Supercritical extraction method of tea seed oil

Abstract

The invention discloses a supercritical extraction method of tea seed oil. The supercritical extraction method comprises steps of washing, drying, smashing, CO2 supercritical extraction, and refrigerated centrifugation. According to the supercritical extraction method, squalene in tea seed oil is reserved as far as possible; CO2 supercritical extraction can be carried out at a temperature close to room temperature, so that oxidation and loss of thermosensitive substances can be prevented effectively; the supercritical extraction method is suitable for extraction of health-care tea seed oil; CO2 supercritical fluid extraction is simple in operation, short in extraction time, and low in extraction temperature; the supercritical extraction method is nontoxic and harmless, is capable of avoiding product oxidation, chemical reagent residual, pollution, and refining, and is an excellent method used for extracting health-care tea seed oil.

Description

technical field

[0001] The invention relates to an extraction process of oil, in particular to a supercritical extraction process of tea seed oil. Background technique

[0002] Supercritical fluid technology is a new type of separation technology. It uses supercritical fluid as an extraction agent to obtain separated components from fluid or solid materials under critical temperature and pressure conditions. Commonly used supercritical fluid extraction agents are CO 2 、CC l4 、CH 3 CC l3 , NH 3 、H 2 0, etc., the most widely used in the food industry is supercritical CO 2 extraction.

[0003] Supercritical C0 2 Fluid extraction technology is the use of C0 2 In the supercritical state, it has a high dissolving ability for the solute, but in the non-supercritical state, the dissolving ability for the solute is very low, so as to realize the extraction and separation of the target components. Supercritical C0 2 It has a certain solubility for substances with a molecula...
