Problems solved by technology

However, the shelf life of chilled fresh aquatic products is short, and they are affected by the environment during storage and transportation. Therefore, enhancing the shelf life of chilled aquatic products is an urgent problem to be solved.
At present, there is no research on the combination of snakehead mucus, Flammulina velutipes polysaccharide, and dragon fruit stem juice to prepare a compound biological preservative

Abstract

The invention belongs to the technical field of meat product preservation methods and discloses a novel fish paste preservative as well as a preparation method and application thereof. The preservative comprises the following raw material substances in parts by weight: 30-70 parts of chitosan, 20-50 parts of tea polyphenol, 15-35 parts of whey protein, 5-15 parts of snakehead mucus, 2-15 parts of needle mushroom polysaccharide and 45-55 parts of water; and the preservative also can comprise 5-10 parts of pitaya stem and leaf juice. The preparation method comprises the following steps: uniformly mixing chitosan, tea polyphenol, whey protein, snakehead mucus, needle mushroom polysaccharide and water by virtue of ultrasonic treatment of ultrasonic waves, carrying out ultra high pressure treatment on the uniformly mixed liquid, and uniformly mixing the solution in combination with micro-jet high pressure homogenization treatment, thereby obtaining the novel fish paste preservative.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping methods for meat products, and in particular relates to a novel fresh-keeping agent for minced fish and its preparation method and application. Background technique [0002] Due to the influence of various physical and chemical factors, microorganisms, etc., minced fish is prone to spoilage. This not only affects its color and smell, but also creates food safety issues. In addition to the water activity and the composition and properties of the minced fish itself, some studies have shown that the main cause of spoilage is the bacterial activity above the freezing temperature. In the context of a market where minced fish is the main raw material for processing, it is very necessary to solve the problem of keeping fresh minced fish fresh and maintain its quality and freshness to the greatest extent to meet market demand. [0003] At present, the preservation of aquatic products mainly adopts...
