摘要
介绍一种双酶法生产葡萄糖酸锌的新工艺。新工艺采用葡萄糖作为主要原料,葡萄糖氧化酶在过氧化氢酶的协同作用下将葡萄糖氧化为葡萄糖酸,同时流加一定浓度的氧化锌悬液进行中和,最终生成葡萄糖酸锌。研究葡萄糖浓度、pH、温度、空气流量对葡萄糖酸锌合成工艺的影响,并对葡萄糖酸锌结晶的最适宜条件进行初步研究。通过本工艺生产的葡萄糖酸锌纯度可达99.6%,可用于食品、医药、饲料、化妆品等诸多领域。
A new production method for zinc gluconate production is introduced in this article. According to this method, selected enzyme of Glucose oxidase catalyzes the oxidation of glucose, as substrate, to gluconic acid in the presence of oxygen supply with simultaneous production of hydrogen peroxide （H2O2） while gluconic acid is neutralized by zinc oxide to produce zinc gluconate. The present paper studies the influences of following parameters such as glucose concentration, pH, temperature, air flow rate, and optimum crystallization conditions on zinc gluconate processing. The purity of the zinc gluconate can reach up to 99.6%. Zinc gluconate produced using enzymatic method can be used in the area of food, pharmaceutical, feed, cosmetic industries, etc.
