Problems solved by technology

The preservative uses phosphate as a water-retaining agent to improve the water retention of aquatic products and reduce the loss of water in aquatic products. However, the phosphate content in the preservative is at least 50%. Excessive phosphate will make aquatic products unpleasant. The astringent taste of the metal will make the muscle tissue rough, affecting the flavor and taste of aquatic products. On the other hand, consumers who eat too much aquatic products with added phosphate will cause blood coagulation and cause harm to the human body.

Abstract

The invention discloses a tuna antistaling agent and a usage method thereof. The tuna antistaling agent comprises the following ingredients by weight : 5-10 parts of marine low-temperature lysozyme, 3-8 parts of nisin, 15-20 parts of bentonite, and 300 parts of water. The tuna antistaling agent uses marine low-temperature lysozyme and nisin as the main active ingredients, and uses modified bentonite as an adsorption carrier. The bonding properties of bentonite is employed to coat the modified bentonite film adsorbed with the marine low-temperature lysozyme and nisin on the surface of the tuna, so as to effectively reduce the loss of active ingredients in the antistaling agent, and extend the preservation time of tuna. At the same time, water retention properties of bentonite can prevent the intracellular nutrient losses due to tuna dehydration, so as to ensure the freshness of tuna.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of aquatic products, in particular to a tuna fresh-keeping agent and a using method thereof. Background technique [0002] Tuna is a general term for several genera of fish with a breastplate in the bony fish class Perciformes, also known as tuna and tuna, and is a highly migratory fish that lives in the middle and upper waters of the ocean , mainly in the tropical, subtropical and temperate waters of the Pacific Ocean, Atlantic Ocean, and Indian Ocean. There are 5 genera and 17 species of common tuna. Mainly include albacore tuna, Atlantic tuna, yellowfin tuna, bigeye tuna, bluefin tuna, skipjack tuna, etc. Tuna meat is fresh and tender, with high protein content, biological value as high as 90, and excellent amino acid combination; it is rich in DHA, EPA and other biologically active highly polyunsaturated fatty acids, which can promote brain development and effectively prevent cardiovas...
