摘  要:
以氧化淀粉为原料,采用酶解和发酵工艺来制备葡萄糖醛酸,以糖化液和发酵液中葡萄糖醛酸含量为评价指标,研究了葡萄糖醛酸制备工艺中的糖化条件、发酵条件。结果表明:糖化的最佳条件为:75 g氧化淀粉中加入2 m L糖化酶,在温度为55℃下反应12 h时,糖化液中的葡萄糖醛酸最高达7.79%;发酵的最佳条件为:25 m L糖化液中加2.0 g酵母粉,在35℃的水浴中发酵4 d时发酵液中的葡萄糖醛酸含量最高达28.03%。该研究为高含量葡萄糖醛酸的制备及其变性淀粉的应用提供了理论指导。

摘  要:
Using the oxidation starch as raw material,the glucuronic acid was obtained by the processes of saccharification and fermentation. The conditions of saccharifying enzyme reaction and the yeast fermentation was studied,and the glucuronic acid of saccharification liquid and fermented liquid was regarded as evaluation standard. The results showed that the optimal conditions of saccharifing were as follows:reaction at 55 ℃ for12 h and amount of saccharifying enzyme was 1 m L in the 75 g of oxidation starch. The optimal conditions of fermentation were 25 m L saccharification liquid with 2.0 g yeast,temperature of 35 ℃ for 4 d. The research provided the theoretical guidance for the preparation of high content of glucuronic acid and the application of oxidized starch.
