Study on the effect of the protein from Kelp endophytes DNN6on preservation of Pseudosciaena polyactis

To research the preservation effects of protein from Kelp endophytes DNN6 on aquatic products, the Pseudosciaena polyactis was treated with 250μg /mL and 500μg /mL of protein DNN6 respectively. The sensory score, total bacteria count, total volatile base nitrogen ( TVB-N) , pH value and the 2-thiobarbituric acid ( TBA) were used to evaluate the fish quality during cold storage. Results showed that 500μg /mL protein could inhibit the increase of total bacteria count, TVB- N and TBA. The protein DNN6 can delay the corruption of Pseudosciaena polyactis, and have a good prospect in preservation of aquatic products.
