摘要: 研究了板鸭生产过程中各工艺点样品肌肉中酸性脂肪酶、中性脂肪酶和磷脂酶活力的变化趋势。结果显示,板鸭在腌制过程中,这三种酶呈逐渐上升的趋势,而在排坯和风干过程中,酶活性逐渐丧失。通过相关分析表明,板鸭加工过程中,盐含量及水分含量与这三种酶活性之间具有显著的相关性。

Abstract: The changes of acid and neutral lipases activity, and phospholipase activity in the muscle of dry-cured duck during processing were studied. The results showed that the activities of these three enzymes increase during the process of curing, but decrease during piling and drying. The co-relationship analyse showed that the contents of salt and water are significantly correlated to the activities of these three enzymes during processing Nanjing dry-cured duck.

Key words: dry-cured duck, acid lipases, neutral lipases, phospholipase
