[What is green tea extract]

Green tea is the second largest beverage demanded by consumers worldwide. Used in China and India for its medicinal effects. There are several compounds extracted from green tea including catechins which contain an enormous amount of hydroxyphenols that are easily oxidized, congregated and contracted, which explains its good anti-oxidation effect. Its anti-oxidation effect is 25-100 times as strong as those of vitamin C and E.

It is widely used in medicines, agriculture, and chemical and food industries. This extract prevents cardio-vascular disease, lowers the risk of cancer, and decreases blood sugar and blood pressure, as well as viruses. In the food industry, the anti-oxidation agent used for preserving food and cooking oils.

[Function]

1. Green tea extract can reduce blood pressure, blood sugar, blood lipids.

2. Green tea extract has the function of removing radicals and anti-aging.

3. Green tea extract can enhance the immune function and prevention of colds.

4. Green tea extract will anti-radiation,anti-cancer, inhibiting the increasing of cancer cell.

5. Green tea extract used to anti-bacterium, with the function of sterilization and deodorization.

[Application]

1.Applied in cosmetics field, Green tea extract owns the effect of anti-wrinkle and anti-Aging.

2.Applied in food field, Green tea extract is used as natural antioxidant, antistaling agent, and anti-fading agents.

3.Applied in pharmaceutical field, Green tea extract is used to prevent and cure cardiovascular disease, diabetes.

Culture: The propagation of microorganisms using various media ,Culture media Used to grow bacteria
Can be used to: Enrich the numbers of bacteria
Select for certain bacteria and suppress others Differentiate among different kinds of bacteria ,Culture and Medium Culture is the term given to microorganisms that are cultivated in the lab for the purpose of identifying and studying them.
Medium is the term given to the combination of ingredients that will support the growth and cultivation of microorganisms by providing all the essential nutrients required for the growth (that is, multiplication) in order to cultivate these microorganisms in large numbers to study them. ,Specific Media Defined media are media composed of pure ingredients in carefully measured concentrations dissolved in double distilled water i.e., the exact chemical composition of the medium is known. Typically, they contain a simple sugar as the carbon and energy source, an inorganic nitrogen source, various mineral salts and if necessary growth factors (purified amino acids, vitamins, purines and pyrimidines
,Need for Culture Media It is usually essential to obtain a culture by grwoing the organism in an artificial medium.
If more than one species or type of organism are present each requires to be carefully separated or isolated in pure culture. Several organism need the determination of Antibiotic sensitivity pattern for optimal antibiotic selection ,Basic requirements of culture media Nutrients – Energy source – Carbon source – Nitrogen source Mineral salts – Sulphate, phosphates, chlorides & carbonates of K, Mg & Ca. A suitable pH – 7.2 – 7.4 Accessory growth factors – Tryptophan for Salmonella typhi – X & V factors for H. influenzae
