Abstract

The invention discloses an SVC-prefabricated sturgeon product processing method based on a sous vide cooking technology. According to the method, sturgeon is adopted as a main raw material, and flowing water freezing, shaping rinsing, pulse vacuum pickling, vacuum packaging, sous vide cooking, fast precooling and other novel food processing technologies are adopted so as to process the ready-to-eat sturgeon product. Through the method, the brightness and whiteness of the fish flesh can be improved effectively, the flexibility of the fish flesh is increased, the pickling efficiency is improvedsignificantly, and meanwhile a good fish tissue state is maintained; through coordinated adjustment of the vacuum degree, temperature and heat treatment time in the SVC technology, protein oxidation during heating is reduced, and the shelf life of the sturgeon product is prolonged; and the evaporation rate of water on the surface of the fish flesh which is obtained after SVC treatment is performedis reduced effectively through fast precooling. The sturgeon product which is produced by using the method has the advantages of convenient cooking, a long storage period of time, good retention of taste and nutrition and the like, and the method can be applied to product development of sturgeon.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing method of SVC prefabricated sturgeon meat products based on vacuum low heat technology. Background technique [0002] Sturgeon is a large economic fish with high edible value, rich in protein and essential amino acids for human body. At present, the output of Russian sturgeon meat in my country has accounted for 10% of the entire sturgeon aquaculture industry, but there are very few deep-processed products of sturgeon meat , the development and utilization of sturgeon meat has a good market prospect. [0003] Rinsing is an important process in the processing of sturgeon meat products. Traditional salt water rinsing will lead to the loss of protein in the fish meat, resulting in nutrient loss. The use of compound rinsing liquid can improve the brightness and whiteness of fish meat; calcium chloride and carboxymethyl Chitosan has a good antibacteria...
