What is Tea Extract Powder?

Tea Extract is the water or alcohol extract of tea leaves. It is rich in biologically active ingredients, including tea polyphenols, L-theanine, alkaloids, tea polysaccharides, tea saponins, vitamins, trace elements and mineral elements. It has the functions of delaying aging, inhibiting cardiovascular disease, preventing and treating cancer, refreshing the mind, regulating lipids and helping digestion. Clinically, it is commonly used for headache, dizziness, sleepiness, restlessness, thirst, food accumulation and phlegm stagnation, malaria, dysentery and other syndromes. Tea is a traditional Chinese drink. It is processed from the buds and leaves of the tea tree. Originated in my country. According to legend, more than 4,700 years ago, “Shen Nong tasted all kinds of herbs, encountered seventy-two poisons every day, and got tea (tea) to solve it” (“Shen Nong’s Materia Medica”). The ancient method of making tea is simple. More than 3,000 years ago, the drying method was used. The cake tea was made in the 3rd century AD, the fried and steamed green tea was created in the 8th century, and the black tea was invented in the 16th century. Tea-making technology from all countries in the world was introduced from China. It was introduced to Japan in the 9th century AD, and spread to Indonesia, India, Sri Lanka, Russia, etc. after the 19th century AD. The European custom of drinking tea was learned from China in the 16th century. The names of teas in various countries are also transliterated from Chinese. Ancient Chinese books have long recorded that drinking tea is beneficial.

Tea Extract Ingredients

Tea Extract contains hundreds of chemical components, among which the main ones are tea polyphenols, alkaloids, tea polysaccharides, tea pigments, vitamins, amino acids, mineral elements and so on. Tea polyphenol is a component that has been studied more, also called tea tannin and tea quality. It is a general term for polyphenols in tea and their derivatives. It is a light brown to white amorphous powder. Soluble in water, methanol, ethanol, ethyl acetate, glacial acetic acid, etc. Insoluble in benzene, chloroform, petroleum ether.

It is relatively stable under acidic conditions, and easy to oxidatively polymerize under alkaline conditions. Tea polyphenols are about a variety of compounds, mainly composed of four types of substances: catechins, flavonoids, anthocyanins and phenolic acids. Among them, catechins account for the total amount of tea polyphenols. There are mainly four kinds of catechins, epicatechin, epicatechin gallate, epigallocatechin, and epigallocatechin gallate, which have strong antioxidant activity and free radical scavenging ability. Studies have shown that the content of tea polyphenols must be within an appropriate range to meet the requirements of the concentration of green tea soup.

Tea Extract also contains alkaloids. Most of the alkaloids in tea are purine alkaloids, mainly caffeine, and contain a small amount of theobromine, theophylline and xanthine. Tea polysaccharide refers to complex heteropolysaccharide. There are mainly polysaccharides, lipopolysaccharides, combined polysaccharide glycoproteins, and proteins. It is composed of substances such as sugar, protein, pectin and ash in tea. Tea pigment is a mixture of polyphenols such as catechins and their oxidized derivatives in tea leaves, and the main components are theaflavins and thearubigins. Vitamins are a kind of physiologically active substances with low content and great effect. Tea also contains more vitamins. Since tea leaves are picked when they are young, they are rich in free amino acids. Among them, theanine, glutamic acid, aspartic acid and arginine have higher content, especially theanine has the highest content. Theanine in tea is easily soluble in water and has a positive effect on the aroma and umami of tea soup.

Tea Extract App

1. Whitening effect of Tea Extract

Tyrosinase is a key enzyme in melanin synthesis, and catechin can inhibit tyrosinase activity and affect melanin production. Using catechin as the effector to study its effects on the activities of potato tyrosinase, tyrosinase monophenolase and diphenolase, it was found that catechin can inhibit the active center of tyrosinase, resulting in a decrease in enzyme activity , and compete with the substrate L-dopa, reducing the efficiency of the enzymatic reaction. The tyrosinase inhibitory substances were screened from 10 traditional Korean tea extracts. The study found that green tea is the strongest tyrosinase inhibitor, and the main active ingredients are GCG, ECG and EGCG.

Black tea extract reduced melanin production by reducing the expression of protein tyrosinase and tyrosine-related proteins (TRP-1, TRP-2), while arbutin did not alter tyrosine protein levels. Oolong tea extract can reduce the transcription level of intracellular MITF, reduce the expression of tyrosinase, and significantly inhibit the phenomenon of melanosis. However, oolong tea extract could not inhibit mushroom tyrosinase activity in vitro. Tyrosinase is a special copper-containing glycoprotein in melanocytes, which is located on the melanosome, a unique organelle of melanocytes. The flavonoid component of tea has metal chelating ability. Tea contains a variety of antioxidant components, which have the ability to scavenge free radicals. The whitening effect of tea may be the combined effect of antioxidant effect and chelated metal ions.

2. Antibacterial effect of Tea Extract

The antibacterial mechanism may be because the main components in the tea extract can specifically coagulate bacterial proteins, destroy the bacterial cell membrane structure, etc., thereby inhibiting the growth of the test bacteria.

Pharmacological Effects of Tea Extract

1. Antioxidant impact
Tea polyphenols can straight scavenge energetic oxygen complimentary radicals. The tea polyphenols framework is rich in phenolic hydroxyl teams, which can supply energetic hydrogen to inactivate cost-free radicals, and the cost-free radicals formed by oxidation themselves have a fairly high catechol framework due to their catechol structure High security. Consequently, tea polyphenols are cost-free radical inhibitors for hydrogen-donating. Tea polyphenols can prevent lipid peroxidation, chelate steel ions, and turn on intracellular antioxidant protection systems.
2. Bactericidal and antibacterial, improve intestinal microbial structure.
Tea catechin substances have bactericidal and also inhibitory effects on many hazardous microbial varieties such as Staphylococcus aureus, Vibrio cholerae, and also Escherichia coli. Tea polyphenols have the effect of advertising the growth as well as spreading of several advantageous germs in the human digestive system, such as bifidobacteria, as well as these microorganisms can not only create lots of nutrients (such as B vitamins) in the digestive tract, however likewise inhibit the proliferation of dangerous microorganisms. 3. Antiviral effect
Tea catechins have repressive effects on flu viruses An and B; EGCG and also ECG, also at reduced focus of 0.01 to 0.02 mg/ml, have strong inhibitory impacts on HIV.
4. Minimize lipids as well as reduce weight, avoid and also treat atherosclerosis
Tea catechins, particularly EGCG, can prevent the synthesis of cholesterol in cells, and have the effect of reducing LDL cholesterol and also raising HDL cholesterol in the blood. The previous has the effect of promoting human atherosclerosis, while the latter has the impact of avoiding and boosting atherosclerosis.
5. Antihypertensive impact
Tea catechins, specifically ECG as well as EGCG, have noticeable inhibitory effects on angiotensin I transforming enzyme.
6. Tooth-healthy and anti-caries result
Research study in the late 1980s discovered that polyphenols in tea are one of the most crucial reliable substances for the anti-caries impact of tea.
7. Various other features
Tea Essence has hypoglycemic impact, in addition to anti-radiation result, anti-allergic impact, boosting immune function, stopping aging and more.

Preparation of Tea Extract

In the method for subcritical fluid extraction of Tea Extract, the tea leaves used are green tea, which specifically comprises the following steps:

1) Take 600g of tea leaves, at a temperature of 60°C and a pressure of 3MPa, control the material-liquid ratio of the tea leaves to the dimethyl ether subcritical fluid to be 1:1, and the flow rate of dimethyl ether to be 1kg/h. Continuous dynamic extraction of ether subcritical fluid for 30min to obtain extraction mixture;

2) The extraction mixture obtained in step 1) is enriched in a separation kettle, and the temperature is kept at 60° C. and the pressure is 1.2 MPa, and the dimethyl ether subcritical fluid is vaporized to obtain Tea Extract.

3) Collect and cool the gaseous dimethyl ether subcritical fluid obtained in step 2), and recycle the liquid dimethyl ether subcritical fluid obtained by condensation.

4) When the predetermined extraction time is reached, the extraction is terminated, the extraction kettle is closed and the vacuum is drawn to vaporize the dimethyl ether fluid in the extraction kettle. After condensation, it is returned to the storage tank for reuse, and then the tea raffinate is obtained.
