Effects of Edible Coatings Chitosan on the Shelf Life of Large Yellow Croaker (Pseudosciaena Crocea)
摘要
Abstract
The effects of edible coatings chitosan on the shelf life of large yellow croaker (Pseudosciaena croceaduring refrigerated storage were investigated.After being killed in slurry ice,large yellow croaker were immersed in 4 ℃ chitosan(0,1%,1.5%,2%,2.5%) for 20 min,and then each sample was drained and packed in polyethylene bag and kept at 4 ℃ for 20 days.Total viable counts (TVC),pH value,total volatile base nitrogen (TVB-N),the 2-thiobarbituric acid (TBA),K-value and sensory characteristics were assessed periodically for the control and the treated groups.The results indicated that the shelf life of large yellow croaker was extended significantly at the storage of 4℃ under the chitosan treatment,and the large yellow croaker treated with 1.5% chitosan had significant preservation effects.According to analyses,we could draw a conclusion that chitosan could keep the better quality of large yellow croaker.These conclusions can provide reference for preservation and extend the shelf life of large yellow croaker.关键词
