摘要:

以水溶性大豆多糖为主要原料,添加无水CaCl2、甘油制得鸡蛋涂膜保鲜液,研究所成膜的透水率。结果表明,当水溶性大豆多糖浓度为6.0%、甘油浓度为3.0%、无水CaCl2浓度为1.5%时,所制得的膜透水率最低。用此配方的涂膜液对鸡蛋进行涂膜保鲜处理,室温贮藏30d后,涂膜组鸡蛋仍属A级蛋,品质优良。水溶性大豆多糖涂膜液对鸡蛋有良好的保鲜效果。

Abstract:

A fresh-keeping film for eggs was prepared with soluble soybean polysaccharides (SSPS), glycerin and anhydrous CaCl2. The film permeability rate (Pv) for water was emphatically investigated. Results revealed that the film exhibited the lowest permeability rate for water when the concentrations of SSPS, glycerin and anhydrous CaCl2 were 6.0%, 3.0% and 1.5%, respectively. The eggs coated with this film still exhibited excellent quality as an A level during storage for 30 days at room temperature. Therefore, SSPS film can provide an excellent fresh-keeping effect on eggs during storage.

Key words: soluble soybean polysaccharides, permeability rate, egg, fresh-keeping film
