The effects of combined application of lysozyme and resveratrol with chitosan coatings on the quality of Sciaenops ocellatus during refrigerated storage were studied. Physical and chemical indices were periodically analyzed. The chitosan composite coatings were characterized, and the mechanical properties and gas permeability were also measured. The results showed that chitosan coatings could significantly reduce the total viable count (TVC), maintain tissue hardness, chewiness and sensory quality, slow the rate of fat oxidation, and restrain the increases in pH and total volatile basic nitrogen (TVB‐N). Compared with chitosan coatings, the addition of resveratrol and lysozyme had increased the tensile strength and reduced the gas permeability. The lysozyme–resveratrol–chitosan coatings had good preservation properties. The study indicated that the 0.1% lysozyme + 0.2% resveratrol + 1% chitosan group of composite coatings could maintain the quality and extend the shelf life for 8 days compared with the control group during refrigerated storage.

壳聚糖涂层与白藜芦醇和溶菌酶的组合对冷冻贮藏过程中鞘翅目鞘翅目品质的影响

溶菌酶和白藜芦醇与脱乙酰壳多糖涂层的组合应用对尾鞘鞘cia品质的影响在冷藏期间进行了研究。定期分析理化指标。表征了壳聚糖复合涂层，并测量了机械性能和透气性。结果表明，壳聚糖涂层可以显着降低总生存率（TVC），保持组织硬度，耐嚼性和感官品质，减慢脂肪氧化速率并抑制pH值和总挥发性碱性氮（TVB-N）的增加。与壳聚糖涂料相比，白藜芦醇和溶菌酶的加入提高了抗张强度，降低了透气性。溶菌酶-白藜芦醇-壳聚糖涂层具有良好的保存性能。研究表明，溶菌酶为0.1％+ 0。
