Abstract

This study will be developed in Laboratory of Animal Products of College Agricultural and Veterinary Sciences, UNESP, Jaboticabal. Will be used 240 muscles Pectoralis major of different categories birds (broilers and free range poultry, males and females, in ideal age for slaughter and spent birds). The muscles will be subjected to different maturation periods (0, 3 and 7 days) in BOD chamber and analyzed color, pH, water holding capacity, weight loss by cooking, shear force, myofibril fragmentation index, sarcomere length, collagen, chemical composition, cholesterol and fatty acid profile. Will be made hamburgers with meat to broilers and free range poultry in ideal age for slaughter and spent birds. The formulations which will vary depending on the proportion of breast (B) meat and thigh + drumstick (T+D) (50B:50T+D; 60B:40T+D; 40B:60T+D). Will be stored frozen (-20°C) to 7, 15 and 30 days to analyze lipid oxidation, water activity and sensorial analysis with untrained person. To evaluate the Pectoralis major muscle quality will be used a completely randomized design (CRD) in 4x2x3 factorial design (four categories, two ages and three maturation periods) done in 10 repetitions. To evaluate the hamburgers quality will be used a CRD in 4x3x4 factorial design (meat of broilers and free range poultry of two ages, three formulations and four stored periods) done in 10 repetitions. The results will be subjected to analysis of variance and regression and the means compared by Tukey's test at 5% significance level in SAS (1999). (AU)
