淀粉,是一种碳水化合物的高度聚合体,它是由两个多聚糖,即直链淀粉和支链淀粉组成的混合物。淀粉需要稳定的耐高温淀粉酶进行作用才能产生较短链的糊精。葡萄淀粉酶则主要用于葡萄糖浆、高果糖浆和用于酒精生产业的淀粉的水解。本产品是由黑曲霉(Aspergillus niger)优良菌种经深层发酵精制提炼而成。广泛应用于酿酒、淀粉加工、淀粉糖、酒精、味精和抗生素等行业。
工作机理
淀粉葡萄糖苷酶,糖化酶又称葡萄糖淀粉酶,能从淀粉分子的非还原性末端开始,水解α -1,4糖苷键,从而产生6-C和-D-葡萄糖。这种酶也能水解α-1,6-葡萄糖苷键。
产品特性
本产品的pH范围是: 4.0-4.5,适用的pH范围是3.0-5.5,本产品温度范围是40-60℃(104-140°F), 最佳温度范围是: 58-60℃ (136-140°F)。
使用方法
本产品用于酿酒酵母、淀粉、柠檬酸等的制造行业。该酶添加量为100-300U/g(pH4.0-5.0,温度60℃)
1.酒精工业(淀粉质为原料):醪液经蒸煮冷却至59±1℃时,加入糖化酶,拌均匀,保温30分钟,冷却后送入发酵。建议加酶用量为120-150U/g原料。(如果原料质量差,有霉烂变质时加酶量应提高到150-180U/g原料)。
2.白酒工业:固体酒培经蒸煮冷却至要求温度范围时,将糖化酶按要求量加入加浆水中,均匀加入酒培中(也可与大曲、酒母并用)。推荐使用量:250-300U/g原料。(注:糖化酶在白酒生产中应考虑发酵周期的长短而确定使用量。)
3.淀粉糖工业:添加比例为 100-300 U/g(pH为4.2-4.5)。混合物温度保持在60℃。
4.啤酒工业:在糖化作用或者发酵以前添加。
5.酒水酿造和醋制造业:添加带有酶的发酵酵母能够提高产率。

Starch is a high polymer of carbohydrates, and it is a mixture composed of two polysaccharides, namely amylose and amylopectin. Starch requires the action of stable high-temperature-resistant amylase to produce shorter-chain dextrins. Glucoamylase is mainly used for the hydrolysis of starch in the production of glucose syrup, high-fructose corn syrup, and alcohol. This product is refined and extracted from the excellent strain of Aspergillus niger through submerged fermentation. It is widely used in industries such as winemaking, starch processing, starch sugar, alcohol, monosodium glutamate, and antibiotics.
Working Mechanism
Starch glucosidase, also known as glucoamylase, can start from the non-reducing end of the starch molecule and hydrolyze the α-1,4 glycosidic bond, thereby producing 6-C and D-glucose. This enzyme can also hydrolyze the α-1,6 glucosidic bond.
Product Characteristics
The pH range of this product is 4.0-4.5, and the applicable pH range is 3.0-5.5.
The temperature range of this product is 40-60℃ (104-140°F), and the optimal temperature range is 58-60℃ (136-140°F).
Usage Methods
This product is used in the manufacturing industries of brewing yeast, starch, citric acid, etc. The enzyme addition amount is 100-300 U/g (at pH 4.0-5.0 and temperature 60℃).
1. Alcohol Industry (using starchy materials as raw materials): When the mash is cooked and cooled to 59±1℃, add glucoamylase, stir evenly, keep it warm for 30 minutes, and then cool it down before sending it for fermentation. The recommended enzyme addition amount is 120-150 U/g of raw material. (If the quality of the raw material is poor or it is moldy and deteriorated, the enzyme addition amount should be increased to 150-180 U/g of raw material.)
2. Liquor Industry: After the solid fermented grains are cooked and cooled to the required temperature range, add the required amount of glucoamylase into the slurry water, and then evenly add it to the fermented grains (it can also be used together with Daqu and yeast). Recommended usage amount: 250-300 U/g of raw material. (Note: The usage amount of glucoamylase in liquor production should be determined according to the length of the fermentation cycle.)
3. Starch Sugar Industry: The addition ratio is 100-300 U/g (at pH 4.2-4.5). Keep the temperature of the mixture at 60℃.
4. Beer Industry: Add it before saccharification or fermentation.
5. Wine Brewing and Vinegar Manufacturing Industry: Adding fermented yeast with enzymes can improve the yield.
Storage Conditions
This product is a biologically active substance and should be stored in a low-temperature and dry place, avoiding direct sunlight. When stored at room temperature (25℃) for three months, the enzyme activity is not lower than the marked enzyme activity. When stored at low temperature (below 25℃, but not frozen), its activity can be maintained for a longer time.
Precautions
This product is non-toxic and biodegradable. Avoid unnecessary contact, as long-term contact with proteins in some products may make some people sensitive to this product. After each contact with the product, wash hands with warm water and soap, and keep the product out of the reach of children.
