To establish the quality evaluation of vinasse hairtail,the correlations between physicochemical properties and sensory qualities of vinasse hairtail were studied,then the better value of physicochemical properties were determined by principal component analysis and cluster analysis.The results showed that: there was a certain correlation between physicochemical properties and sensory qualities,such as the content of water,salt,amino nitrogen,total acid,alcohol,total sugar,protein and TBA.The quality of vinasse hairtail was good in the range of salt 3.58%~4.75%,water 46.07%~51.87%,amino nitrogen0.06%~0.08%,ethanol 2.08%~4.19%,total acid≤0.34%,TBA≤4.76.
