Problems solved by technology

But the ethanol concentration of the above-mentioned prior art usually needs to reach better extraction rate and purity at a higher level, and high-concentration ethanol can reduce the solubility of tea saponin, because tea saponin is insoluble in pure ethanol, and then reduces The yield of tea saponin; secondly, simply adopt ethanol solution, because the polarity of extractant is stronger, can make a large amount of impurity components (starch, polysaccharide, plant protein etc.) micro-leach in the extractant, thereby make tea saponin viscosity Large, dark in color, low in content and reduced in purity

Embodiment 1

[0025] The tea saponin extraction process in the camellia dregs of embodiment 1

[0026] Main reagents and raw materials in this embodiment: camellia seed; n-hexane (AR grade); ethanol (AR grade); methanol (AR grade); water (AR grade); dimethyl carbonate (AR grade).

[0027] The tea saponin extraction process in the camellia dregs of the present embodiment comprises the following steps:

[0028] S1. Pretreatment of camellia seeds: wash the camellia seeds, put them in a container, control the time, and crush them into fine particles;

[0029] S2. Degreasing: Weigh 50 g of dried camellia seeds that have been pulverized, put them in a 500 ml beaker, add 150 ml of n-hexane, stir for 2 hours to obtain camellia oil, collect and utilize the camellia oil, and dry the remaining ingredients to obtain camellia meal;

[0030] S3. Extraction of tea saponin: crush the dried camellia meal, put the crushed camellia meal into a conical flask, add 150-300ml of compound extraction solvent, extr...

Embodiment 2

[0033] The optimization of embodiment 2 composite extraction solvent proportioning

[0034] a) Optimization of compound extraction solvent components

[0035] The type of extraction solvent will have certain influence on the content and yield of tea saponin. Select different degreasing organic solvents (n-hexane, dimethyl carbonate) and extraction solvents (ethyl acetate, ethanol, chloroform, 50% ethanol water) and dimethyl carbonate in a ratio of 1:1 to compound, as in Example 1 Tea saponin was extracted according to the following steps, and the content and purity of tea saponin were determined by vanillin-concentrated sulfuric acid colorimetry (You Ruiyun, Zheng Shanyu, Chen Rong, et al. Research on the extraction process of tea saponin from longan tea dregs[J]. Applied Chemical Industry, 2015, 000(009):1635-1638.). The effects of different compound extraction solvents on the yield and purity of tea saponin were investigated.

[0036] The obtained tea saponin quality of t...

Embodiment 3

[0049] The optimization of embodiment 3 extraction temperature

[0050] The compound extraction solvent is dimethyl carbonate: 40% ethanol aqueous solution ratio of 1:1.8, extract tea saponin at different temperatures according to the steps of Example 1, and investigate the influence of temperature on the yield and purity of tea saponin.

[0051] The tea saponin quality obtained under the different temperature conditions of table 4

[0052]

[0053] Through a series of experiments, it can be seen that within a certain temperature range, as the temperature increases, the yield of tea saponin will increase, and the color will also deepen. However, as the temperature continues to increase, the yield of tea saponin will increase. Therefore, 60°C is the most suitable extraction temperature. Under this temperature condition, the quality of tea saponin is high.

Abstract

The invention discloses an extraction process of tea saponin in camellia seed meal, and application of the tea saponin in amino acid facial soap, and belongs to the technical field of tea saponin extraction. The extraction process comprises the following steps: S1, pretreating camellia seeds: cleaning and crushing camellia seeds; S2, degreasing: weighing the crushed and dried camellia seeds, and adding an organic solvent for degreasing treatment to obtain camellia seed meal; S3, extracting tea saponin: crushing the dried camellia seed meal, adding 150-300 ml of a composite extraction solvent,extracting for 1-3 h, and filtering to obtain dark red extract, wherein the composite extraction solvent is prepared from dimethyl carbonate and an ethanol-water solution in a volume ratio of 1:(1-3).Distribution is performed between the dimethyl carbonate and the ethanol-water solution by utilizing the polarity difference of different substances, so that components such as impurities are separated from the tea saponin, the impurity content of the tea saponin can be reduced by collecting the ethanol-water solution, and the effects of improving the product quality, improving the product yieldand purity and reducing the cost are achieved.

Description

technical field [0001] The invention relates to the technical field of tea saponin extraction, in particular to an extraction process of tea saponin in camellia dregs and its application in amino acid cleansing soap. Background technique [0002] Tea saponin is mainly derived from the hydroxyl group of the Theaceae plant. Among the various tissues and parts of camellia seeds, tea saponin combined with organic acids is a type of natural glycosides. It is combined with the carbonyl group on the ligand by a glycoside bond, and the sugar body part includes glucuronic acid, arabinose, and xylose. Tea saponin is a kind of natural nonionic surfactant. Since the molecular structure of tea saponin has both hydrophilic sugar body and hydrophobic group, it has excellent performance and is widely used in daily chemical, food, environmental protection and other fields. It is widely used and easy to be biodegraded without polluting the environment. [0003] Due to its wide range of uses...
