Application Of Enzyme Preparation
Jan 18, 2021
The enzyme preparation industry is a high-tech industry, which is characterized by low consumption, high catalytic efficiency, and strong specificity. It is an industry that serves other related industries. Its application fields cover light industry, food, chemical industry, medicine, agriculture, energy and environmental protection.
1. Food industry
There are many types of food enzyme preparations in China. Among them, carbohydrate enzymes, protein enzymes, and dairy enzymes account for a larger proportion of food enzyme preparations, accounting for 81.7%. Enzyme preparations commonly used in food processing mainly include the following: papain, transglutaminase, elastase, lysozyme, lipase, glucose oxidase, isoamylase, cellulase, superoxide dismutase Enzymes, bromelain, ficin, ginger protease, etc.
The enzyme preparations that China has approved for use in the food industry include α-amylase, glucoamylase, immobilized glucose isomerase, papain, pectinase, β-glucanase, grape oxidase, and α-acetolactate deamination. Enzymes, etc., are mainly used in fruit and vegetable processing, baking, and dairy processing.
The amylase industry has developed rapidly, the output has doubled, and the variety has gradually increased. By 2006, the output had exceeded 5 million tons. The starch residue protein content and starch gelatinization properties in the enzymatic wet milling process are better than those in the traditional wet milling process. Due to the addition of protease, not only the soaking time is shortened, but the protein yield is not reduced but improved. New enzyme preparations are being used in the production of injection glucose, liquid glucose syrup, high maltose syrup, fructose syrup and various oligosaccharides. Instead of sucrose, starch sugar has been used in food processing, candy, beer and beverage production.
2. Textile industry
In the 1980s, textile enzyme preparations represented by amylase, protease, cellulase, etc. were mainly used for fabric desizing, denim finishing and silk degumming. They were widely used in industry and also represented textile biology. Technology began to rise. After entering the 21st century, the application fields of Chinese enzyme preparations in the textile industry have gradually expanded, including fiber modification, raw hemp degumming, pre-treatment for printing and dyeing, printing and dyeing wastewater treatment, and garment processing. At present, the processing technology of textile enzyme preparations has involved almost all textile wet processing fields, and the market scale is showing a steady increasing trend.
3. Feed industry
Feed enzyme preparation is a new type of feed additive that has emerged with the continuous development of feed industry and enzyme preparation industry in recent years. It has the functions of improving nutrient digestibility, improving the stability of compound feed quality, and reducing environmental pollution. As a kind of high-efficiency, non-toxic, non-side effects and environmentally friendly green feed additives, feed enzyme preparations have become the fastest growing and most powerful part of the world's industrial enzyme industry, and its application effects have been recognized worldwide. Chinese feed enzyme preparations have been added to feed since the 1980s.
At present, there are more than 20 types of feed enzymes in China, mainly including: amylase, protease, xylanase, β-mannanase, cellulase, β-glucanase, phytase and compound enzymes. These enzyme preparations can be divided into two categories: 1) Mainly degrade polysaccharides and biological macromolecules, including proteases, lipases, amylases, saccharification enzymes, cellulases, xylanases, and mannanases. The main function is to destroy the plant cell wall and fully release the cell contents; 2) Degrade phytic acid, β-glucan, pectin and other anti-nutritional factors, mainly including phytase, β-glucanase and Pectinase, its main function is to degrade the pectin components of cell wall xylan and intercellular substance, and improve the utilization rate of feed.
