Comparative effect of edible film and coating chitosan on quality properties of Spangled emperor Lethrinus nebulosus stored in refrigerator

According to the importance of fish in the diet and the fact of being quickly spoilable, the necessity of using the new methods of packing is increasing. Interest in biodegradable coatings and films has been intensified in recent years. Chitosan is biopolymers with preservative effects and film forming ability to form antimicrobial and antioxidant coatings and films. This study, effect of film and coating prepared with chitosan solution on shelf-life Lethrinus nebulosus fillet stored in refrigerator during 12 days examined. The results was showed that total bacteria and pscychrophil counts with film (11.37 log10 cfu/g and 6.66 log10 cfu/grespectively) and coating (8.72log10 cfu/g and 6.67 log10 cfu/g respectively) significantly decreased in comparison with control sample (13.24 log10 cfu/g and 8.70 log10 cfu/g respectively) in the end of 12 days (P
