Abstract
The present invention provides a method of reducing acrylamide in an aqueous coffee extract, the method comprising: contacting an acrylamide-containing aqueous coffee extract with spent coffee grounds at a temperature of 70 to 120° C. for at least 30 minutes to form an acrylamide-depleted coffee extract.
Claims15
A method of producing a soluble coffee product, the method comprising:
- (i) performing an aqueous extraction of roast and ground coffee beans at a temperature of at least 175° C. to provide spent coffee grounds;
- (ii) providing further roasted and ground coffee beans;
- (iii) performing an aqueous extraction of the further roasted and ground coffee beans at a temperature of from 175 to 220° C. to obtain an acrylamide-containing aqueous coffee extract;
- (iv) reducing acrylamide in the acrylamide-containing aqueous coffee extract to obtain an acrylamide-depleted coffee extract by contacting the acrylamide-containing aqueous coffee extract with the spent coffee grounds at a temperature of 70 to 120° C. for at least 30 minutes to obtain an acrylamide-depleted coffee extract;
- and
- (v) drying the acrylamide-depleted coffee extract to provide the soluble coffee product.
3 more elements
A method according to 1, wherein the step (i) of performing the aqueous extraction of roast and ground coffee beans is performed at the temperature of at least 200° C.
