壳聚糖-薄荷精油复合涂膜对鸡蛋保鲜效果的影响
Effect of chitosan-mentha piperita essential oil composite coating on the freshness preservation of eggs
摘要
Abstract
To extend the shelf life and maintain the quality of eggs,this study utilized a composite coating of chitosan and mentha piperita essential oil for egg preservation.By measuring the egg weight loss rate,Huff unit,yolk index,protein coefficient and pH of egg white,and supplemented by sensory evaluation,the preservation effect of the film preservation method on eggs was evaluated.Results demonstrated that the composite coating containing 2%mentha piperita essential oil and chitosan exhibited optimal preservation effects.After 20 days of storage,compared to the control group,the weight loss rate decreased by 58.49%,the Haugh unit increased by 170.31%,the yolk index improved by 125%,the protein coefficient increased by 900%,the pH fluctuation of egg white decreased by 71.15%,and the sensory evaluation score increased by 230.29%.In this case,the eggs kept better freshness and their freshness period could be extended by 8～10 d.The study provides a theoretical reference for the high quality preservation of eggs.关键词
