摘要:
This invention relates to a process for producing a green tea flavor by extracting it from green tea leaves with water cooler than 10° C., and also to a beverage with the flavor obtained by the process and added therein. This invention also relates to a process for producing a dried green tea polyphenol by subjecting green tea leaves to a first extraction with water cooler than 10° C. and then to a second extraction with warm water of 50° C. or higher, and drying an extract of the second extraction, and also with a process for producing a beverage by adding a green tea polyphenol obtained by the process.

摘要:
A packaged green tea beverage, wherein (A) the packaged green tea beverage contains from 0.08 to 0.5 wt % of non-polymer catechins, (B) a percentage of non-epicatechin body in the non-polymer catechins is from 5 to 25 wt %, (C) a percentage of gallate body in the non-polymer catechins is from 5 to 95 wt %, (D) pH is from 2.5 to 5.1, and (F) the packaged green tea beverage contains from 0.0001 to 20 wt % of at least one sweetener selected from fructose, glucose, sucrose, fructoglucose syrup and glucofructose syrup. A packaged green tea beverage containing non-polymer catechins in high concentration can be provided, which can not only reduce astringency but also provides for adequate sweetness and sourness without impairment of the taste and is suited for long-term storage while containing a sweetener.

By mixing an amino acid in a packed beverage containing non-polymer catechins in high concentration, the physiological effects of the catechins are manifested and the intake of the amino acid is facilitated. A packaged beverage containing: (A) from 0.06 to 0.5% by mass of non-polymer catechins; (B) from 0.01 to 5.0% by mass of at least one amino acid selected from L-isoleucine, L-leucine, L-valine, L-threonine, DL-methionine, L-methionine, L-histidine, L-phenylalanine, L-lysine, L-tryptophan, L-aspartic acid, L-glutamic acid, L-alanine, DL-alanine, glycine, L-asparagine, L-glutamine, L-arginine, L-serine, L-tyrosine, L-cystine and L-proline, or a salt thereof; and (C) from 0.0001 to 20% by mass of a sweetener, wherein (G) a percentage of gallate bodies in the non-polymer catechins is from 5 to 55% by mass, and pH is from 2.5 to 5.1.
摘要:
A concentrated beverage composition for reconstitution is reduced in bitterness and astringency, adequate in both sweetness and sourness and improved in storage stability despite the inclusion of a high concentration of non-polymer catechins. The concentrated beverage composition for reconstitution contains (A) from 0.5 to 25.0 wt % of non-polymer catechins, (B) a carbohydrate, and (C) a hydroxycarboxylic acid, and meets the following conditions (D) and (E) as well as at least one condition selected from the following conditions (F1), (F2) and (F3): (D) a content of gallic acid is lower than 0.6 wt %, (E) a percentage of non-epi-forms in the non-polymer catechins is from 5 to 25 wt %, (F1) a Brix degree is from 20 to 70, and when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %, a pH is from 2.5 to 6.0, (F2) a solid content is not lower than 70.0 wt %, and when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %, a pH is from 2.5 to 6.0, and (F3) an absorbance at 400 nm is smaller than 0.5 and a pH is from 2.5 to 6.0, when diluted with deionized water to give a non-polymer catechin concentration of 0.13 wt %.
