Lipolysis-oxidation of Jinhua ham and its correlation during traditional processing were studied by analyzing free fatty acids ( FFA), thiobarbituric acid ( TABRS), diene value and carbonyl value.

Diene value and carbonyl value were positively correlated with temperature ( R~ 2 is 0.938 8 and 0.841 6 respectively).

双烯值、羰基值与温度呈正相关（R2分别为0.9388和0.8416）。
