Refining process of tea seed oil and application of tea seed oil in healthcare oil

Abstract

The invention discloses a refining process of tea seed oil. The process includes the following steps of firstly, selecting plump tea seeds free of mildew, spots and plant diseases and insect pests, husking the seeds through a husking machine to obtain tea seed kernels, and sending the tea seed kernels into an oven to be dried for 35-45 minutes at the drying temperature of 65-75 DEG C. According tothe refining process of the tea seed oil, a solvent extraction method and a supercritical CO2 fluid extraction method are used in cooperation; a solvent is added for extraction, waste generated afterextraction is extracted 1-2 times through the supercritical CO2 fluid extraction method, extraction solutions are mixed, and then the extraction solution and crude tea seed oil continue to be extracted; by means of the operation method, the oil yield is improved, meanwhile n-hexane is effectively removed through the extraction temperature in the extraction process, and the purity of the tea seedoil is improved.

Description

technical field [0001] The invention relates to the technical field of tea seed oil refining and application, in particular to a tea seed oil refining process and its application in health care oil. Background technique [0002] Tea seed oil is also known as camellia oil, tea pear oil; camellia is a special product in China's Dabie Mountains, Fujian, Jiangxi, Hunan and other places. High-quality camellia oil can be extracted from the fruit, that is, tea seed oil. Method 1: Squeeze, from the camellia tree Seeds, the production process of tea seed oil can be divided into: oil pressing, filtration, method two: subcritical extraction, subcritical low temperature extraction technology is tea seeds (water content 10-15%) shelling, crushing, rolling, subcritical extraction Extracted at low temperature and refined, the finished camellia seed oil is obtained. The unsaturated fatty acid in camellia oleifera seed oil reaches more than 90%, oleic acid reaches 80-83%, linoleic acid reach...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the extraction methods of tea seed oil mostly adopt hot pressing, cold pressing, supercritical CO 2 Fluid extraction method, etc., tea seed oil prepared by different extraction methods has different flavor and mouthfeel. oil, peanut oil and pumpkin seed oil, wherein the weight percentage of each component is: tea seed oil 50%-70%, sesame oil 9%-15%, walnut oil 6%-10%, peanut oil 12%-20%, pumpkin The tea seed oil is 2% to 5%, wherein the tea seed oil is obtained by an aqueous enzyme process, and the tea seed oil of this invention is prepared by an aqueous enzymatic method, and there are tea saponin and concentrated protein in the tea seed oil extraction process, resulting in poor demulsification effect , and then the oil yield drops. In addition, health care oil uses a variety of oils to compound, and sesame oil has a strong fragrance, which covers the fragrance of other oils, resulting in a decline in flavor and taste, which limits the technological development of tea seed oil.
