Extraction method of tea polyphenol and Persian safflower after fat dissolution and skin moistening oil thereof

Abstract

The invention discloses an extraction method of tea polyphenol and Persian safflower after fat dissolution and skin moistening oil thereof, and belongs to the technical field of essential oils. The extraction method comprises the following steps: (1) preparing vegetable oil according to a certain proportion for later use; (2) grinding and crushing common low-EGCG-content tea polyphenol and Persian safflower, then putting into a stirrer, and then adding the standby vegetable oil; (3) starting a stirrer, carrying out low-speed stirring in a low-temperature environment, and then carrying out condensation extraction; and (4) filtering, precipitating and filtering with a molecular film to obtain a finished product. According to the extraction method of the tea polyphenol and the Persian safflower after fat dissolution, which is disclosed by the invention, the volatilization loss of tea polyphenol inclusions can be reduced, and the recovery rate and the EGCG content in the tea polyphenol are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of essential oils, in particular to an extraction method after fat-dissolving tea polyphenols and Persian safflower and its moisturizing oil. Background technique [0002] With the improvement of people's living standards and the strengthening of skin care awareness, the use of emollient essential oils is becoming more and more extensive, such as skin care oils containing tea polyphenols. [0003] The main beneficial ingredient in tea polyphenols is EGCG. However, the content of monomeric EGCG in tea polyphenols purchased in the common traditional way in the market is relatively low, generally between 10% and 40%. Adding this kind of tea polyphenols with low monomer content will greatly affect the effect of emollient essential oil, and also bring in more unnecessary impurities, making the effect of emollient essential oil not good. Although there are currently various methods for extracting high-content EGC...

[0003] The main beneficial ingredient in tea polyphenols is EGCG. However, the content of monomeric EGCG in tea polyphenols purchased in the common traditional way in the market is relatively low, generally between 10% and 40%. Adding this kind of tea polyphenols with low monomer content will greatly affect the effect of emollient essential oil, and also bring in more unnecessary impurities, making the effect of emollient essential oil not good

Although there are currently various methods for extracting high-content EGCG tea polyphenols, the existing methods not only require a lot of equipment and instruments, but also are relatively precise, expensive, and costly. The temperature is relatively high and the saturation in the oil is low, resulting in a large amount of volatilization of the content of tea polyphenols, resulting in a relatively low recovery rate of extraction, a waste of more raw materials, and more energy consumption, which also makes Major manufacturers are distressed

[0004] In addition, the current shelf life of skin care essential oils extracted from plants is relatively short, and many of them are ready-to-use, which is quite inconvenient to use, or a large number of preservatives and other ingredients are added to extend the shelf life, which will undoubtedly increase the burden on the skin and affect the skin. The absorption of skin care oil greatly reduces the effect of skin care
