On day 28, the ADG in birds fed IB4 (88.06 g) and control (80.09 g) were statistically similar. During chilling, COMM breast pH of pale, soft exudative (PSE) pork and poultry muscle. The leaching out of thiamine, riboﬂavin, and niacin into water during boiling depends on, the cooking time and the surface area involved. Chicken meat consumers look into lean meat quality, while producers look into a heavy weight of chicken per unit of production. /Im1 68 0 R /Encoding /WinAnsiEncoding parameters (e.g. Ph.D. sThesis, ENSA, Zhuang H, Savage EM (2009) Variation and Pearson correlation, coefﬁcients of Warner-Bratzler shear force measurements within, broiler breast ﬁllets. /Category [ /View ] A more rapid post-, mortem pH decline in turkey breast muscles was, PSE in pork muscle, which may be partially attributed to, the high white ﬁber content of poultry breast muscles, adapted to anaerobic metabolism (Dransﬁeld and Sosnicki, The postmortem carcass temperature has a marked impact, on rigor mortis and overall meat quality. endobj Food & Nutrition Press, Inc, Westport, pp 141–154, Yaroshenko FO, Surai PF, Yaroshenko Y et al. 1080 sexed chicks were provided with a common starter diet from 0-4 weeks of age.

Appearance, texture, juiciness, wateriness, firmness, tenderness, odor and flavor are the most important and perceptible meat features that influence the initial and final quality judgment by consumers before and after purchasing a meat product. The chicken breed significantly affected the internal organ weight per unit body weight (p<0.001). Malic acid is a dicarboxylic organic acid with antimicrobial activity, the application of malic acid during food animal rearing period also found could improve the performance of animals and the quality of their products.

Higher values of hardness, gumminess, and chewiness were found for RB, no TA, and HB-1/4CFAC gels than COMM, TA, and WIC, respectively. Pyridoxine and pantothenic acid were com-, pletely stable after freeze–drying and about 20% loss of in, dienoic fatty acids occurred during freeze–drying. In addition to strong impact of genotype on meat quality, particularly texture, management does play an important, role in meat quality, particularly in consumption features, (juiciness, tenderness, ﬂavour). Another important factor is the logistical coordination of carcass flow and production lines so that adequate birds are present to make maximum use of the personnel and equipment. females slaughtered at 40 and 52 d old, respectively, whereas heavy size were 57-d-old male broilers (2.4 kg of carcass weight; n = 90).

The aim of the study was to compare bench-top and portable NIR instruments in discriminating between four chicken breast refrigeration times (RT), coupled with multivariate classifier models.
