US 9,173,911 B2 · Method for producing vegetable cell sap concentrate and means for the production thereof

Abstract

The invention relates to extracting biologically active substances from raw vegetable matter, consists in using a liquefied carbon dioxide and can be used in the pharmaceutical, perfume-and-cosmetic and food industries. The aim of the invention is to produce a cell sap concentrate by using liquefied carbon dioxide for the irradiation thereof. The inventive method consists in extracting a milled matter by means of liquefied carbonic acid at room temperature and in separating an oil fraction, wherein the extraction is carried out at a high rate of the liquefied carbonic acid with a proportion of not less than 11 of carbonic acid per 1 g of extracted vegetable cell sap and a vegetable cell sap concentrate is produced by separating the oil fraction from a water fraction.

A method for producing plant cell sap concentrate from Siberian fir comprising the steps of:

milling freshly collected woody verdure of Siberian fir;
extracting the milled woody vendure in a flow-through extractor at a temperature of 20° C. and a pressure of 64 atmospheres for 3 hours using liquefied carbon dioxide, wherein the liquefied carbon dioxide is added from a storage chamber that is elevated at a height of at least 8 meters above the extractor, to provide an oily fraction and an aqueous fraction, wherein the aqueous fraction is the plant cell sap concentrate;
separating the oily fraction from the plant cell sap concentrate;
and
collecting the plant cell sap concentrate;
wherein no water is added to the woody verdure of Siberian fir before or during the extracting step.
