Description

technical field

[0001] The invention belongs to the field of biological preservation, and in particular relates to a strain of bacillus amyloliquefaciens and its antibacterial protein and the application thereof in preservation of prawns. Background technique

[0002] Food preservation refers to the method of using physical, chemical and biological means to process food, so as to slow down its spoilage speed as much as possible and maintain its original freshness.

[0003] Due to the high protein and high moisture characteristics of seafood, it is easy to spoil during storage and transportation. Therefore, it is urgent to update the preservation technology of seafood. Common fresh-keeping methods for seafood include low-temperature preservation, modified atmosphere preservation, irradiation preservation, chemical preservation and biological preservation.

[0004] Refrigeration and preservation are divided into four preservation methods: refrigeration, ice temperature, sligh...
