Fish extract beverage production method

Abstract

The invention discloses a fish extract beverage production method. The fish extract beverage production method comprises the following steps that 1 fish is killed mechanically; 2 fish serum is obtained by grinding; 3 fish grease slurry and fish protein slurry are separated and obtained by using pulse electric shock treatment; 4 antioxidant treatment is conducted on the fish grease slurry; 5 the fish protein slurry is treated by a papain enzymolysis technology; 6 the fish grease slurry and the fish protein slurry are mixed and matched, and emulsion quid is obtained by using homogeneous ultrafine treatment; 7 vacuum flash evaporation degassing treatment is conducted, and disinfection and disinfection are conducted; 8 an edible additive is added, and fish extract beverage is obtained. The method has the advantages that live fish can be stopped struggling as fast as possible, a glycogen component, capable of converting to lactic acid, of a fish body is effectively reserved, self anticorrosion effect of fish flesh is increased, the fresh quality of the fish flesh is improved, and the nutrition ingredient of the fish flesh is kept; self tenderization of the fish flesh can be further promoted, a next process of enzymolysis is conducted on the fish flesh smoothly, and it is effectively guaranteed that nutrient such as DHA and EPA of the fish grease slurry is not damaged by oxidation. The added value of silver carp and bighead carp is improved, and low-benefit fresh water breeding industry is promoted into a virtuous circle.

Description

technical field [0001] The invention relates to the technical field of food deep processing, in particular to a method for preparing a fish juice drink. Background technique [0002] my country is a big freshwater fish breeding country, and the breeding area and output of freshwater fish rank first in the world, and more than 50% of them are silver carp and bighead carp with low added value. Freshwater fish contains extremely rich unsaturated fatty acids and high-grade protein, and also contains a large amount of nutrients such as DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid) and taurine that are necessary for the human body . However, silver carp and bighead carp have the defects of strong fishy smell and many bony spurs, which limit the edible value of this type of fish. Infants and young children can't eat directly, and kindergartens dare not give it to children, and children and even many adults are unwilling to eat it. Moreover, the problem of fresh-keeping...

Problems solved by technology

Due to the above reasons, people have given up eating fish food to directly supplement the necessary nutrients such as DHA and EPA for the human body. At the same time, it has also led to a vicious cycle of breeding losses for silver carp and bighead carp, which greatly limits the sustainable development of my country's freshwater fish farming industry. develop
