Compositions for preparing a coffee beverage comprising hydrolysed chlorogenic acid

Abstract

The invention relates to compositions for preparing a beverage, the compositions comprise a microorganism and/or an enzyme capable of hydrolysing chlorogenic acids of a coffee extract to phenolic acids. When a beverage prepared with the compositions of the invention is consumed chlorogenic acids present in coffee extract is hydrolysed to improve antioxidant and/or anti-inflammatory properties compared to a similar conventional beverage.

The invention is claimed as follows: 
     
         1 . A kit for preparing a beverage, comprising:
 a first part comprising a dried coffee extract; and   a second part comprising a component selected from the group consisting of a microorganism, an enzyme capable of hydrolysing chlorogenic acids to generate phenolic acids, and combinations thereof.   
     
     
         2 . The kit of  claim 1 , wherein the first part comprises pure soluble coffee. 
     
     
         3 . The kit of  claim 1 , wherein the second part comprises a component selected from the group consisting of milk protein, vegetable protein, and combinations thereof. 
     
     
         4 . The kit of  claim 1 , wherein the second part comprises a component selected from the group consisting of a creamer, a sweetener, and combinations thereof. 
     
     
         5 . The kit of  claim 1 , wherein the microorganism capable of hydrolysing chlorogenic acids to generate phenolic acids is a lactic acid bacteria.
