Production method of direct-edible raw sea-slug

Abstract

The invention relates to a preparation method of a raw sea cucumber which can be directly eaten. The preparation method is characterized in that internal organs are removed from a fresh sea cucumber, then the fresh sea cucumber is washed clean, and added with deionized water which is 0.5-10 times of the weight of the sea cucumber for ultrasonic processing at the temperature of 10-50 DEG C for 0.5-5 hours to obtain liquid; the obtained liquid is added with protease accounting for 0.1-5% of the weight of the sea cucumber at the temperature of 20-50 DEG C under the pressure of 0.01-0.5MPa for 0.5-10 hours to obtain solution; the sea cucumber is taken out from the obtained solution, the enzyme solution on the surface of the sea cucumber body is washed clean by clean water which is 1-5 times of the weight of the sea cucumber to obtain the raw sea cucumber which can be directly eaten. Sea cucumber protein prepared by the preparation method has no thermal denaturation, nutrient and beneficial ingredients such as sea cucumber mucopolysaccharide, sea cucumber saponin, and the like has little loss; collagen is softened but the sea cucumber does not shrink. The fresh sea cucumber has good mouth feeling and elasticity, and can be directly eaten.

Description

technical field [0001] The invention relates to a method for preparing directly edible raw sea cucumbers. technical background [0002] Sea cucumber is a familiar sea treasure, ranking first among the eight seafood treasures. Since ancient times, sea cucumber has been a valuable product for nourishing and strengthening the body. Modern scientific research also shows that sea cucumber is not only rich in amino acids, vitamins and trace elements and other nutrients needed by the human body, but also contains a variety of biologically active substances such as acidic mucopolysaccharides, saponins and collagen, etc., and has a wide range of pharmacological activities. Therefore, eating sea cucumber can comprehensively and quickly supplement nutrition for the human body and enhance immunity. At present, the main products on the market that maintain the original shape of sea cucumbers include fresh and live sea cucumbers, dried sea cucumbers, dried sea cucumbers, ready-to-eat se...

AI Technical Summary

Problems solved by technology

Existing dried sea cucumbers and water-fed sea cucumbers are traditional products of sea cucumbers, but the nutritional components of sea cucumbers are greatly lost during the drying and rehydration process, in which a large number of water-soluble components such as sea cucumber mucopolysaccharides, sea cucumber saponins, and sea cucumber peptides are lost, making the nutritional content of sea cucumbers The health function is greatly reduced

Ready-to-eat sea cucumbers and canned sea cucumbers are products obtained by steaming and sterilizing sea cucumbers. The defect of these products is that after the sea cucumbers are sterilized under high temperature and high pressure, the collagen of the sea cucumbers will be hydrolyzed, and the body walls of the sea cucumbers will become soft and rotten during storage, losing the natural properties of sea cucumbers. elastic mouthfeel

[0003] Since fresh sea cucumbers have highly active autolytic enzymes, it is difficult to keep fresh sea cucumbers fresh. If they are directly frozen and stored, they still need a complicated watering process when eating, and the loss of nutrients is large, so the consumption of fresh sea cucumbers is relatively limited.
