General Appearance

Chuck is the biggest and one of the tougher cut of beef carcass. By improving the tenderness of chuck meat it can have a higher value to the consumer. The study was conducted to know the efficacy of tasty kit (containing 1.2 M sodium chloride, 0.25 M sodium bicarbonate and 0.1% ascorbic acid) as a meat preservation and tenderization technique during freezing. Beef chucks from four native bulls were collected from a local market and divided into two groups- one was treated with tasty kit and the other kept as control. Both the treated and untreated meats were well packed and kept in freezer at -20°C for a month. Compared to the untreated group, higher moisture content was found in treated raw and cooked meat (p<0.05). Significantly lower protein content (p<0.05) in treated cooked meat may be resulted from the solubilization of myofibrillar protein by salt and bicarbonate. Treated meat had a higher water-holding capacity (p<0.05), lower drip loss (p<0.05) and lower cook loss (p<0.01). During a sensory test, panellists gave significantly higher values for general appearance (p<0.01), flavour (p<0.05), colour (p<0.05), tenderness (p<0.01), juiciness (p<0.01) saltiness (p<0.01) and overall acceptability (p<0.01). It is suggested that tough chuck meat may be successfully tenderized with the salt-bicarbonate marinating technique before freezing. DOI: 10.3329/bvet.v26i1.4628 Bangl. vet. 2009.

The aim of this study was to determine the effect of probiotics on gut microbiota, on carcass and meat quality and on mineral contents in the longissimus lumborum (LL) muscle in pigs. The research was carried out with 120 hybrid pigs deriving from Naïma sows and P-76 boars. Pigs from the experimental group received the EM®Bokashi probiotic (Greendland Technologia EM®, Janowiec n/Wisłą, Poland) in their feed (containing Saccharomyces cerevisiae, Lactobacillus casei and Lactobacillus plantarum). The study showed that EM®Bokashi probiotic supplementation resulted in a significantly higher count of lactic acid bacteria (LAB) and yeasts in the feed, a lower number of Clostridium in the mucosa and colorectal digesta as well as a lower Enterobacteriaceae count in the colorectal digesta. The research showed that carcasses of the pigs who received the EM®Bokashi probiotic had a higher lean percentage and lower fat content than the carcasses of the control fatteners. Diet supplementation with the EM®Bokashi probiotic resulted in a lower pH and technological yield (TY) and a higher drip loss and shear force at a lower protein content in LL muscle. Moreover, the administration of the probiotic to fatteners resulted in higher yellowness (b*) and saturation (C*) and higher concentrations of Na, Mg and Se in meat.

ABSTRACT: This study evaluated the yield, color, and chemical composition of commercial cuts (tail, sirloin cut, back fillet, and thigh) of Pantanal caiman meat in both sexes. The yield of tail was higher than other cuts, and the yield of females (17.0%) was higher than males (15.9%). The thigh of males had lower protein content (20.8%) compared with other cuts. Females showed a higher lipid content in the tail (2.4%) and thigh (0.8%) compared with males (1.7% and 0.4%, respectively). The tail presented the greatest content of monounsaturated fatty acids (45.2%) and higher n6/n3 ratio (4.6). Although lightness was not different among cuts or between sexes, there were differences in color. Males have more yellowish meat compared with females. Thigh and back fillet were more reddish when compared to sirloin cut and tail, regardless of sex. In conclusion, female tail meat provided greater yield and lipid content than males, and this result was statistically significant. These findings can help producers and consumers alike, better understand yield, quality, and nutritional quality of Pantanal caiman meat.

AbstractThe meat palatability, water-holding capacity, colour and shear force values of 32 Boer goat (BG) kids and 32 South African Mutton Merino (MM) lambs were investigated. Two pelleted diets (offered to 16 animals per species) with either a low (LE, 9·9 MJ/kg dry matter (DM)) or a high (HE, 12·1 MJ/kg DM) metabolizable energy level were given to the animals for either 28 or 56 days. Thereafter the animals were slaughtered, the meat cooked and presented to a trained sensory panel. Organoleptically, a difference between goat and lamb was noted. Each one had a specific species flavour, which was not influenced by energy level of the diet. BG meat was perceived to be stringier than that of the MM, but there was no significant difference in Warner-Bratzler shear force values. Tenderness declined with age in both species and there was also a tendency for goat meat to be less juicy than lamb. Chevon had a more pronounced after-taste than lamb. No objective difference could be distinguished between the colour of the cooked goat and lamb, but there was a tendency for fresh lamb to have a higher a*-value (redness) than goat. Although diet did not influence drip loss, drip loss increased with an increase in slaughter age. Only after 56 days did the m. semimembranosus of MM have a significantly higher drip loss than that of BG (LE: 4·84 v. 3·43%; HE: 4·72 v. 3·23%). In the m. semimembranosus of both species cooking loss increased with an increase in slaughter age. It can be concluded that goat meat compares favourably with lamb in terms of water-holding capacity, colour and shear force values. If goats are finished in the feedlot, it can be done on a LE diet, since diet does not influences any of the mentioned characteristics. This may render a direct economic advantage for BG feedlot finishing.

Broiler chickens (Gallus gallus domesticus) were collected from local chicken suppliers of Dharan (26.8065° N, 87.2846° E), Nepal, and slaughtered to prepare the cut-up parts (breast, drumstick, dorso, wings, and thigh). They were vacuum packed in polythene bags and frozen stored (-21.5 ±3.5ºC) for 45 days to study the effect of frozen storage on the water holding capacity (WHC) of meat. Cooking loss, drip loss, and pH changes were analyzed at 5 days intervals during storage and the data were analyzed using Genstat® v 12.1.The cut-up parts showed a significant change (p<0.05) in pH, cooking loss, and drip loss during 45 days of frozen storage. The pH decreased while the drip loss and the cooking loss increased gradually upon storage. The pH was found to be varied among the cut-up parts with a minimum pH scale of 5.25 for wings, followed by 5.3 for thigh, at the end. The highest drip loss of 6.11% was observed in wings after 5 days of storage which ended up to 8.97% after 45 days of frozen storage while drumstick and thigh samples showed significantly lower drip loss of 6.02%, and 5.43% respectively. The change in cooking loss showed a similar pattern as that of drip loss with a significantly higher value of 37.36% in the breast while it showed no significant difference in drumstick, dorso, and thigh meat. Thus, the study reveals that freezing of broiler chicken meats for a prolonged period adversely affects the WHC of meat

Chickpea (Cicer arietinim) husk was extracted by non-alkaline aqueous extraction process. The residual extracted husk was dried in a cabinet drier and finally ground. Both fresh husk and processed husk were analyzed for their composition. The processed husk (extracted ground husk) was incorporated into formulations of cracker biscuits at 0- 20% replacement levels of wheat flour and baking functionalities were evaluated. The studies on the effects of processed husk on biscuit’s qualities showed that the highest spread ratio of biscuits was achieved with 3% processed husk. Analysis of cracker biscuits containing various percentage of processed husk showed that biscuits with increasing level of processed husk had higher ash, fat, moisture and crude fiber content, while lower protein and total carbohydrate content. The amount of crude fiber content of biscuits significantly increased with the incorporation of processed husk when compared with conventional biscuits. The cracker biscuits containing various percentages of processed husks were evaluated for their sensory attributes. The results revealed that cracker biscuits containing 5% processed husk secured the highest score for overall acceptability among other substitution levels.

Acute heat stress (AHS) modifies the structure of myofibrils affecting functional properties of meat, mainly the water holding capacity. This experiment aimed to identify changes in proteolysis and migration between the myofibrillar and sarcoplasmatic fractions due to pre-slaughter AHS. Myofibrillar fragmentation index (MFI), SDS-PAGE, western blot of vinculin (WB) and shear force (SF) were determined. Six hundred broilers (Gallus gallus) were slaughtered in three different days (ST). In each ST, groups of ten animals were placed in transport crates and submitted to AHS (35ºC, 75 - 85% RH) for 2 hours. Simultaneously, the non-stressed broilers (NS) were kept in thermoneutral environment (22ºC, 83 ± 6.6% RH) within the crates in the same density. After slaughter, the breast muscles were kept refrigerated until the withdrawal of all samples (0, 1, 2, 6 and 24 hours after slaughter). Sampling within AHS and NS birds was collected according to lightness value (normal L* < 49, and high > 51), except for determination of MFI and SF. The lightness was used later to perform SDS-PAGE and WB analyses. MFI kinetics showed that the fragmentation rate was superior in animals NS, indicating that AHS can harm proteolysis and rate of myofibrillar fragmentation. However, the extent of fragmentation did not change, as well as SF values. SDS-PAGE for Troponin fragments indicated a differentiated pattern between AHS and NS. The WB did not show alterations in vinculin fragmentation. Modifications in sarcoplasmatic fraction are observed in meat with high L*values, independent of environmental condition.

The aim of the study was to analyse the effect of sex, storage time and muscle type (m. longissimus dorsi and m. biceps femoris) on quality traits of the meat of French Lop rabbits. The muscles were obtained from 12 males and 12 females slaughtered at the age of 90 days. The characteristics analysed included pH, colour parameters, water holding capacity and proximate composition. No effect of sex or muscle type was found (P>0.05) on the pH of the meat in any of the periods analysed. The storage time differentiated (P≤0.01) between pH45min and pH24h and between pH45min and pH7days. None of the colour parameters was influenced by sex (P>0.05), but they were significantly affected by storage time (P≤0.01). Redness and yellowness were also influenced by the type of muscle (P≤0.01). The rabbit meat stored for 7 days was characterised by higher drip loss than the meat stored for 24 hours (1.31-1.49% vs. 3.34-3.57%, P≤0.05). The m. biceps femoris of both sexes had a greater capacity to hold water as measured by the pressure method than m. longissimus dorsi (P≤0.01). There was no effect of sex or muscle type (P>0.05) on the level of cooking loss. Sex and muscle type also had no influence (P>0.05) on the proximate composition of French Lop meat.

This study was performed to analyze the difference between the meat properties classified into 5 ranges depending on Berkshire meat quality traits. Post-mortem pH24hr was positively correlated with water holding capacity, but negatively correlated with meat color, protein content, drip loss, and cooking loss. Berkshire gilt was discovered by higher population of RFN (reddish pink, firm, non-exudative), a normal meat class when compared to barrow, whereas DFD (dark, firm, and dry) was not detected and PSE (pale, soft and floppy, exudative) and RSE (reddish pink, soft and floppy, exudative) were found by a low number of individuals. It was assumed that Berkshire gilt is less susceptible to stress when compared with barrow. Therefore, from the results of this study, we suggest that Berkshire gilt is high possibility for production of good meat due to a forming ability for better meat quality than that of Berkshire barrow.
