영문 초록

Non-fermented steaming tea and semi-fermented rolling tea were processed with leaves of Castanea crenata, which used as a folk medicine for the treatment of allergic diseases such as lacquer poisoning and whooping cough to develope them as a tea. The processed tea was packed by tea bag and aluminium pack, and subjected to storage stability, such as color difference of extract, content of vitamin C and anti-allergic effect for 12 month at 4˚C, 35˚C, respectively. Color stability of each water extract was analyzed by Hunter's value. There was no significant color difference between the tea packed by tea bag and aluminium pack. Vitamin C content of non-fermented steaming tea was approximately 1.24mg%, it gradually decreased for 3 month, where as not detected in semi-fermented rolling tea. Anti-allergic effects of Castanea crenata leaf tea were asessed by testing their effects on the degranulation of mast cells. For this, hexosaminidase release from RBL-2H3 cells was used. At the concentration of 300 ㎛/㎖ of the water extract, the degranulation of RBL-2H3 cells were inhibited 50.4% and 35.4% by non-fermented steaming tea and semi-fermented rolling tea, respectively. There was no significant difference by packing and storage methods for 12 month.
