Enzyme preparation refers to a kind of substance with enzymatic properties extracted from organisms. Its main function is to catalyze various chemical reactions in food processing and improve food processing methods. The enzyme preparations provided by Wuhan Deyi Biochemical Technology include catalase powder, α-glucosidase, cholesterol esterase, uricase, coenzyme A, aprotinin, chymotrypsin, acetylcholinesterase, elastase, cholesterol Oxidase, superoxide dismutase, enterokinase, bilirubin oxidase, purine nucleoside phosphorylase, glucose oxidase, thrombin, diaphorase, phosphoglucose mutase, hexokinase, horseradish peroxidation Enzyme, glucose-6-phosphate dehydrogenase, adenosine deaminase, ribonuclease, xanthine oxidase, lysozyme, and the like. Today, this small series will lead everyone to know what is the enzyme preparation, and what kinds of it?

1. What is the enzyme preparation?

Enzyme preparation refers to a kind of substance with enzymatic properties extracted from living organisms. The main enzyme preparation acts to catalyze various chemical reactions in food processing and improve food processing methods. China has approved six kinds of papain, α-amylase preparation, refined pectinase and β-glucose. Enzyme preparations are derived from organisms and are generally safer and can be used in appropriate amounts according to production needs. Enzyme preparations are a class of proteins that extract biocatalytic ability from animals, plants, and microorganisms. It is highly efficient, specific and active under suitable conditions (pH and temperature).

Second, the production process of enzyme preparation

The microorganisms producing the enzyme preparations include three major groups of filamentous fungi, yeast and bacteria, and mainly use the enzyme preparation gas bacteria.

Third, the classification of enzyme preparations

1. From the morphological classification, the enzyme preparation can be divided into a solid enzyme preparation and a liquid enzyme preparation.

2. Classification by application of enzyme preparations

 a: industrial enzyme preparations used as catalysts in industrial production, such as sputum-amylase, glucoamylase, glucose isomerase, penicillin acylase, aspartase, fumarase, etc.;

 b: an enzyme preparation for improving animal digestibility in feed, also known as feed enzyme preparation; an enzyme preparation for food production and processing, also known as a food enzyme preparation; a diagnostic enzyme preparation for clinical detection; for chemical analysis Enzyme assay preparation; pharmaceutical enzyme preparation for use as a drug; detergent enzyme preparation for detergent, and the like.

3. Classification according to the source of the enzyme According to the source of the enzyme, the enzyme preparation can be divided into a plant enzyme preparation, an animal enzyme preparation and a microbial enzyme preparation.

4. According to the different classification of enzyme production and processing methods For the application needs, the enzyme can be divided into free enzyme preparation, immobilized enzyme preparation, enzyme test paper, enzyme electrode and the like.

5. Classification according to the composition of the enzyme According to the type of enzyme contained in the enzyme preparation, it can be divided into a single enzyme preparation (containing only one enzyme such as starch) and a composite enzyme preparation. The complex enzyme preparation is mainly composed of one or several single enzyme preparations, mixed with other single enzyme preparations, or obtained by fermentation of one or several microorganisms. The complex enzyme preparation can utilize various synergistic effects of various enzymes to degrade various substrates and maximize the effect of the enzyme preparation.

6. Classification by enzyme content According to the concentration of the enzyme in the enzyme preparation, the enzyme can be divided into a common enzyme and a concentrated enzyme. Common enzymes have advantages such as low price and good effect. The concentrated enzyme is darker in color and has the characteristics of lower cost and less dosage.
