The invention discloses a method for pickling a raw crab-clip composite preservative and a salted raw crab paste thereof, which is made of nisin, ε-polylysine, tea polyphenol and citric acid. The amount of the nisin is 0.01-0.03% of the mass of the marinated raw crab paste, 0.02-0.04% of the ε-polylysine, 0.01-0.03% of the tea polyphenol, and 0.005-0.015% of the citric acid. . The composite preservative of the invention adopts a safe and reliable formula, effectively inhibits the growth and reproduction of microorganisms, reduces the total number of colonies, inhibits the metabolic activities of spoilage bacteria to form volatile base nitrogen and fat oxidation products, and at the same time, can be used for pickling raw crab paste products to improve food safety. The method of pickling a raw crab paste by the composite preservative can lengthen the shelf life of the preserved raw crab paste, and the preserved raw crab paste product stored at -18 ° C can have a shelf life of more than 6 months. |
