SU921496A1 - Method of extracting meat from crustacea - Google Patents

Description

I

The invention relates to a technique for processing seafood for food purposes and relates to methods for extracting sa marine marine crustaceans, predominantly Antarctic krill.

Since krill catches can exceed the current level of catch in the oceans, krill has become one of the real large-scale sources of animal protein product. The most valuable constituent of krill is pure cervix, the chemical composition of which is close to that of crabs and shrimps. Pure cervix may be used to produce natural canned foods or frozen.

There is a known method of extracting small crustacean meat by mechanical action for destroying the shell, transporting fish in a stream of water and separating the meat in it from the shell fl.

The disadvantage of this method is the possibility of deformation of the crustacean necks and their partial crushing, which reduces the quality and presentation of the resulting product.

There is also known a method for extracting the sa sa of small crustaceans by exposing them to an air jet with

10 at a relative speed of 200-500 m / s to destroy the shell and separate it from meat 2.

This method is closest to the invention by its technical essence and the achieved result and allows to eliminate the disadvantages of the previous method. However, being a simple and speedy process known

20 is relatively energy intensive, since compressors are required to obtain high-speed parameters of a jet of compressed air;

Claims (2)

Claim 1. The method of extracting meat of small crustaceans, mainly krill, by exposing them to a working medium with a stream to destroy the shell and separate it from the meat, meat and fish, in order to reduce energy costs and improve the quality of product, as a working medium using a liquid supplied with a relative speed of 10-30 m / s. 2. The method according to π.1, on the basis of the search for the fact that, as the working medium, water is used with a temperature from 0 to 15 ° C.
