摘要
蚕蛹皮是蚕蛹(制丝下脚料)经人工提炼去蛹油、蛹蛋白后的废弃物,含有丰富的甲壳质。通过脱无机钙和脱色素,可得到甲壳质,再进行脱乙酰基,可得到壳聚糖。通过实验,论证了蚕蛹皮用3%的HCl脱无机盐,1.5%的KMnO4无机盐和3%的草酸漂白可得到质量较好的甲壳质。同时,在60℃的反应温度下,用浓度为40%的NaOH进行脱乙酰基,可得到工业用壳聚糖。
The silkworm chrysalis skin is a kind of waste after removing pupa oil and protein.It contains lots of chitin.It can get chitin by removing inorganic calcium, and also get chitosan through deacetyl reaction.The experiments have proved that we can obtain good chitin if the silkworm chrysalis skin soaks in HCl(3%) to remove inorganic salts,de -colored by KMnO4(1.5%) and bleached by oxalic acid.At the same time,it can get industrial chitosan by NaOH(40%) under 60℃.
