通过优化γ-聚谷氨酸的化学法水解法,降低化学法水解的条件。经过研究确定了1M的磷酸以2:1的比例加入反应体系中,在80℃反应40-60分钟可以将100万分子量的γ-PGA完全降解。
By optimizing the chemical hydrolysis of γ-polyglutamic acid, conditions for chemical hydrolysis are reduced. It has been determined that 1 M phosphoric acid is added into the reaction system at a ratio of 2: 1, and 100 M molecular weight γ-PGA can be completely degraded by reaction at 80 ° C. for 40-60 minutes.
