A METHOD FOR SEPARATION OF FOOD MATERIALS FROM YELLOW CROAKER USING SUPERCRITICAL OR SUBCRITICAL CARBON DIOXIDE

摘要

The present invention relates to a method for separating useful food materials from a yellow croaker, and more specifically, to a method for separating useful food materials from a yellow croaker, comprising: a step of drying and pulverizing a yellow croaker; a step of filling a pulverized yellow croaker power inside a reactor; a step of putting supercritical or subcritical carbon dioxide inside the reactor to allow the yellow croaker power filled inside the reactor and supercritical or subcritical carbon dioxide to be contact with each other; a step of discharging supercritical or subcritical carbon dioxide containing oil extracted from the yellow croaker powder by a separator; and a step of separating supercritical or subcritical carbon dioxide from the separator to collect the oil extracted from the yellow croaker powder. Since the present invention suggests a method for extracting various effective ingredients such as polyunsaturated fatty acid, highly concentrated protein, etc. from a yellow croaker by drying and pulverizing the yellow croaker and allowing the power and supercritical or subcritical carbon dioxide to be contact with each other, it is expected that not only food stability is pretty higher than the conventional method, which has to carry out extra removal process, but also highly concentrated protein of which lipid is removed can be obtained.
