摘要
研究了用乌贼内壳制备β-甲壳素和壳聚糖,结果乌贼内壳背木盾提取甲壳素的最佳条件为:先用1.5mol/LHCl浸24h,再用1.5mol/L NaOH于80℃浸3h,产率为3.55%。从乌贼内壳周缘提取甲壳素的最佳条件为:先用1.5mol/L HCl浸24h,再用1mol/L NaOH 75℃浸3h,产率为30.00%;产品用IR和XRD表征。致突变试验结果表明用乌贼内壳制备的β-壳聚糖无致突变性。
Isolation of β- chintin and chintosan from sepia shell had been studied and the best condition of extracting chintinfrom sepia shell (hard bone) was: soaked with 1.5mol/L HCl for 24h first, then soaked with 1.5mol/L NaOH at 80℃ for another3h. The extraction ratio was 3.55%. The best condition of extracting chintin from its soft bone was: soaded with 1.5mol/L HClfor 24h first, then soaked with 1mol/L NaOH at 75℃ for another 3h. The extraction ratio was 30.00%. Final product wascharactered by IR and XRD. The result also showed that β- chintosan was safety.
