Embodiment 1

[0028] (1) Pretreatment: Take fresh crabs and wash them with 2-10°C water;

[0029] (2) Bacteria reduction treatment: the cleaned crabs are treated with ozone water for bacteria reduction treatment, the concentration of ozone water is 2.5mg / L, the treatment time is 15min, and the mass ratio of fresh crabs to ozone water is 1:2;

[0030] (3) Cleaning: After ozone treatment, wash the crabs with 2-10°C water until the water is clean;

[0031] (4) Bleeding and meat extraction: After the cleaned and drained crabs are heated in a vacuum heater, the shells are quickly opened for bloodletting and meat extraction. The conditions of the vacuum heating are a vacuum degree of 0.06MPa, a temperature of 55°C, and a treatment time of 20 minutes;

[0032] (5) Sorting and grading: multiple selection to remove impurities and broken shells. Picking and grading according to processing specifications;

Abstract

The invention discloses a processing method for keeping tenderness of canned crab meat. The method comprises the following steps of: cleaning fresh crabs, performing bacteria reducing treatment by adopting ozone, performing vacuum heating, opening crab shells to take out meat, soaking the crab meat in treatment solution compounded by composite phosphate and nisin, canning, sterilizing, storing and the like. The method can effectively inhibit growth and reproduction of microbes, keeps the elasticity and the tenderness of the meat, and has good practical value and application prospect.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and in particular relates to a processing method for maintaining the tenderness of canned crab meat. Background technique [0002] Crab is the main economic crustacean in Fujian sea area. Crab is a delicacy in food, known as the folk proverb "a plate of crabs is the top dish". Crab meat is not only delicious, but also rich in nutrients, rich in protein, fat, a variety of microorganisms and calcium, phosphorus, sodium, potassium, magnesium and iron, zinc, selenium, copper, manganese and other trace elements, which are good for the body. Its nourishing effect is a favorite aquatic product. [0003] In recent years, with the improvement of residents' consumption level, crab products have gradually entered the people's table.
