Problems solved by technology

However, due to its high alkalinity, long-term use will cause the hair to become hard, brittle and easy to break, and the process of preparing tea bran water is cumbersome
In addition, natural tea bran water shampoo has quietly risen again in various hair salons, but washing hair once is not only expensive, but also inconvenient to use and wastes time; tea bran resources are still not widely and commonly used, resulting in a waste of resources

Embodiment 1

[0030] The preparation method of tea bran extract comprises the following preparation steps:

[0031] 1) Get tea bran and pulverize to 50 mesh;

[0032] 2) Add an ethanol solution with a volume concentration of 6 times the weight of the tea bran to the pulverized tea bran and a volume concentration of 75%, and carry out high-pressure microjet ultrafine pulverization treatment at a pressure of 60 MPa and a temperature of 45° C., and the number of treatments is 2 times to obtain creamy slurry;

[0033] 3) Microwave extracting the creamy slurry for 20 minutes at a power of 450W to obtain a microwave extract;

[0034] 4) passing the microwave extract through a D101 macroporous resin chromatography column, eluting with an ethanol solution whose volume concentration is 70% three times the volume of the column, and collecting the eluate;

[0035] 5) Concentrate at 30°C and dry under reduced pressure at 55°C to obtain the desired tea bran extract.

Embodiment 2

[0037] The preparation method of tea bran extract comprises the following preparation steps:

[0038] 1) Get tea bran and pulverize to 80 orders;

[0039] 2) Add 8 times the weight of the tea bran to the pulverized tea bran in an ethanol solution with a volume concentration of 70%, and carry out high-pressure micro-jet ultrafine pulverization treatment at a pressure of 65 MPa and a temperature of 40°C. The number of treatments is 3 times to obtain creamy slurry;

[0040] 3) Microwave extracting the creamy slurry for 18 minutes at a power of 500W to obtain a microwave extract;

[0041] 4) passing the microwave extract through a D101 macroporous resin chromatography column, eluting with an ethanol solution whose volume concentration is 4 times the volume of the column and is 65%, and collecting the eluate;

[0042] 5) Concentrate at 32°C and dry under reduced pressure at 60°C to obtain the desired tea bran extract.

Embodiment 3

[0044] The preparation method of tea bran extract comprises the following preparation steps:

[0045] 1) Get tea bran and pulverize to 100 mesh;

[0046] 2) Add an ethanol solution with a volume concentration of 10 times the weight of the tea bran to the pulverized tea bran and a volume concentration of 65%, and carry out high-pressure microjet ultrafine pulverization treatment at a pressure of 70 MPa and a temperature of 45° C., and the number of treatments is 2 times to obtain creamy slurry;

[0047] 3) Microwave extracting the creamy slurry for 15 minutes at a power of 450W to obtain a microwave extract;

[0048] 4) passing the microwave extract through a D101 macroporous resin chromatography column, eluting with an ethanol solution having a volume concentration of 5 times the column volume and being 60%, and collecting the eluate;

[0049] 5) Concentrate at 35°C and dry under reduced pressure at 55°C to obtain the desired tea bran extract.

Abstract

The invention belongs to the technical field of preparation of plant extracts, and in particular relates to a tea bran extract, which contains 75-88% of tea saponin and 10-20% of tea oil by weight. The specific preparation method is: taking tea Bran pulverization, high-pressure microjet superfine pulverization treatment, microwave extraction, eluting through macroporous resin chromatography column, ethanol solution, collecting eluate, concentrating and drying to obtain the desired tea bran extract. The tea bran extract prepared by the method of the present invention will not cause hard hair, brittle hair, hair loss and other problems after long-term use, and is also suitable for people with dry hair without causing dry hair.

Description

technical field [0001] The invention belongs to the technical field of plant extract preparation, in particular to a tea bran extract and a preparation method thereof. Background technique [0002] Tea bran, also known as tea seed cake, is also known as tea dry, tea dregs, tea seed cake, tea seed powder, and bitter tea powder. It is purple-brown granule, which is the slag left after the wild camellia oil fruit is pressed. In addition to oil, water, protamine and refined fiber, the tea meal contains 12-18% tea saponin, 8.75% protein, and 6-9% oil. Our country has a wide range of tea tree planting and rich tea seed resources. Before the 1980s, due to the lack of materials, women in Guangdong and Guangxi areas often made tea bran water by soaking the residue cake left after tea seeds were squeezed into edible oil, that is, tea bran cake. Used to wash hair, the main components of tea bran water are tea saponin and tea oil, which have the functions of removing hair oil, treatin...
