온음료자판기는 그동안 커피 일색이었다. 국산차 판매도 일부 있지만 낮은 품질수준과 위생문제로 소비자의 미각을 사로잡기는 역부족이었다. 마치 커피자판기만 존재하는 것 같은 분위기. 그러나 어디 마실 만한 차가 커피만 있으랴?. 홍차, 녹차 같은 대중성 높은 차들도 있다. 과거만 해도 국내에서는 이들 차를 자판기로 판매하기 위한 도전이 없었다. 웰빙 차 시장이 고객 선호도 증가와 함께 시장이 커지고 있는데도 대응을 못해 왔던 것이다. 그런데 최근 녹차를 판매하는 자판기 보급이 확대되고 있다. 하동녹차연구소가 하동녹차의 보급 확대를 위해 선보인 액상녹차자판기가 큰 주목을 받고 있다.

This study was carried out to investigate the chemical composition and the inorganic constituents of the green tea at the 3 picking periods (Ujeon, Sejag, Jungjag) in Hadong. The results as follows ; The contents of chlorophyll, tannin, vitamin-c and total catechin were increased as picking periods increased but the contents of total nitrogen, total free amino acids, theanine and caffeine were decreased on the reverse. The inorganic constituents Mg, Ca and Mn were increased as picking periods getting late but the Na, K, B contents were decreased on the reverse. The contents of the total nitrogen, chlorophyll, total free amino acid, theanine, caffeine and total catechin and Na, Mg, Ca, B and Se were insignificant differences between Ujeon and Sejag.

This study used HPLC to analyze the contents of catechins, alkaloids, theanine, total phenolic compounds and antioxidant activities of commercial Hadong green tea leaves(Uzen, Sezak, Jungzak, Daezak). The content of catechins, alkaloids, theanine, total phenolic compounds were lower by water extracts than by 80% ethanol-water extracts. Total catechin and alkaloid contents in Uzen(172.33 mg/g, 30.80 mg/g) by 80% ethanol extract were the highest. Theanine contents of 80% ethanol-water extracts ranged form 55.36 to 37.48 mg/g of tea leaves. Total phenloic compounds contents of green tea were higher than Uzen. Antioxidative of green tea by DPPH, FTC, TBA method were higher than that Uzen.
