【摘要】 天然丝胶蛋白质应用于化妆、保健、医药创新产品的研发,引起广泛的关注[1]。蚕茧颜色由桑叶中的胡萝卜色素和类黄酮色素决定。蚕类吃进的桑叶中含有的类黄酮色素在蚕体内由一系列的遗传基因及其结合蛋白质控制透过并运输到肠腔细胞、体液、丝腺细胞,在丝腺中分泌竹青色和绿色的丝胶蛋白质,形成竹青色和绿色蚕茧[2]。绿色茧丝的色泽多集中于蚕茧外层的丝胶[2]。我们以选配的绿色丝胶品种组合生产的全天然纯绿色丝胶蚕茧为材料,对部分绿色丝胶蛋白质功能特性功能特性的研究发现,绿色蚕丝蛋白质具有比白色丝胶蛋白质更为优异的抗氧化、抗菌、紫外线遮蔽等功能特性。更多还原

【Abstract】 Sericin protein caused widespread concern of it’s development and application on innovative products, health care, medicine makeup[1]. Cocoon’s color depends on the mulberry leaves of carotene and flavonoids pigment. When silkworm ate the mulberry leaves, flavonoid pigments which from the mulberry leaves turn into bamboo blue and green sericin protein in the silk gland by a series of genetic gene and its protein binding, and it transport to control through the intestinal cells and body fluids, finally formed bamboo blue and green cocoon [2]. Green cocoon color is mainly due to the cocoon layer sericin [3].We have to gum cocoon as experimental materials which breed from natural pure sericin green cocoon,and Study on the functional properties. We found the green silk protein compared with white sericin have better function on antioxidant, antibacterial and UV shielding.更多还原
