特用蚕品种天然丝胶蛋白的乳化活性研究

Study on the Emulsifying Activity of the Natural Sericin Silkworm Strain

[目的]通过品种生产来直接获得大量、优质全天然丝胶蛋白质原料。[方法]对"绿S"和"白S"2种全天然丝胶茧品种及现行推广普通蚕品种"菁松×皓月"的丝胶蛋白乳化活性进行了比较分析。[结果]试验表明,"绿S"和"白S"2个丝胶茧品种的丝胶蛋白含量极高,达95%以上,分别是对照品种茧的3.47倍和3.53倍,可以称之为全天然丝胶蛋白质;研究还表明,"绿S"品种的乳化特性也明显高于"白S"和"菁松×皓月",在保健食品领域具有更为优越的利用价值。[结论]该研究可为家蚕特用品种大量生产全天然、纯丝胶在非绢丝产业的广泛应用提供依据。

[Objective] Through variety production to directly obtain a large quantity,fine quality and natural sericin silkworm strain.[Method] Two kinds of all-natural sericin cocoon varieties ＂Green S＂ and ＂White S＂ and the current common varieties ＂Jingsong × Haoyue＂ silk emulsifying activity were comparatively analyzed.[Result] The results showed that the sericine protein of ＂Green S＂ and ＂White S＂ are very high with about 95%,and are 3.47 times and 3.53 times than that of ＂Jingsong × Haoyue＂ respectively.The results also showed that the ＂Green S＂ varieties of emulsifying activity is also significantly higher than ＂White S＂ and ＂Jingsong × Haoyue＂,in the health food industry with a much superior value in use.[Conclusion] The study will provide basis for species recovery through the production to avoid the negative and direct access to large,high-quality all-natural sericin materials.
