红毛五加多糖蛋白酶-反胶束法脱色脱蛋白方法的建立与优化
Establishment and Optimization of Proteinase-Reverse Micelle Method for Decolorization and Deproteinization of Acanthopanax giraldii Harms Polysaccharide
文章探讨了蛋白酶法与反胶束法联合应用于红毛五加粗多糖的脱色和脱蛋白工艺。通过单因素实验,确定了CTAB浓度、pH值以及多糖溶液与反胶束体积比为主要影响因素。基于这些因素,采用响应面法进行了工艺条件的优化,评价指标包括脱蛋白率、脱色率、多糖回收率以及三者的加权综合评分。优化后的工艺条件如下:首先,将粗多糖溶液的pH值调至6.5,随后按照1.2×104 U/mL的浓度加入木瓜蛋白酶,并在40 ℃下酶解1.5 h。酶解完成后,再次调整多糖溶液的pH值至4.0,并加入NaCl至0.4 mol/L。然后,按照4∶1的体积比加入反胶束溶液 (正己醇、异辛烷、H2O体积比为5∶65∶30,含CTAB 0.12 mol/L),振荡5 min后离心收集水相。在优化后的工艺条件下,脱蛋白率高达84.71%,多糖脱色率达到88.90%,多糖回收率为80.15%。这一工艺为红毛五加粗多糖的脱色和脱蛋白提供了一种高效且实用的方法。
This study aimed to establish a proteinase-reversed micelle method for simultaneous deproteinization and decolorization of crude Acanthopanax giraldii Harms polysaccharides (cAHP). According to the results of single-factor test, CTAB concentration, pH value and polysaccharide solution-reverse micelle volume efficiency were determined as the optimized conditions, and response surface methodology was then used to evaluate the interaction of several experimental parameters. The weight assignment method was applied to balance the deproteinization efficiency, decolorization efficiency and polysaccharide recovery efficiency of proteinase-reversed micelle. The process of decolorization and deproteinization of crude Acanthopanax giraldii Harms polysaccharides with proteinase-reverse micelle was obtained. The crude polysaccharide solution was adjusted to pH 6.5, and papain of concentration of 1.2×104 U/mL was added. After enzymatic hydrolysis at 40 ℃ for 1.5 h, the solution was adjusted to pH 4.0 and NaCl was added to concentration of 0.4 mol/L. And then, the reverse micelle solution (n-hexanol:isooctane: H2O = 5:65:30, V∶V, containing CTAB of concentration of 0.12 mol/L) was added in a ratio of 4∶1 (V∶V). After shock for 5 min, the water phase was collected by centrifugation. Under the optimal conditions, the decolorization efficiency was 84.71%, the decolorization efficiency was 88.90% and the polysaccharide recovery efficiency 80.15%. This process provides an efficient and practical method for the decolorization and deproteinization of Acanthopanax giraldii Harms polysaccharides.
