Research Progress in the Application of Enzyme Disinfectants

Disinfection methods are divided into physical methods, chemical methods and biological methods. The use of biological enzymes as disinfectants should be one of the biological disinfection methods. Biological disinfection is the use of animals, plants, microorganisms and (or) their metabolites to eliminate or kill pathogenic microorganisms in the environment, so as to achieve the purpose of controlling the spread of diseases. Biological disinfectants refer to biological products with in vitro bactericidal effects. According to the nature and source of biological disinfectants, they are currently mainly divided into:

` Plant-derived disinfectants: The antibacterial active ingredients in higher plants are mainly essential oils. Essential oils are compounds of esters, aldehydes, ketones and terpenes. Terpenes, alkaloids, flavonoids, steroids, organic acids, proteins, etc. also have antibacterial effects.

aAntibacterial peptide: A small molecule polypeptide with antibacterial activity induced by organisms. At present, there are more than 1,000 antibacterial peptides isolated from organisms. With the increasing maturity of peptide chemical synthesis technology, many artificially synthesized antimicrobial peptides have entered clinical research in the world.

bBacteriophage: Bacteriophage can specifically infect a certain kind of bacteria, penetrate into bacterial cells and replicate itself, and at the same time produce lyase, highly specific and rapid lysing bacterial cell walls, killing bacteria and releasing new viruses.

c Biological enzymes: Biological enzymes are widely present in higher animals, protozoa, insects, plants and various microorganisms. It is a highly efficient, highly specific and bio-enzyme biocatalyst. With the rapid development of modern life science and biotechnology, the compounding of different enzyme disinfectants and combining them into a composite biological enzyme disinfectant can overcome the shortcomings of a single disinfection spectrum of enzyme disinfectants. Enzyme disinfectants have attracted more and more attention because of their high efficiency, safety and theoretically reusable advantages.

Main types of enzyme disinfectants

1.1 Chitinase

Chitinase is a linear polysaccharide composed of N-acetylglucosamine connected by β-1,4 bonds, and is the structural substance of most bacterial cell walls. Chitinase produced by infected plants can destroy chitin in bacterial cell walls. At present, the research on chitinase at home and abroad is mainly for its antibacterial mechanism, and there is no relevant application research.

1.2 Peroxidase

The peroxidases known to have good bactericidal effects on pathogenic microorganisms include haloperoxidase, lactoperoxidase (LPO) and glucose oxidase. At present, the research on peroxidase at home and abroad is still in the experimental stage, and there is no product application.

1.3 Ribozyme

Ribozymes (RNA enzymes) is a piece of RNA with enzymatic activity, with high specificity and non-toxic characteristics, and it is one of the hotspots of antiviral research in recent years. The antiviral effects of ribozymes are currently mostly in the experimental research stage, and some scientists have applied ribozymes to the research of anti-HIV infection. The antiviral treatment of ribozymes has shown hope, but there is no research on the application of ribozymes as disinfectants at home and abroad.

1.4 Phage Lyase

Bacteriphage lysins are a type of protein encoded by bacteriophages that are synthesized at the late stage of genome replication. They can hydrolyze the peptidoglycan of the bacterial cell wall to kill the bacteria. Studies have shown that phage lyase has a good bactericidal effect on pathogenic bacteria such as Streptococcus pneumoniae, Bacillus anthracis, Lactobacillus, Staphylococcus aureus and so on. Bacteriphage lysins is still in the stage of laboratory research and clinical trials.

1.5 Lysozyme

Lysozyme, also known as muramidase or N-acetylmuramidegycanohydrlase, is an alkaline enzyme that can hydrolyze mucopolysaccharides in pathogenic bacteria. It is widely found in various tissues of the human body, egg whites of birds and poultry, tears of mammals, saliva, plasma, milk and other body fluids, among which egg whites are the most abundant.

Detailed Introduction to Several Commonly Used Food Additive Enzyme Preparations

Trypsin
Trypsin is the main protease in the pancreas and is the most thoroughly studied of all proteases. Mainly because it is not only widely used in the food industry, it is also an important digestive enzyme. It is white to light brownish yellow amorphous powder, soluble in water, almost insoluble in ethanol, glycerin, chloroform and ether. Trypsin has high specificity and can only act on a few peptide bonds. It is usually extracted from the pancreas of pigs or cattle. Although the number and sequence of amino acid residues in mammalian trypsin vary slightly with different animal species, they are all serine proteases and the mechanism of action is also the same. Trypsin is very stable when the pH is lower than 6, and the most stable when the pH is 3. Higher pH values will produce autocatalysis, that is, self-digestion and be destroyed. The optimum pH range for enzymes acting on proteins and most synthetic substrates is 7-9. Trypsin can inhibit the oxidized flavor of milk, produce hydrolyzed protein, and is also used for roasting and meat tenderization.

Papain
Compared with other proteases, papain has higher thermal stability. Papain has a strong ability to hydrolyze protein and can be used to improve the nutritional value or functional properties of vegetable protein.

(1) Mainly used for cold resistance of beer, that is, to hydrolyze the protein in beer to avoid turbidity after cold storage. The dosage is 0.5^5mg/kg, and immobilized papain has been used. The advantage is that the enzyme treatment is arranged after beer pasteurization, and the use of immobilized enzymes can more accurately control the degree of protein degradation, so that some protein can be retained in the beer, which is very beneficial to stabilizing the beer foam. Meat tenderization, that is, the collagen in the hydrolyzed muscle protein, is used for post-mortem injection of 0.5-5 mg/kg. Used for loosening biscuits and cakes, it can replace sulfite, which has the effect of reducing gluten and improves safety.

(2) In the processing of animal and plant protein foods, such as protein hydrolysates and high-protein beverages, it can improve product quality and nutritional value, and improve product digestion and absorption rate. Adding this product and other enzymes to soy sauce brewing can increase the yield and amino acid content. When making beer wort, adding this product and other enzymes can reduce the amount of malt and reduce costs.

(3) It can be used as a substitute for rennet and a coagulant for cheese.

Chymosin
There are three main sources of rennet used in cheese production: animal rennet (such as calf rennet, lamb rennet, pepsin, etc.); plant rennet (such as papain, ficin, etc.); Microbial rennet (such as mucor rennet, bacterial rennet, etc.). Among them, animal rennet was the earliest and most widely used in cheese production. Renal enzyme is one of the most valuable enzymes in the food industry because it is widely used to produce cheese. It is a carboxyl protease, which is mainly extracted from the fourth stomach water of unweaned calves, goats or lambs to obtain inactive zymogen. The zymogen undergoes partial hydrolysis and turns into active enzymes, and its molecular weight is reduced from 360,000 to 31,000. Clear amber to dark brown liquid, or white to light brown-yellow powder, slightly salty and hygroscopic. The dried product has stable activity and is unstable in solution. The pH value of the aqueous solution is about 5.8, the optimum coagulation pH value for milk is 5.8, and the optimum temperature is 37-43°C. It is inactive below 15°C and above 55°C. This enzyme cleaves between phenylalanine and leucine in casein in cow’s milk, resulting in curdling. 1g of commercial rennet can be coagulated within 40 minutes at 35°C by adding 10 liters of milk.

In recent years, the world’s cheese production has increased year by year, and the demand for chymosin has also been increasing. People’s attention has been paid to plant rennet and microbial rennet, which are widely sourced and inexpensive.

Protease
Protease is almost white to light brownish yellow amorphous powder or liquid. It is soluble in water, and the aqueous solution is generally pale yellow. But it is almost insoluble in ethanol, chloroform and ether. The main function is to hydrolyze protein into low molecular weight peptone, peptides and amino acids. Natural products exist in animals, plants and microorganisms, and industrial applications are mainly produced by molds. The optimum temperature for products made from Aspergillus oryzae at pH 6.0 is 45-50°C. The product made from Aspergillus niger is also called acid protease, with an optimum pH of 2.5 and an optimum temperature of 45°C. Copper ions or manganese ions with a concentration of 2×10-3mol have a strong activation effect, while silver ions and mercury ions have an inhibitory effect.

Lipase
Lipase is mainly used in cheese manufacturing to defat and produce special flavors (mainly to increase volatile acids and flavor fatty acids), fat modification, and lipid hydrolysis to prevent the fats and oysters in some dairy products and chocolate products from being spoiled. It is an excellent preparation to make milk chocolate and cream cake produce special flavor. Add the protein to break down the fat that may be mixed into it, thereby improving its foaming ability. In winemaking, adding lipase can shorten the winemaking time and improve the flavor of wine.
