Problems solved by technology

[0004] The traditional methods of removing the skin of sea cucumbers from the East China Sea are fire roasting, sodium hydroxide, hydrogen peroxide, etc., but these methods are not suitable for control, cause serious nutritional loss, and there are still potential safety hazards; in recent years, enzymatic hydrolysis methods have been applied to the peeling of sea cucumbers from the East China Sea. However, due to the dense combination of the epidermis of East China sea cucumber, the enzymatic hydrolysis takes a long time, which is not conducive to industrial processing, and the long-term enzymatic hydrolysis will cause a large loss of nutrition in the edible part of the epidermis

Embodiment 1

[0019] (1) Take fresh East China Sea sea cucumbers and freeze them in a quick-freezing machine at -40°C.

[0020] (2) Approximately 100kg of East China Sea sea cucumbers after shaping are peeled in a grinder for 10-30 minutes, and the peeling process is always rinsed with tap water to maintain wet grinding;

[0021] (3) Remove the internal organs and surface silt of the sea cucumber, and weigh 50 kg of the microdermabrasion sea cucumber.

[0022] (4) Measure 50L of purified water, add 28 g of food grade pepsin, 56 g of papain, and 112 g of alkaline protease to the purified water to dissolve the enzyme hydrolysate. Place the microdermabrasion sea cucumber in the above enzymatic hydrolysis solution and soak it at 40°C for 0.5-1.5h to complete enzymatic peeling;

[0023] (5) Use a soft brush to remove the peeled skin and sand on the surface of the sea cucumber and clean it;

[0024] (6) Pick out individual sea cucumbers that are difficult to peel, measure 0.5 times the mass of purified wa...

Embodiment 2

[0027] (1) Take about 100 kg of frozen East Sea sea cucumbers and put them in a grinder for 10-30 minutes, and rinse them with tap water during the peeling process to keep them wet;

[0028] (2) Remove the internal organs and surface silt of the sea cucumber, and weigh 50kg of the microdermabrasion sea cucumber.

[0029] (3) Measure 50L of purified water, add 28g of food grade pepsin, 56g of papain, and 112g of alkaline protease to the purified water to dissolve to obtain an enzymatic hydrolysate. Place the microdermabrasion sea cucumber in the above enzymatic hydrolysis solution and soak it at 45°C for 0.5-1.5h to complete enzymatic peeling;

[0030] (4) Use a soft brush to remove the peeled skin and sand on the surface of the sea cucumber, and clean it;

[0031] (5) Pick out individual sea cucumbers that are difficult to peel, measure 0.5 times the mass of purified water, and prepare the enzyme hydrolysis solution according to the enzyme concentration of 0.3%, and soak it at 45°C fo...

Embodiment 3

[0034] (1) Take the dried sea cucumber from the East China Sea and soak it in tap water at room temperature for 24 hours. Change the water once to make the dried sea cucumber soften;

[0035] (2) Quick-freeze and finalize the Huiruan East Sea sea cucumbers in a -40℃ quick-freezing machine;

[0036] (3) Approximately 100 kg of East China Sea sea cucumbers after shaping are peeled for 10-30 minutes in a grinder, and the peeling process is always flushed with tap water to maintain wet grinding;

[0037] (4) Remove the internal organs and surface silt of sea cucumbers, weigh 50kg of microdermabrasion sea cucumbers;

[0038] (5) Measure 50L of purified water, add 28g of food grade pepsin, 56g of papain, and 112g of alkaline protease to the purified water to dissolve to obtain an enzymatic hydrolysis solution. Place the microdermabrasion sea cucumber in the above enzymatic hydrolysis solution and soak it at 50°C for 0.5-1.5h to complete enzymatic peeling;

[0039] (6) Use a soft brush to rem...

Abstract

The invention relates to an aquatic product processing method, in particular to a quick skinning method for Acaudina molpadioides Semper. The invention discloses the quick skinning method for the Acaudina molpadioides Semper. The method comprises the following steps of: setting the shape of a fresh Acaudina molpadioides Semper, mechanically grinding skin, cleaning and removing stain, skinning in an enzymolysis way, cleaning and removing stain, repeatedly carrying out enzymolysis and the like. When the skin is mechanically ground, more than a half of the silt-containing skin of the Acaudina molpadioides Semper can be removed, and the skin of the Acaudina molpadioides Semper can be completely removed within a short time by means of skinning in an enzymolysis way, so that the Acaudina molpadioides Semper body can be changed to be clean and translucent, an edible part of a wall of the inner layer body of the Acaudina molpadioides Semper can not be influenced, and the nutritional ingredients of the Acaudina molpadioides Semper can be furthest remained. The skin of an Acaudina molpadioides Semper product prepared by means of cleaning and packing is free from silt, and the heavy metal content reaches the standard, so that the Acaudina molpadioides Semper product can be used for dipping and processing or can be used as the raw material for deep processing.

Description

Technical field [0001] The invention relates to a method for processing aquatic products, in particular to a method for fast peeling of East Sea sea cucumbers. Background technique [0002] my country’s East China Sea is rich in wild sea cucumber resources. The East China Sea sea cucumber (scientific name Haitiangua) is mainly distributed in the soft mud of the East China Sea from the tidal zone to the depth of 80 meters. Research shows that the East China Sea has high collagen content and is rich in nutrients. It can often drag dozens to thousands of kilograms during operation, with huge natural reserves and low prices. The development of it into sea cucumber products has a broad market prospect. [0003] However, because the East China Sea sea cucumber is rich in collagen, it will become harder and harder to eat under high temperature. The East Sea sea cucumber lives in the mud on the seabed all year round, and the body surface secretes a mucus rich in amino acids and collagen. I...
