工業(yè)葡萄糖用途：

Industrial glucose uses:

1、工業(yè)葡萄糖在污水中的作用：污水處理中為什么要加工業(yè)葡萄糖污水處理調(diào)試期間投加工業(yè)葡萄糖等是為了提供碳源，這是為了更好的培養(yǎng)細菌，提高污水的可生化性，有效改善污泥的親和性，比尿素的效果要來的快。若運行的系統(tǒng)中COD、BOD不足以供給菌種生長繁殖的話，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、工業(yè)級葡萄糖皮革工業(yè)使用處理皮革，如鞋底革、皮箱革等，可以*大其柔軟性和做鉻鞣料的還原劑。

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、工業(yè)葡萄糖用做鋼鐵表面清洗劑：鋼鐵表面如需要鍍缽、鍍鉻、鍍錫、鍍鎳以適應(yīng)特殊用途時，如制造馬口鐵，鍍鋅板，表面鍍鉻（電度）等，其鋼坯表面均需經(jīng)過嚴(yán)格清洗，使鍍層物與鋼鐵表面牢固結(jié)合，這時候其清洗藥劑中添加葡萄糖酸鈉將會達到十分理想的效果。

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、工業(yè)葡萄糖還可以作水泥摻合劑：水泥中添加一定數(shù)量葡萄糖酸后，可增加混凝土的可塑性和強度，且有阻滯作用，即推遲混凝土的*初與*終凝固時期，例如添加0.15%的葡萄糖酸,可將混凝土的初凝固時間延長10倍以上,也就是將混凝土的可塑時間從幾小時延長至幾天,而不影響其牢度

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

應(yīng)用領(lǐng)域

application area 

（一）發(fā)酵工業(yè)

（1） Fermentation industry

微生物的生長需要合適的碳氮比，葡萄糖作為微生物的碳源，是發(fā)酵培養(yǎng)基的主料，如抗生素、味精、維生素、氨基酸、有機酸、酶制劑等都需大量使用葡萄糖，同時也可用作微生物多聚糖和有機溶劑的原料。

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）食品工業(yè)

（2） Food industry

目前結(jié)晶葡萄糖主要用于食品行業(yè)，隨著生活水平的提高和食品行業(yè)科技的不斷發(fā)展，葡萄糖在食品行業(yè)的應(yīng)用越來越廣泛。

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）化學(xué)工業(yè)

（3） Chemical industry

葡萄糖在工業(yè)上的應(yīng)用也很廣，在印染制革工業(yè)中作還原劑，在制鏡工業(yè)、熱水瓶膽鍍銀及玻璃纖維鍍銀等化學(xué)鍍銀工業(yè)也常用葡萄糖作還原劑。

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.

葡萄糖在制革工業(yè)鉻鞣劑制造中的應(yīng)用：鉻鞣劑是制造輕革（鞋面革、服裝革）的鞣劑。用鉻鹽制革已有 100年的歷史。所制皮革具有收縮溫度高、彈性好、耐撓曲、耐水洗、堅實耐用等特點。

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.

制備方法

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類水溶液，經(jīng)凈化、濃縮而成。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，示稱“玉米糖漿”。

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.葡萄糖可以淀粉為原料，經(jīng)鹽酸或稀硫酸水解制得。也可以淀粉為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.
