摘要:
A process for selectively removing caffeine from a caffeine-containing catechin composition, which includes dissolving the caffeine-containing catechin composition in a 9/1 to 1/9 by weight mixed solution of an organic solvent and water, and then bringing the resultant solution into contact with activated carbon alone or with activated carbon and also acid clay or activated clay; and a packaged beverage containing such a decaffeinated composition.
摘要:
Provided is a packaged beverage comprising the following ingredients (A) and (B): (A) non-polymer catechins in an amount of from 0.092 to 0.5 g/100 mL beverage, (B) an alcoholic precipitate in an amount of 0.015 g/100 mL beverage or less in terms of the amount of magnesium, at a weight ratio (A)/(B) ranging from 30/1 to 50000/1. The packaged beverage of the present invention is the best suited beverage for health promotion, because drinking of it permits transfer of a large amount of catechins to the blood form the beverage and their absorption in the body is excellent.

摘要:
Provided is a packaged beverage, which comprises, in the dissolved form, catechins composed of the following non-polymer component (A) and another non-polymer component (B): (A) non-epi-catechins, (b) epi-catechins, and has, per 500 mL of the packaged beverage, said components in amounts satisfying the following equations: (A)+(B)=460 to 2500 mg (i) (A)=160 to 2250 mg (ii) (A)/(B)=0.54 to 9.0. (iii) The packaged beverages of the present invention are excellent in stability of color tone and transparent appearance even after long-term storage, have smooth feeling in the throat upon drinking, and have good palatability; and in addition, have PPAR-dependent gene transcription activating effects which are safe and effective for prevention and alleviation of obesity.
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.
