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

The preparation method of a kind of direct-edible living sea cucumber

Technical field

The present invention relates to the preparation method of a kind of direct-edible living sea cucumber.

Technical background

Sea cucumber is the precious marine product that people are familiar with, and ranks first of the marine products eight delicacies.Since ancient times, sea cucumber is the famous and precious good merchantable brand of nourishing and fit keeping function.The research of modern science also shows, not only be rich in the nutritional labeling of needed by human body such as amino acid, vitamin and trace element in the sea cucumber, also contain multiple bioactivator such as acid mucopolysaccharide, saponin and collagen etc., and pharmacologically active is very extensive, so beche-de-mer can strengthen immunity comprehensively apace for human body supplements the nutrients.The product of the original sea cucumber form of main in the market maintenance has fresh and alive sea cucumbers, dried sea-cucumber, waterishlogged Stichopus japonicus, instant holothurian, sea cucumber can etc.Existing dried sea-cucumber and waterishlogged Stichopus japonicus are the traditional products of sea cucumber, but the nutritional labeling loss greatly in sea cucumber drying and the reconstitution process, wherein water soluble ingredients such as sea cucumber mucopolysaccharide, selenka, sea cucumber peptide run off in a large number, and the alimentary health-care function of sea cucumber is had a greatly reduced quality.Instant holothurian and sea cucumber can are the products that sea cucumber process boiling and sterilization obtain, the defective of these products is that sea cucumber is through behind the high temperature high pressure sterilizing, it is soft mashed that holothurian collagen generation hydrolysis, sea cucumber body wall become in storage, loses the due elasticity mouthfeel of sea cucumber.

Because fresh and alive sea cucumbers has highly active autolytic enzyme, fresh and alive sea cucumbers is difficult to fresh-keeping, if direct freezing preservation still needs complicated water to send out process when edible, nutritive loss is big, so fresh and alive sea cucumbers consumption has bigger restriction.

Summary of the invention

The purpose of this invention is to provide the preparation method of a kind of direct-edible living sea cucumber,, remedy the above-mentioned deficiency of prior art to fill up the market vacancy of beche-de-mer products.

The preparation method of a kind of direct-edible living sea cucumber is characterized in that the fresh and alive sea cucumbers surface clean totally, cuts the sea cucumber belly open, remove the sea cucumber internal organ, and clean up, add the deionized water of 0.5～10 times of sea cucumber weight, handled 0.5～5 hour at 10～50 ℃ of following ultrasonic waves; The protease that adds sea cucumber weight 0.1～5% again to deionized water was handled 0.5～10 hour under 20～50 ℃ and 0.01～0.5MPa pressure; Sea cucumber is taken out from gained solution, the enzyme solutions on the sea cucumber body wall is cleaned up, promptly obtain direct-edible living sea cucumber with the clear water of 1～5 times of sea cucumber weight.

After the invention has the advantages that fresh and alive sea cucumbers is through processing, the loss of nutritive effect such as sea cucumber mucopolysaccharide, selenka composition is little, and thermal denaturation does not take place sea cucumber albumen, and collagen takes place softening, direct-edible living sea cucumber has good taste and elasticity, can directly eat.

The specific embodiment

The present invention is a raw material with bright sea cucumber, is direct-edible living sea cucumber through processing after physical method and the enzyme processing, and its making step is:

(1) the fresh and alive sea cucumbers surface clean is clean, cut the sea cucumber belly open, remove the sea cucumber internal organ, and clean up with clear water, add the deionized water of 0.5～10 times of sea cucumber weight, handled 0.5～5 hour at 10～50 ℃ of following ultrasonic waves;

(2) add the protease of sea cucumber body weight 0.1～5% to deionized water, under 20～50 ℃ and 0.01～0.5MPa pressure, handled 0.5～10 hour;

(3) sea cucumber is taken out from gained solution, the enzyme solutions on the sea cucumber body wall is cleaned up, promptly obtain direct-edible living sea cucumber with the clear water of 1～5 times of sea cucumber weight.

Embodiment

It is clean to get the bright cleaning sea cucumber of 10kg, cuts the sea cucumber belly open, removes the sea cucumber internal organ and clean up the back with clear water to add in the 10kg deionized water, handles 1 hour at 50 ℃ of ultrasonic waves; In deionized water, add the 0.1kg neutral proteinase, under 30 ℃ and 0.5MPa pressure, handled 3 hours; Sea cucumber is taken out from gained solution, the enzyme solutions on the sea cucumber body wall is cleaned up, promptly obtain direct-edible living sea cucumber with the 30kg clear water.

The weight of the deionized water described in the present embodiment can be 5～100kg, can handle 0.5～5 hour at 10～50 ℃.The protease that can add sea cucumber weight 0.1～5%, the protease that uses can be pepsin, trypsase, flavor protease, papain, neutral proteinase or bromelain, can handle 0.5～5 hour down and under 0.01～0.5MPa pressure at 20～50 ℃ behind the adding protease.

Claims

1. the preparation method of a direct-edible living sea cucumber is characterized in that the fresh and alive sea cucumbers surface clean totally, cuts the sea cucumber belly open, remove the sea cucumber internal organ, and clean up, add the deionized water of 0.5～1.0 times of sea cucumber weight, handled 0.5～5 hour at 10～50 ℃ of following ultrasonic waves; The protease that adds sea cucumber weight 0.1～5% again in deionized water was handled 0.5～10 hour under 20～50 ℃ and 0.01～0.5MPa pressure; Sea cucumber is taken out from gained solution, the enzyme on the sea cucumber body wall is cleaned up, promptly obtain direct-edible living sea cucumber with the clear water of 1～5 times of sea cucumber weight.
