AI Technical Summary

Problems solved by technology

Formaldehyde will cross-link the myofibrillar protein in the fish, making the meat hard and reducing the salt solubility of the protein, thus affecting the taste of the meat
At present, the water-retaining agents for aquatic products in the domestic and foreign markets are all strongly alkaline. After the aquatic products are soaked in the water-retaining agent, the oxidation of trimethylamine will be accelerated and decomposed into trimethylamine, dimethylamine, methylamine and formaldehyde, making the aquatic products pungent. Ammonia smell, thus affecting product quality and safety requirements

Abstract

The present invention relates to an aquatic product water retention and amine removing agent and a use method thereof, wherein the raw materials of the aquatic product water retention and amine removing agent comprise, by mass, 10-30% of saccharide, 5-15% of an organic acid salt, 1-5% of an organic acid, 5-10% of dihydrogen phosphate, 5-20% of bicarbonate, 1-5% of active calcium, 1-5% of hexametaphosphate, and 10-30% of edible salt. The use method comprises: preparing a soaking liquid, soaking an aquatic product into the soaking liquid for 1-4 h, stirring every an hour, and sequentially carrying out washing, draining, and rapid-freezing. According to the present invention, the aquatic product water retention and amine removing agent has effects of water retention, fresh keeping, prevention of protein denaturation during freezing and cold preservation, and effective removal and prevention of unpleasant odors or amine harmful substances; and the use method has the simple and convenient operation, and the problems of unpleasant odors or amine harmful substances, and the like during the aquatic product freezing process, the cold preservation process and the soaking process with the water retention agent can not be generated.

Description

technical field [0001] The invention relates to the technical field of food additives, in particular to a water-retaining and amine-removing agent for aquatic products and a use method thereof. Background technique [0002] Trimethylamine-N-oxide (TMAO) is the main component of non-protein nitrogen in the muscles of many marine fishes, and it is a characteristic umami component of aquatic products. However, after the death of the fish body and in the process of frozen storage, TMAO is easily transformed into trimethylamine and dimethylamine, which have a significant fish rot smell, under the activation of non-enzymatic factors such as trimethylaminase and ferrous ions. , methylamine and formaldehyde. Trimethylamine has certain toxic and side effects. Trimethylamine can inhibit the synthesis of DNA, RNA and protein, and has teratogenic effects on mouse embryos. Dimethylamine has a special smell of fish rot. It is a chemical raw material widely used in rubber vulcanization...
