工业葡萄糖用途：

Industrial glucose uses:

1、工业葡萄糖在污水中的作用：污水处理中为什么要加工业葡萄糖污水处理调试期间投加工业葡萄糖等是为了提供碳源，这是为了更好的培养细菌，提高污水的可生化性，有效改善污泥的亲和性，比尿素的效果要来的快。若运行的系统中COD、BOD不足以供给菌种生长繁殖的话，就需要另外投加，以防污泥老化，生物活性降低。

1. The role of industrial glucose in sewage: why should industrial glucose be processed in sewage treatment? The purpose of adding industrial glucose during sewage treatment commissioning is to provide carbon source, which is to better cultivate bacteria, improve the biodegradability of sewage, and effectively improve the affinity of sludge, which is faster than the effect of urea. If COD and BOD in the operating system are insufficient to supply the growth and reproduction of bacteria, additional dosing is required to prevent sludge aging and biological activity reduction.

2、工业级葡萄糖皮革工业使用处理皮革，如鞋底革、皮箱革等，可以*大其柔软性和做铬鞣料的还原剂。

2. Industrial grade glucose leather industry uses processed leather, such as sole leather, leather case leather, etc., which can improve its softness and act as a reductant for chrome tanning.

3、工业葡萄糖用做钢铁表面清洗剂：钢铁表面如需要镀钵、镀铬、镀锡、镀镍以适应特殊用途时，如制造马口铁，镀锌板，表面镀铬（电度）等，其钢坯表面均需经过严格清洗，使镀层物与钢铁表面牢固结合，这时候其清洗药剂中添加葡萄糖酸钠将会达到十分理想的效果。

3. Industrial glucose is used as a cleaning agent for steel surface: if the steel surface needs to be plated with pots, chromium, tin, nickel to adapt to special purposes, such as making tinplate, galvanized sheet, surface chromium plating (electricity), the surface of its billet needs to be strictly cleaned to make the coating firmly combined with the steel surface. At this time, the addition of sodium gluconate to its cleaning agent will achieve a very ideal effect.

4、工业葡萄糖还可以作水泥掺合剂：水泥中添加一定数量葡萄糖酸后，可增加混凝土的可塑性和强度，且有阻滞作用，即推迟混凝土的*初与*终凝固时期，例如添加0.15%的葡萄糖酸,可将混凝土的初凝固时间延长10倍以上,也就是将混凝土的可塑时间从几小时延长至几天,而不影响其牢度

4. Industrial glucose can also be used as cement admixture: after adding a certain amount of gluconic acid to the cement, the plasticity and strength of concrete can be increased, and it has a blocking effect, that is, delaying the * initial and * final setting periods of concrete. For example, adding 0.15% gluconic acid can prolong the initial setting time of concrete by more than 10 times, that is, extending the plastic time of concrete from a few hours to a few days without affecting its fastness

应用领域

application area 

（一）发酵工业

（1） Fermentation industry

微生物的生长需要合适的碳氮比，葡萄糖作为微生物的碳源，是发酵培养基的主料，如抗生素、味精、维生素、氨基酸、有机酸、酶制剂等都需大量使用葡萄糖，同时也可用作微生物多聚糖和有机溶剂的原料。

The growth of microorganisms requires an appropriate carbon nitrogen ratio. Glucose, as the carbon source of microorganisms, is the main material of fermentation medium, such as antibiotics, monosodium glutamate, vitamins, amino acids, organic acids, enzyme preparations, etc., which require a large amount of glucose. At the same time, it can also be used as the raw material of microbial polysaccharides and organic solvents.

（二）食品工业

（2） Food industry

目前结晶葡萄糖主要用于食品行业，随着生活水平的提高和食品行业科技的不断发展，葡萄糖在食品行业的应用越来越广泛。

At present, crystalline glucose is mainly used in the food industry. With the improvement of living standards and the continuous development of science and technology in the food industry, glucose is more and more widely used in the food industry.

（三）化学工业

（3） Chemical industry

葡萄糖在工业上的应用也很广，在印染制革工业中作还原剂，在制镜工业、热水瓶胆镀银及玻璃纤维镀银等化学镀银工业也常用葡萄糖作还原剂。

Glucose is also widely used in industry as a reductant in the printing and dyeing and leather industry, as well as in the mirror industry, silver plating on hot water bottles and silver plating on glass fibers.

葡萄糖在制革工业铬鞣剂制造中的应用：铬鞣剂是制造轻革（鞋面革、服装革）的鞣剂。用铬盐制革已有 100年的历史。所制皮革具有收缩温度高、弹性好、耐挠曲、耐水洗、坚实耐用等特点。

Application of glucose in the manufacture of chrome tanning agents in leather industry: chrome tanning agents are tanning agents for the manufacture of light leather (shoe upper leather, garment leather). Chrome salt has been used in leather making for 100 years. The leather has the characteristics of high shrinkage temperature, good elasticity, flexibility resistance, water washing resistance, firmness and durability.

制备方法

Preparation method

1.由食用玉米淀粉用食品*酸和/或酶部分水解后所得的糖类水溶液，经净化、浓缩而成。由于水解程度的不同，所含D-葡萄糖的量，可相差很大。由玉米淀粉制得者，示称“玉米糖浆”。

1. It is purified and concentrated from the sugar aqueous solution obtained from the partial hydrolysis of edible corn starch with food * acid and / or enzyme. Due to the different degree of hydrolysis, the amount of D-glucose can vary greatly. Those made from corn starch are known as "corn syrup".

2.葡萄糖可以淀粉为原料，经盐酸或稀硫酸水解制得。也可以淀粉为原料在淀粉糖化酶的作用下而制得。

2. Glucose can be prepared from starch by hydrolysis with hydrochloric acid or dilute sulfuric acid. It can also be prepared with starch as raw material under the action of starch glucoamylase.
