We examined the combined effects of prerigor and postrigor batter mixtures on protein gelation. The postrigor batter was prepared with 2% salt, whereas the prerigor meat at 5 min postmortem was used to prepare postrigor batters at different salt levels. For 5 treatments, prerigor batters were mixed with postrigor batter that had 2% salt (control) as follows: T1: ground presalted (1%) hot-boned breast with 1% salt for 50% total batch; T2: ground presalted (2%) hot-boned breast for 50% total batch; T3: ground presalted (3%) hot-boned breast for 30% total batch that was mixed with cold-boned batter for 50% total batch; T4: ground presalted (4%) hot-boned breast for 25% total batch that was mixed with cold-boned batter for 50% total batch; and T5: ground presalted (5%) hot-boned breast for 20% total batch that was mixed with cold-boned batter for 50% total batch. Treatments with both presalted prerigor and postrigor muscle showed less cooking loss and lower emulsion stability than the control, except T5. The protein solubility and apparent viscosity of the control was the lowest. Thus, presalted hot-boned muscle combined with cold-boned muscle positively affected physicochemical properties.
我们研究了宰后僵直前期和僵直后期的肉糊混合物对蛋白质凝胶化的综合影响。僵直后期肉糊用2%的盐制备,而宰后5分钟的僵直前期肉用于制备不同盐含量的僵直后期肉糊。对于5种处理,将僵直前期肉糊与含2%盐的僵直后期肉糊(对照)混合如下:T1:将预加盐(1%)的热剔骨鸡胸肉磨碎,占总批次的50%,盐含量为1%;T2:将预加盐(2%)的热剔骨鸡胸肉磨碎,占总批次的50%;T3:将预加盐(3%)的热剔骨鸡胸肉磨碎,占总批次的30%,与冷剔骨肉糊混合,占总批次的50%;T4:将预加盐(4%)的热剔骨鸡胸肉磨碎,占总批次的25%,与冷剔骨肉糊混合,占总批次的50%;T5:将预加盐(5%)的热剔骨鸡胸肉磨碎,占总批次的20%,与冷剔骨肉糊混合,占总批次的50%。除T5外,预加盐的僵直前期肌肉和僵直后期肌肉的处理组显示出比对照组更少的蒸煮损失和更低的乳化稳定性。对照组的蛋白质溶解度和表观粘度最低。因此,预加盐的热剔骨肌肉与冷剔骨肌肉相结合对物理化学性质有积极影响。
