Embodiment 1

[0019] A kind of fast dehydration method of fresh jellyfish, concrete steps are as follows:

[0020] 1) Pretreatment of fresh jellyfish

[0021] The said pre-treatment is to separate the head and umbrella part of the fresh jellyfish after catching with a knife along the ventral surface of the umbrella body, remove the sting flower in the body cavity, and process the head and umbrella part of the jellyfish separately; remove the umbrella part of the jellyfish White ointment film and blood coat, place the head of the jellyfish until the dirt seeps out, remove the tentacles, and then rinse with water;

[0022] 2) Shredded

[0023] The jellyfish umbrella part processed in step 1) is cut into 5mm~10mm thick and 5mm~10mm wide thick wires with a shredding machine;

[0024] 3) Salt alum stirring dehydration treatment

[0025] The shredded jellyfish that has been cut is put into the pickling pond, starts the blender, and adds the salt alum mixture simultaneously, and the addition is...

[0039] 2) Shredded

[0040] The jellyfish umbrella part processed in step 1) is cut into 5mm~10mm thick and 5mm~10mm wide thick wires with a shredding machine;

[0041] 3) Salt alum stirring dehydration treatment

[0042] The shredded jellyfish that has been cut is put into the pickling pond, starts the blender, and adds the salt alum mixture simultaneously, and the addition is...

Embodiment 3

[0055] 1) Pretreatment of fresh jellyfish

[0056] The said pre-treatment is to separate the head and umbrella part of the fresh jellyfish after catching with a knife along the ventral surface of the umbrella body, remove the sting flower in the body cavity, and process the head and umbrella part of the jellyfish separately; remove the umbrella part of the jellyfish White ointment film and blood coat, place the head of the jellyfish until the dirt seeps out, remove the tentacles, and then rinse with water;

[0057] 2) Shredded

[0058] The jellyfish umbrella part processed in step 1) is cut into 5mm~10mm thick and 5mm~10mm wide thick wires with a shredding machine;

[0059] 3) Salt alum stirring dehydration treatment

[0060]The cut jellyfish shreds are dropped into the pickling pond, start the mixer, and add the salt alum mixture simultaneously, and the addition is 6% of the weight of the jellyfish shreds; the preparation ratio of the salt alum mixture is table salt: alum=1...

Abstract

The invention relates to a rapid dehydration method for fresh jellyfish, and belongs to the technical field of aquatic product storage and processing. The method comprises the following steps: separating head parts and umbrella parts of caught fresh jellyfish, and completely cleaning and shredding the fresh jellyfish; putting the cut shredded jellyfish into a pickling pool, starting a stirrer, adding a salt-alum mixture at the same time, carrying out stirring, fishing out the shredded jellyfish to be drained, then performing microwave heating and dehydration, controlling the dehydration rate to be 82%-88%, and cooling and draining the shredded jellyfish after heating is finished; and adding the shredded jellyfish into saline water for soaking and storing. According to the method, the freshjellyfish processing dehydration time is greatly shortened, so that the problems that the residual amount of aluminum in a processed finished product is high, aluminum-containing waste water discharged in the processing process pollutes the environment and the like due to the fact that fresh jellyfish processing dehydration time is long and the alum usage amount is large are solved.

Description

technical field [0001] The invention belongs to the technical field of aquatic product storage and processing, and in particular relates to a fast dehydration method for fresh jellyfish. Background technique [0002] Jellyfish belongs to the coelenterate phylum, the class of jellyfish, the order of jellyfish, the family of jellyfish, and the genus jellyfish. Jellyfish are widely distributed in my country's coastal and coastal areas, and are the main large-scale economic jellyfish in my country's coastal areas. Jellyfish is rich in protein, inorganic salts and various vitamins, etc., and has high nutritional value. It is a high-protein, low-fat, low-calorie nutritious food. [0003] The water content of fresh jellyfish is more than 95%, and the harvest season of jellyfish is summer and autumn when the temperature is higher, so it is easy to rot if it is not handled in time. The processing dehydration method of fresh jellyfish has two kinds at present, and a kind of is tradi...
