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
