Ready-to-eat special flavor fish product subjected to cold smoking, and production process thereof

Abstract

The invention belongs to the field of processing of aquatic products, and particularly relates to a ready-to-eat special flavor fish product subjected to cold smoking, and a production process thereof. The production process of the special flavor fish product comprises the following steps: using freshwater fish, a composite curing agent and a compound seasoning as raw materials, cutting the freshwater fish into square blocks after scaling, killing, gill removing, gutting removing, head removing and washing, then performing vacuum rolling and curing on the blocks, using a runner to absorb moisture of the blocks to realize drying at a low temperature, performing vacuum rolling for seasoning, and performing high-temperature sterilization and other processes to obtain the ready-to-eat special flavor fish product subjected to cold smoking. According to the invention, the curing process combines the curing agent with the vacuum rolling and curing, the drying manner that the runner is used to absorb moisture to realize drying at the low temperature is combined with a way that a surface air cooler is used to cool, and the compound seasoning is combined with the vacuum rolling technology, so that not only can the curing agent, the compound seasoning and a fish body be uniformly fixed, but also the curing time, the seasoning time and the drying time are remarkably reduced, the production cost is reduced, the fish tissue is promoted to be tighter, the texture and the taste are improved, the oxidation of highly unsaturated fatty acids in the fish body can be avoided, benzopyrene can not be produced, and the quality and safety of the product can be remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of deep processing of aquatic products, and in particular relates to a production process of instant fish products with cold-smoked flavor and products thereof. Background technique

[0002] Fish is one of the high-protein foods, and the protein absorption rate is as high as 96%, which is easily digested and absorbed by the human body. Freshwater fish also contain highly unsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which account for 25-35% of the total fatty acids. These substances can promote the growth and development of brain cells, improve memory, and also have the functions of preventing and treating cardiovascular and cerebrovascular diseases and Alzheimer's disease. Therefore, aquatic products and their processed foods are very popular among consumers.
