Application Of Acid-Resistant Thermophilic Amylase In Various Fields

With the development of starch processing industry and the change of technological conditions, the varieties of enzymes need to be constantly updated and improved. Alpha-amylase has developed into a large and important family of industrial enzymes. According to the different properties of the enzyme, amylase can be divided into heat-resistant alpha-amylase, acid-resistant alpha-amylase, alkali-resistant alpha-amylase and salt-resistant alpha-amylase. Because of their stability under specific conditions, they are of great importance in relevant industries. In recent years, some enzyme manufacturers hope to operate at lower pH than the existing conditions, so acid-resistant alpha-amylase has been widely used, such as silage, fermented beverage, drug production, processing of industrial by-products, waste treatment and so on, with great application potential and development prospects.

In recent years, with the increasing clarity of the molecular composition and enzymatic properties of acid-resistant alpha-amylase, the value of its utilization has been gradually recognized. Therefore, acid-resistant alpha-amylase has attracted more and more attention and is widely used in brewing, food, medicine and other fields. More and more enzyme manufacturers begin to pay attention to the application of acid-resistant alpha-amylase.    

In food baking, the fermentation of bread needs reducing sugar, and the addition of acid fungus alpha-amylase makes the fermentation process stable to produce dextrin and maltose. Because the baking temperature of bread is very high, the fungus alpha-amylase will quickly lose its activity and prevent starch from over-gelatinization. Thus, bread with good quality, uniform internal structure, bulky volume and excellent taste can not only accelerate the fermentation speed and shorten the fermentation time, but also replace the carcinogenic potassium bromate in the existing Bread Improvers in China.

Taka amylase is a widely used digestive medicine in many countries, but the suitable pH of Aspergillus oryzae alpha-amylase is 4.5-6.0, which is easily destroyed by gastric acid (pH 2.0) in the stomach, resulting in a significant reduction in the medical effect. Therefore, acid-resistant alpha-amylase can be used to make digestive agents.

In addition, it can also be used for industrial waste liquor treatment, such as alcohol factory waste liquor treatment, acid alpha-amylase fermentation of alcohol waste liquor, so that it can be effectively converted, and the conversion liquefaction and saccharification process of alcohol production can be carried out in the same pH environment, to ensure the quality of alcohol production, reduce production costs, and achieve low waste emissions of enterprises.
