Problems solved by technology

The three have many disadvantages: (1) The high-temperature steaming and frying process of the pressing method is easy to introduce trans fatty acids and carcinogenic benzopyrene, the initial residue oil has many impurities, and the post-processing procedure is complicated
(2) The cold pressing method avoids the influence of high-temperature steaming and frying process, but the extraction rate of tea oil is low, the amount of residual oil in tea meal is large, and the post-processing is complicated
(3) The efficiency of the solvent method is low, the solvent loss is large, and there are solvent residues, which seriously affect the quality of camellia oil
(4) The obtained crude oil has to undergo degumming, deacidification, decolorization, deodorization, dewaxing, desolventization and winterization treatment. The operation cycle is long, the yield is low, the loss of nutrients is large, and a large amount of waste water and waste residues are produced.
Zeng Hongyan (using GC-MS to analyze the fatty acids of tea oil extracted by different methods, Journal of Tropical and Subtropical Botany, Volume 13, Issue 3, 2005) compared the composition of fatty acids in tea oil with different extraction methods, and believed that supercritical carbon dioxide extraction is the best way to extract tea oil method, but neither the extraction process was further optimized nor the content of active ingredients in the oil was determined

Abstract

The invention discloses an extracting composition of camellia. The extracting composition of the camellia comprises the following components in parts by mass: 15 to 25 parts of palmitic acid, 55 to 70 parts of oleic acid, 5 to 15 parts of a linoleic acid and linolenic acid mixture, 1.5 to 2.5 parts of squalene, 0.2 to 2.5 parts of beta-carotene and 0.5 to 1.5 parts of vitamin E, wherein the mass ratio of the linoleic acid to the linolenic acid is 6:1. The invention also discloses a preparation method of the extracting composition of the camellia. The preparation method comprises the following steps: (1) preparing camellia seed powder; (2) throwing the camellia seed powder into an extraction kettle, performing supercritical extraction and collecting extracts; (3) combining the extracts and performing liquid separation to obtain the extracting composition. The camellia extract provided by the invention has the advantages of clear natural components, high content of active components, zero solvent residue and stable quality; the method provided by the invention simplifies the flow, is high in yield and short in production period and is suitable for large-scale production; carbon dioxide is recycled, environmental pollution is avoided, and industrial 'three wastes' are avoided.

Description

technical field [0001] The invention relates to the technical field of camellia extraction, in particular to an extraction composition of camellia and a preparation method thereof. Background technique [0002] Camellia oleifera Abel is an important woody oil-bearing tree species endemic to my country. Camellia oil prepared from camellia seeds has been widely consumed as a dual-effect edible oil. Camellia oil is rich in unsaturated fatty acids, its composition and ratio are similar to olive oil, and it is known as "Oriental olive oil" and "treasure in oil". Camellia seeds in their natural growth state are hardly polluted by pesticides and fertilizers. It does not contain carcinogenic aflatoxin and erucic acid and gossypol which are harmful to the human body, and is a green and healthy food. "Compendium of Materia Medica" records: "Tea oil is cool in nature, has the effects of cooling blood, stopping bleeding, clearing away heat, and detoxifying. According to the "Chinese ...
