　　What are the benefits of cold tea

Tea meditation, self-cultivation. Since ancient times, tea culture are based on hot water, brew the main. Modern experiments confirmed that the tea contains tannic acid, catechin, vitamin C and other ingredients to help health, extra points, so that tea became health drinks. The hip young people of the "cold tea" to cold water immersion of tea, to subvert the traditions cold thirst-quenching. Many studies have found that the cold bubble approach allows caffeine, phosphorus, tannic acid was reduced, on health more secure.

Cold tea is to tea, soak in cold water at low temperatures of about 10 hours, so that the fragrance of tea and slowly release nutrients. It was found, and general hot tea compared to the benefits of cold tea and much more, the original hot tea in the catechin, polyphenols can be an effective amount of dissolved bubbles out, but the caffeine, tannic acid content are low more.

The caffeine in tea, be easily dissolved at high temperatures. Excessive caffeine cause rapid heart beat, calcium loss, some people will be cyclical headaches, insomnia and other phenomena, and will affect the renal calcium absorption. Cold tea caffeine released from the lower to avoid this problem, reduce the burden on the stomach.

The tannic acid in tea (tannic acid) can prevent oxidation, the promotion of enzymes break down fat and reduce risk of cardiovascular disease, but the tannins combine with the body's iron affect the body's iron absorption. If iron deficiency, oxygen supply to the poor, could easily lead to iron-deficiency anemia, so that spirit is not easy to concentrate, memory will be a recession. The way with cold foam, tea still retains the sweetness, but the tannic acid and caffeine, are more difficult to dissolve out extra points for health.

In addition, tannic acid, a result of the tea baking process has different changes, usually the higher the degree of fermentation, which contain fewer tannins, and vitamin C which also lost more without unfermented green tea, tannic acid relatively high content of vitamin C is greater.

Antioxidant effect of catechins has long been confirmed, cold soak, the free-type catechins (EC, EGC) high tea than hot tea. On the whole, cold tea and tea with the chemical composition of content will increase the growth of immersion time, within two hours of soaking the largest volume changes, but some time after the dissolution of the amount of little change. 8 hours after immersion, in addition to caffeine, the rest of the components is higher than the hot tea tea.

The oxidation resistance of cold tea with the extension of immersion time increased, but after 12 hours closer to balance, reducing power and heat their tea quite; ferrous ion chelating capacity of hot tea and a 1.08-fold; DPPH free radical scavenging ability, superoxide anion scavenging capacity and hot tea is quite.

But not every bubble tea are suitable for cold tea brought in general, the longer the fermentation time, tea in the phosphorus content was relatively higher, cold tea should try to choose low-phosphorus low-fermented tea. The most common items for the tea, green tea, fermentation is lower, followed by oolong tea, fermentation is the high level of black tea, Tie Guan Yin, Pu'er tea.
