摘　　要：为研究复合植物精油涂膜剂对鸡蛋保鲜效果的影响,选取新鲜鸡蛋120枚,随机分为室温对照组、室温涂膜组、高温对照组、高温涂膜组,每组30枚,每隔10 d从各组取出5枚鸡蛋测定贮藏过程中的感官指标、失重率、哈夫单位、浓稀蛋白比例、蛋黄指数、p H值和菌落总数等指标的变化。结果表明:鸡蛋经过复合植物精油涂膜剂处理后,显著减少了鸡蛋的散黄率、失重率和蛋清菌落数,提高了鸡蛋的感官指标、蛋黄指数、哈夫单位、浓稀蛋白比例,减缓p H值的剧烈变化;鸡蛋新鲜度顺序是室温涂膜组>高温涂膜组>室温对照组>高温对照组。结论:鸡蛋经复合植物精油涂膜剂处理后,显著改善了鸡蛋品质的评价指标,复合植物精油涂膜剂具有较好的保鲜效果,可以显著延长鲜蛋的保质时间。In order to study the effect of compound plant essential oil coating agent on egg preservation,120 fresh eggs were selected and randomly divided into room temperature control group,room temperature coating group,high temperature control group and high temperature coating group,with 30 eggs in each group.Five eggs were taken from each group every 10 days to measure the changes of sensory indexes,weight loss rate,Huff unit value,ratio of thick protein to thin protein,yolk index,pH and total number of colonies during storage.The results showed that after the eggs were treated with the compound plant essential oil coating agent,the yolk dispersion rate,weight loss rate and the number of colonies in egg white were significantly reduced,the sensory indexes,yolk index,Huff unit value and the ratio of thick protein to thin protein of the eggs were improved,and the drastic change of pH value was slowed down;The order of egg freshness was room temperature coating group>high temperature coating group>room temperature control group>high temperature control group.Conclusion:The evaluation index of egg quality was significantly improved after the eggs were treated with compound plant essential oil coating agent.The compound plant essential oil coating agent had a good fresh-keeping effect and could significantly prolong the shelf life of fresh eggs.
