definition
Biological preservatives refer to a class of high-efficiency preservatives obtained from organisms through biological culture, extraction and separation techniques, which have the effect of inhibiting and killing microorganisms. Food is rich in nutrients and is easily contaminated by microorganisms and spoilage. In order to ensure the safety of food, people use many methods to preserve food, such as salting, canning, and refrigeration. However, under certain conditions, the use of preservatives as an auxiliary means of preservation has a significant effect on preventing food spoilage. Therefore, preservatives are one of the important food additives and are widely used in the food industry.

Plant sources
Edible fragrant plants are originally used for flavoring and flavoring in food. Recent studies have shown that these substances also have antibacterial and antiseptic effects, which can inhibit the growth of infectious microorganisms and prolong the price period of food. These spices include garlic, ginger, pepper, cloves, cinnamon, nutmeg, star anise, fennel, etc. For example, garlic extract has a strong inhibitory and killing effect on dozens of bacteria and fungi in food spoilage, and allicin is the most important functional component. Terpenoids in ginger extract also have strong bactericidal effect.
Animal sources
At present, many biological preservatives from animals are reported to be insect antibacterial peptides, chitosan and protamine.
Microbial sources
Biological preservatives of microbial origin are antibacterial substances produced by microbial metabolism, mainly organic acids, peptides or precursor peptides. Its mechanism of action is mainly to form micropores on the cell membrane, which leads to the increase of cell membrane permeability and the destruction of energy generation system, thereby inhibiting the growth of microorganisms. Currently, the approved and widely used microbial preservatives in the world are Streptococcus lactis peptide, kojic acid and natamycin, which are important products of fermentation engineering.
