Katjang goat meat has the potential to be used for emulsified meat product production but the suitable starch type to be applied as the Aller is unknown. The present study was undertaken to evaluate the effect of various starches on the quality characteristic of Katjang goat meat emulsion. Katjang goat meat emulsion was prepared by incorporating various starches viz., tapioca starch (TS), sago starch (SS), and wheat starch (WS), as Aller by replacing lean meat. The developed emulsion samples were evaluated for physiochemical, proximate, colour, texture, and gel strength. The addition of TS into meat emulsion results in the most stable emulsion as exhibited by the lowest total expressible fluid (%TEF), expressible fat (%EFAT), and cooking loss. There was no significant (p>0.05) difference for the pH, water holding capacity (WHC), texture profile analysis (TPA), and colour values of all the samples. The incorporation of SS in the formulation decreased (p<0.05) the shear force and work of shearing. In conclusion, the incorporation of TS was found optimum to formulate goat meat emulsion with better quality characteristics. [ABSTRACT FROM AUTHOR]

The use of pork obtained from intensively growing hybrid animals as the main raw material in meat processing, in particular sausage production, is accompanied by undesirable variability of consumer characteristics of sausage products and a decrease in the economic indicators of enterprise performance. The main technological disadvantages of processed pork are reduced water-binding capacity and significant loss of meat fluid, which in practice is usually compensated by the increased use of food additives and non-meat ingredients. The aim of the study was to assess the possibility of targeted improvement of the technological properties of minced pork using a proteolytic enzyme of animal origin. Model samples of minced meat were developed and cured for 24 hours at a temperature of 4 °C. The following control samples were used: minced meat with the addition of 2% edible salt and minced meat with the addition of 2% edible salt and 0.2% sodium bicarbonate. Moreover, 0.0001% chymotrypsin was added to the test samples containing similar curing ingredients. During electrophoretic study, in samples with the enzyme, an increase in low-molecular fractions (20 kDa, 15 kDa and lower) was observed, which indicated the manifestation of proteolytic activity of chymotrypsin in model systems. Enzymatic treatment led to an increase in pH and water-binding capacity. Cooking loss was reduced by 3 to 6 times, compared to Control 1. After cooking, histological studies of model systems showed that the test samples subjected to enzymatic treatment were characterized by a denser arrangement of structural elements, less pronounced cellular components of muscle tissue and the presence of glutin formed as a result of protein breakdown, filling the microcapillaries. Thus, the use of an enzyme preparation provides an opportunity for targeted improvement of the technological properties of pork obtained from intensively growing hybrid animals.

[Objective] This study aimed to study the effect of thermal ultrasound on the physicochemical properties of mung bean milk liquid and the quality of yuba. [Methods] Using mung bean as raw material, mung bean slurry was treated with different thermal ultrasonic conditions and made into yuba. [Results] Compared with untreated slurry, with the increase of temperature, the increase in particle size and thiol content showed a trend of first increasing and then decreasing. At 50 ℃, the particle size of 100 and 150 W increased from 156.27 nm to 208.06 nm and 191.96 nm, and the thiol content increased from 16.83 μmol/L increased to 22.63 μmol/L and 25.35 μmol/L. The endogenous fluorescence spectrum indicates that the higher the temperature, the more tryptophan residues are present in the slurry. The mass of yuba at 100 and 150 W increased from 4.09 g to 5.26 g and 5.08 g, the elasticity increased from 0.08 mm to 0.16 mm and 0.13 mm, and the cooking loss rate decreased from 13.28% to 7.51% and 8.02%, among which the texture characteristics of yuba at 100 W increased significantly, and the cooking loss rate decreased significantly. [Conclusion] Thermo ultrasonic treatment can improve the physical and chemical properties of mung bean milk liquid and the quality characteristics of yuba.

Abstract. The study aim was to determine the impact of storage period on veined rapa whelk (Rapana venosa) meat, either chilled for 6 days or frozen for 3, 6, 9 and 12 months on its technological traits, chemical composition and fatty acid profile. Rapa whelks were collected by divers in June 2021 from the Black Sea, one nautical mile off the Bulgarian coast. A total of 60 kg of rapa whelks were collected from a depth of 10-15 m. The water holding capacity, cooking and roasting losses, meat proximate composition and fatty acid profile were analysed in the laboratories of the Faculty of Agriculture, Trakia University. Statistically significantly (P

This study was carried out to evaluate the effects of sesame (Sesamum indicum L.) oil cake on pasta processing and the functional characteristics of the end product. The pasta produced from wheat flour fortified with 5, 7.5, 10, 12.5, and 15% (w/w) sesame oil cake showed a significant increase in total protein (i.e., ranging from 12.3 and 16.0 g/100 g), lipid (i.e., 3-fold) and crude fiber (i.e., 0.58 to 0.91 g/100 g) contents with the increasing addition of sesame oil cake. Consistograph tests showed that the pressure maximum decreased significantly from 267.2 kPa for the wheat flour dough (control) to 157.6 kPa upon the addition of 15% (w/w) sesame oil cake to wheat flour. Drop-in pressure after 250 and 450 s was lower for the control sample than for those containing 5, 7.5, 10, 12.5, and 15% (w/w) sesame oil cake. The elasticity value for the control dough was 500.1 Pa, and it was reduced to 392.3 Pa with the addition of 15% (w/w) sesame oil cake to wheat flour resulting also in a significant reduction in the extensibility. The pasta from the flour blend with 7.5% (w/w) sesame oil cake exhibited the highest cooking loss, at 5.40 g/100 g. Sensorial evaluation of the flavor and stickiness of pasta produced from the flour blends containing up to 10% (w/w) of sesame oil cake was satisfactory and recommended to open the door for industrial utilization of such valuable and nutritious by-products. Sesame components and gluten network interactions are believed to play a key role in modifying pasta's functional characteristics and require more investigation. [ABSTRACT FROM AUTHOR]

This study investigated the relationship of carcass characteristics such as hot carcass weight and back fat thickness (BFT) and the pH of semispinalis capitis (SC) with the cooking loss (CL) of pork shoulder butt and the CL and Warner–Bratzler shear force (WBSF) of belly. BFT was correlated with the CLs of the butt slices (rs = −0.30) and the belly slices (rs = −0.27 to −0.32). The pH of the SC muscle showed a correlation with the CLs of the butt slices (rs = −0.45) and the belly slices of the 6th and 11th thoracic vertebrae (rs = −0.28 to −0.33). Additionally, the correlations (rs = 0.62 to 0.77) were observed in the CLs among the belly slices. However, the WBSF of the belly slices did not show correlations with others. Therefore, the pH of the SC muscle as well as BFT can be used to obtain information on the CL of shoulder butts and bellies in carcasses.

A study was conducted on development of composite flour noodles using indigenous food grains of NorthEast India and assessment of their quality. The composite flour noodles were prepared in a single screw cold extruder using wheat flour (WF), black aromatic rice flour (BRF), white sticky rice flour (WRF), and millet flour (MF) in different proportion. The physical properties, cooking characteristics, textural characteristics, and sensory qualities of the noodle were examined. The results showed that the noodles' bulk density varied between 0.4 and 0.5 g ml-1 and their moisture content ranged from 8.63 to 8.91 (% wb). The cooking loss, cooking yield and the water absorption capacity of the noodles ranged from 7.9%-13.4%, 271.5%-370.9% and 1.72-2.71 g g-1, respectively. As the amounts of MF and BRF reduced, a decrease in the hardness and adhesiveness of the noodles was observed. Based on the sensory evaluation, composite flour noodle having maximum amount of BRF and MF was found to be the most liked sample. In contrast to their lack of significance at 95 percent confidence level for water absorption capacity, different proportions of WF, BRF, WRF, and MF have a substantial impact on colour change, bulk density, cooking loss, and cooking yield.

The study investigated the optimal swelling method for dried Abalone rugosa by assessing the impact of water and alkali swelling methods on various parameters including swelling rate, centrifugal loss, cooking loss, pH, texture characteristics, color, and water distribution of abalone. The findings revealed that water swelled abalone exhibited higher water holding capacity and lower pH compared to alkali swelled abalone. Moreover, the texture characteristics of abalone were significantly altered by the swelling process; specifically, water swelled abalone showed remarkable improvements in tenderness and elasticity as opposed to alkali swelled counterparts which displayed significantly lower (p < 0.05) hardness, cohesiveness, and chewiness values. Additionally, water swelling resulted in reduced water fluidity and shortened initial relaxation times of abalone samples, leading to a higher content of immobile water while decreasing the content of free water. Based on these outcomes, it can be concluded that employing the water swelling method enhances both quality and moisture retention capacity of swollen Abalone when compared to using alkaline swelling.

This study aimed to elucidate the effects of supplementation of Capsicum frutescens L. or chili pepper (ChP) and Curcuma longa L. or turmeric (T) powders combination in total mixed ration (TMR) on texture profile, water holding capacity (WHC) and oxidative stability of beef during days 0, 5 and 10 of retail display. The experiment was carried out on 16 crossbred bulls (Brahman and Charolais) of about 2 years in age. The bulls were randomly assigned to 4 dietary treatment groups as follows: 1) TMR as control, 2) TMR + 1%ChP powder, 3) TMR + 1%T powder, and 4) TMR supplemented with a mixed powder of 1%ChP + 1%T, over a 6 months feeding period. The results revealed that the hardness and gumminess of control beef were higher than other groups, and the cohesiveness of beef from cattle fed a mixed powder of 1%ChP + 1%T was lower than other groups (P<0.05). Regarding WHC, the results showed that, on days 0 and 5 of storage, the control group meat had higher cooking losses than either the 1%T or a mixture of 1%ChP + 1%T groups (P<0.05). Also, on 0 and 5 days of retail display, the 1%ChP + 1%T group showed the highest antioxidant activity when compared to other groups (P<0.05). As for the lipid oxidation in beef, on day 5 of storage MDA level in control beef was higher than the 1%T or a mixture of 1%ChP + 1%T groups (P<0.05). It can be concluded that the combination of chili pepper and turmeric powder in TMR can improve texture, water holding capacity, and oxidative stability of beef during refrigerated storage.

Pulsed electric fields (PEF) is a non-thermal technology that is still looking for implementation on a larger scale by the meat industry. Its sustainability dimension, which is much improved by lowering energy consumption and shortening treatment times compared to conventional technologies, may tip the scale for successfully shifting the PEF technology readiness level to industrial application. This review provides an overview of the latest knowledge, and in the last three years, on using PEF processing in meat to enhance its functionality, nutrition, texture, colour and sensory quality. PEF treatment could improve meat's protein digestibility and solubility while having no negative impact on its nutritional value. However, controversial indications regarding PEF's effect on meat cooking loss are reported. Colour changes of meat after PEF treatment are directly proportional to the extent of total specific energy inputs used in the processing, while the effect of PEF on meat sensory properties is yet to be discovered. Since the ability of PEF to achieve its desired goals is dependent on many different factors, including the type of meat, electric field strength, number and duration of electric pulses, and others, more studies are needed to fully understand specific conditions that can be dependably applied in the meat industry. pulsed electric fields improve functional quality of meat pulsed electric fields do not negatively affect nutritional quality of meat pulsed electric fields sustainability research in meat industry is hugely missing [ABSTRACT FROM AUTHOR]

The use of toxic and less bioavailable inorganic selenium can now be substituted with an alternative organic source obtained from bacterial species to benefit human and animal nutrition. This study investigates the effects of selenium sources on laying hen's meat quality. A total of 144 Mid-Producing Lohman Brown Classic laying hens, aged 23 weeks, were divided into four experimental groups (each with 36 hens) based on the form of Se supplementation (no Se supplementation, 0.3 mg/kg of inorganic Se in the form of sodium selenite, 0.3 mg/kg organic Se from Sel-Plex, Alltech Inc., Nicholasville, KY), and 0.3 mg/kg organic Se from Stenotrophomonas maltophilia (bacterial organic Se). The trial period was seventeen weeks, after which the hens were slaughtered and breast muscles sampled at week 40. The results showed that dietary Se supplementation enhanced (P<0.05) cooking loss, drip loss, and meat tenderness of breast muscles significantly in the enriched bacterial Se group compared to the inorganic and basal diet groups. Se sources also had a significant impact (P<0.05) on the colour (lightness, redness, and yellowness) of the breast meat. Bacterial organic Se supplementation reduced cooking loss and drip loss, and it improved the tenderness and breast meat colour of Lohman brown laying hens. [ABSTRACT FROM AUTHOR]

ABSTRACT: In the current scientific literature, one can find >100 different methods to evaluate water-holding capacity in fresh and cooked meat. The main concepts are based on removing some of the water by either gravity, application of pressure (e.g., centrifugal force), and heating while measuring water exudate to predict the water holding capacity (WHC) during storage, processing, cooking, and/or distribution. More sophisticated methods include nuclear magnetic resonance (NMR) in which the relaxation of water molecules within a meat protein/gel system is measured to predict how the water (75% in lean meat) will behave during processing. Overall, the number of tests reported is also so high because there are quite big variations in test conditions (e.g., 750–30,000 g for centrifugal testing). The aim of this article (outcome of a symposium on methods for poultry meat characterization) is to help the reader navigate through the different setups and suggest standardized testing based on scientific principles. The recommended WHC test is the application of low centrifugal force (750 g so sample is not permanently deformed) to a protein gel, while the sample is placed on a screen platform to avoid reabsorbing the liquid separating during the slowing down of the centrifuge. It is also recognized that some meat samples (e.g., high in fat) might require a different g-force, so it is recommended to employ both the conditions mentioned above and the lab-specific conditions. Our overall goal should always be to increase uniformity in test procedures, which will enhance our capabilities to compare results among research groups.

ABSTRACT This study aimed to evaluate the effect of different pre-slaughter fasting times on live weight and meat quality of broiler chickens slaughtered at 35 and 42 days of age. Treatments consisted of four, eight, 12, and 16 hours of total fasting before slaughter. Eight birds of each sex were slaughtered at each time of fasting. Regression analysis indicated that the longer the fasting time, the greater the weight reduction in both males and females (35/42 days). However, analysis of variance highlighted no weight reduction (P>0.05) for four, eight, and 12 hours of fasting in males slaughtered at 35 and 42 days of age and in females at 35 days. However, females slaughtered at 42 days of age showed no differences (P>0.05) for four and eight hours of fasting. After 16 hours of fasting, both males and females slaughtered at 35 and 42 days of age showed higher weight reductions (P0.05) were observed for male and female birds of 35 and 42 days of age, respectively. Regarding meat quality, no changes (P>0.05) were found for CL and WHC in males and females at 35 and 42 days of age, respectively.

The present work was to compare quality differences of the duck leg roasted with or without tinfoil paper wrapping using electric oven. The sensory characteristics, cooking loss, fatty acids, amino acids, and volatile flavor composition in the meat of the two roasted duck leg samples were analyzed. In comparison, the duck leg roasted without tinfoil paper wrapping had greater roasted aroma and cooking loss, while that with paper wrapping was more tender and had lower cooking loss. No matter with or without tinfoil paper wrapping, both fatty acid contents and amino acid contents in the meat were increased after roasting. The sample roasted without tinfoil paper wrapping had higher values in polyunsaturated fatty acids content to saturated fatty acids content (PUFA/SFA) and essential amino acid content to total amino acid content (EAA/TAA). Head-space solid phase microextraction and gas chromatography-mass spectrometry (HS-SPME/GC-MS) analysis identified in total 44 volatile compounds in the two samples while those like aldehydes, alcohols, ketones, etc. had greater amounts in the sample roasted without tinfoil paper wrapping. Orthogonal partial least squares discriminant analysis (OPLS-DA) suggested that hexadecanal, octanal, tetradecanal, (E,E)-2,4-decadienal, pentanal, hexanal, etc. (VIP>1) could be markers to differentiate volatile flavor composition of the two samples. Moreover, gas chromatography-olfactometry of aroma extract dilution analysis (AEDA/GC-O) identified 22 odor-active compounds (i.e. odorants) in the two samples with aldehydes being the highest number followed by sulfur-containing compounds and pyrazines. Overall, the odor-active compounds found by GC-O were similar in the two samples whereas they had different flavor dilution factors. Then aroma profile of the two samples was compared by radar charts based on the compounds of higher dilution factors representing the roasted duck leg odors. It suggested harmonious and more prominent roasted and fatty aromas pertaining to the sample without tinfoil paper wrapping，which agreed with the sensory analysis results.

Laying roosters as meat producers have not been used optimally, due to the low tenderness value. Increasing the proportion of shrinkage cooked using enzymes will increase the value of tenderness. This study used a completely randomized design (CRD) with 4 treatments and 4 replications. The treatments used were as follows P0 = control, P1 = 10 ml of papain enzyme, P2 = 15 ml of papain enzyme, and P3 = 20 ml of papain enzyme. The parameters observed in this study were cooking losses and pH. The results showed that the injection of the papain enzyme significantly (P0.01) increased the value of cooking loss in meat, where the lowest value for cooking loss in treatment P0 was 30.9%, while the highest value for cooking loss in treatment P1 was 36.6%. The statistical analysis results showed that the injection of the papain enzyme in laying roosters had a significant effect (P0.05) on the pH value of the meat, where the highest value for the pH level was in the P3 treatment, namely 5.72 with a dose of 20 ml of papain enzyme. The lowest value was in the P0 treatment, namely 5.54 without the administration of the papain enzyme.

Aim of study: To evaluate the effects of adding Lactobacillus acidophilus (LA), Spirulina platensis (SP) and the encapsulation of LA on the relative weights of carcass parts and meat quality of broilers subjected to heat stress. Area of study: The work was performed at the University of Jiroft, Iran. Material and methods: Two hundred forty 1-day-old male broilers (Ross 308) were used in a completely randomized design, with six treatments and four replicates (cages, 10 birds per cage). Dietary treatments included: (i) corn-soybean as control diet (CON), (ii) 0.02% LA, (iii) 1% SP, (iv) 0.02% LA + 1% SP, (v) 0.02% of encapsulated LA, and (vi) 0.02% encapsulated LA + 1% SP. Main results: The relative weight of the carcass increased in all experimental groups except in the 0.02% LA encapsulated group (p˂0.05). Birds fed diets containing LA+SP (0.02% LA+ 1%SP and 0.02% LA encapsulated+1% SP) had a significantly higher relative weight of the breast (p˂0.05). Dietary supplementation with SP, LA+SP, and encapsulated LA+SP significantly increased water holding capacity and decreased cook loss, respectively (p˂0.05), whereas dietary LA+SP and encapsulated LA+SP decreased drip loss (p

This study aimed to investigate the loss of riboflavin in meats by different cooking methods and determine the bioaccessibility of riboflavin in meat products using a simulated in vitro gastrointestinal system. The measured amount of riboflavin in raw meats was in the range of 75–195 µg/100 g. Cooking loss of riboflavin were between 5.09–89.23%. Riboflavin bioaccessibility was between 10–60%. In this study, it was revealed that riboflavin content in meats, which is an important part of nutrition, was affected by in vitro digestion. It is a well-known fact that nutrient losses can occur with cooking food. [ABSTRACT FROM AUTHOR]

Production and processing factors that affect native goat meat quality are non-existent in the literature. The current study explored age, sex, and chilling effects on 48 goat carcasses cut in half by halal standards and shifting one half immediately to a walk-in chiller at 0-4°C [rapid chilling (RC)] and the other half at 26 ± 2°C [delayed chilling (DC)]. Results showed that Warner Bratzler Shear Force (WBSF) was significantly affected by RC. Cooking loss and color (L*) parameters were significantly higher in young male animals. Chroma values were significantly higher in DC. In conclusion, DC enhances meat quality and tenderness. [ABSTRACT FROM AUTHOR]

In this study, the heating penetration in salmon muscle tissue was evaluated during ohmic heating (OH) at 20 kHz. The electrical conductivities (ECs) in five muscle-tissue sections (fat content from 7.85 to 21.15 %) of salmon were measured under different conditions of applied frequency (50 Hz–20 kHz), temperature (5–70 °C), and direction of the electric current (parallel or series) in relation to the muscle arrangement. Significant differences in the ECs of the five sections were found, especially at high frequencies. A lower fat content and the parallel current direction resulted in higher ECs than a higher fat content and the series current direction. Empirical equations were derived to determine the EC values of all five sections of the salmon fillet based on their temperature dependence. The cooking losses after OH processes were low in the order of parallel < series < minced. These results are of potential value for the design of the OH process for salmon-based products.

Lupin flour could have the potential to be an alternative to meat products due to its nutritional, health, and functional properties. A factorial experiment was performed to investigate the effect of lupin seed flour treatment (without, steaming, and roasting), meat substitution level with lupin seed flour (0, 5, 10, and 15%), and the interaction between them on the quality attributes of cooked beef burger by measuring CIELAB color, texture profile analysis (TPA), chemical composition (before and after cooking), and cooking properties (cooking loss, fat and moisture retention, and shrinkage). Based on the results of the factorial experiment, a completely randomized design was used to evaluate the sensory attributes of selected treatments. The different substitution levels mainly affected CIELAB color values, chemical composition, and cooking properties. On the other hand, the interaction effect between substitution level and treatment affected TPA. Considering all results, steaming treatment and a substitution level of 10% were selected as the best treatment to produce beef burgers. In comparison to the control burger, the developed burger had higher values of L* (increased by 21.26%), b* (increased by 32.94%), and moisture retention (increased by 37.85%); lower values of fat (decreased by 16.11%), protein (decreased by 6.37%), cooking loss (decreased by 43.22%), shrinkage (decreased 19.69%), and moisture content (decreased by 2.64%); and nonsignificantly different values with other tests performed. This study demonstrated that the incorporation of lupin flour in beef burgers could have the potential to substitute meat, create an alternative burger with a high percentage of plant protein, and expand the application of lupin flour in the food industry.

This work investigated the effects of the usage of colored corn as a replacement for 50% and 100% yellow corn in the diet of Japanese quail. Two hundred and forty-day-old Japanese quails were indiscriminately separated into four experimental groups consisting of six replicates each containing 10 quails. Experimental groups designed: the control group (C) (basal diet-0% colored corn, vaccinated), negative control group (NC) (basal diet-0% colored corn, no vaccine), 50% CC group (basal diet-50% colored corn, vaccinated), and 100% CC group (basal diet-100% colored corn, vaccinated). At the end of the 35-day period, the highest body weight and body weight gain (BWG) were recorded in the 50% CC (P < 0.05). The highest feed intake (FI) was recorded in the 100% CC group, the lowest FI in C (P > 0.05), and the best feed conversion ratio (FCR) in the 50% CC group (P < 0.05). While L* was not affected, a* and b* values were significantly affected by feeding colored corn (P < 0.05). Meat pH, cooking loss (CL), and water holding capacity (WHC) values were significantly affected, and the highest pH and CL values were in the C group and the highest WHC value in NC (P < 0.05). Colored corn had no influence on MDA7th concentration of breast meat. The antibody titers against NDV were significantly superior in the vaccinated groups than in the NC (P < 0.05). In conclusion, the use of colored corn in quail had an affirmative effect on meat quality and growth performance but not on the immune response of quail against NDV. [ABSTRACT FROM AUTHOR]

Poultry meat is consumed worldwide and its production is expected to increase in the upcoming years. Genetic selection in poultry focused on growth rate, feed conversion, and breast yield, resulting in the occurrence of white striping and wooden breast abnormalities and, most recently, spaghetti meat. These myopathies affect the quality traits of raw meat, including pH, color, water holding capacity, and cooking loss, which limit its further processing and decrease consumer acceptance. Additionally, the effects of myopathies on the chemical composition, i.e., reduced protein and essential amino acid content and increased fat contents, impair to some extent the nutritional value of the meat.

Context: Heating of meat leads to structural changes reflected in the juiciness and the tenderness of the cooked meat. Aims: This study aimed to characterise the effect of prolonged ageing and cooking on pork-quality traits. Methods: Longissimus lumborum samples from 12 carcasses were aged 3 days (conventional ageing) or 15 days (prolonged ageing) and pork cuboids were cooked at 50–80°C for 30 min. Cooking loss, total water content (TWC), Warner–Bratzler shear force (WBSF) and shrinkage (longitudinal, transverse and estimated volume) of the pork loin cuboids were measured. Key results: Prolonged ageing for 15 days reduced the WBSF of samples cooked at 50°C, and the cooking loss for samples cooked at 70°C and 80°C, relative to conventional ageing for 3 days. The WBSF of pork aged for 15 days was not different from that of pork aged for 3 days. Prolonged ageing reduced longitudinal shrinkage of cuboids, but TWC and transverse/volume shrinkage of cuboids were not affected by ageing. The diameter of cooked muscle fibre fragments was smaller in pork subjected to prolonged ageing. Conclusions: Prolonged ageing was favourable for minimising cooking loss at higher cooking temperatures but was only favourable for tenderness at the lowest cooking temperature. Low pH of the samples is likely to have caused the lack of tenderisation with ageing. This study aimed to characterise the effect of prolonged ageing and cooking on pork-quality traits.

The objectives of this work was to study the effect of sex and weight at slaughter on meat quality in the longissimus muscle of Black goat and Meriz goat. Twenty four weaned kids from each breed were divided equally and penned individually into two groups. The 1st was castrated using rubber ring, and the 2nd was left intact, and was assigned to be slaughtered at 15,20 and 25 kg live body weight.The overall means of pH, lightness, redness, yellowness, drip loss, cooking loss and tenderness were 5.94±0.009, 46±1.16, 20.01±0.68, 35.68±0.78, 0.25±0.01, 12.17±0.35, 1.65 ±0.008, respectively. Results revealed neither breed nor sex had a significant effect (p>0.05) on pH, color, drip loss, cooking loss and tenderness. It seems that kids slaughtered at 15 kg had more lightness, have more drip loss, and lower cooking loss as compared with kids slaughtered at 20 and 25 kg. [ABSTRACT FROM AUTHOR]

This work investigated the improvement of amylopectin addition on the quality of myofibrillar proteins (MP) gel damaged by high doses of epigallocatechin-3-gallate (EGCG, 80 μM/g protein). The results found that the addition of amylopectin partially alleviated the unfolding of MP induced by oxidation and EGCG, and enhanced the structural stability of MP. Amylopectin blocked the loss of the free amine group and thiol group, and increased the solubility of MP from 7.0% to 9.5%. The carbonyl analysis demonstrated that amylopectin addition did not weaken the antioxidative capacity of EGCG. It was worth noting that amylopectin significantly improved the gel properties of MP treated with a high dose of EGCG. The cooking loss was reduced from 51.2% to 35.5%, and the gel strength was reduced from 0.41 N to 0.29 N after adding high concentrations of amylopectin (A:E(8:1)). This was due to that amylopectin filled the network of MP gel after absorbing water and changed into a swelling state, and partially reduced interactions between EGCG and oxidized MP. This study indicated that amylopectin could be used to increase the polyphenol loads to provide a more lasting antioxidant effect for meat products and improve the deterioration of gel quality caused by oxidation and high doses of EGCG.

The aim of the study was to determine changes in water-holding and water-binding capacities in relation to the tenderness of fallow deer semimembranosus (SM) and longissimus thoracis et lumborum (LTL) muscles during ageing. In the study, muscles obtained from 18-month-old farm-raised fallow deer bucks were used. The quality of the meat was determined during ageing for 48 h, 168 h, and 288 h post slaughter. It was noted that ageing had a negative effect on water retention in fallow deer meat. It decreased the ability of meat tissue to bind added water (p < 0.01) and increased cooking losses (p < 0.01), though it also increased tenderness (p < 0.01). Generally, SM showed lower (p < 0.001) tenderness than LTL. SM and LTL muscles were similar in terms of free water content, ability to bind added water, and cooking losses (p > 0.05). The way the meat was heated (cooked in water vs. roasted in the dry air) affected only cooking losses (p < 0.05), which were higher in roasted samples but had no effect either on volume loss or meat tenderness. In conclusion, the main factor affecting the water holding and binding capacities, as well as fallow deer meat tenderness, is ageing. The time enough to obtain tender meat is 168 h for LTL, whereas SM should be aged for 288 h. [ABSTRACT FROM AUTHOR]

The objective of the current study was to optimize the cook-chill conditions of high-value whiteleg shrimp (Litopenaeus vannamei) processed using the sous vide (SV) technique and to assess the effects of various time-temperature combinations on the physicochemical, textural, and sensory qualities. For optimization, a Response Surface Methodology (RSM) approach utilizing a Central Composite Design (CCD) was adopted. Optimum SV cooking conditions to acquire minimum texture (hardness) of 7235 g was 13.48 min and 81.87 °C, expressible moisture of 18.48% was 14.5 min and 84.5 °C, and cook loss of 5.58% was 5 min and 75 °C. Texture (hardness) and expressible moisture decreased while cooking loss increased with increasing time-temperature treatment. Redness and yellowness values increased (p

Wet-aging (WA) and dry-aging (DA) methods are usually used in the beef industry to satisfy the consumers' tastes; however, these methods are not suitable for all anatomical cuts. In this study, WA and DA were applied to improve the quality of two cuts of Charolais beef (Longissimus dorsi and Semitendinosus). For 60 days (i.e., 2 days, 15 days, 30 days and 60 days of sampling), a physicochemical, rheological, and microbiological analysis were performed at WA (vacuum packed; temperature of 4 ± 1 °C) and at DA (air velocity of 0.5 m/s; temperature of 1 ± 1 °C; relative humidity of 78 ± 10%) conditions. The results showed that the aging method influenced the aging loss (higher in the DA), cooking loss (higher in the WA), malondialdehyde concentration (higher in the DA) and fatty acid profile (few changes). No differences in the drip loss and color were observed, which decreased after 30 days of aging. The WBSF and TPA test values changed with increasing an aging time showing that the aging improved the tenderness of meat regardless of the aging method. Moreover, the aging method does not influence the microbiological profile. In conclusion, both WA and DA enhanced the quality of the different beef cuts, suggesting that an optimal method-time and aging combination could be pursued to reach the consumers' preferences.

Heterocyclic aromatic amines (HAAs) are mutagenic/carcinogenic compounds that can be formed during the cooking process of proteinaceous foods such as meat. Therefore, it is needed to inhibit or reduce their formations in cooked meats. Hereby, the effects of sumac usage (0.5%, w/w) in beef meatball preparation on the formation of HAAs and some quality parameters (water, pH, cooking loss, and lipid oxidation values) of meatballs cooked at 150 and 250 °C were investigated. The sumac usage caused a reduction in pH (p < 0.01), cooking loss (p < 0.05), lipid oxidation level (TBARS, p < 0.01), and total HAA amount (p < 0.05) of the samples. In addition, increasing the cooking temperature significantly decreased the pH value (p < 0.01) and increased the cooking loss (p < 0.05) of the samples. Only one compound, 2-amino-3,8-dimethylimidazo [4,5-ƒ]quinoxaline (MeIQx), from nine different HAAs studied in this study, could be determined, and the levels of the other HAAs studied were lower than their detection limits. On the other hand, MeIQx was not detected in the samples cooked at 150 °C, it was only determined in the control group samples cooked at 250 °C. The sumac usage completely inhibited MeIQx formation in the samples. Due to its positive effect on cooking loss value, lipid oxidation level, and MeIQx formation, it can be suggested to use sumac powder in meatball preparation. [ABSTRACT FROM AUTHOR]

To maximise tenderness, minimise cooking loss, and decrease the adverse effects on the colour of beef short ribs, third-order multiple regression models were used to optimise the processing parameters during the pulsed electric fields (PEF) followed by sous vide (SV) processing. Electric field strength (EFS) and specific energy (SE) of PEF ranged from 0 to 0.85 kV/cm and 0 to 110.96 kJ/kg, respectively, and SV processing for 12, 24, or 36 h at 60 °C was applied. The optimum PEF-SV processing conditions for short ribs were found at EFS of 0.85 kV/cm and SE of 110.96 kJ/kg with SV processing at 60 °C for 23.96 h. In the absence of PEF pre-treatment, the optimum SV time at 60 °C was 36 h. PEF pre-treatments (SE, 99–110.96 kJ/kg) followed by SV (24 h) at 60 °C resulted in a significantly lower cooking loss (%) and texture profile analysis hardness compared to PEF at all treatment intensities, followed by SV at 60 °C for 36 h. Furthermore, significant differences were not observed in the redness, hue angle, and chroma at different PEF-SV processing parameters. Therefore, for industrial applications, PEF-SV processing with EFS (0.85 kV/cm), pulse width (20 µS), pulse frequency (50 Hz) and SE (110.96 kJ/kg), and SV temperature–time combination of 60 °C and 23.96 h is highly recommended.

This study aimed to nutritionally and technologically characterize the meat produced by rabbit (Oryctolagus cuniculus, Flemish Giant breed, 50 farmed individuals) and hare (Lepus europaeus Pallas, 50 hunted individuals). Muscles were sampled from several carcass regions: dorsal torso—Longissimus dorsi (LD), thigh—Semimembranosus (SM), and upper arm—Triceps brachii (TB). To better depict the meat's nutritional quality, the proximate composition and fatty acid profile were assessed, and then gross energy content and lipid sanogenic indices (Polyunsaturation—PI, atherogenic—AI, thrombogenic—TI, hypocholersyerolemic/hypercholesterolemic ratio—h/H, Nutritional Value Index—NVI) were calculated. pH values at 24 and 48 h post-slaughter, cooking loss (CL), and water-holding capacity (WHC) were the investigated technological quality traits. Gross energy was higher in rabbit TB samples, compared with hare, due to more accumulated lipids (p < 0.001). pH value was higher for TB muscles in both species; the WHC was higher for hare (p < 0.001), and CL was higher for rabbit (p < 0.001). The PI values were 6.72 in hare and 4.59 in rabbit, AI reached 0.78 in hare and 0.73 in rabbit, TI was calculated at 0.66 in hare and 0.39 in rabbit, and the h/H ratio reached 3.57 in hare and 1.97 in rabbit, while the NVI was 1.48 in hare and 1.34 in rabbit samples. Meat from both species is nutritionally valuable for human consumers, meeting nutritional values better than the meat of farmed or other wild species of fowl and mammals. Hare meat was found to be healthier than rabbit in terms of lower fat content, lighter energy, and better lipid health indices. [ABSTRACT FROM AUTHOR]

Meat mimics were prepared from pea protein isolate-alginate gel via 3D printing. The texture of 3D-printed meat mimics was modified by incorporating transglutaminase (TGase) or κ-carrageenan (κc) at 0.3, 0.6 or 0.9% (w/w) into printing material prior to 3D printing. Rheological properties of modified printing material were measured; results were used to support 3D printing results. Textural properties of raw and cooked meat mimics were determined and compared with those of selected animal meats, namely, pork tenderloin, chicken breast, salmon meat and Spanish mackerel. Cooking losses of meat mimics were also determined. G′, G″ and tan δ of TGase-modified material were not significantly different from those of the control. In contrast, increasing κc content resulted in increased G′ and G″; tan δ of all κc-modified samples decreased from that of the control. Addition of TGase at 0.9% into printing material increased the hardness of raw meat mimics, while κc at 0.9% increased hardness of cooked meat mimics. Raw meat mimics treated with 0.9% TGase exhibited texture closest to raw salmon. Texture of cooked meat mimics treated with 0.9% κc was closest to that of cooked salmon. TGase-treated meat mimics tended to experience lower cooking losses, while κc-treated meat mimics exhibited an opposite trend. [ABSTRACT FROM AUTHOR]

Summary: Raspberry pomace, the main by‐product of the raspberry juice extraction process, consists mainly of raspberry peels and seeds, rich in polyphenols and fibres. The recovery of this waste by drying and fine grinding gives a powder suitable for many applications. This study aimed to assess the technical quality, functional properties, and consumer acceptability of five pasta samples produced by replacing durum wheat semolina (Triticum durum) with 3.70%, 5.61%, 7.69%, 9.88%, and 12.00% raspberry powder. The control sample was 100% hard semolina pasta. The cooked pasta (RP) with 7.69% raspberry powder replacement showed higher acceptability values, a slight decrease in hardness, compactness, and time of optimal cooking (OCT) than the control semolina pasta (CP). Furthermore, the "half of the maximum inhibitory concentration" (IC50), evaluated through the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) and 2,2'‐Azino‐bis(3‐ethylbenzothiazoline‐6‐sulphonic) acid (ABTS) tests, showed an increase of about twice the antioxidant activity compared to the semolina paste, both before and after cooking.

This experiment was conducted to evaluate the effects of ambient temperature and coriander seed supplementations on meat quality of Sasso T44 and Koekoek. Both breeds were exposed to two temperature rooms with a heated room of 32 ± 1.2 °C from 11:00 am to 16:00 pm and the normal room temperature of average maximum and minimum of 23.8 ± 3 °C and 16.6 ± 1.6 °C, respectively, with a relative humidity between 34.5 ± 4 and 44.8 ± 3%. Both breeds were also further randomly allocated to three levels of 0 g/kg, 5 g/kg and 10 g/kg coriander seed powder supplementations. The experiment was conducted from 9 to 20 weeks of age. There was a slight variation in breast lightness (L*; P < 0.05) due to temperature at 48 h after slaughtered. At 48 h after slaughtered, breast from cockerels reared in a heated room became slightly lighter compared to groups reared at normal temperature. However, the overall meat colour did not categorized under the paled colour of meat; rather, it can be in the darker than normal category. Moreover, breast of Koekoek at 1 h after slaughtered was more yellow (P < 0.05) in colour and higher chroma values, while at 48 h, Sasso T44 had redder meat (P < 0.05) than Koekoek. In addition, the thigh meat of Koekoek had more total ash than Sasso T44 (P < 0.05). However, Sasso T44 breast had better water holding capacity due to lower in drip loss percentage (P < 0.05) than Koekoek. This research indicated that some meat quality variations were shown between breeds, while temperature had no effect on the meat quality parameters conducted except the L* value at 48 h, which was higher in groups of cockerels placed in a heated room. However, further insights into other physical meat qualities and sensory evaluations may also reveal to the meat quality of these breeds. [ABSTRACT FROM AUTHOR]

A study was conducted to determine the effect of probiotics and thyme essential oil (TEO) as feed additives on the sensory attributes, cooking loss and the texture of broiler chicken meat. Day-old broilers Ross 308 (n=400 chicks) were randomly divided into four groups based on the feed supplement as follows: C-control, E1-probiotics 0.05%, E2-TEO 0.05% and E4-combined, probiotics 5% with TEO 5%, respectively. The fattening period was 42 days. Warner Bratzler shear force, cooking loss and the following sensory attributes (colour, odour, taste, texture, meat decomposing and overall acceptability) were tested. The obtained results of the Warner Bratzler shear force show that there was significant different (p

The current study investigates the effect of ultrasound-assisted cooking on broiler meat quality. The objective of this study was to explore the combined effect of ultrasound treatment (US) (40 kHz, 120 Wcm−2) at different cooking temperatures (50, 60, 70, 80 °C) on physicochemical and sensory attributes of broiler meat. Therefore, pH, cooking loss %, Thio-barbituric acid reactive substances (TBARS), shear force, color, and sensory properties were investigated and compared with the control group. The result showed that the ultrasound treatment had no significant effect on pH values compared to the control group. The cooking loss % decreased with the application of US treatment at higher temperatures, which implied a higher cooking yield. Furthermore, sonicated meat showed lower shear force values even at 80 °C cooking temperature, which indicates increased tenderness. In addition, lower TBARS values were recorded at 50 °C temperature in combination with ultrasound, but the other treatments were similar to the control group. The application of ultrasound increased the lightness of meat with a significant decrease in lightness and yellowness. Meat cooked at 80 °C with US showed a significantly higher sensory score (odor, flavor, tenderness, juiciness, overall acceptability) than other treatment groups. The treatment of ultrasound combined with temperature was considered a promising and efficient technique for processing as it increased the perception of tenderness with less cooking losses and higher sensory attributes.

One experiment was carried out to investigate the effect of low crude protein (CP) diets supplemented with crystalline essential amino acids (EAAs) on growth performance, meat quality, and nitrogen retention in Japanese quails reared from 1 to 35 days of age. A total of 840 unsexed one-day-old quail chicks were used in a completely randomized design consisting of seven treatments with six replicates and 20 birds in each. In addition to the control diet, two negative control diets were also adjusted to contain 10 and 20% lower CP than the control (LP10 and LP20 diets, respectively). The EAAs/CP ratio was similar to that of the control diet. Also, four rations supplemented with amino acids were formulated to contain 10% (LP10+EAAs10 and LP20+EAAs10) or 20% (LP10+EAAs20 and LP20+EAAs20) higher EAAs than LP10 and LP20. Crude protein digestibility was determined using the total collection method at 21 and 35 d of age. After slaughtering at 21 and 35 d of age, whole-breast meats were dissected out to determine meat quality indices. During 1 - 21d of age, 10 or 20% reduction in CP significantly decreased body weight gain and increased feed conversion ratio; however, amino acid supplementation significantly improved body weight gain and feed conversion ratio (P < 0.05). During 1- 35 d of age, reduction of CP to 20% led to decreased body weight gain in EAAs supplemented and un-supplemented diets. Dietary treatments did not have any significant effect on the breast meat quality variables except for pH. At 35d of age, 20% reduction in dietary CP significantly reduced nitrogen retention percentage. Overall, a 10% reduction in dietary CP without EAAs supplementation had no adverse effect on the growth performance of Japanese quails during the 1 to 35d of age.

This study was conducted to evaluate the effect of adding eggshell membrane (ESM), a by-product of the chicken egg processing industry, to emulsified meat models with different NaCl concentrations. The aim was to examine if ESM could facilitate a reduction in the amount of NaCl added to this type of product. The effects of ESM addition were investigated in terms of cooking loss, water distribution, color, and texture properties using a simplified meat emulsion model with no other additives than ESM. Emulsified meat samples were made with three different NaCl concentrations (0.5, 0.1, 1.5% w/w), without and with three levels of ESM (0.5, 1.0, 1.5% w/w). Addition of ESM reduced cooking loss (CL), improved texture, and increased redness. Effects of ESM were explained by structural changes in the protein matrix, as shown by two different histological methods. The addition of ESM explained 86% of the variation in low-field Nuclear Magnetic Resonance (LF-NMR) T2 relaxation times in uncooked samples, while 97% of the variation in cooked samples was explained by the NaCl concentration. Fourier transform Infrared (FTIR) micro-spectroscopic measurements revealed that samples supplemented with ESM had a higher proportion of α-helical structures and reduced amount of protein ß-sheet aggregation in samples with 1.0 and 1.5% NaCl. It was shown that ESM increased the pH of the emulsified meat, and it was, therefore suggested that increased negative repulsion effects had a positive heat stabilizing effect on the protein network. The fact that the cooked samples were redder was probably related to the antioxidant effect of ESM which was measured as MDA (malondialdehyde) equivalents after in vitro digestion of the samples. ESM can thus help reduce the salt content in sausages while ESM also has a positive antioxidant effect improving color.

This study aimed to investigate the amount of thiamine in selected legumes using two different cooking techniques, pressure cooking and pan cooking, and determine thiamine bioaccessibility in cooked legumes by in vitro gastrointestinal system. Cooking loss of thiamine ranged from 1.9% to 34.5% by pressure cooking and from 9.2% to 47.1% when cooked in a pan. The losses of thiamine in legumes were low by pressure cooking. The average bioaccessibility of thiamine in legumes cooked under pressure was 81.6%, and cooked in the pan was 79.6%. Thiamine was more stable when legumes were cooked with pressure than pan cooking.

Simple Summary: Freezing is used to extend the storage time of meat and is common practice in lamb meat production, since it maintains a steady supply of seasonal meat throughout the year and allows shipping over long distances. Fresh meat may also be purchased and frozen at home, to enable longer storage of the product before consumption. Freezing is the best preservation method, apart from chilling of fresh meat. However, differences in quality parameters between fresh and frozen meat may influence consumer choice and preferences. It is thus important to evaluate these differences, and how they are affected by conditions and animal handling during primary production, slaughter method and storage conditions before retail sale. This study examined the effect of freezing on technological meat quality and sensory attributes in lamb meat samples collected at two different slaughterhouses using different slaughter methods. Several differences between fresh and frozen-thawed meat were detected in terms of technological meat quality and sensory attributes, including colour, Warner-Bratzler shear force, cooking loss, flavour attributes and juicy texture. Technological meat quality and sensory attributes of fresh and frozen lamb meat were compared. Samples were collected from two abattoirs (one small-scale, one large-scale) that use different slaughter methods in terms of chilling regime and electrical stimulation. The fresh and frozen meat samples included products from both slaughter systems. Ten twin pairs of ram lambs were used in the study, with one of each twin slaughtered at each abattoir. Fresh meat was analysed after chilling and frozen meat was stored frozen for three months and analysed after thawing. The Musculus longissimus thoracis et lumborum was analysed for colour, cooking loss, sensory attributes, Warner-Bratzler shear force (WBSF) and distribution of water and lipid within each meat sample. Meat samples analysed after frozen storage were darker, less red and more yellow than the fresh meat. Freezing and frozen storage increased fluid loss and WBSF compared with the fresh meat, due to protein denaturation. Frozen storage affected sensory attributes by increasing fatty odour, frying flavour, sour flavour, fatty flavour and liver flavour, and by reducing juicy texture and mushy texture.

In the developing world, protein-containing foods are gaining importance as healthy food. Chicken meats are low-cost protein sources worldwide and are rich in water-soluble B group vitamins. Therefore, from a nutritional point of view, primary data on the vitamin composition of these thermally processed foods are required. In our country, boiled and fried chicken meats are frequently consumed. However, there is insufficient data on the loss of vitamins in meats through cooking. This study aimed to determine the vitamin B1, B2, and B3 levels of selected chicken parts using two different cooking techniques, boiled and fried, and evaluate the cooking losses of these vitamins in chicken meat. Vitamin B1, B2, and B3 contents in each raw and cooked chicken sample were determined by the HPLC device. All chicken meats' vitamin B1, B2, and B3 content were significantly decreased after boiling and frying (p<0.05). The boiling method's average cooking loss of vitamin B1, B2, total vitamin B3, nicotinic acid, and nicotinamide in chicken meats was 53%, 43%, 31%, 58%, and 18% respectively. By frying, it was 24%, 50%, 42%, 78% and 40%, respectively. The nicotinamide content of all samples was considerably higher than nicotinic acid. The highest cooking losses were determined in nicotinic acid. [ABSTRACT FROM AUTHOR]
