Enzyme preparation is an ecological and efficient catalyst, which has the characteristics of high efficiency, safety, energy-saving, ecology and environmental protection.
1 Application in the wine industry
Malt is the main raw material for beer. Poor malt quality or large amounts of auxiliary materials such as barley and rice will cause insufficient activity of amylase, glucanase, and cellulase. As a result, insufficient saccharification and insufficient protein degradation can affect the flavor and yield of beer. The use of microbial amylase, protease, p-glucanase and other preparations can supplement the deficiency of enzyme activity in malt.
2 Application in the feed industry
At present, corn is the main grain used as livestock feed, which has caused increasing shortages in corn supply. Therefore, we must fully develop and utilize resources-rich wheat, grain and bran. However, the anti-nutritional factor xylan exists in by-products such as wheat, cereals, and bran, which is a polypentacarbonose, and it is the second most abundant renewable material resource after relaying cellulose in nature. Xylanases can degrade xylan into oligosaccharides and xylose, which can effectively eliminate the adverse effects of the main anti-nutritional factor xylan in gramineous cereals, improve the nutrient utilization rate of cereals, and improve the ecological environment and control Animal diseases. In the end, the negative effects caused by the addition of antibiotics, hormones and high copper are avoided, which has obvious economic benefits and positive environmental protection significance.
3 Application in the medical industry
In recent years, enzymes have been increasing in clinical application due to their safety and high efficiency. For example, new enzymes such as urokinase, elastase, defibrase, plasmin, streptokinase, collagenase, and superoxide dismutase are widely used in various aspects such as cardiovascular and cerebrovascular diseases, hematological diseases, and anti-aging. At the same time, many enzyme preparations are used as first aid drugs.
Because the outer layer of plants and fungi both contain cell walls, the cell wall often becomes a key barrier preventing the effective components of traditional Chinese medicine from dissolving. With the help of enzyme engineering, the destruction and digestion of the cell wall can be achieved, so that the effective components of the cell can be more easily dissolved and the extraction efficiency can be improved. Such as cellulase, pectinase, etc. have the characteristics of directional decomposition of cell walls, improve the dissolution rate of effective substances, and have broad application prospects in the extraction of effective substances in traditional Chinese medicine.
A large number of studies have shown that the use of enzyme engineering technology to modify the active ingredients of traditional Chinese medicine is not only convenient and fast, but also can avoid the toxicity and pollution caused by organic chemical methods.
4 Development prospects of enzyme engineering
Enzyme preparation is an ecological and efficient catalyst, which has the characteristics of high efficiency, safety, energy saving, ecology and environmental protection. The development of enzyme engineering technology can effectively promote the improvement of the technical level in related fields, and is of great significance for the application industry to develop new products, improve quality, save energy and reduce consumption, and protect the environment.
In recent years, great breakthroughs have been made in the application of enzyme preparations, and the field of enzyme science has experienced unprecedented development. In addition to continuing to screen new enzyme sources and study their applicability in processing, new technologies such as protein engineering, synthetic enzyme technology, and non-aqueous enzymatic reactions continue to emerge. Promote people to make bold attempts in the research and application of enzymes, thereby greatly expanding the scope of application of enzymes.
The Naming and Characteristics of Restriction Endonucleases
Restriction enzymes, also known as restriction endonucleases, are enzymes that cut double-stranded DNA. Its cutting method is to cut the bond between the carbohydrate molecule and the phosphoric acid, and then create a nick on each of the two DNA strands without damaging the nucleotides and bases.
Introduction to Classification and Application of Cellulase
The optimum pH of cellulase is generally 4.5 to 6.5, which acts on cellulose and products derived from cellulose. Microbial cellulase is of great significance in converting insoluble cellulose into glucose and destroying cell walls in fruit and vegetable juice to improve the yield of juice.
Which Enzyme Preparations Are Often Used in Fruit and Vegetable Processing?
The so-called fruit and vegetable processing means to maximize the nutrient content of the fruit and vegetable through various processing methods, improve the edible value, and make the color, aroma and taste of the processed product more perfect.
