    摘要:

    以猪肉和鸭肉为原料,制作重组肉,研究魔芋胶、卡拉胶、黄原胶添加量和添加方式对重组肉持水力和水分活度的影响。结果表明:食品胶单独添加时,重组肉持水力随食品胶含量的增大而增大,相同含量的3种食品胶对重组肉持水力和水分活度的影响从大到小均为黄原胶、魔芋胶、卡拉胶;冷水分散添加、热水溶胶和干粉添加3种方式中,重组肉持水力在冷水分散添加方式下最大,在干粉添加方式下最小;食品胶复配添加时,黄原胶、魔芋胶、卡拉胶的总含量为0.7%,且黄原胶、魔芋胶、卡拉胶的质量比为3﹕1﹕3时,重组肉的持水力最大;由重组肉电镜扫描结果可见,重组肉蛋白质相互交联,形成了高分子网络凝胶,蛋白质凝胶网络的松弛程度是影响持水力的主要因素。

    Abstract:

    The duck and pork were used making restructured meat as the raw material. The influences of the amount and methods for food gum addition on water-holding capacity and water activity of restructured meat were discussed. The results showed that water-holding capacity of restructured meat increased with increasing amount of the food gums and rexanthan gum had the strongest influence on water-holding capacity and water activity, followed by konjac gum,and carrageenan. The cold-water dispersion method was superior to the aqueous colloids method and the dry powder method. The result of the orthogonal test showed that restructured meat has the best water-holding capacity when the total gum concentration was 0.7% and the compound ratio of xanthan gum, konjac gum and carrageenan was 3∶1∶3. Microstructure demonstrated that the protein cross linked and the relaxation of gel was the main influence factor.
