Tracking sampling was done in yeast culture and in mechanized big pot fermentation of yellow rice wine. Then the samples were ana-lyzed by AccQ·Tag derivation method coupled with HPLC,and the dissociative amino acids were detected. The results showed that amino acid is one of the important factors influencing yeast culture. The change rules of amino acid content in machanized production of yellow rice wine were investigated and amino acid content of yellow rice wine produced by different wheat starter were ...
