苦豆子多糖与中草药复合膜贮藏鸡蛋

Study on Storage of Eggs with Compound Coating Film of Sophora alopecuroides Polysaccharides and Chinese Medicinal Herb

以苦豆子多糖为成膜基质,添加适量的CaCl2和柠檬酸为增塑剂,以甘油为成膜助剂,添加中草药大黄与黄连提取成分制备可食性复合膜.研究了常温（温度25 ～28℃,相对湿度60％～75％）下该复合涂膜保鲜剂对鸡蛋品质及其生理生化变化的影响.结果表明：涂膜贮藏30 d后三种膜对鸡蛋的失重率、相对密度、哈夫单位、蛋黄指数、pH值和TVB-N等指标相比都优于对照组实验,从而延长了其货架期,其中配方4涂膜处理保鲜贮藏效果最佳.

Study on eggs storage effects of compound coating antistaling agent of polysaccharide.at room temperature （25～28 ℃） and relative humidity （60％～75％） were investigated.The antistaling agent was composed of Sophoraalopecuroides bean polysaccharide for the coating matrix,glycerin and Chinese herbal medicine Coptis chinensis Franch and Rheum palmatum extract was added to improve the film flexibility CaCl2 and citric acid as film-forming additives.The results showed that after 30 days＇ of storage,compared with the control group at room temperature,By determining such indexes as the rate of weight loss of eggs,the relative density,Hough unit,egg yolk index,pH value of egg and TVB-N value than in the control group,the shelf life was extended.and the best freshkeeping and storage effect comes from the treatment by using the coating Prescription 4.
