The present invention provides a new manufacturing method of containered green tea beverage suited for selling hot. A step of eliminating silica was introduced in the manufacturing process, wherein the silica is eliminated after adding silica to a tea extract obtained by extracting green tea leaves to adsorb the sediment component present in tea extract to the silica. By adding silica to the tea extract and bringing them into contact, the proteins and polysaccharides causing secondary sediment can be selectively adsorbed and decreased, allowing the occurrence of sediment to be prevented, even when selling the beverage hot. Furthermore, it allows a large amount of flavor component to be left. Furthermore, a large amount of catechins can be left in the beverage, allowing the growth of heat-resistant bacteria to be inhibited by the antibacterial action of catechins. In addition, fatty acid oxidative decomposition products, which are the causes of degraded odor, can be selectively decreased, while on the other hand, roast aroma components, such as pyrazine, can be left in large amounts.本發明係提供了一種適合加熱販售的容器裝綠茶飲料的新製造方法。在製造步驟中加入了將矽石添加於萃取綠茶葉所得的茶萃取液中，而將茶萃取液中的沈澱物成份吸附至該矽石，之後，除去該矽石之步驟。於茶萃取液中加入矽石，並使其接觸，可使二次沈澱物的原因物質之蛋白質和多醣類被選擇性地被吸收而降低，甚至於加熱販售時也可防止沈澱物的產生。而且，這使的風味成份大量得到保留，又可使兒茶素大量保留在飲料中，藉由兒茶素的抗菌作用，可抑制抗熱細菌的生長。另外，可選擇性地減少作為產生惡化氣味原因的脂肪酸氧化分解產物，另一方面，吡嗪等之烘焙香味成份可大量得到保留。
