- The chemical components of silkworm pupa crust were analyzed , and its microstructure was characterized by using scanning electron microscope . the existing realtion of among chitin 、 protein and inorganic salt in silkworm pupa crust has been observed . the results show that the major protion of silkworm pupa chitin is in pupa crust , and it accounts for about one forth of crust weight , the out surface of pupa crust is regular polygon net vein characteristics . chitin takes honeycomb shape in chitin - protein complex and conjugated with protein . the inner space of chitin - protein complex net was filled with inorganic salts . thus the theory basis was provided for working out the process route of isolation pupa chitin
對桑蠶蛹皮的成分、結構進行了化學及掃描電鏡分析，確定其含有的主要成分及含甲殼素的數(shù)量，并對其中的甲殼素、蛋白質和無機鹽三者之間的存在方式進行了觀察.研究結果表明，蛹體中的甲殼素與灰分主要含在蛹皮中，甲殼素占整個蛹體成分的2 . 71 % ，占蛹皮重量的25 . 5 % ，蛹皮外表面呈規(guī)整的多邊形網(wǎng)狀結構，蛹皮中蛋白質與蜂窩狀的甲殼素相結合，呈層狀分布，顆粒狀的無機鹽填充在甲殼素/蛋白質復合物構成的蜂窩狀的空隙中.這為制定提取蛹甲殼素的工藝路線提供了理論依據(jù)
