop and propose innovative products to industry. In this study, the combined effect of various time of pre-incubation (30, 60 and 90 min) in vinegar and the addition of fucoxanthin (Fux) extracted from the brown alga Dictyopteris polypodiodes to the covering oil of sardine fillets was investigated during 3 months of refrigerated storage at 4◦C. Compared to fresh sardines, biogenic amines (Bas) decreased significantly in all marinated lots (histamine

In order to study the physicochemical and nutritional characteristics of kiwifruit varieties, 14 kiwifruits from different species with different flesh colors were selected for research. The pectin content was significantly higher in green-fleshed kiwifruits than those in red-fleshed and yellow-fleshed kiwifruits. Red-fleshed kiwifruits had the highest total flavonoid content, and green-fleshed kiwifruits in A. eriantha had the highest chlorophyll a content, chlorophyll b content and total carotenoid content. The energy and carbohydrate contents of yellow-fleshed kiwifruits were significantly lower than those of red-fleshed kiwifruit. Moreover, the protein contents in A. chinensis and A. chinensis var. deliciosa were higher than those in other species. The content of vitamin C in A. eriantha was far higher than in other kiwifruits. Red-fleshed kiwifruits had a significantly higher vitamin E and vitamin B1 content than green-fleshed kiwifruits. In addition, 1-pentanol, trans-2-hexen-1-ol, n-hexane and styrene presented only in red-fleshed kiwifruits. Therefore, these could be used as a characteristic fragrance for red-fleshed kiwifruits. Moreover, the varieties were ranked comprehensively by principal component analysis (PCA), among which the top four highest-ranking kiwifruits among the 14 varieties were ‘Huate’, ‘MHYX’, ‘Jinkui’ and ‘Xuxiang’, respectively. This study provides a reference for consumers and markets on quality improvement and processing.

Enzymatic browning is a major problem in minimally processed banana puree; it reduces consumer's acceptability and affects nutritional quality. The objective of this work was to evaluate the effects ultrasound (40 kHz/10 min), microwave (800 W/ 25 s) and UV-C radiation (1.97 kJ/m2) applied to banana puree. Colour parameters (L*, a*, b*, chroma and hue), browning index (BI), polyphenol oxidase (PPO) and peroxidase (POD) activities, total phenolic compounds (TPC), antioxidant capacity (AOC) and microbiological counts were monitored throughout storage at 4 °C. Ultrasound (US) and microwave (MW) treatments achieved a significant (p < 0.05) reduction in PPO activity and BI; moreover, ultrasound effectively retained phenolic compounds content (75% of initial value). The AOC was in coincidence with TPC values. POD activity was partially inhibited by UV-C while MW and US increase its activity. Although UV-C treatment was not effective to control browning development, it was effective to maintain microbiological stability after 20 days of storage (1.48 ± 0.01 log CFU/g). The evaluated treatments have the advantage of being less aggressive than conventional thermal treatments while maintaining fresh characteristics of the product.

Las sopas son uno de los alimentos más importantes para los mexicanos. Sin embargo, por su alto contenido de carbohidratos, poca fibra y proteína, se caracterizan por estar desbalanceadas nutrimentalmente. El hongo Pleurotus incrementa la calidad nutricional de los alimentos (sopa de vegetales, snacks y pan de caja, por ejemplo). Las pastas son de bajo valor biológico por carecer de lisina; en cambio, Pleurotus columbinus posee aminoácidos esenciales, por lo que, al elaborar una pasta en combinación con este hongo, se obtendría una mayor calidad nutricional. Este trabajo muestra que la proteína de las pastas se incrementó en porcentajes de 32.15 % hasta 79.27 %, no hubo cambio en las propiedades físicas (tiempo de cocimiento y absorción de agua), a excepción de la desintegración, que se incrementó de 6.4 % hasta 8.5 %. La harina del hongo incrementa la cantidad proteínica de la pasta, lo cual ayudaría a mejorar la alimentación de la población.

Background Environmental conditions affect the quality of the fruits and their organoleptic properties. In low-tech greenhouses, these environmental conditions are frequently not optimal for crops. Therefore, the present study demonstrates the effects of the use of an integrated passive heating and cooling system in a greenhouse located in the Mediterranean area on the quality of pepper fruits. Results The results indicate that the passive system utilized (i) improved many parameters, such as average weight of fruits, °Brix, glucose and fructose content, and P and K content; (ii) increased the values of b* and hab *; and (iii) reduced total phenolic compounds, total amino acids content, and Fe and Zn content. However, the degree of the effect of the climatic factors on these parameters was also affected by harvest time. Conclusion This novel study highlights the possibility of improving the nutritional quality of pepper fruits by modifying the environmental conditions through the use of passive heating and cooling systems at the same time as reducing the carbon footprint. © 2021 Society of Chemical Industry.

Background The increasing evidences on the relation between diet and human health are driving the consumers toward the choice of foods with high amount of nutrients, considered the molecules responsible for the regulation of several metabolic and biochemical processes, and for the prevention of many chronic diseases. Among food products, fruits represent a natural source of many different nutrients and possess much importance in a balanced diet. The increase of the micro/macronutrient levels and the decrease of antinutrients amount are considered main objectives for the improvement of fruit trees nutritional value. Scope and approach This review summarizes many of the attempts made to increase the nutritional quality of fruit tree species during the last decades through the application of traditional and molecular breeding technologies, and the most recent New breeding techniques (NBTs). Key findings and conclusions New genotypes with improved nutritional quality have been obtained for different fruit tree species, either by increasing the content of well-known beneficial molecules, such as phenolic compounds, vitamins, and carotenoids, or by decreasing the levels of specific antinutrients. The development of molecular techniques and biotechnological tools allowed the identification and validation of candidate genes involved in the regulation of specific classes of nutritional compounds in fruit trees, and useful to obtain nutritionally improved products. NBTs represent alternative tools to classical breeding techniques, to regulate one or more fruit trees key nutrients in a more quick and precise manner. However, genetic engineering approaches still present public and regulatory concerns that strongly limit their exploitation.

Sourdoughs based on fermentation by lactobacilli have the potential to produce gluten-free maize-based bread with acceptable technological and rheological characteristics, nutritional quality and a more prolonged shelf life. Of the 17 treatments compared (with or without sourdough, and involving single and multiple LAB species), treatments 12C (Lactobacillus brevis, L. sanfranciscensis + L. plantarum) and 8C (L. brevis + L. paralimentarius) showed the lowest rate of complex modulus, while treatments 11C (L. sanfranciscensis + L. brevis + L. paralimentarius) and 2C (L. brevis) led to the greatest reduction in baking loss. The crumb moisture content of all of the formulations decreased with storage. Breads produced with treatment 2C (L. brevis) had the highest crumb moisture content when freshly baked; while loaves produced with treatment 3C (L. paralimentarius) had the highest crumb moisture content after four days of storage. A sensory evaluation indicated that sourdough-based maize breads were superior to both control and chemically acidified breads. The optimal treatments were to use sourdough seeded with treatment 2C (L. brevis), with treatment 4C (L. plantarum), with treatment 8C (L. brevis + L. paralimentarius) or with treatment 11C (L. sanfranciscensis + L. brevis + L. paralimentarius).Significance StatementOf the 17 treatments compared, treatments 12C and 8C showed the lowest rate of complex modulus, while treatments 11C and 2C led to the greatest reduction in baking loss. The optimal treatments were to use sourdough seeded with treatment 2C, with treatment 4C, with treatment 8C or with treatment 11C.

Deep frying is the process of immersing food in hot oil at a temperature of approximately 180°C. During deep frying, different chemical reactions are taking place, resulting in changes in the physicochemical properties of the frying oil, eventually leading to harmful health effects on the consumers. Nevertheless, based on economic feasibility, both the domestic and industrial levels tend to repeatedly use edible oils for deep frying. Thus, the current study aimed to evaluate physicochemical and nutritional parameters of commercially available coconut oil, palm oil and sunflower oil and to investigate the effect of repeated deep frying for the physicochemical and nutritional parameters of the studied oil samples. Thereby, the optimum number of frying cycles for each type of oil was also investigated. In order to achieve that, using coconut, palm and sunflower oils, potato and fish were fried separately for five repeated frying cycles. As per the results, regardless of the frying material, the relative density, colour, peroxide value, free fatty acid value of coconut oil, palm oil, and sunflower oil were increased significantly with increase the number of frying cycles whereas the smoke point and moisture content was found to be significantly decreased. In contrast, the number of cycles suitable for repeated frying is varying upon the frying material. Accordingly, coconut oil has proven to be used for three frying cycles of potato and five frying cycles of fish: palm oil for one frying of potato and two fryings of fish without adversely altering their physicochemical and nutritional properties. Conferring to the obtained results, the use of unsaturated oil like sunflower oil on repeated frying is not recommended.

PurposeThe study aimed to analyse the nutritional quality of self-proposed or prescribed weight-loss diets shared by female Korean adolescents through a social media platform and identified potential dietary problems.Design/methodology/approachA total of 317 weight-loss diets, shared by 107 female adolescents between the ages of 12 and 18 in April 2019, were collected from three Kakao Open Chat rooms of which the main topic was “weight-loss diet”. The weight-loss diets were converted to daily energy and nutrient intake.FindingsApproximately two-thirds of the subjects were normal or underweight, and more than half of them were limiting energy intake to less than half of the recommended daily amounts. The average daily intake of energy and most nutrients did not meet the standard intake levels. Approximately 20% of the subjects were breakfast skippers, while 8 and 5% were dinner and lunch skippers, respectively. Notably, meal skippers tended to fast longer and have an uneven distribution of daily energy intake per meal. The percentages of energy contribution from macronutrients, particularly carbohydrates, also deviated more from the acceptable range in the meal skippers. The weight-loss diets of the subjects with particularly low daily energy intake were categorised into simplified, unbalanced and nutrient-poor, energy-dense meals. Overall, the nutritional quality of the self-proposed or prescribed weight-loss diets was poor. More effective and proactive educational interventions in school environments should be developed to promote positive eating behaviours in adolescents and free them from their obsession with body image.Originality/valueTo the best of the authors’ knowledge, this study is the first attempt to analyse the nutritional quality of female adolescents' self-proposed or prescribed weight-loss diets.

Trans (t) fatty acids (TFA) from partially hydrogenated vegetable oils (i.e., industrial trans) have been phased out of foods in many countries due to their promotion of cardiovascular disease. This leaves ruminant-derived foods as the main source of TFA. Unlike industrial TFA where catalytic hydrogenation yields a broad distribution of isomers, ruminant TFA are enzymatically derived and can result in enrichment of specific isomers. Comparisons between industrial and ruminant TFA have often exonerated ruminant TFA due to their lack or at times positive effects on health. At extremes, however, ruminant-sourced foods can have either high levels of t10- or t11-18:1, and when considering enriched sources, t10-18:1 has properties similar to industrial TFA, whereas t11-18:1 can be converted to an isomer of conjugated linoleic acid (cis(c)9,t11-conjugated linoleic acid), both of which have potential positive health effects. Increased t10-18:1 in meat-producing ruminants has not been associated with negative effects on live animal production or meat quality. As such, reducing t10-18:1 has not been of immediate concern to ruminant meat producers, as there have been no economic consequences for its enrichment; nevertheless at high levels, it can compromise the nutritional quality of beef and lamb. In anticipation that regulations regarding TFA may focus more on t10-18:1 in beef and lamb, the present review will cover its production, analysis, biological effects, strategies for manipulation, and regulatory policy.

Fish production and fish processing waste have straight connection. In India, the waste produced during the processing of fish is predicted to be approximate 3.6 million metric tonnes, 48 per cent of the total body weight of Indian and exotic major carps is thrown away as waste (non-edible ). The present research, it was conducted to compare the total lipid content (TLC) and fatty acid composition from the liver of captured and cultured fish, Labeo rohita (Hamilton) having weight more than 500 gram during different months as well as to evaluate its nutritional quality. Maximum total lipid content (33.33±0.14%) was found in the liver of cultured fish in May month, while the minimum (15.26±0.24%) was in the liver of captured fish in the month of January. During the study, total lipid content was found to be considerably elevated in cultured than captured Fish, Labeo rohita (Hamilton). The amount of three major groups of fatty acids namely polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids was found to be maximum in captured fish during the month of March 97.19±0.96%, 61.30±0.56% and 95.39±0.31% month of April respectively. Total n-6 polyunsaturated fatty acids were observed to be highest (21.95±8.05%) in the waste of liver in cultured fish during the month of March. Hence, it is concluded that the processing waste (liver) of the captured and cultured, Labeo rohita (Hamilton) is a prosperous resource of the essential fatty acids i.e. PUFAs and total lipids. Further, it is observed that captured species are rich in fatty acid composition as compared to cultured species. Food industries can manufacture by-products from these high nutritional value contents of waste for human utilization. EPA and DHA also reduce the risk of various life threatening diseases.

The study aimed to evaluate the addition of banana blossom (12.5, 25, 37.5, and 50% w/w) on nutritional quality, histamine content, bacterial count, and sensory characteristic in the fish floss prepared from little tuna (Euthynnus affinis). The crude protein content, essential amino acids, lipid, and polyunsaturated fatty acids (PUFA) steadily decreased (p 0.05) the acceptability score for all attributes assessed. Taken together, the tuna floss added with 37.5% of banana blossom may be potentially developed as a low-histamine tuna-based product with high ffibre andEPA+DHA, as well as highly acceptable for consumers.

This study aims to investigate the fermentation of Avocado seed flour using Lactobacillus plantarum. Proximate composition and most important mineral contents of Avocado seed flour after fermenting for 24, 48 and 72 h were compared with dry unfermented Avocado seed flour. Avocado seed flour fermented for 72 h had significant increase (p

The color and nutritional quality of vegetables directly affect the choices of consumers and thus affect the commercial value of the vegetable products. Green light can penetrate the outer leaves and reach the inner leaves to promote photochemical reaction of the overlapping leaves of head vegetables. However, whether this promotion can increase the nutritional components and change the color of the inner leaves of head cabbages, which is one of the major head vegetables largely produced worldwide, remains unclear. Therefore, we investigated the changes in the colors and the concentrations of chlorophyll (Chl) and carotenoid of the inner leaves of two types of cabbages by externally irradiating the cabbage with green light. The results showed that a short-term (48 h) irradiation with low light intensity (50 μmol m−2 s−1) of green light enhanced the Chl concentration and colors of the inner leaves of cabbages, and the positive changes of these indicators increased as the leaf layers approached the head center of the cabbage. Simultaneously, we also establish a method to effectively estimate the Chl concentration using luminosity (L*) and greenness (− a*) when the Chl concentration is so low that it is difficult or not possible to be measured by SPAD meter. Our findings demonstrated that green light, as a new tool, can be used to control the colors and nutritional components of the inner leaves of cabbages. The discoveries will help produce head vegetables with the preferred phenotype desired by consumers using a plant factory with artificial lighting.

Soymilk is a popular beverage in many countries owing to its nutrition and health effects. To increase household consumption of soymilk, instant soybeans were developed by freezing and subsequent drying pretreatment, which overcome the time‐consuming need of soaking during soymilk preparation for home making. However, compared with the traditional soymilk making, the nutritional quality and functional properties of this soymilk made from the soybean by direct grinding in water without soaking are not clear yet. Soymilk made from untreated soybeans, soaked soybeans, and soaking, freezing, and air‐drying soybeans (FADTS) were compared on their properties including nutritional components, in vitro protein digestibility, and functional components. It was found that FADTS was the best at extracting lipid and Ca, good at extracting of protein, carbohydrate, oligosaccharides, Fe, phytic acids, and tannins, and in producing soymilks with highest in vitro protein digestibility. The soluble protein and protein digestibility of FADTS (4 day) increased significantly from 44.4% and 78.5% of control to 56.2% and 85.0%, respectively. Soymilk from 4 days FADTS contained similar protein content and higher Fe content (4.40 mg/kg) compared to soaked sample (3.82 mg/kg). The results revealed that FADTS performed better at producing soymilk than untreated and soaked soybeans., Soymilk made from untreated soybeans, soaked soybeans, and soaking, freezing, and air‐drying soybeans (FADTS) were compared on their properties including nutritional components, in vitro protein digestibility, and functional components. The results revealed that FADTS performed better at producing soymilk than untreated and soaked soybeans. FADTS can be served as an instant soybean product for producing nutritional soymilk without time‐consuming soaking, which facilitate the life of modern people.

Microgreens are young, tender greens that are used to enhance the color, texture, or flavor of salads and main dishes. They can be grown in small scales and indoors, making them widely adopted by controlled environment agriculture, an indoor farming practice is particularly important for feeding increasing urban populations. Besides, microgreens are attracting more consumers’ attention due to their high nutritional value and unique sensory characteristics. This review focuses on the nutrition quality, sensory evaluation, pre- and post-harvest interventions, and health benefits of microgreens. Microgreens are rich in vitamins (e.g., vitamin C), minerals (e.g., copper and zinc), and phytochemicals, including carotenoids and phenolic compounds, which act as antioxidants in human body. Pre-harvest interventions, such as illumination, salinity stress, nutrient fortification, and natural substrates, influence the photosynthetic and metabolic activities of microgreens and were shown to improve their nutritional quality, while the effects varied among species. After harvesting, packaging method and storage temperature can influence the nutrient retention in microgreens. Both in vitro and in vivo studies have shown that microgreens have anti-inflammatory, anti-cancer, anti-bacterial, and anti-hyperglycemia properties, making it a new functional food beneficial to human health. The sensory attributes and overall acceptability and liking of microgreens are primarily influenced by their phytochemical content. Microgreens are only getting popular during the last decades and research on microgreens is still at its early stage. More studies are warranted to optimize the pre- and post-harvest practices for nutrient enhancement and retention and to explore the potential health benefits of different microgreens for the prevention and treatment of chronic diseases.

Sel‐roti is a doughnut‐like deep‐fat fried, puffed, spongy, ring‐shaped, and fermented rice‐flour confectionary indigenous to Nepal. This study was aimed to enhance the sensory and nutritional quality of Sel‐roti by incorporating soy flour.

The aim of this study was to determine the quality attributes of chickpea enriched rice noodles. Black rice-chickpea pastas were produced from different blends 10–30% of chickpea flour and black rice flour. The protein, fat, ash, Ca, Mg and P content were observed higher for chickpea flour. The noodles' proximate composition, cooking quality, and sensory characteristics were determined. Results showed an increment in protein content (9.23 – 16.54 %), fat (2.64 – 4.14 %) and ash (1.91 – 2.71 %). Fortification with chickpea flour reduced cooking time (8.5 – 7.32 min) but increased cooking loss from 2.48 to 4.18 %. Black rice noodles enriched with 30% chickpea flour was highly ranked for sensory attributes. Chickpea flour can be successfully using in the noodles formula and improving the nutritional quality of noodles. In conclusion, this study found that black rice-chickpea noodles are a nutritional alternative to traditional rice noodles, as well as providing variety to dietary categories for celiac disease sufferers.

First Nations (FN) communities have traditionally used smoke to preserve fish for food security purposes. In this study, an assessment of chemical and microbiological food safety, together with nutritional quality, was conducted on fish preserved using traditional smoke processing. High-molecular-weight polycyclic aromatic hydrocarbons (PAH) residues accounted for only 0.6% of the total PAH in traditionally fully smoked salmon, and Benzo(a)pyrene (B(a)P) was not detected in the FN smoked or commercial smoked fish, respectively. The antimicrobial activity of the solvent extracts derived from smoked fish towards Listeria innocua was very low but detectable. The practice of using full and half-smoked processing for fish reduced all of the fatty acid concentrations and also minimized the further loss of essential omega-3 fatty acids to a greater extent than non-smoked fish during storage (p < 0.05). This finding corresponded to lower (p < 0.05) lipid oxidation in smoked fish. We conclude that the benefits of reducing lipid oxidation and retaining essential fatty acids during storage, together with a potentially significant reduction in Listeria contamination, are notable benefits of traditional smoke processing. Although B(a)P was not detected in FN smoked fish, attention should be given to controlling the temperature and smoking period applied during this processing to minimize potential long-term risks associated with PAH exposure.

Freezing technology is currently an important preservation method for aquatic products. However, during the long-term freezing process proteins, which are the main components of muscle tissue, are inevitably exposed to an environment containing oxidative stress inducing changes in muscle protein structure. It leads to irreversible physical and chemical changes causing deterioration in the quality of aquatic products and reducing their nutritional value. Therefore, it is necessary clarify in depth to control oxidative damage of muscle during freezing and storage to gain more insight into the mechanisms of freezing-induced protein oxidation. The mechanism of protein oxidation in fish freezing, the effect of protein oxidation on fish quality, and the current regulatory methods for delaying protein oxidation were summarized in this paper review. The purpose is to provide a new research direction for the research and application of quality control in the process of fish frozen storage.

The tailored formulation of raw materials and the combination of grain germination and extrusion processes could be a promising strategy to achieve the desired goal of developing healthier expanded extrudates without compromising sensory properties. In this study, modifications in the nutritional, bioactive profile and physicochemical properties of corn extrudates as influenced by the complete or partial replacement by sprouted quinoa (Chenopodium quinoa Willd) and cañihua (Chenopodium pallidicaule Aellen) were investigated. A simplex centroid mixture design was used to study the effects of formulation on nutritional and physicochemical properties of extrudates, and a desirability function was applied to identify the optimal ingredient ratio in flour blends to achieve desired nutritional, texture and color goals. Partial incorporation of sprouted quinoa flour (SQF) and cañihua flour (SCF) in corn grits (CG)-based extrudates increased phytic acid (PA), total soluble phenolic compounds (TSPC), γ-aminobutyric acid (GABA) and oxygen radical antioxidant activity (ORAC) of the extrudates. Sprouted grain flour usually results in an deleterious effect physicochemical properties of extrudates, but the partial mixture of CG with SQF and SCF circumvented the negative effect of germinated flours, improving technological properties, favoring the expansion index and bulk density and increasing water solubility. Two optimal formulations were identified: 0% CG, 14% SQF and 86% SCF (OPM1) and 24% CG, 17% SQF and 59% SCF (OPM2). The optimized extrudates showed a reduced amount of starch and remarkably higher content of total dietary fiber, protein, lipids, ash, PA, TSPC, GABA and ORAC as compared to those in 100% CG extrudates. During digestion, PA, TSPC, GABA and ORAC showed good stability in physiological conditions. Higher antioxidant activity and amounts of bioaccessible TSPC and GABA were found in OPM1 and OPM2 digestates as compared to those in 100% CG extrudates., This work was funded by CONCYTEC-PROCIENCIA within the framework of call E063-2020-01-BM (C 001-2020-FONDECYT-BM).

Sheath blades are the first bamboo organ exposed to sunlight after shoots initially emerge. However, it remains uncertain whether sheath blades affect bamboo shoot growth and quality. Accordingly, this study explores variations in Phyllostachys violascens shoot growth and quality, comparing natural growth conditions to periodic sheath blade removal treatments. Results show that sheath blade removal and interactions between sheath blade removal and duration had no significant effect on the morphology, protein nutritional quality, or value of bamboo shoots. However, the length of bamboo shoot was significantly lower 4 d after treatment compared to 4 d after natural growth conditions. Moreover, sheath blade removal did have a significant effect on soluble sugar, total acid, oxalic acid, tannic acid, and cellulose content as well as sugar–acid ratios of bamboo shoots, while having no significant effect on the content and proportion of amino acid flavor compounds. Interactions between sheath blade removal and duration only had a significant effect on total acid and sugar–acid ratios. Soluble sugar, oxalic acid, tannic acid, and sugar–acid ratios increased significantly 2 d after sheath blade removal, while total acid and cellulose content decreased significantly. Lastly, soluble sugar content and sugar–acid ratios increased significantly 4 d after sheath blade removal. Findings from this study indicate that sheath blades affect shoot quality, particularly taste, which is mainly driven by carbon metabolism, but the effect of nitrogen metabolism was not obvious. This study gave a new perspective for revealing the formation mechanism of shoot quality, and also provided possible methods of improvement for the shoot quality.

The cowpea bean, recognized as Cowpea (Vigna unguiculata L. Walp.), is an important crop in low-income populations due to its nutritional properties. A mixture analysis was used to obtain the formulation of dough for frozen products, type cheese sticks, including cowpea bean flour (Vigna unguiculata). The frozen sensory evaluation was carried out using an acceptance test with a 7-point hedonic scale with 91 untrained panelists of both sexes of variable age between 17 and 62 years. Of the treatments studied, the evaluating panel showed the greatest preference, for which the largest fraction of cowpea flour constituted it. The addition of cowpea flour in a higher proportion has a significant effect on the product's nutritional and sensory properties. Cowpea flour is indicated to partially replace wheat flour in frozen cheese sticks because it improves its flavor, color, texture, and overall impression, providing a more nutritious product made with native raw materials.

Objective:To characterise the nutritional quality of food products targeted to children, we aimed: (1) to determine if the nutritional composition of child-targeted food products is different from those for the general population and (2) to verify differences in the nutrient content of child-targeted food products between three selected food categories.Design:The present study is part of the work conducted by the Food Quality Observatory, created in 2016 in the province of Quebec (Canada). Ready-to-eat (RTE) breakfast cereals (n 331), granola bars (n 310) and yoghurts and dairy desserts (n 380) were the food categories analysed.Setting:Nutritional values and all packaging information were obtained by purchasing every product available in supermarkets, grocery stores and specialty grocery stores. Free sugars were manually differentiated from total sugars for each product. Products were classified according to two targeted consumer groups: children or general population.Results:The nutrient profile of RTE breakfast cereals, granola bars and yoghurts and dairy desserts targeted to children differed from that of products intended at the general population. Child-targeted RTE breakfast cereals had the least favourable nutritional composition, with significantly higher content of carbohydrates, total sugars, free sugars and Na compared with breakfast cereals for the general population as well as child-targeted granola bars and yoghurts and dairy desserts. All child-targeted products analysed contained free sugars.Conclusions:The current study supports the relevance to further regulate marketing to children on food product packages to ensure that such marketing is not present on food products with poor nutritional quality.

Bread is a staple food in the human diet and a source of energy and nutrients for the body. The bakery process started with the homemade and artisanal way to produce bread leavened with sourdoughs started prepared from flour and water mixture. However, over the years, technological, microbiological, and nutritional aspects were studied to understand, industrialize, and select the micro-organisms involved in the bread fermentation to offer to the consumers' healthier bakery products. Therefore, this mini-review aims to describe the nutritional quality and the biotransformation observed in the flour during the fermentation process that impacts the nutrients bioaccessibility and the beneficial effects produced by this process to the final product and consumers healthy.

African breadfruit is an underutilized food security crop which is a delicacy for the Ibo ethnic group of South East Nigeria. It is commonly found in West and Central Africa. It is an evergreen large tree that bears about 20–30 pods containing edible seeds, annually. The edible seeds are used as specialty dishes by the Ibo tribe of South East Nigeria. African breadfruit meals have high dietetic value. The pods, leaves and roots are use in traditional medicine. The leaves are particularly rich in carbohydrates, phytochemicals (flavonoids, phenols, cardiac glycosides and anthraquinones) and minerals. These constituents contribute to its antioxidant, antimicrobial and wound healing properties. The stem bark extract is used as a cough remedy and has antimicrobial properties. The water and ethanoic extracts of the root possess antihyperglycaemic properties and also discourage the development of secondary complications of type 2 diabetes. Many of the perceived medicinal and chemical properties have not been scientifically investigated. Although other members of the mulberry family (especially the Artocarpus species) have received some research attention, Treculia africana remains underutilized despite its great potentials as a food security and medicinal crop.

This study aimed to determine the discriminatory power of textural features to differentiate the sorghum grains subjected to normal, mild deficit, and severe deficit irrigation. The studies were carried out with the use of image processing, discrimination analysis, analysis of variance and cluster analysis using the selected texture parameters calculate for images from individual color channels L, a, b, R, G, B, U, V, S, X, Y and Z. The results indicated that different levels of irrigation can discriminate the sorghum grain with an accuracy of up to about 100%. Most of the genotypes for each level of irrigation were different in the terms of values of textural features and formed separate homogeneous groups. Drought is one of the limiting factors contributing to a decrease in sorghum grain productivity and nutritional quality, especially when it is cultivated in a marginal area. Therefore, low-quality grains produced under water stress should be recognized before they enter into the food and feed chain. The application of image analysis based on textures of sorghum grain images proved to be useful for the discrimination of sorghum grains subjected to drought stress. The applied procedure provided the fast, objective results that may be applied in practice for screening distinguishing the sorghum grains with different irrigation levels.

Fermented cereal-based gruels with poor nutritional value form a major component of the diet of infants during the transition phase of childhood. With the recent security challenges affecting people in the north- east region of Nigeria, food security is at stake, malnutrition is common among infants and young children while reliance on UNICEF for supplies of ready- to- use therapeutic foods is not a long-term solution. A complementary food blend was prepared following the guideline of WHO/FAO on infants’ nutritional requirements in a 60:20:20 ratio from fermented yellow maize (improved variety), roasted soybean and fishmeal respectively. All the sample materials were pre-processed by either fermentation, drying or roasting prior to food blend formulation. Standard methods (AOAC) were used to evaluate the nutritional values of the raw and processed materials and the formulated complementary food blend. Water absorption capacity of the fermented yellow maize significantly decreased (P< 0.05) with decrease in pH and increase in titratable acidity from 20% - 51% (0 – 72h). The carbohydrate (64.35±0.03%) and protein contents (14.55±0.03% and energy value (351.64±0.03 Kcal/100g) of the complementary food blend was closely comparable to the commercial complementary food blend cerelac® (Carbohydrate 69.00%, Protein 15.0%, and energy 426.00 Kcal/100g) and satisfied the needs of infants. The low moisture content (3.1±0.02%) exhibited by the complementary food blend might give a good storage stability. The iron level of the complementary food blend (40.33± 0.03%) was higher than that of the commercial complementary food blend celerac® (10.0%), though the levels of potassium, zinc and calcium were lower. Microbial analysis showed no contamination with pathogenic organisms in the formulated food blend. The formulated complementary food blend met the WHO estimated requirements of infant 6 – 23 months in terms of nutritional quality and may therefore be a good substitute to the imported, expensive alternatives.

Recently, there has been an increase in demand for gluten-free (GF) products due to the growing number of gluten-intolerant and healthy individuals choosing to follow a gluten-free diet. Gluten-free bread (GFB) is a staple food product; therefore, many recent studies have reported the nutritional properties of GFB. However, an overview of the current ingredients and nutritional labeling of GFB worldwide has not yet been provided. This review aimed to gather the latest information regarding the most used ingredients in GFB formulations and the nutritional quality of these products from different countries, based on studies published in the last decade (2010-2020). Our analysis showed that GFB had a lower protein and a higher fat content than gluten-containing bread, and the dietary fiber content was highly variable between countries. Some studies have revealed a high glycaemic index in most products, which is associated with the extensive use of rice flour and starch as the main ingredients in GFB formulation. Label information presented significant differences from the data obtained through the chemical analysis of fiber and other nutritional components. Micronutrient fortification is not common in the GFB. The nutritional quality of commercial GFB is a crucial issue that needs to be addressed.

In this study, chiffon cakes were fortified with potato flakes and raw dehydrated potato flour (RDPF) prepared by freeze-drying and hot air drying. The dough’s rheological properties demonstrate that potato flakes are unsuitable for making chiffon cakes, especially at percentages of 30 and 50%. Adding RDPFs decreased the dough height and adhesiveness but increased the hardness slightly compared with the control. Supplementing with potato flakes has the most influence on cake textural properties, especially at percentages of 30 and 50%, which correspondingly reduces the sensory evaluation score. All the RDPF cake formulations exhibited higher comprehensive nutritional value in terms of protein, fat, dietary fiber, minerals, and amino acids. The cake formulations containing RDPF obtained by hot air drying contained the lowest carbohydrate contents.

The whole milk spiked with sulfamethazine was treated under thermal and pulsed electric field processing for maximum reduction. The low-temperature long-time (LTLT, 62.5 °C for 30 min), high-temperature short time (HTST, 72 °C for 15 s) pasteurization and ultra-high temperature processing (UHT, 138 °C for 2 s) resulted in the reduction of sulfamethazine 7.3, 5.2 and 4.6% respectively. PEF and combination treatment (thermal + PEF) were found to reduce sulfamethazine content in milk by 67–72% and 73–76% respectively. Combined treatment of milk resulted in a higher percentage of reduction. Similar predicted and actual values proved that they fit the linear regression model and successful application of pulsed electric field technology in reducing antibiotic residues. PEF and mild thermal treatment can be a promising technology to reduce the antibiotic residues with ensuring minimal negative impact on the nutritional quality of food.

Manufacture of virtually all milk and dairy products involves heat treatment, with the goal of killing bacteria and inactivating enzymes, among other things. Thermal reactions, on the other hand, might result in undesired changes such as protein denaturation, non-enzymatic browning, the creation of a cooked flavour, nutritional quality loss (vitamins and volatile chemicals), bacterial inhibitor inactivation, and rennet ability deterioration. Over and above the thermal processes are characterized as the most energy-consuming technologies in the food industry. As a result, a number of contemporary developments and non-thermal technologies have been investigated and found to have no negative impact on milk quality; for example, High hydrostatic pressure (HHP), Ionization Radiation, Ultrasounds (US), Pulsed electric fields (PEF), carbon dioxide, High Voltage Arc Discharge (HVAD) , Cold Plasma (CP), Bio-control cultures, Non-conventional chemical reagents, Ozonation, and Protective and preserving packaging technologies for processing milk have devised to replace heat treatment. The focus of this review is on certain non-thermal processing innovation as an emerging technology and its application on dairy products.

The study was done to analyze the effects of various blanching conditions on nutritional quality of differently dried green peas using three different methods namely, open sun drying, cabinet drying and drying in solar dehydrator. Samples were analyzed for various parameters such as, moisture content, rehydration ratio, linear shrinkage ratio, green color ratio, total chlorophyll, ascorbic acid, microbial load and sensory analysis. Various mathematical models were used to study the drying behavior of green pea samples. With the help of various statistical parameters, the best model for different drying conditions was found out. Chemically blanched peas dried in cabinet dryer were considered best among all the treated peas dried under different drying conditions and least acceptance was given to un-blanched open sun dried peas. Quality and acceptability of solar dried peas were higher than open sun drying but lower than cabinet drying. While considering models, Logarithmic model gave a very good performance on all the statistical parameters. So, it can be used to predict the drying behavior of green peas.
