Problems solved by technology

The oil yield rate of cold pressing technology is low, and the crude oil needs to be refined through decolorization, deacidification, deodorization, etc. The whole process is in an aerobic environment, and the fatty acid structure in the green thorn fruit oil changes through the action of lipoxygenase , and new impurities and chemicals are introduced, and its natural qualities are destroyed
In addition, oil products made by pressing are easy to oxidize and difficult to store.
These deficiencies have influenced the wider application of green thorn fruit oil

Abstract

The invention provides a preparation process for prinsepia utilis royle grease. The preparation process comprises the following steps: firstly, peeling the collected prinsepia utilis royle grease fruits, elutriating the peeled prinsepia utilis royle grease fruits with clear water and cleaning; secondly, keeping the clear water on the surfaces of the fruits cleaned by elutriating away from being dried in the sun or dried in the air by sunlight direct irradiation; thirdly, parching the fruits at the temperature of 90-120DEG C for 30-180 minutes; fourthly, crushing the parched fruits by using a crushing machine and sieving the crushed fruits through a sieve with 40-100 meshes; fifthly, feeding the crushed and sieved prinsepia utilis royle raw materials into an extraction kettle and carrying out supercritical extraction; and sixthly, separating the materials obtained in the fifth step in a separation kettle with the separation pressure of 5-12Mpa and the temperature of 38-60DEG C. According to the method, prinsepia utilis royle grease can be obtained on the premise that a fatty acid structure is not damaged and has favorable permeability and easiness in absorption.

Description

technical field [0001] The invention relates to a preparation process of green thorn fruit oil. Background technique [0002] Supercritical fluid extraction technology has been researched and developed for more than 100 years. my country has introduced supercritical fluid extraction technology since the 1980s and studied it. The basic principle of this technology is to use carbon dioxide under a certain pressure and temperature, which has both good gas diffusivity and liquid solubility, to extract active ingredients from animal and plant raw materials, and realize separation and collection through pressure and temperature control. Supercritical CO 2 The extraction technology has the advantages of low extraction temperature, high extraction efficiency, no solvent residue, no pollution discharge, high product quality, etc. It is one of the more advanced extraction and separation technologies in the world at present. [0003] Prinsepia utilis royle, Latin name Prinsepia utili...
