Cold tea healthier than open blisters
BREW tea in cold water, can not only make the release more of tea catechins,
caffeine can also be less. Ice-cold tea and cooling not only to quench their
thirst, but also healthier! Wants to bubble up drink cold black tea, step
more specific heat soak is also easy,

Cold tea benefits
Meditation tea, self-cultivation. Tea culture since ancient times is dominated
by hot water brewing. Modern experiments confirmed that the tea contains tannic
acid, catechin, vitamin c helps Health Canada components, offer SB which became
the health drinks. Young pop "cold tea" tea with cold water
immersion, subversion of the traditional cold drink. Many studies have found,
cold foam, allowing, tannic acid content, such as reducing caffeine,
phosphorus, are more secure.
Cold tea is the tea soaked in mild hypothermia in cold water for about 10
hours, let the fragrance of the tea and slowly release nutrients. Found, and
General compared to hot water to make tea, benefits of cold tea much, hot dahongpao tea
catechin, polyphenol stripping can be effective in the bubble, but caffeine,
tannin content is much lower.
The caffeine in teas, at high temperatures easily dissolved. Excess caffeine
cause rapid heart beat, loss of calcium, some cyclical phenomena such as
headache, insomnia, and will affect the absorption of calcium by the kidney
function. Cold tea release less caffeine, you can avoid this problem, reduce
the burden on gastric wall.
The tannic acid in tea (tannin) can prevent oxidation, promoting fat ferment
decomposition, reduce the chances of cardiovascular disease, but tannic acid
will combine with iron in the body, affecting the absorption of iron by the
body. If insufficient iron, oxygen supply on the wrong side, prone to iron

dissolve it, additional credits for health.
In addition, tannic acid are due to changes in tea baking process have
different, usually fermented more, contain fewer tannins, and drain more of
vitamin c, and unfermented green tea, high tannic acid content, more vitamin c.
Antioxidant effect of catechin have confirmed that when cold foam, free of
catechin (EC and the EGC) specific heat high tea tea. Overall, cold tie guan yin the
chemical components of tea will be increased with the soaking time, soaking
variation within two hours for most, but after a certain time, dissolved
content of change. Soak 8 hours later, apart from the caffeine content, and
remaining components is higher than the hot tea tea.
Cold tea antioxidant with soak time extended and enhanced, and reaching a
balance in 12 hours, her restored strength and hot tea are; ferrous ions chelating
1.08 times times the capacity for hot tea; DPPH free radical scavenging,
superoxide anion scavenging is comparable with hot tea.
Cold tea, has the characteristic of drink needed at any time, at any time, such
as travel, Office hours, unable to boil hot water, as long as the pure mineral
water, tea. Alternatively, you can save energy, such as electricity or gas.
