摘　　要：旨在研究对鸡蛋保鲜有效的生物保鲜剂,采用壳聚糖、蜂胶和金银花3种不同保鲜液作为保鲜剂进行试验。在25℃、相对湿度70%的贮藏条件下,对鸡蛋各项感官指标和理化指标进行测定。结果表明,壳聚糖、蜂胶和金银花保鲜液涂抹贮藏28d后鸡蛋质量损失率分别为5.42%、7.29%、6.55%,蛋黄指数分别为0.327、0.236、0.248,哈夫单位为49、45、46,气室高度为4.1、6.7、5.2mm。经比较,壳聚糖提取液效果最佳,贮藏28d后好蛋率为100%,且壳聚糖保鲜剂来源丰富,价格低廉,为天然无毒副作用的生物保鲜剂。To develop biological fresh-keeping agents, the fresh-keeping effects of preservative solu- tions made of chitosan, honeysuckle, propoli on eggs were investigated. After soaked in a solution for one minute, eggs were dried, sealed and then stored in bags at 25 ~C, with relative humidity 70~. The quality of the eggs was periodically evaluated by visual evaluation and physicochemical tests dur- ing their storage. After 28 days of storage, chitosan, honeysuckle and propoli had respectively mass losing rate of 5.42%, 7.29% and 6.55%, yolk index 0. 327, 0. 236 and 0. 248, Haugh 49, 45 and 46, and chamber diameter 4.1 mm, 6.7 mm and 5.2 mm. The result shows that Chitosan has the best fresh-keeping effect on eggs. Chitosan preservative belongs to the biological fresh-keeping agents of the abundant source, low price, and natural non-toxic side effects.
