Trichiutus haumela
bined with different concentrations of tea polyphenols (TP) on hairtail ( ) were studied. The
sensory score, total bacteria count, total volatile base nitrogen (TVB鄄N), pH value and the 2鄄thiobarbituric acid (TBA )
were used to evaluate the fish quality during cold storage. The results showed that the hairtail coated with chitosan and tea
polyphenols was significantly better in quality than
