The present invention relates to a A process for providing a fraction enriched in polyphenols from a starting material, the process comprises the steps of: (i) solubilizing the starting material in an aqueous solvent; (ii) adjusting pH to below pH 3 (preferably about pH 1); (iii) contacting the starting material with a chromatographic resin; (iv) desorbing the polyphenols from the chromatographic resin to provide an eluate comprising the polyphenols; (v) adjusting pH of the eluate to above pH 3.5 (preferably pH 4); and (vi) separating the eluate from the eluted polyphenols to obtain the fraction enriched in polyphenols. The invention furthermore related to products comprising such polyphenols enriched fractions.

Provided is a method of producing a purified chlorogenic acid-containing composition, including: a first step of dispersing or dissolving a raw material chlorogenic acid-containing composition in an aqueous solution of organic solvent; a second step of removing a precipitate from a dispersion or a solution obtained in the first step; and a third step of bringing a solution obtained in the second step into contact with activated carbon including activated carbon (A) having a pore volume of from 0.3 mL/g to 1.0 mL/g and activated carbon (B) having a pore volume larger than that of the activated carbon (A), in which a difference [(B)−(A)] in pore volume between the activated carbon (A) and the activated carbon (B) is from 0.1 mL/g to 1.5 mL/g.

A method for the intermediate processing of coffee beans, utilizing natural thermal mineral spring water, where in the beans have reached a parchment stage of production. The coffee beans with the mucilage layer are delivered to a resting facility concurrently to the combining of the thermal spring water therewith. The thermal spring water having an at least minimal predetermined temperature is added to the resting facility in sufficient quantities to maintain the coffee beans with the mucilage layer in a submerged state for a predetermined time, resulting in a removal of the mucilage layer from the coffee beans. The thermal spring water is subsequently drained from the resting facility and the coffee beans, upon conclusion of the predetermined time for resting. After removing the drained coffee beans from the resting facility the coffee beans are delivered to additional processing facilities.

A storage apparatus and method to infuse coffee beans with an aroma emanating from an aromatic substance is provided. The apparatus flavors the coffee beans with the aroma by storing the beans in proximity to the aromatic substance. The apparatus includes a container and a lid detachably coupled thereto to create an inner compartment to store the aromatic substance, a pedestal coupled to the bottom wall of the container, and an internal container disposed on the pedestal and having a plurality of openings, the internal container designed to store the coffee beans above the aromatic substance. The aroma emanating from the aromatic substance passes through the plurality of openings in the internal container and contacts the stored coffee beans, thereby infusing the coffee beans with the aroma.
