冻融循环对甲壳素凝聚态结构和脱乙酰反应的影响（Effects of Freezing-thawing Cyclic Treatment on Condensed State Structure and N-deacetylation of Chitin）
甲壳素 冻融循环处理 N-脱乙酰反应
2009/11/3
甲壳素和质量分数为40%的浓NaOH溶液的混合物在-18℃和40℃条件下反复进行冻融处理，结果表明慢速冷冻加低温解冻的冻融循环处理过程中，冰晶的反复形成和重结晶能够破坏甲壳素凝聚态特别是晶态结构。经过3次冻融循环处理，可使甲壳素在NaOH溶液中完全溶解，获得甲壳素最终质量分数为4%，NaOH最终质量分数约为10%的均相溶液，为用均相脱乙酰法制备半脱乙酰水溶性甲壳素提供前提。
