摘要
研究对鸡蛋保鲜有效的中草药提取液。采用银杏叶、金银花、蒲公英和肉桂皮4种植物的乙醇提取液作为保鲜剂,对鸡蛋进行涂膜保鲜实验。在温度25℃、相对湿度50%～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,结果显示各处理组均具有一定的保鲜效果。其中以金银花提取液的效果最佳,贮藏35d后好蛋率为100%,其失重率为2.67%,蛋黄指数为0.358,浓蛋白含量为55.65%,哈夫单位(HU)为50.247,气室高度为2.13mm。
To develop natural herbal antistaling agents,the fresh-keeping effects of separate ethanol extracts of Ginkgo biloba L.,Lonicera maackii [Rupr.] Herder（honeysuckle）,Taraxacum mongolicum and Cinnamomum cassia Presl on eggs were investigated.Eggs were immersed in the above extracts for 5 min,dried,sealed in bags and stored at 25 ℃ and relative humidity 50%-70%.The quality of the eggs was periodically evaluated by sensory evaluation and the determination of some physicochemical indexes during storage.The results showed that honeysuckle extract had the best fresh-keeping effect and the percentage of fresh egg was 100% after 35 days of storage,with weight losing rate 2.67%,yolk index 0.358,the content of dense albumen 55.65%,Haugh unit 50.247,and the height of air chamber 2.13 mm.
