The deterioration in fruit quality of commercial tomatoes is a major concern of modern tomato breeding. However, the metabolism and genetics of fruit quality are poorly understood. Here, we performed transgenic and molecular biology experiments to reveal that tomato phytoene synthase 1 (SlPSY1) is responsible for the accumulation of an important flavor chemical, 6-methyl-5-hepten-2-one (MHO). To dissect the function of SlPSY1 in regulating fruit quality, we generated and analyzed a dataset encompassing over 2 000 compounds detected by GCeMS and LC-MS/MS along with transcriptomic data. The combined results illustrated that SlPSY1 deficiency imparts novel flavor to yellow tomatoes with 236 volatiles significantly changed and improves fruit firmness, possibly due to accumulation of seven cutins. Further analysis indicated SlPSY1 is essential for carotenoid-derived metabolite biosynthesis by catalyzing prephytoene-PP (PPPP) to 15-cis-phytoene. Notably, we showed that SlPSY1 can influence the metabolic flux between carotenoid and flavonoid pathways, and this metabolic flux was confirmed by silencing SlCHS1. Our study provided insights into the multiple effects of SlPSY1 on tomato fruit metabolome and highlights the potential to produce high-quality fruit by rational design of SlPSY1 expression.

Rationale: Flavors can alter the orosensory properties of tobacco products. Specifically, flavors can serve as an oral cue for smokeless tobacco products. Objectives: We aimed to investigate the impact of oral vanillin, the principal chemical of vanilla flavor in tobacco products, on nicotine's taste, and nicotine choice, intake, and seeking behaviors. Methods: Experiments were performed in young adult Sprague Dawley rats. We employed a two-bottle free-choice test (2BC) to measure the preference for different concentrations of vanillin and its effect on nicotine preference. To explore the long-term effects of early exposure to sweetened vanillin, we utilized a combined 2BC and intraoral self-administration (IOSA) model. We assessed the nicotine taking and seeking behaviors in the presence or absence of vanillin. We performed a taste reactivity test (TRT) to quantify liking (ingestive) and disliking (aversive) taste responses to oral nicotine with or without vanillin. Results: In 2BC, female rats preferred vanillin containing solutions more than their male counterparts. In IOSA, vanillin alone and in combination with nicotine led to greater IOSA compared to water. Female rats self-administered vanillin plus nicotine more than male rats. Vanillin increased motivation to nicotine taking, but only in females. In TRT, vanillin increased nicotine's ingestive responses but blocked aversive responses in both sexes. Conclusions: These results indicate that vanilla flavor can increase oral nicotine intake. It can also increase liking and decrease disliking of nicotine's taste. Furthermore, the impact of vanilla flavor on nicotine taste and nicotine choice, intake, and seeking behaviors is concentration and sex dependent. [ABSTRACT FROM AUTHOR]

Background: Sweet taste administration before dental injections helps to control associated pain in children. Aim: To evaluate the efficacy of using a sugar‐free flavor on pain perception during dental injections. Design: Children (n = 84) aged 4–9 (mean 6.71 ± 1.55) years who required buccal infiltration bilaterally participated in this split‐mouth randomized crossover study. On the test side (flavor visit), infiltration injections were applied after receiving a sugar‐free flavor. On the control side (no flavor visit), sterile water was administered. Demographic characteristics, body mass index (BMI), and sweet taste preference (STP) were recorded. Pain perception during injection was measured using heart rate (HR), sound, eyes, and motor (SEM) scale, and Wong–Baker Faces pain scale (WBFPS). Results: Most children had healthy weight (72.6%) and equal STP (32.1%). In the test side, mean HR during injection, HR differences before and during injection, and SEM scores were significantly lower (p <.001, for all). There was no significant difference in the WBFPS between both visits. Flavor had a significant effect on pain reduction (p =.001 for HR, p =.000 for SEM), whereas age, gender, BMI, STP, and treatment side did not. Treatment sequence had a significant effect on total SEM scores (p =.021); children who received the flavor during their first visit had lower SEM scores. Conclusion: Using a sugar‐free flavor before dental injections helps in reducing associated pain in children. [ABSTRACT FROM AUTHOR]

The objective of this study was to investigate influences of polyvinyl alcohol/ hydroxypropyl methyl cellulose/roselle anthocyanin–based (PHR) film on shrimp biochemical and flavor profiles. PHR films led to better preservation behaviors, and the film contained the highest anthocyanin contents exhibited the best biochemical properties with total volatile basic nitrogen (TVB-N) content of 47.87 ± 3.57 mg/100 g, thiobarbituric acid (TBA) value of 0.55 ± 0.05 mg MDA/kg, and total viable counts (TVC) value of 6.63 ± 0.11 log CFU/g. The PHR film had obvious effects on the metabolism pathway of flavor compounds. It could modify flavor profiles by increasing pleasant components such as glutamate, glycine, decanal, and 3-methylbutanal, while decreasing the off-related components like histidine, indole, and trimethylamine. Furthermore, the characteristic flavor markers which were highly correlated with chemical spoilage indexes were identified, and their concentration variations suggested that PHR film could affect their formation and release behavior. Meanwhile, the possible mechanism of PHR film in shelf-life prolongation and flavor profile enhancement was proposed. In conclusion, the PHR film had promising potentials in extension of shelf-life and modification of flavor profiles of refrigerated shrimp. [ABSTRACT FROM AUTHOR]

We study various aspects of global symmetries in five-dimensional superconformal field theories. Whenever a supersymmetry-preserving relevant deformation is available, the infrared gauge theory description might exhibit a finite order mixed 't Hooft anomaly between a 1-form symmetry and the instantonic symmetry. This anomaly constrains the flavor symmetry group acting faithfully on the SCFT and the consistency of certain RG flows. As an additional example, we consider the instructive case of three-dimensional N = 4 SQED. Finally, we discuss the compatibility between conformal invariance and the presence of 1-form and 2-group global symmetries. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lettuce holds a prominent position in the year‐round supply of vegetables, offering a rich array of health‐beneficial substances, such as dietary fiber, phenolic compounds, lactucopicrin and lactucin. As such, its flavor has garnered increasing attention. Balancing the enhancement of beneficial compounds with the reduction of undesirable taste is a key focus of scientific research. To investigate short‐term management to improve the nutritional quality and flavor of lettuce, combinations of different light intensities (200, 500 and 800 μm ol m−2 s−1) and temperatures (10 and 22 °C) were applied separately to 'Lollo Rosso' and 'Little Butter Lettuce' for 7 days before harvest. RESULTS: The results obtained showed that increasing light intensity at low temperatures decreased nitrate content and increased soluble sugar, soluble protein, anthocyanin and phenolic compound content. In the case of lettuce flavor, the bitterness‐related metabolites such as lactucin and lactucopicrin were reduced with high light intensity at a low temperature of 10 °C. With this combination, the fructose and glucose contents increased, significantly improving lettuce flavor. CONCLUSION: Higher light intensity combined with low temperature for 7 days before harvest effectively improved the nutritional quality and flavor of lettuce, suggesting its great potential for use in horticultural practices. © 2024 Society of Chemical Industry.

BACKGROUND: Wheat bran (WB) is a byproduct of refined wheat flour production with poor edible taste and low economic value. Herein, the WB was micronized via airflow superfine pulverization (ASP), and the effects of the ASP conditions on its particle size, nutritive compositions, whiteness, hydration characteristics, moisture distribution, microstructure, cation exchange capacity, volatile flavor components, and other characteristics were investigated. RESULTS: Reducing the rotational speed of the ASP screw and increasing the number of pulverizations significantly decreased the median particle size Dx(50) of WB to a minimum of 12.97 ± 0.19 μm (P < 0.05), increased the soluble dietary fiber content from 55.05 ± 2.94 to 106.86 ± 1.60 mg g−1, and improved the whiteness and water solubility index. In addition, the water holding capacity and oil holding capacity were significantly reduced (P < 0.05), while the cation exchange and swelling capacities first increased and then decreased. Up to about 70% of water in WB exists as bound water. As the Dx(50) of WB decreased, the content of bound and immobile water increased, while the free water decreased from 14.37 ± 1.21% to 7.59 ± 1.03%. Furthermore, WB was micronized and the particles became smaller and more evenly distributed. Using gas chromatography–ion mobility spectrometry, a total of 37 volatile compounds in micronized WB (including 10 aldehydes, 9 esters, 7 alcohols, and several acids, furans, ethers, aldehydes, esters, and alcohols) were identified as the main volatile compounds of WB. CONCLUSION: Collectively, ASP improved the physicochemical properties of WB. This study provides theoretical references for the use of ASP to improve the utilization and edibility of WB. © 2024 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

With the healthy food decision trends and conflicting taste preferences, wide array of experience augmentation strategies have been developed to maintain healthy diet without reducing sensory expectations. Employed appropriate physical, chemical, biological, and psychophysics strategies in the preparation and consumption of enhanced-flavor dairy products were assessed in this review. Multimodal perception to adjust flavor at the neurosensory level through visual, olfactory, and individual differences have been successfully applied to reduce sugar content in milk dessert products targeted at children to avoid the childhood obesity epidemic. Natural plant-based homogenates can also replace sugar to achieve healthy and all-natural goals in dairy production. Innovative and emerging physical methods used as alternative to traditional thermal processing to remove odors of fermented dairy products and contribute to new flavor, nutty, savory, and fresh. This review indicated that flavor experience augmentation strategies show promise in predicting flavor formation mechanisms, facilitating the synthesis of desirable flavor compounds, and tackling the contradictory information between health and flavor.

A large amount of poultry blood is annually generated, and currently underutilized or largely disposed of as waste, resulting in environmental pollution and waste of protein resources. As one of the main by-products during the poultry slaughter process, the produced poultry blood can serve as a promising food ingredient due to its excellent functional properties and abundant source of essential amino acids, bioactive peptides and functional components. This work provides a comprehensive summary of recent research progress in the composition, functional and bioactive properties, as well as the functional components of poultry blood. Furthermore, the main preparation methods of poultry blood-derived peptides and their bioactivities were reviewed. In addition, their potential applications in the food industry were discussed. Overall, poultry blood is characterized by excellent functionalities, including solubility, gelation, foaming, and emulsifying properties. The major preparation methods for poultry blood-derived peptides include enzymatic hydrolysis, ultrasound-assisted enzymatic methods, macroporous adsorbent resins, and subcritical water hydrolysis. Poultry blood-derived peptides exhibit diverse bioactivities. Their metallic off-flavors and bitterness can be improved by exopeptidase treatment, Maillard reaction, and plastein reaction. In addition, poultry blood is also abundant in functional components such as hemoglobin, superoxide dismutase, immunoglobulin, and thrombin. [ABSTRACT FROM AUTHOR]

Korean food has garnered global interest, especially after COVID-19, with a significant increase in demand for K-Food staples like bulgogi, tteokbokki, bibimbap, kimchi, and galbi, as well as related YouTube content. A key ingredient that enhances the deliciousness of Korean cuisine is Gochujang. Gochujang, with its unique taste and aroma, is an unparalleled fermented spice seasoning, adding spiciness and a special flavor to a variety of dishes. Made from ingredients such as Meju, glutinous rice, red pepper powder, malt, and salt, Gochujang has a rich history spanning thousands of years and is celebrated for its spicy and sweet flavor. Gochujang is differentiated by commercial and traditional manufacturing methods. Traditional Gochujang is produced through natural fermentation using glutinous rice, malt, Meju powder, salt, and red pepper powder. Conversely, commercial production blends traditional methods with modern industrial techniques, utilizing pure microbial cultures like Aspergillus oryzae and Bacillus subtilis as starters to meet mass production demands. Beyond its culinary uses, Gochujang is recognized globally for its nutritional value and health benefits. Fermentation enhances its health functionality by creating new substances or converting fermentation metabolites. Notable compounds synthesized during fermentation include capsaicin from red pepper powder and non-glycoside isoflavones from Meju, which are linked to antiobesity, antidiabetic, antiatherosclerosis, and anticancer effects. Gochujang also helps restore intestinal microbial balance, promoting gut health. This review aims to explore the historical background of Gochujang, its production methods, flavor characteristics, nutritional composition, health benefits, and the expansion of culinary research involving Gochujang.

Condiments (such as sodium chloride and glutamate sodium) cause consumers to ingest too much sodium and may lead to a variety of diseases, thus decreasing their quality of life. Recently, a salt reduction strategy using flavor peptides has been established. However, the development of this strategy has not been well adopted by the food industry. There is an acute need to screen for peptides with salty and umami taste, and to understand their taste characteristic and taste mechanism. This review provides a thorough analysis of the literature on flavor peptides with sodium-reducing ability, involving their preparation, taste characteristic, taste mechanism and applications in the food industry. Flavor peptides come from a wide range of sources and can be sourced abundantly from natural foods. Flavor peptides with salty and umami tastes are mainly composed of umami amino acids. Differences in amino acid sequences, spatial structures and food matrices will cause different tastes in flavor peptides, mostly attributed to the interaction between peptides and taste receptors. In addition to being used in condiments, flavor peptides have also anti-hypertensive, anti-inflammatory and anti-oxidant abilities, offering the potential to be used as functional ingredients, thus making their future in the food industry extremely promising.

Background: Mutton quality is closely related to genetic variants and gene expression alterations during growth and development, resulting in differences in nutritional values, flavor, and odor. Results: We first evaluated and compared the composition of crude protein, crude fat, cholesterol, amino acid (AA), and fatty acid (FA) in the longissimus dorsi muscle of Guizhou black goats (GZB, n = 5) and Yunshang black goats (YBG, n = 6). The contents of cholesterol and FA related to odor in GZB were significantly lower than that in YBG, while the concentrations of umami amino acids and intramuscular fat were significantly higher in GZB. Furthermore, structural variants (SVs) in the genomes of GZB (n = 30) and YBG (n = 11) were explored. It was found that some regions in Chr 10/12/18 were densely involved with a large number of SVs in the genomes of GZB and YBG. By setting FST ≥ 0.25, we got 837 stratified SVs, of which 25 SVs (involved in 12 genes, e.g., CORO1A, CLIC6, PCSK2, and TMEM9) were limited in GZB. Functional enrichment analysis of 14 protein-coding genes (e.g., ENPEP, LIPC, ABCA5, and SLC6A15) revealed multiple terms and pathways related with metabolisms of AA, FA, and cholesterol. The SVs (n = 10) obtained by the whole genome resequencing were confirmed in percentages of 36.67 to 86.67% (n = 96) by PCR method. The SVa and SVd polymorphisms indicated a moderate negative correlation with HMGCS1 activity (n = 17). Conclusion: This study is the first to comprehensively reveal potential SVs related to mutton nutritional values, flavor, and odor based on genomic compare between two black goat breeds with closely genetic relationship. The SVs generated in this study provide a data resource for deeper studies to understand the genomic characteristics and possible evolutionary outcomes with better nutritional values, flavor and extremely light odor.

Myofibrillar proteins primarily consist of myosin, actin, myogenin, and actomyosin. These proteins form complex networks within muscle fibers and are crucial to the physical and chemical properties of meat. Additionally, myofibrillar proteins serve as significant substrates for the adsorption of volatile flavor compounds, including aldehydes, alcohols, ketones, and sulfur and nitrogen compounds, which contribute to the overall flavor profile of meat products. A series of chemical reactions occur during the processing, storage, and transportation of meat products. Oxidation is one of the most significant reactions. Oxidative modification can alter the physical and chemical properties of proteins, ultimately impacting the sensory quality of meat products, including flavor, taste, and color. In recent years, considerable attention has been focused on the effects of protein oxidation on meat quality and its regulation. This study investigates the impact of myofibrillar protein oxidation on the sensory attributes of meat products by analyzing the oxidation processes and the factors that initiate myofibrillar protein oxidation. Additionally, it explores the control of myofibrillar protein oxidation and its implications on the sensory properties of meat products, providing theoretical insights relevant to meat processing methods and quality control procedures.

The high sodium content in meat products poses health risks to consumers and does not align with modern green and healthy living standards. Current strategies for directly reducing the sodium content in meat products are limited by their negative impact on the sensory or quality attributes of the products. In recent years, there has been great interest in applying ultrasound technology to reduce sodium content. This paper discusses the advantages and disadvantages of current mainstream strategies for reducing the sodium content in meat products, as well as the potential mechanisms by which ultrasound-assisted marination improves the quality of low-salt meat products. The main findings indicate that ultrasound, through its cavitation and mechanical effects, facilitates the transition of proteins from stable insoluble aggregates to stable soluble complexes, exposing more hydrophilic groups and, thus, enhancing protein solubility. At the same time, ultrasound promotes a greater number of proteins to participate in the formation of interfacial layers, thereby increasing emulsifying activity. Furthermore, ultrasound treatment promotes the interaction between proteins and water, leading to partial unfolding of protein chains, which allows polar residues to more readily capture water in the gel, thereby improving the water-holding capacity of the gel. These effects will contribute to the formation of high-quality low-salt meat products. However, variations in the frequency, intensity, and duration of ultrasound treatment can lead to differing effects on the quality improvement of low-salt meat products. [ABSTRACT FROM AUTHOR]

Freeze drying (FD) is a technique used to preserve the bioactive content and flavor of samples. Foods with a short shelf life due to nature have been preserved via FD in recent years. The success of the drying technique is thanks to the high retention ability of the bioactive compounds and the flavor of the sample. However, the high cost and energy consumption of FD limit its usage in several fields. Freezing, primary drying, and secondary drying, which take place in the same device, are the stages of FD. In addition, several parameters, including pretreatment, size, temperature, sample species, time, and pressure, affect the FD process. These parameters are controlled to increase the effectiveness of FD on the samples. Moreover, FD has been compared with other drying techniques including hot air drying, microwave drying, vacuum drying, and solar drying to determine its protective capability. It has also been applied to the valorization of waste products, which is a common problem worldwide. For valorization, microencapsulation and powder production have been achieved using FD. In recent years, studies on the effects and use of FD on various materials increased, providing new aspects for the future of science and food industry. [ABSTRACT FROM AUTHOR]

Dry hopping is a technique of adding hops to beer during or after fermentation to enhance aroma and flavor. It results in an undesired phenomenon called hop creep: attenuated beer undergoes a secondary fermentation. The aim of the research was to evaluate practical aspects of hop creep. In laboratory conditions hop creep was evaluated in pasteurized and unpasteurized beers and the effect of hop separation from beer after 3 days of dry hopping was verified. Hop creep analyzed in beers brewed on a pilot scale (20 L) and an industrial scale (10 hL) allowed to observe the course of hop creep in various scales of production, and to compare the process in pressure and non-pressure conditions. The decrease in the apparent extract of beer caused by hop creep occurs only in unpasteurized beers, separation of hops after 3 days reduces the extent of hop creep. Hop creep occurs faster in top-fermented beers and is equally intense regardless of the scale of production. The use of pressure conditions during dry hopping extends the duration of the hop creep without affecting the final extract content of the beer (the final attenuation of beer is the same in pressure and non-pressure conditions).

Chemical analysis showed that pH, b* values, myosin turbidity, carbonyl content, and surface hydrophobicity elevated in hooked, trawl‐net, and radar‐net hairtail (Trichiurus haumela, HH, TH, and RH) muscles with the prolonged cryopreservation time (‐18℃, 120 d). In contrast, L*, a* values, textural properties, and myosin solubility existed decreasing trends. Microstructural results showed that freezing resulted in disordered myofibrils, decreased collagen fibers, widened myofibrillar space, and increased fragmentation in hairtail muscles. Furthermore, volatile flavor analysis suggested that aldehydes, ketones, alcohols, and amines were the key factors for the overall flavor formation in hairtails during cold storage. Pearson correlation coefficient analysis revealed that the color, texture, and protein oxidation had close correlations with VOCs. Among the three different kinds of hairtail, fresh RH fillets exhibited an attractive aroma with high economic value, long‐term frozen TH muscle tissues were prone to deterioration in texture, microstructure, and flavor, and the HH samples presented stable quality characteristics and storage performance.

Red sour soup is a Guizhou specialty condiment made by the natural fermentation of tomatoes and chili. In this study, three components (tomato acid, chili acid, and tomato and chili mixed acid) of split‐fermented red sour soup were explored to compare the quality characteristics and microbial communities in the middle and late fermentation stages. The titratable acidity of mixed acids was lower than that of tomato acid and chili acid in the middle stage, but it was significantly increased in the late stage. The cell viability of lactic acid bacteria was mostly higher than that of yeasts during the whole fermentation. Also significantly increased in the late stage of fermentation were sensory scores and the signal intensity of sour substances. However, the signal intensity of both bitter and salty substances decreased, and the total amount of free amino acids was reduced. In addition, the antioxidant capacity of the samples and the dominant microorganisms were different between the two fermentation stages, Lactobacillus and Kazachstania were the key common genus of the different components of split‐fermented red sour soup. It is anticipated that this study would provide us an insight into the quality characteristics and microbial communities of split‐fermented red sour soup. [ABSTRACT FROM AUTHOR]

Bean paste is a traditional Chinese fermented condiment, which is loved by consumers for its pleasant flavor and nutritional properties. However, the microbial communities and related flavor compounds in bean paste remain unclear. We studied the correlation between the core functional microorganisms and flavor compounds in bean paste samples at different fermentation stages. Bacterial and fungal communities changed significantly during fermentation. The results indicated that the dominant bacterial genera were Staphylococcus, Lactococcus, and Bacillus. The dominant fungi were Aspergillus and Lichtheimia. During the early and late stages of bean paste fermentation, alcohols, hydrocarbons, esters, and phenols were the main flavor compounds detected. The types and proportions of alcohols and esters in the bean pastes fermented for different durations were similar, whereas the relative contents of phenols and hydrocarbons were higher in the later stages of fermentation. Correlation analysis revealed that core functional microorganisms played a key role in the fermentation process, and the potential correlation between bacterial genera and flavors was stronger than that of fungal genera. Staphylococcus abundance was significantly correlated with the flavor levels of ethyl oleate, ç‐pinene, diallyl disulfide, á‐myrcene, D‐limonene, and tetradecanoic acid, ethyl ester. The abundance of Aspergillus and Lichtheimia was significantly correlated with the flavor levels of á‐myrcene, ç‐pinene, and DL‐3‐phenyllactic acid. This study explored the relationship between microorganisms and flavor compounds in bean paste to deepen our understanding of the mechanism of flavor formation for bean paste. [ABSTRACT FROM AUTHOR]

Lactic acid is closely linked to the safety and quality of baijiu, the traditional Chinese fermented alcoholic beverage. Produced by lactic acid bacteria during fermentation, it creates an acidic environment that inhibits the growth of spoilage organisms and harmful microbes, thereby enhancing the safety and stability of the final product. Additionally, lactic acid is a key contributor to baijiu's flavor profile, providing a smooth and rounded taste. Its levels can significantly impact consumer experience. An excess of lactic acid can result in a sour, undesirable flavor, while insufficient levels may lead to a flat and less appealing taste. Maintaining balanced lactic acid levels is crucial for ensuring that baijiu is both safe and enjoyable to drink, ultimately contributing to the product's success and marketability. This paper reviews the mechanisms of lactic acid production in baijiu, examines its effects on flavor and the potential causes of imbalances, explores regulatory measures for controlling lactic acid during brewing, and discusses the impact of these measures on baijiu's quality, taste, and yield, along with practical applications by various distilleries. The goal of this paper is to provide a reference for regulating lactic acid in the baijiu production processes. [ABSTRACT FROM AUTHOR]

In order to efficiently utilize the apricot kernel flour (AKF), the composite bread with the partial substitute of wheat flour was developed by evaluating its effects of protein content in AKF on the bread quality properties including the texture, color, specific volume and baking loss. In addition, the functional properties of protein in AKF were also investigated so as to understand its correlation with the composite bread quality. The results indicate that apricot kernel flour with different protein contents had a substantial impact on the composite bread's quality. At the same time, the emulsifying activity, water absorption capacity of water, foaming capacity and surface hydrophobicity of proteins in AKF are significantly correlated with the composite bread's quality characteristics, these factors may be the important impact of the composite bread's quality. Additionally, the composite bread made by 10% replacement of wheat flour with the AKF of medium-fat content (MAF) was bright in color, soft, had a small baking loss, a unique apricot kernel flavor and improved sensory properties. In summary, all the results indicate that the apricot kernel meal could be efficiently utilized by replacing a certain wheat flour to make the composite bread reducing its waste and Enriching bread nutrition.

In this study, a high vacuum flavor extraction (HVE) device was developed to address the limitations of traditional extraction methods, such as extended extraction times and artifact generation during high-temperature processes. Firstly, the repeatability and precision of the HVE method were evaluated through quantitative analysis of twelve volatile odor compounds across seven replicate extractions using gas chromatography–flame ionization detection (GC-FID). The results showed that the HVE system achieved a mean relative standard deviation (RSD) of 11.60 ± 1.79% and a recovery rate of 90.55 ± 4.56%, demonstrating its precision and reproducibility. Secondly, the performance of HVE was compared with solvent-assisted flavor evaporation (SAFE) and simultaneous distillation–extraction (SDE) for extracting flavor compounds from fried tilapia mince. The results indicated that HVE was more effective, particularly in extracting aldehydes and pyrazines, which are key contributors to the flavor profile. Finally, sensory evaluations supported these findings, showing that the odor profiles obtained through HVE were most similar to the original sample, with a similarity score of 72.55%, compared to 69.25% for SAFE and 60.29% for SDE. These findings suggest that HVE is a suitable method for the extraction and analysis of volatile compounds in complex food matrices such as fried tilapia mince. [ABSTRACT FROM AUTHOR]

Rice-flavor baijiu is a distilled Chinese spirit prepared from Xiaoqu culture. However, its dull taste may be a market limitation. In order to enhance the flavor profile of rice-flavor baijiu, two ester-producing yeast strains (Saccharomyces cerevisiae and Cyberlindnera fabianii) were inoculated for fermentation. At the end of the fermentation, the total alcohol and ester contents had also increased by 43.3% and 29.8%, respectively, and the number of ester species had increased by eight. Additionally, eleven flavor substances had significant contributions in the inoculated fermentation process, including several different esters and alcohols. A macrogenomic analysis revealed that the majority of the gene abundances associated with the alcohol, acid, and ester pathways were elevated by the third day of inoculated fermentation, and greater abundances of Saccharomyces cerevisiae, Cyberlindnera fabianii, Lichtheimia ramosa, Rhizopus delemar, and Rhizopus oryzaefive, annotated with these genes, were observed from either the pre-fermentation stage or post-fermentation stage. The results demonstrate that two added strains are associated with an increase in the content of the flavor substances. These findings may prove beneficial in enhancing the quality of rice-flavor baijiu through using inoculated fermentation with ester-producing yeast. [ABSTRACT FROM AUTHOR]

This study explored the use of lucuma fruit powder in an ice cream formulation for the US market. Six ice cream prototypes were developed using five different lucuma fruit powder variants. A central location test was conducted with frequent ice cream consumers (n = 106) to assess acceptance, attribute intensity rating, ideal intensity levels, and purchase intent against a control sample with caramel flavor. The mean overall liking score for all lucuma ice creams was moderate. The overall, aroma, and flavor liking scores were significantly higher (p < 0.05) for lucuma ice cream samples, whereas the control sample was liked significantly more for texture. The Terrasoul variant of lucuma ice cream was the most liked among all samples, and the control was liked the least. Only the Terrasoul ice cream sample was successful in delivering significantly strong caramel, fruit, and sweet flavor levels; the other lucuma ice cream samples were more comparable to the control. The inclusion of lucuma powder increased powdery mouthfeel perception, negatively impacting texture liking. Consumers perceived all ice cream samples to be weak in flavor and fell short of delivering ideal levels. The US consumers had low–moderate food neophobia scores for lucuma fruit, with 57% showing interest in buying lucuma ice creams. [ABSTRACT FROM AUTHOR]

Meat Standards Australia (MSA) sensory protocols have been effectively utilized in beef for international consumers employing several cooking methods. Our objective was to compare the consumer response of Australian and American consumers to paired beef brisket samples utilizing a newly developed low and slow cooking method. Briskets were collected from Australian carcasses with diverse eating quality. Half of the briskets (n = 24) were retained in Australia and their pair was exported to Texas for consumer sensory testing. Naïve consumers (Australia; n = 240) and familiar consumers (USA; n = 240) evaluated paired barbequed briskets for tenderness, juiciness, flavor liking, and overall liking from 0 to 100 using a visual analogue scale, and a weighted composite meat quality score was later calculated. Australian consumers scored briskets lower for tenderness (−4.84 ± 1.70 points) and juiciness (−4.44 ± 1.55 points) and higher for flavor liking (3.48 ± 1.58 points); however, there was no difference between the countries for overall liking (p = 0.75) and combined meat quality score (p = 0.88). Differences between Australian and US consumers' evaluations indicate that there is an impact of cultural background, potentially driven by Australia's naivety to the low and slow barbeque cooking method.

Baijiu is popular with a long history and balanced flavor. Flavor type is the most widely used classification mode for Baijiu. However, the evolutionary relationships of Baijiu flavor types and the differential markers between flavor types are still unclear, significantly impacting the development of the Baijiu industry. In this study, a total of 319 trace components were identified using gas chromatography–olfactometry–mass spectrometry and gas chromatography–mass spectrometry. Among them, 91 trace components with high odor active values or taste active values were recognized as flavor components. Then random forests were conducted to screen differential markers between the derived and basic flavor types, while a principal component analysis assessed their effectiveness in distinguishing the flavor types of Baijiu. Finally, 19 differential markers (including 3-methylbutyric acid, pentanoic acid, 2-butanol, 2,3-butanediol, ethyl pro-panoate, isobutyl acetate, ethyl butanoate, ethyl hexanoate, ethyl heptanoate, ethyl lactate, ethyl 2-hydroxy butanoate, isopentyl hexanoate, ethyl nonanoate, isopropyl myristate, ethyl tetradecanoate, ethyl benzoate, 2,4-di-t-butylphenol, 2-methylbutanal and 3-octanone) were screened and proven to effectively reveal the evolution of Baijiu flavor types; these were further verified as key differential markers using addition tests and a correlation analysis.

This study evaluated the changes in physicochemical properties and appearance quality of long-grain rice during the grinding process using image technologies and aimed to provide reference for future research. The brown rice milling process was divided into three stages, and flatbed scanning, scanning electron microscopy (SEM), X-ray micro-computed tomography (micro-CT), low-field nuclear magic resonance (LF-NMR), and headspace–gas chromatography–ion mobility spectrometry (HS–GC–IMS) were employed to examine the physicochemical and volatile properties of the samples. Results revealed a continuous increase in the degree of milling, with a broken rice rate and a whiteness value increasing by 50.84% and 21.13%, respectively, compared with those during the initial stage; dietary fiber and vitamin B1 contents were reduced by 54.41% and 66.67%, respectively. The image results visualized showed that the cortex of brown rice was gradually peeled off with the increase in milling degree; the cortical thickness was gradually reduced, the endosperm was gradually exposed, and the surface was smoother and shinier. T2 populations exhibited a shift toward longer relaxation times, followed by a decrease in relaxation time during the milling process. Additionally, 31 target compounds impacting rice flavor, mainly ketones, alcohols, and esters, were identified, and the concentration of volatile substances in the B region decreased with the reduction in the bran layer; the concentration of volatile substances in the C region provided rice flavor, which increased with the milling process. This study showed changes in the physicochemical properties and appearance quality of long-grain brown rice during milling. Furthermore, the use of various image processing techniques offers significant insights for optimizing processing parameters and enhancing overall quality and taste. [ABSTRACT FROM AUTHOR]

Poria cocos (Schw.) wolf (P. cocos) is an important medicinal material with both therapeutic and edible properties. This study investigated volatile constituents, amino acids, proteins, polysaccharides, triterpenoid ingredients, and alcohol-soluble extracts on P. cocos during eight drying processes. A total of 47 volatile components were found and identified; the main volatile components of shade drying (SD) and hot-air drying at 50 °C (HD50) were esters and alcohols, while for drying in hot air at 60 °C~100 °C (△ = 10 °C) and infrared drying (ID), the main compounds were aldehydes and hydrocarbons. The amino acids in P. cocos remained the same when dried with various methods. Compared with SD samples, with the temperature increase, the content of amino acids showed a trend of first decreasing and then increasing, while the content trend of proteins was the opposite. The HD70 samples had the highest content of polysaccharide, triterpenoid ingredients, alcohol-soluble extracts, and antioxidant activity. Furthermore, volatile compounds showed a correlation between non-volatile constituents. This research provides evidence that the aroma, active components, and activity of P. cocos were affected by the drying method. [ABSTRACT FROM AUTHOR]

A novel Qingke Baijiu was produced by the process of light-aroma Baijiu combined with high-temperature stacking process and using highland barley of Tibet as material. Three kinds of Qingke Baijiu samples were evaluated by quantitative descriptive analysis, and analyzed by liquid-liquid extraction combined with gas chromatography-mass spectrometry and gas chromatography-olfactometry-mass spectrometry and analyzed by partial least squares regression analysis to clarify the aroma characteristic of the novel Qingke Baijiu and to investigate the influence of different manufacturing process. A total of 139 volatile compounds and 57 aroma compounds were detected in three samples, which included 11 aroma active compounds with odor active value (OAV) greater than 1. The total concentration of volatile compounds was 1.4 times higher after secondary fermentation. The sorghum and Zao aromas increased in the samples after secondary fermentation, where ethyl caprylate, ethyl caproate, ethyl isovalerate, and guaiacol were the corresponding key differential compounds. The sorghum and Zao aromas decreased after high-temperature stacking process, while floral aroma increased. Compared with the samples without high-temperature stacking process, the OAV of isoamyl acetate, guaiacol and 4-methylguaiacol increased, while the OAV of ethyl butyrate, ethyl caproate, and ethyl caprylate declined. After high-temperature stacking process, the concentration of isoamyl acetate increased, which lead to stronger floral aroma, and the concentration of butyric acid, ethyl caproate, ethyl caprylate, and ethyl decanoate declined, which lead to weaker sorghum aroma.

This study aimed to study the effects of three current popular high-temperature treatments (electric roasting, air frying and superheated steam) on the physicochemical properties and taste quality of grass carp meat. Physicochemical properties were analyzed by measuring pH, water holding capacity, color value, thiobarbituric acid reactive substance and protein carbonyl content of fish meat. Taste quality was characterized by measuring the free amino acids content and flavor nucleotides content of fish meat. The results showed that compared with the raw grass carp meat in the control group, the indexes of physicochemical properties of grass carp meat processed by different high-temperature treatments were significantly increased in different degrees (P<0.05), which preliminarily revealed that the quality of fish meat would change differently under different high-temperature environments. After that, through the statistical analysis of two typical taste substances, free amino acids and flavor nucleotides, it was concluded that the content of taste substances in grass carp meat would also increase significantly after three high-temperature treatments (P<0.05). Among them, the change of air frying group was the most obvious, and its highest contents of free amino acids and flavor nucleotides were up to 338.78 mg/ 100 g and 1050.61 mg/100 g, which made it have the highest umami degree in the later stage. According to the comprehensive evaluation, three treatments all did not produce adverse performance in terms of physicochemical properties, air frying group performed well in terms of taste quality, indicating that grass carp meat treated by air frying had better edible quality.

BACKGROUND: Traditional sun‐drying aquatic products are popular and recognized by customers, owing to their unique flavor and long‐term preservation. However, the product quality and production efficiency cannot be guaranteed. Cololabis saira is rich in unsaturated fatty acids, which are susceptible to hyperoxidation during the drying process. This study aimed to make clear the role of ultraviolet (UV) radiation in flavor formation during drying processes of Cololabis saira to develop a modern drying technology. RESULTS: Lipid oxidation analysis revealed that moderate hydrolytic oxidation occurred in the UV‐assisted cold‐air drying group due to the combined influence of UV and cold‐air circulation, resulting in the thiobarbituric acid reactive substances value being higher than that of cold‐air drying group but lower than the natural drying group. Hexanal, heptanal, cis‐4‐heptenal, octanal, nonanal, (trans,trans)‐2,4‐heptadienal, (trans,trans)‐2,6‐nonanedial, 1‐octen‐3‐ol, heptanol, 2,3‐pentanedione, 3,5‐octadien‐2‐one and trimethylamine were identified as the characteristic flavor odor‐active compounds present in all Cololabis saira samples. Yet, during the natural drying process, sunlight promoted the lipid oxidation, resulting in the highest degree of lipid oxidation among three drying methods. Light and heat promoted lipid oxidation in Cololabis saira prepared through natural drying process, leading to a large accumulation of volatile compounds, such as 3‐methylbutyraldehyde, 2,3‐pentanedione, 1‐propanol, and 3‐pentanone. Cold air circulation inhibited lipid oxidation to some extent, resulting in a blander flavor profile. More cis‐4‐heptenal, cis‐2‐heptenal, octanal and 2‐ethylfuran accumulated during the UV‐assisted cold‐air drying process, enriching its greasy flavor and burnt flavor. CONCLUSION: UV‐assisted cold‐air drying could promote moderate lipid oxidation, which is beneficial for improving product flavor. To sum up, UV radiation played a crucial role in the flavor formation during the drying process of Cololabis saira. © 2024 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

Changes in the different stages of fruit processing are becoming a differentiating factor in coffee quality. Currently, generating delays in the processing of the fruit, that is, reserve, is a practice that can modify the sensory profile of the beverage. In this study, the fruit was reserved in three stages of maturity, two temperatures (15° and 20°C) and at two timepoints (24 and 48 h), establishing its chemical composition and sensory characteristics using analytical techniques such as liquid and gas chromatography. The state of maturity 1 showed an effect on malic and quinic acids due to the interaction of temperature and reserve time, while stage of maturity 3 showed an effect on glucose and fructose. The state of maturity 2 showed an effect of the reserve time on the same compounds of states 1 and 3, in addition to the content of defective beans and sucrose. The sensory quality expressed as the total SCA (Specialty Coffee Association) score and the attributes did not show treatments effect, the reserve of the fruit under the evaluated conditions presents an effect on the descriptors of the flavor. Extending the fruit reserve time from 24 to 48 h showed an increase in the groups of flavor descriptors associated with fruit and red fruits from 33.33 to 66.66% and from 34.04 to 65.95%. This implies that the constituent parts of the fruit such as the exocarp and mesocarp interact with the bean, leading to changes in the chemical composition and the improvement of the qualitative complexity of the sensory quality. This is a consequence of the increase in the frequency of the flavor descriptors of the fruit and red fruit category. [ABSTRACT FROM AUTHOR]

Grape pomace (GP) is a waste product of the winemaking process and has been proposed as a nutritionally beneficial ingredient, as it contains phenolic compounds, dietary fiber, and antioxidant activity. It can be a polarizing ingredient due to its flavor components. Familiarity has been found to influence consumers' preferences and sensory perception of food. A sensory test was conducted to evaluate the acceptance, sensory perception, and emotional response to pasta sauces containing GP (3% [3GP], 6% [6GP], 9% [9GP] by volume and control without GP addition). The sensory trials included wine consumers (n = 44) and nonconsumers of wine (n = 58) to determine how consumers' familiarity with the flavor properties of GP influenced their perception of the pasta sauce. Overall, the addition of GP decreased the liking scores of the GP‐containing sauces, but the wine consumers' hedonic scores for the control, 3GP, and 9GP were significantly higher than the nonconsumers. Both consumer groups identified that the samples with a higher amount of GP addition were associated with sour, bitter, astringency, grainy, and gritty attributes. However, the wine consumers used more positive emotions to describe their emotional response to the GP‐containing samples. The study identified that GP led to off‐flavors and textures in the pasta sauces. Practical Application: GP is currently a waste product, but it has many nutritional benefits. Consumers are increasingly looking for nutritional benefits from their food. When incorporated into pasta sauces, GP decreased the acceptance of the pasta sauce and negatively impacted the flavor and texture. Familiarity has been found to impact consumer acceptance, and wine consumers had a more positive emotional response and higher hedonic scores in response to the GP‐containing pasta sauce than nonconsumers of wine.

Buttermilk has many functional and nutritional impacts due to the presence of phospholipids and proteins in the membrane of fat cells. Based on this, the present study was designed to investigate the use of sweet buttermilk in free -fat strained yogurt (FFSY). For this purpose, ratios of 5, 10, and 15% (w/w) sweet buttermilk were used in the preparation of the yogurt base. This research was conducted in the form of a completely random design. On days 0, 5, 10, 15, and 20, the pH, dry matter (%), and protein (%) of the FFSY were evaluated. In addition, the viscosity (mPa.s) and the sensory analysis of the FFSY, including appearance, odor, taste & flavor, mouthfeel and, and general acceptance, were examined during the first and 20th days. The results showed that the pH of the samples containing buttermilk decreased more during shelf life (P > 0.05). Dry matter (%) decreased with increasing the buttermilk (%), although no significant change in dry matter was observed during the shelf life (P > 0.05). With increasing buttermilk (%), the protein (%) decreased and it did not change over the shelf life (P > 0.05). By reducing the buttermilk (%), the viscosity (mPa.s) also decreased (P > 0.05). The sensory evaluation test showed the FFSY containing 10% (w/w) buttermilk possessed the highest score for taste & flavor, mouthfeel, and general acceptance. Therefore, this treatment was selected as the best sample. In general, the present study showed that the use of buttermilk in the production of FFSY is functionally and practically useful.

Introduction: Citrus hybrids with Poncirus trifoliata L. Raf. introgression have gained interest due to their tolerance to Huanglongbing (HLB), a devastating disease for Florida citrus agriculture. While these hybrids inherit disease tolerance from P. trifoliata, they sometimes also suffer from undesirable off-flavors. Methods: A selection of thirteen genotypes were harvested over the 2020-2021 and 2021-2022 seasons. Their juices were evaluated by a trained sensory panel and were comprehensively analyzed for their chemical makeup, including soluble solids content (SSC), titratable acidity (TA), volatiles, flavonoids and limonoids. Results & discussion: Overall, along with the commercial orange cultivars 'Valencia' and 'Hamlin', the HLB-tolerant Poncirus hybrid 'US SunDragon,' and the mandarin hybrids Sugar Belle¬, FF-5-51-2, and 'US Superna' had positive citrus flavor quality. Esters, some sesquiterpenes, along with flavonoids, eriocitrin and quercetin-3-(3R-glucosylrutinoside), were positively correlated with orange flavor while b-ionone and eucalyptol were highly abundant in the mandarins. The flavonoid linarin, was more abundant in Poncirus hybrids with off-flavors than in the Poncirus hybrid 'US SunDragon', having high orange flavor. Two mandarin hybrids, FF-5-6-36 and FTP-6-32-67, were not bitter at harvest, but the juice exhibited delayed bitterness after storage at -20°C, which was associated with significant increases of limonin, nomilin, naringenin, and prunin. Interestingly, during freezer storage, a newly identified flavonoid in citrus, tricin-C-hexoside, increased dramatically across all of the genotypes. The identification of diseasetolerant hybrids with satisfactory flavor quality at juicing as well as after storage where delayed bitterness may develop, has great significance for future breeding efforts for fresh fruit or for use in stand-alone juice/juice blends.

Background: Historically, tobacco companies have used flavored tobacco products to enhance the appeal of tobacco consumption, encourage initiation and experimentation of tobacco use, and contribute to sustained tobacco use. While flavored tobacco products are regulated in several countries, there is no existing regulation on flavored tobacco products in the Philippines, specifically for cigarettes and cigars. This study aims to update evidence on the flavored tobacco product landscape in the Philippines by assessing both the flavor descriptors and flavor imagery featured on cigarette and cigar packaging. Results: We collected 106 cigarette and cigar products from four major cities in the National Capital Region, Balanced Luzon, Visayas, and Mindanao. Of these 106 cigarette and cigar products, 62 (58.49%) had flavor descriptors. Three crushable capsule products did not feature any flavor descriptor but were included for flavor imagery examination. We identified five categories of flavor descriptors: menthol, concept descriptors, tobacco, beverages, and other flavors. Out of 62 packs, ten featured more than one flavor descriptor on the packaging. Menthol flavor descriptors comprised the majority of flavor descriptors. Imagery and other graphic elements closely resonate with and enhance the flavor descriptors found on these packs. Conclusions: This study aimed to update the evidence on the flavored tobacco product landscape in the Philippines and address their absence of regulation. Regulating flavored tobacco products requires a comprehensive policy approach complemented by complete enforcement. Flavor substances, flavor descriptors, and flavor imagery must be regulated altogether; however, it is ideal to enforce a ban on flavored tobacco products in compliance with the WHO FCTC, to which the Philippines is a signatory. Policymakers should consider plain packaging as an intervention to eliminate the appeals associated with flavored tobacco products. [ABSTRACT FROM AUTHOR]
