Abstract:

Changes in contents of total acid, reducing sugar, nonvolatile acids and amino acid nitrogen were continuously analyzed during processing of Zhenjiang fragrance vinegar. These changes were then subjected to the dynamic analysis to find the relationships between physicochemical indexes and aroma components by combining changes of aroma components. Results indicated that the changes in the contents of total acid, reducing sugar, nonvolatile acids and amino acid nitrogen differ during the whole production process, meanwhile there are close relationships between the changes of physiochemical indexes and aroma components in different production processes.

Key words: Zhenjiang fragrance vinegar, physicochemical index, aroma components
