PROBLEM TO BE SOLVED: To provide a new manufacturing method of tea bags which, regarding the tea bags with a powdered tea made by adding the powdered tea to a pulverized tea, can stably get the color of water in spite of hardness of the extracted water, and furthermore stably and evenly get the very fragrance of a green tea.SOLUTION: The tea bag manufacturing method is characterized as such that it pulverizes a pulverized tea raw material tea leaves (hereinafter referred to as "pulverized tea raw material tea leaves") in which the ratio (A1/B1×1000) of a theanine quantity (A1) against a fiber amount (B1) is 10 to 25, obtains the pulverized tea in which a loose bulk density is 190 ml/100 g to 350 ml/100 g, and contains the pulverized tea together with a powdered tea having a maximum particle diameter (Dmax) of 350 μm corresponding to 1 to 10 mass% of the pulverize tea in a bag body made of filters with water conduction of 2.0 to 4.7 seconds.SELECTED DRAWING: NoneCOPYRIGHT: (C)2019,JPO&INPIT【課題】粉砕茶に粉末茶を添加した粉末茶入りのティーバッグに関して、抽出する水の硬度にかかわらず、水色をぶれなく安定して得ることができ、さらには緑茶らしい香味をぶれなく安定して得ることができる、新たなティーバッグの製造方法を提供する。【解決手段】繊維量(B1)に対するテアニン量(A1)の比率(A1/B1×1000)が10~25である粉砕茶の原料茶葉(以下「粉砕茶原料茶葉」と称する)を粉砕して、ゆるみカサ密度が190ml/100g~350ml/100gである粉砕茶を得、当該粉砕茶とともに、当該粉砕茶の1~10質量%に相当する最大粒径(Dmax)350μm以下の粉末茶を、通水度が2.0~4.7秒であるフィルターからなるバッグ本体に収納することを特徴とするティーバッグの製造方法を提案する。【選択図】 なし
