Abstract:
Disclosed herein is a process for production of an instant coffee product in a high yield, comprising the steps of extracting roast and ground coffee beans with water having a temperature of 80°C or less, to produce a first extract and spent coffee grounds, adding water to the spent coffee grounds to produce an aqueous suspension, hydrolysing the aqueous suspension using a hydrolysing enzyme to produce a second extract and spent remains, adding the first extract to the second extract, optionally after concentration and/or drying of the second extract, to obtain a combined extract, and drying the combined extract to obtain an instant coffee product. The high yield is obtained due to the reduction of enzyme inhibiting substances.
Abstract:
Disclosed is a process for production of a concentrated coffee product, comprising the steps of providing a coffee concentrate obtained from roast and ground coffee beans and adding spent coffee grounds having an average particles size of 0.1- 0 µm to the coffee concentrate. The concentrated coffee product findsuseful applications for spent coffee grounds, increasesthe yield of roast and ground coffee beans, makes it possible to design new properties, and/or improves thedigestive effect and/or mouth feel.
Abstract:
Disclosed herein is a process for preparing a coffee extract, comprising the steps of: providing a mixture of roasted coffee beans and water, milling the mixture of roast coffee beans and water in a pressurised chamber, and separating the milled mixture in a liquid coffee extract and spent coffee grounds. The coffee extract maintains many of the flavour components of the roasted beans.
