Application of enzyme in light chemical industry?
1. It can be widely used for degreasing leather making, fur, wool spinning, silk spinning, paper making, detergent, food processing, medicine, natural rubber and so on.

2. As a detergent, enzyme and alkaline protease were added to the washing powder to make a double-enzyme washing powder. Analysis of product market and economic benefit: taking detergent as an example. At present, the market share of enzyme-containing detergents in European countries reaches 90%, while that in Japan reaches 80% (mainly protease and cellulase), while that in China only accounts for 10%, and only a single protease is added. Therefore, this product can fill the blank of domestic compound detergent and is expected to enter the international market. According to the annual output of 3,000 tons, the annual output value can reach10,000 yuan, and the predicted annual benefit can reach 2 million yuan.

3. The application of enzymes in bioengineering, biosensor, environmental protection, medicine and so on is also expanding day by day. It can be said that enzymes have become an indispensable part of the national economy. In real life, almost all new technologies such as food, clothing, housing and transportation are inseparable from enzymes.

4. α -amylase produced by fungi catalyzes the degradation of starch into sugar, bread and other foods that can be used by yeast.

Protease (biscuit relaxant) hydrolyzes protein in flour in the process of making biscuits; In dairy production, whey protein is hydrolyzed. Is beneficial to the digestion and absorption of protein nutrition in food.

5. Brewing industry:

Amylase, protease and glucanase in malt. Starch and protein are degraded into monosaccharides, amino acids and polypeptides, which can be used by yeast, thus increasing the yield of ethanol.

β -glucanase decomposes β-glucan, reduces the viscosity of wort, accelerates the filtration speed of wort, and avoids beer turbidity caused by β-glucan.

Removal of chaotic substances produced during beer storage by papain

6. Meat cooking: Papain (tender meat powder) bromelain breaks down the collagen of meat, making the meat tender and smooth. The optimum temperature of papain is 60℃, and the optimum pH is 7-7.5. Do not use in high temperature and acidic environment.

7. Dairy industry:

Coagulant for cheese production, which can be used to decompose protein.

Lactase degrades lactose into glucose and galactose to obtain lactose-free dairy products, which is beneficial to the digestion and absorption of dairy products;

Fruit juice production: pectinase and cellulase. Treat pulp, improve juice yield, shorten juice time and improve juice quality.

Sugar industry: Amylase converts starch into glucose and various syrups.

Glucose isomerase is used to convert glucose into fructose with high sweetness to produce high fructose syrup.

8. Textile industry:

Starch saccharifying enzyme

It is widely used in textile desizing, in which bacterial amylase can tolerate the high temperature operating conditions of 100 ~ 1 10℃.

Cellulase replaces sand washing process to treat denim cotton and improve denim quality.

Tannery industry: trypsin softens leather by removing certain protein from fur, and can also be used for leather depilation.

9. Medical and pharmaceutical industry: trypsin is used to promote wound healing and dissolve thrombus, and can also be used to remove necrotic tissue and inhibit the reproduction of contaminated microorganisms;

Penicillin acylase converts penicillin, which is easy to form drug resistance, into ampicillin with stronger bactericidal power.

L one-day asparaginase is used to treat cancer and deprive cancer cells of nutrients needed for growth.

Lysozyme (mucopolysaccharide lytic enzyme) destroys the cell walls of Gram-positive bacteria and kills them. Has antibacterial, hemostatic, repercussive, and wound healing promoting effects, and can also be used for treating rhinitis, pharyngolaryngitis, and oral ulcer.

Tyrosinase (neurotransmitter) is produced, and dopa is used to treat Parkinson's disease.

Urokinase and streptokinase thrombolytic agents are used to treat thrombosis.

Proteases (multi-enzyme tablets) are used to treat dyspepsia, and many enzymes can also be used as diagnostic reagents in medical treatment.
