'real green teabag' by hyung gyun jung, il seop so, han bi jung and jae young heo
'green tea's main incredient is catechins. it is safe and stable when in between 60 to 70 degrees celsius. however, if it is heated to a higher temperature and brewed longer, another substance called tannin is released. tannin is easily combined with catechins as well as other essential substances in our body such as calcium and iron. as a result, tannin prevents our body from absorbing those substances. therefore, the temperature should be checked properly to truly appreciate the taste of green tea. the best way to drink green tea is when the tea bag is removed after letting it steep for 2 minutes at a temperature of 80 to 90 degrees celsius. 'real green teabag' is made from natural green tea leaves so that it can decompose easily. the wrapping does not consist of more than one part so that it can be opened as if it is a folded green tea leaf. in other words, no trees need to be cut down in order to make clean white wrapping paper. the product appeals to our emotions by using leftover green tea leaves after brewing tea.'
