中文摘要: 通过油脂迁移动力学模型的建立分析油炸挂糊肉片在短时贮藏过程中油脂的迁移方式,了解油脂在传递过程中含量及传递方式的变化。进而通过相关系数法分析油脂与肉片质构特性之间的相关性,探索油脂对肉片嫩度的影响。研究结果显示,油脂在短时放置过程中的迁移方式为单一的扩散方式,7 h之后开始反向传递。油脂含量与肉片的硬度、弹性、剪切力之间具有高度正相关性,油脂的存在对肉片嫩度产生显著影响(p<0.01)。

Abstract:Based on the establishment of kinetic model of oil migration,the migration of oil in the process of short-time storage of battered and fried pork slices(BAF)was analyzed,understood the changes of oil content and transfer method.Then,the correlation between the texture characteristics of the oil and BAF was analyzed by the correlation coefficient method,and the effect of the oil on the BAF tenderness was explored.The results showed that the migration of oil in the short-term placement process was a single diffusion method,and after 7 h,it starts to reversely transfer.There was a high positive correlation between oil content and meat hardness,elasticity andbshearing force.The presence of oil had an important influence on meat tenderness(p<0.01).
