Problems solved by technology

There are many degumming methods at present, including hydration degumming, acid degumming, special degumming, enzymatic degumming, etc. Enzymatic degumming can remove phospholipids very well, but the enzyme reaction time is long, and the degumming takes a long time, which needs further optimization
At the same time, in the existing decolorization process, clay is mainly used as a decolorizing agent, and a large amount of clay is required to have a good decolorization effect, but excessive use of clay will cause the acid value and peroxide value of oleic acid to rise, and accelerate oil oxidation and back to color , and the decolorized oil has an earthy smell, which makes deodorization difficult, so the decolorization method needs to be further optimized

Abstract

The invention discloses a method for refining tea oil for cosmetics, and relates to the field of technologies for processing oil. The method for refining the tea oil includes five steps of degumming, deacidifying, decoloring, deodorizing and fractionating. Enzyme activators such as calcium dihydrogen phosphate, potassium chloride and ferrous sulfate are added at the step of degumming and are combined with ultrasonic treatment to assist in degumming; decoloring is carried out by the aid of modified activated carbon and activated clay jointly at the step of decoloring. The method for refining the tea oil has the advantages that degumming and decoloring processes are further optimized, so that the degumming time can be shortened, the quality of decolored oil can be improved, the tea oil obtained by the aid of the method is colorless and odorless and is high in stability, oxidation and color reversion of the tea oil can be prevented, and requirements on oil for the cosmetics can be met.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of oil processing, in particular to a method for refining camellia oil for cosmetics. [0003] 【Background technique】 [0004] The main component of camellia oil is oleic acid glyceride, and is rich in bioactive ingredients such as vitamin E, camellia saponin, tea polyphenols, zirol and squalene, and has the same nutritional and health effects as olive oil. The oleic acid in tea oil is the same as the oleic acid in human skin, and has good moisturizing effect; the biophenols, carotenoids and other components in tea oil can remove free radicals in the human body, have the effect of anti-oxidation and prevent skin aging; Tea oil also has a strong UV absorption function. Therefore, tea oil has good moisturizing, anti-aging and sunscreen effects, and is non-toxic, non-irritating, strong in stability, and can be used as a high-grade skin care product. At present, the processing of camellia oil in my cou...
