Abstract

The invention discloses biological food preservative. The biological food preservative comprises, by weight, 20-40 parts of nisin, 10-20 parts of trehalose, 4-8 parts of chitosan, 2-4 parts of glycine, and 2-4 parts of antioxidant of bamboo leaves. The biological food preservative made by mixing the various safe materials has no toxic and side effects, is simple in production process and high in stability, can be kept in the shade for a long period of time, and can be added in foods to maintain long-term antibacterial activity. The biological food preservative is insusceptible to temperature and pH, high in water solubility, convenient to add and high in bactericidal broad-spectrum, shelf lives of products can be prolonged evidently, and food safety can be improved. The biological food preservative overcoming the defects of chemical preservatives has the advantages of effectiveness, simplicity in operation, low cost and the like, and has evident economic and social benefits.

Description

technical field [0001] The invention relates to a food preservative, in particular to a food biological preservative. Background technique [0002] If the leftover food is not preserved in time, it will definitely taste bad. This is a well-known common sense---bacteria. I don’t know the power of bacteria, but it scares people when they say it, such as "botulinum", which can produce the most poisonous substance in the world - "botulinum toxin", which can be poisoned to death with only 1 gram of toxin 2 million people; "Aspergillus flavus", the "aflatoxin" it produces is one of the strongest carcinogens. Aflatoxin is 20 times more toxic than potassium cyanide, while botulinum toxin is 20,000 times more toxic than potassium cyanide. There are Shigella, pathogenic Escherichia coli, Vibrio parahaemolyticus, Salmonella, Staphylococcus aureus and so on. If food is contaminated with these harmful microorganisms during processing and storage, it is really terrible for consumers. ...
