The present invention provides a technique for producing a tea wherein water-insoluble components of tea leaves have been made soluble in water and the natural umami components inherent to tea leaves have been increased. It also provides a technique for manufacturing a tea-based alcoholic drink which has “tea leaf-origin aroma”, “umami and body” and “mild alcoholic aftertaste” in a good balance. Tea leaves are processed with an extruder at a temperature of 80 to 150° C. and under a pressure of 0.2 to 30 MPa for 5 to 600 sec while supplying 1 to 100 parts by weight, per 100 parts by weight of the tea leaves, of water or an aqueous sugar solution, Thus, a processed tea leaf product is stably produced while avoiding blowout from the outlet. A tea extracted from this processed tea leaf product shows a significantly improved taste.

Thus, a processed tea leaf product is stably produced while avoiding blowout from the outlet. A tea extracted from this processed tea leaf product shows a significantly improved taste compared with one extracted from unprocessed tea leaves. Further, a tea-based alcoholic drink having a significantly improved taste can be produced by extracting a starting material, wherein the weight ratio of the processed tea leaf product as described above:tea leaves (b) is 1:9 to 1:0, with a solvent containing 5 to 80% by weight of an alcohol to give a tea extract.
摘要:

The present invention relates to a starch-containing tea beverage. More specifically, the present invention relates to a cereal tea beverage containing starch at a content of 0.009% by weight or more, which has an appropriate roasted aroma and mildness peculiar to cereal tea, relieves the pasty texture originating from the starch, and thereby has an improved taste and flavor, as a result of addition of ultrafine ground tea leaves having an average particle size of 1 μm or less. The present invention also relates to a process for producing such a cereal tea beverage, and a method for improving the taste and flavor of such a cereal tea beverage.
摘要:
The present invention provides an agent for improving taste of tea drinks, comprising at least one glyceroglycolipid, preferably monogalactosyl diacylglycerol or digalactosyl diacylglycerol, as an active ingredient. The agent of the present invention is for use to enhance kokumi, to mask astringent taste, and to prevent precipitates. The agent of the present invention is effective especially in improving tea drinks containing ground tea leaves. The present invention also provides a method for producing tea drinks containing ground tea leaves and at least 1.0 μg/ml of glyceroglycolipids and having an absorbency of 0.25 or below at 680 nm, and tea drinks containing glyceroglycolipid, which method comprises grinding tea leaves into an average particle size of 1-100 μm (preferably 1-50 μm, more preferably 1-20 μm), and mixing the resulting ground tea leaves with neutral (pH 5-7, preferably 5.5-7, especially preferably 6-7) water to elute the glyceroglycolipids into the water.
