摘要:

本实验对胭脂虫(Dactylopius coccus Costa)色素加工剩余物进行甲壳素提取。结果表明,蛋白质脱除最适条件为NaOH 浓度1.0mol/L,反应温度80℃,时间2h;无机盐脱除最适条件为盐酸浓度1.0mol/L,反应温度50℃,时间60min。

关键词: 胭脂虫, 甲壳素, 蛋白质, 无机盐

Abstract:

The technology for the chitin extraction from the residue of Dactylopius coccus Costa cochineal dye process was studied. The results showed that the optimal conditions for protein removal are 1.0 mol/L NaOH at 80 ℃ for 2 h, and those for inorganic salt removal are 1.0 mol/L HCl at 50 ℃ for 60 min.

Key words: cochineal, chitin, protein, inorganic salt
