Abstract: The object of the present invention is to provide a coffee aroma-containing composition which can achieve such aromatic and good flavor as one obtained immediately after extraction in industrially produced coffee extracts and coffee beverages. The coffee aroma-containing composition is obtained by addition of a liquid to ethyl isovalerate-containing roasted coffee beans, wet-grinding of them to prepare slurry, and stripping of aroma components from the slurry.

Abstract: The present invention aims to provide caffeineless coffee that is rich in flavor. Ethyl isovalerate is incorporated in caffeineless coffee. If the caffeineless coffee is in the form of coffee beans, ethyl isovalerate is incorporated in such a way that its proportion is at least 1 ppb relative to the total amount of the coffee beans.

Abstract: The present invention provides roasted coffee beans that can be stored in the air without experiencing damage to the inherent taste and aroma of coffee and with the change in flavor over time and the oxidative deterioration being suppressed to ensure that they retain a satisfactory flavor. Specifically, ethyl isovalerate or fermented, roasted coffee beans that have been subjected to fermentation and roasting are incorporated in roasted coffee beans.

Abstract: An economical process for producing a milk-added coffee beverage with an enhanced flavor in a process for producing a milk-added coffee beverage produced through a step of heat sterilization of coffee and milk as the main raw materials. The process includes adding a strongly basic substance and/or basic amino acid to the coffee component and conducting the heat sterilization after the milk component is admixed to the coffee component. Coagulation at the step of admixing milk component is prevented and precipitation which tends to arise after the heat sterilization is prevented with the use of a much smaller amount of emulsifier and thickening agent.
