Abstract

The invention relates to a fish composite antifreeze agent and a preparation method thereof, and the fish composite antifreeze agent comprises the following raw materials by weight: 0.1-3% of trehalose, 0.1-3% of sodium chloride, 0.1-3% of glycerin, 0.1-1% of sorbitol, 0.01-0.3% of ascorbic acid, 0.01-0.3% of a bamboo leaf antioxidant, 0.01-0.1% of ethylenediamine tetraacetic acid, 1-5% of sodium pyrophosphate, 1-5% of sodium tripolyphosphate, and the balance of water. 0-1% of sodium hexametaphosphate and the balance of water. The surimi composite antifreeze agent disclosed by the invention has a relatively good application effect on fishes with different fat contents, not only can maintain the quality of frozen storage fishes, but also can provide technical support for producing high-quality surimi by using frozen fishes. After 90 days of freezing storage, the gel strength of the minced fillet produced by using the frozen storage fish treated by the fish composite antifreeze agent can be close to that of the minced fillet produced by fresh fish, so that the fish composite antifreeze agent has a better market application prospect.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a preparation method and application of a composite antifreeze agent for improving the quality of frozen fish. Background technique [0002] Freezing storage can delay food spoilage and has always been an important method of aquatic product processing in my country. In 2019, the national frozen aquatic product output has reached more than 15 million tons. However, protein is prone to denaturation during frozen storage, which leads to a decrease in the taste, texture and nutritional value of fish meat. Therefore, the research and application of antifreeze agents are of great significance to maintain the quality of aquatic products. Antifreeze can inhibit the growth of ice crystals and delay the freezing denaturation of fish protein, thereby reducing the impact of frozen storage on fish quality. Commonly used antifreeze agents for aquatic products include trehal...
