Abstract In this study, composite coating solutions with different concentrations (0%, 0.3%, 0.6%, 0.9%, 1.2%, and 1.5%) of cinnamon essential oil were prepared with Auricularia auricular polysaccharides and cinnamon essential oil as basic ingredients. Fresh-cut perch fillet was treated with the coating solution and stored at 4 ℃ for up to 12 days. By measuring the drip loss rate, sensory quality, pH value, thiobarbituric acid reactive substances (TBARS) value, total volatile basic nitrogen (TVB-N) content, and total viable count of fresh-cut perch fillets during storage, the effect of cinnamon essential oil-A. auricular polysaccharide composite coating on fresh-cut perch fillets was investigated. The results showed that cinnamon essential oil-A. auricular polysaccharide composite coating delayed drip loss and the decline in sensory quality and effectively slowed down the increase in TBARS value and TVB-N content by inhibiting bacterial growth and reproduction, the effect being more pronounced with increasing concentration of cinnamon essential oil. On the 12th day of storage, the TBARS value, TVB-N content and total viable count in the 1.5% cinnamon essential oil composite coating group were 0.47 mg/kg, 18.1 mg/100 g and 5.20 (lg (CFU/g)), respectively, indicating a good effect on fillet preservation. Compared with the uncoated group, the composite coating extended the shelf life of refrigerated perch fillet by 3 days.
