摘要:
The present invention describes new compositions of matter comprising (1) roasted coffee beans in either whole bean form or in ground form to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added, (2) liquid beverages extracted at a pressure of less than 2000 bar from said roasted coffee beans or grounds to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added; and (3) so-called “instant coffee” or “soluble coffee” prepared from roasted coffee beans to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added, but in which a pulverized coffee component is specifically excluded. The formulation including glycerin leads to increased solubility and bioavailability of resveratrol. By adding a formulation containing resveratrol and glycerin to roasted coffee beans and/or instant coffee, consumers enjoy the health benefits of resveratrol in their coffee without drinking red wine.
摘要:
A method for treating roasted coffee beans, to improve an extraction rate of coffee component from the roasted coffee beans and to increase a richness component content of the roasted coffee beans while suppressing acidity generation in the roasted coffee beans, includes: a sugar-enriching treatment step in which roasted coffee beans are brought into contact with sugar to increase a sugar content of the roasted coffee beans; and a water vapor treatment step in which the roasted coffee beans having undergone the sugar-enriching treatment are brought into contact with water vapor.
摘要:
A process for producing acid reduced coffee beans. An aqueous solution including potassium hydroxide and polyethylene glycol is applied to whole bean coffee immediately after roasting. The water from the solution dries, leaving a coating that reduces oxidation and flavor loss from the whole bean coffee, and which reduces the acidity of coffee beverages subsequently brewed from the beans. In an alternate embodiment, the potassium hydroxide and polyethylene glycol are applied in separate steps.
