Embodiment 1

[0030] (1) Rinse the river crab, put it in a steamer, put it in a steamer, and steam it in boiling water for 15-20 minutes; peel off the crab navel, lift the crab cover at the opening, and remove the meat and crab roe from the crab cover and crab body. Cut off both ends of the crab legs with scissors, and take out the crab leg meat;

[0031] (2) Put the crab meat taken out into plastic retort bags (PET / AL / CPP type, 15×20cm, Hongchang Plastic Packaging Factory, Xindu Town, Tongcheng City), 200±10g / bag, and seal.

[0032] (3) The packaged river crab meat is sent to the pulse microwave equipment (Ruining Magnetoelectric Technology Application Research Institute, Xiaguan District, Nanjing), and the instantaneous output power is set to 350kw, the microwave frequency is 1250MHz, the spectrum width is 0.55MHz, and the pulse width is 3μs , Duty ratio 1:1000, pulse voltage 28kV, pulse microwave treatment for 4min.

[0033] (4) Take out the river crab meat processed by pulsed microwave...

Embodiment 2

[0039](1) Rinse the river crab, peel off the crab navel, lift the crab cover, discard the crab stomach, send it to the crab meat harvester (Shandong Zhucheng Yizhong Machinery Co., Ltd.) for crab meat collection, and collect the river crab meat paste;

[0040] (2) Pack the crab meat taken out into a clean glass bottle (180ml, hexagonal, 5.2cm in diameter, 8.5cm in height, 7cm in diagonal, Nantong Xinde Glass Bottle Products Co., Ltd.), open or seal with a plastic cover.

[0041] (3) The packaged river crab meat is sent to the pulse microwave equipment (Ruining Magnetoelectric Technology Application Research Institute, Xiaguan District, Nanjing), and the instantaneous output power is set to 380kw, the microwave frequency is 1300MHz, the spectrum width is 0.55MHz, and the pulse width is 3μs , Duty ratio 1:1000, pulse voltage 30kV, pulse microwave treatment for 3.5min.

[0042] (4) Take out the river crab meat that has been processed by pulsed microwaves, combine them into a larg...

Abstract

The invention discloses a method of reducing the irritability of river crab meat. The method comprises the following steps: (1) packaging raw materials: removing shells of river crabs and taking edible meat, crab cream or oil; putting the edible meat, crab cream or oil into a sealed plastic bag or a glass bottle; (2) carrying out pulse microwave treatment: putting the raw materials packaged in the step (1) into pulse microwave equipment and carrying out the pulse microwave treatment; and (3) carrying out double-enzyme enzymolysis, namely taking out the raw materials subjected to the pulse microwave treatment in the step (2), and adding papain and chymotrypsin to hydrolyze. By adopting a pulse microwave cooperated enzymolysis technology, allergens of the river crabs are sufficiently transformed under a high-intensity pulse microwave condition, and are decomposed under the action of the papain, so that the degradation of the allergens of the river crabs is effectively realized; and meanwhile, the temperature of the river crab meat is not raised by pulse microwaves and the original flavor and texture of the river crab meat can be kept.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for reducing the allergy to river crab meat. Background technique [0002] The scientific name of river crab is Chinese mitten crab, which is a rare freshwater product. It is delicious, nutritious, rich in protein and trace elements, and is known as a delicacy in food. According to the "Compendium of Materia Medica": crabs have the effects of relaxing muscles and nourishing qi, regulating stomach and eliminating food, dredging meridians, dispersing various heats, and dispersing blood stasis. [0003] But delicious river crab is not for everyone. Cases of allergies caused by eating crabs occur every year. River crab is a crustacean, and it is one of the eight categories of foods that are likely to cause allergies proposed by the Food and Agriculture Organization of the United Nations. Food allergy is a public health problem of global concern, and ab...
