Disclosed is a process for producing a thermoformable and/or embossable particle/polymer composite using a ground particulate biological substrate S of nutrient tissue and a polymer P, characterized in that (i) the substrate S and the polymer P are homogeneously mixed, then (ii) the substrate S/polymer P mixture is converted into a particle layer, and thereafter (iii) the resulting particle layer is densified at a temperature higher than or equal to the glass transition temperature of the polymer P [Tg.sup.P] to form a thermoformable and/or embossable particle/polymer composite,
where (a) the substrate S comprises extracted ground coffee beans; and (b) the polymer P is thermoplastic and has a Tg.sup.P≥20° C. measured according to DIN EN ISO 11357-2 (2013-09).

Furthermore, a process for the manufacturing of a particle/polymer molding, a particle/polymer molding and its use as an element in buildings or in furniture are disclosed.

The present invention relates to a method for producing roast coffee beans with improved aroma, wherein extracted roast coffee beans are treated with an aqueous liquid comprising glycosidase to hydrolyse carbohydrates in the coffee beans, and the aqueous solution is subsequently used to infuse green coffee beans before roasting.
