Embodiment

[0022] A refining process of tea oil for cosmetics includes the following steps:

[0023] (1) Degumming

[0024] Heat tea seed crude oil to 80°C, add 30% citric acid with a concentration of 0.3% by weight of the oil, stir for 15 minutes, then add an 8% concentration of edible soda ash solution, adjust the pH to 5.5, continue to stir and heat until When the oil temperature rises to 90℃, add 30% citric acid with a concentration of 0.15% by weight of the oil and 3% edible salt water at the same temperature. Stir slowly for 30 minutes. When the temperature drops to 45℃, use PES with a molecular weight cut off of 30,000. Membrane ultrafiltration crude oil, the pressure is 0.2MPa, the filtrate is centrifuged to obtain degummed oil;

[0025] (2) Alkali refining and deacidification

[0026] Heat the degummed oil to 75℃, and prepare 10-14Be by detecting the acid value of the crude oil as 3 。 Lye, quickly and uniformly inject the prepared lye into the oil, stir at 80r / min, and mix thoroughly. ...

Abstract

The invention discloses a refining process for cosmetic camellia oil. The process includes the following five steps: degumming, alkali refining deacidification, adsorption decolorization, vacuum deodorization and fractionation. According to the invention, organic membrane technical treatment is added to the degumming process to further reduce the content of phospholipid, FFA and pigment in the camellia oil and greatly improve the color of the camellia oil, thus reaching the purpose of pre-decolorization. In order to reduce the burden of decolorization, also the acid value of crude oil can be further reduced. The alkali consumption in the deacidification process can be reduced, so that the product yield can be improved. By means of activated clay, the adsorption performance can be improved, and under a heating circumstance, pigments and other impurities in oil can be effectively adsorbed and removed. The camellia oil is almost colorless under observation by naked eyes, thus already meeting the requirements for cosmetic oil.

Description

Technical field [0001] The invention relates to a refining process of tea oil for cosmetics, belonging to the technical field of oil processing. Background technique [0002] Camellia oil is an oil extracted from Camellia oleifera seeds. Its main component is glycerides rich in oleic acid, with an oleic acid content of 74-87%. The physical and chemical properties of tea oil are very similar to olive oil. The fatty acid composition and triglyceride structure of tea oil are essentially the same as olive oil. Compared with olive oil, tea oil contains less unsaponifiable matter. Tea oil is an excellent nutritious and health oil. At present, tea oil is mainly edible in my country, but it is still blank to refine tea oil for cosmetics. [0003] Cosmetics mostly use oil as the base grease, and the deterioration and oxidation of oil are the main problems in the production process. The tea oil is a natural vegetable oil that is difficult to oxidize and deteriorate, and it can suppress th...
