Method for producing high-puffed crispy recreation grains by using frozen seafood mixed trash fish

Abstract

The invention provides a method for producing high-puffed crispy recreation grains by using frozen seafood mixed trash fish, belonging to the technical field of processing techniques of prepared food and aquatic product. The main process is as follows: removing fish scales, fish heads, internal organs, belly napes, bloodiness and the like of fresh or frozen seafood trash fishes, washing by clear water, cutting the fish into fish slices of 20mm*20mm*5mm, conducting a fishy smell removing treatment on the pre-treated fish for 2h by composite rinsing solution, then arranging the fish and composite antifreeze agent in a cutting and blending machine to cut and blend, freezing the cut and blended minced fillet at a lower temperature of (-20) DEG C, un-freezing the minced fillet which has been frozen for a certain time, adding accessories, beating and stirring uniformly, compacting the obtained minced fillet in a plastic mold, cooking, cooling, cutting into grains, and finally conducting a vacuum microwave pre-watering treatment and a pulse spraying negative pressure microwave drying treatment on the fish grains, thereby obtaining the high-puffed crispy recreation grains.

Description

Technical field [0001] A method for producing high-puffed leisure crunches by using frozen seafood mixed trash fish relates to fish dehydration processing. The invention belongs to the technical field of prepared food and aquatic product processing. Background technique [0002] About 70% of the world’s fish catches are processed and eaten, of which frozen products account for 29.8% and fresh products account for 29.2%. my country has abundant marine fish resources. For example, the annual catch of hairtail is more than 1 million tons, and the annual catch of small yellow croaker is more than 100,000 tons, but the proportion of small fish is more than 15%. Most of them are mainly frozen and fresh, resulting in a low processing rate of marine products in my country, mainly due to the lack of deep processing technology. In addition, the research on dehydration processing of fish products has been developing slowly. [0003] The raw material fish used in the present invention are mi...

[0022] From the analysis of existing literature and patents, it can be seen that there are relatively few studies on the recombination of seafood mixed small fish meat with carrots or purple sweet potatoes, and the recombination of seafood mixed small fish meat with carrots or purple sweet potatoes is pre-dehydrated by vacuum microwave. There is no report on the method of producing high-expansion casual crispy grains through pulse jet negative pressure microwave drying
