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。
超声波处理对小麦胚芽球蛋白理化和功能性质的影响(Effect of Ultrasound Treatment on Physicochemical and Functional Properties of Wheat Germ Globulin)
小麦胚芽球蛋白 理化性质 功能性质
2009/9/11
采用超声波处理小麦胚芽球蛋白以提高其功能性质。研究了超声波处理对小麦胚芽球蛋白理化和功能性质的影响。结果表明:经超声波处理后,小麦胚芽球蛋白的巯基和二硫键含量、紫外光谱和荧光光谱均发生了显著的变化。随着超声波功率的增加,小麦胚芽球蛋白的疏水性、起泡性、起泡稳定性、乳化性和乳化稳定性都降低;当超声波功率大于900?W时,由于小麦胚芽球蛋白重新伸展,疏水基团暴露增多,引起疏水性、起泡性、起泡稳定性、乳...
热激法修饰瑞士乳杆菌的参数优化与特性研究(Parameters Optimization and Properties for Lactobacillus helveticus by Heat-shock Treatment)
