摘要: 将转谷氨酰胺酶和酪蛋白酸钠作为重组牛肉使用的黏合剂,添加量为原料牛肉质量的1.2%(m/m)。为了改善重组牛肉的品质特性,在此基础上添加魔芋粉与黄原胶复合物,通过测定重组牛肉的粘结强度、剪切力、解冻损失、蒸煮损失、色差和质构来说明食用胶对重组牛肉加工特性的影响。研究结果表明,魔芋粉与黄原胶的比例为6:4,复合食品胶添加量为0.4%(m/m)时,重组牛肉的粘结强度最好(p<0.05),生肉和熟肉的剪切力均最低,改善了肉的嫩度,使得重组肉具有最好的粘结效果。Abstract: The restructured beef was prepared by adding transglutaminase (TG) and sodium casetnate as coldbinding agent and the added quantity was 1.2% of the grossary weight.In order to improve the quality characteristics of restructured beef, konjac flour and xanthan gum were added.The binding strength, shearing force, thawing loss, cooking loss, color (L* and a*-values) and texture of restructured beef were determined.The result showed that the ratios of konjac flour and xanthan gum was 6:4, and additive amount of hybrid edible gum was 0.4% of the grossary weight could produced the highest binding strength (p<0.05) and the lowest shearing force.Meanwhile, the texture of restructured beef was improved and also possessed the best bond effect.
