为了进步一水葡萄糖的产量以及葡萄糖的纯度,人们提出了各种各样的方 案,例如国度学问产权文献提供一种医药用结晶葡萄糖的制法[申请号: 86106624.3],该创造的办法是运用脱支酶和葡萄糖淀粉酶与淀粉水解物作用,得到含量葡萄糖97%纯度以上的高纯度糖液,再将糖液精致浓缩,就能够制得结晶葡萄糖。上述办法固然在一定水平上进步了一水葡萄糖的产量以及葡萄糖的纯度,但是其在消费过程中,需求大量的脱支酶和葡萄糖淀粉酶,从而进步了消费的本钱,另外,运用该办法,容易产生大量的废液,容易招致环境的污染以及资源的糜费。CN201510267883.7针对上述药用葡萄糖消费办法存在消费本钱高容易产生大量的废液,从而招致环境的污染等技术问题,提出一种设计合理制备时间短消费本钱低且废液量少的药用一水葡萄糖消费工艺。包括以下步骤:
In order to improve the production of monohydrate glucose and the purity of glucose, various schemes have been proposed. For example, the National Knowledge Property Document provides a method for the preparation of crystalline glucose for medical use [Application No. 86106624.3]. The method of creation is to use debranching enzyme and glucoamylase to react with starch hydrolysate to obtain the content. Crystalline glucose can be prepared from high-purity sugar solution with 97% purity of glucose and refined concentration of the sugar solution. Although the above-mentioned method has improved the production of monohydrate glucose and the purity of glucose to a certain extent, it needs a large number of debranching enzymes and glucose amylase in the process of consumption, thus improving the cost of consumption. In addition, using this method, it is easy to produce a large number of waste liquids, which can easily lead to environmental pollution as well as environmental pollution. The waste of resources. CN201510267883.7 Aiming at the technical problems such as high consumption cost and easy to produce a large amount of waste liquor, which will cause environmental pollution, this paper proposes a process for the consumption of medicinal glucose in one water with a reasonable preparation time, low consumption cost and a small amount of waste liquor.
