PROBLEM TO BE SOLVED: To provide a smoothly going down bottled or canned tea beverage that contains a high concentration of tea-originated grains, but provides little feeling of coarse particles in being drunk, tastes pleasant and goes down refreshingly.SOLUTION: The invention is for producing and providing a bottled or canned tea beverage containing a high concentration of tea-originated grains in which the turbidity (OD680) represented as absorbance at 680 nm is adjusted to 0.5 or more, where the theanine concentration is adjusted to 50-2000 ppm and/or the glutamic acid concentration is adjusted to 10-1000 ppm thereby providing little feeling of coarse particles in being drunk, tasting pleasant and going down refreshingly, and thus realizing a smoothly going down high-concentration tea-originated grain-containing bottled or canned tea beverage.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】茶由来粒子を高濃度に含有するにもかかわらず、飲用時にざらつきを感じにくく、口当たりの良いすっきりしたのどごしを有する、のどごし感に優れた容器詰めの茶飲料を提供すること。【解決手段】680nmにおける吸光度として表わされる濁度(OD680)が、0.5以上に調整された茶由来粒子を高濃度に含有した容器詰め茶飲料において、テアニン濃度を50~2000ppm及び/又はグルタミン酸濃度を10~1000ppmにそれぞれ調整することで、飲用時にざらつきを感じにくく、口当たりの良いすっきりしたのどごしを有する、のどごし感に優れた茶由来粒子高濃度含有容器詰め茶飲料を製造し、提供する。【選択図】なし
