The purpose of amylase is to decompose starch and increase the filtration speed in juice processing, as well as vegetable processing, syrup manufacturing, glucose and other processing and manufacturing.
1. Adding amylase to textiles can make the clothes softer and will not damage the skin, making it suitable for pajamas.
2. Secondly, amylase can also be used in the process of vegetable processing, which can keep vegetables fresh and bright, and can also play a good role in the process of making syrup.
3. Isoamylase can also be used for microbial fermentation. The yeast powder used to steam steamed buns is obtained from it. It can also increase a lot of speed in the juice processing process, greatly improving industrial production. .
Extended information
1. Alpha-amylase is widely distributed in animals (saliva, pancreas, etc.), plants (malt, mountain vegetables) and microorganisms. Microbial enzymes are almost always secreted.
This enzyme uses Ca2 as an essential factor and serves as a stabilizing factor and activating factor. Some amylase is Ca2-independent. Amylase acts on both amylose and amylopectin, indiscriminately cutting off the α-1,4-chains inside the sugar chain randomly.
2. β-amylase is widely distributed. The difference from α-amylase is that it cleaves α-1,4-glucan chains from the non-reducing end in units of maltose. Mainly found in higher plants (barley, wheat, sweet potato, soybean, etc.), but also reported to exist in bacteria, milk, and mold.
For unbranched substrates like amylose, maltose and a small amount of glucose can be completely decomposed.
3. γ-amylase. γ-amylase (γ-amylase) sequentially cleaves α (1→4) chain glycosidic bonds and α (1→6) chain glycosidic bonds from the non-reducing end of the starch molecule, and cuts off the glucose residues one by one.
Similar to β-amylase, the free hemiacetal hydroxyl group produced by hydrolysis undergoes translocation to release β-glucose. Regardless of whether it acts on amylose or amylopectin, the final product is glucose.
