## Abstract

The present invention relates to a method of producing an extract of green coffee wherein green coffee beans are subjected to a heat treatment and extracted without being roasted.

## Claims

### Claim 1

A method of producing a coffee extract, comprising:
a) heat treating green coffee beans at a temperature of between 100° C. and 180° C. for at least 5 minutes and maintaining the moisture level between 6% and 20% of the total weight of the coffee beans; and
b) extracting the treated coffee beans of step a) to produce a liquid coffee extract,
wherein the coffee beans and/or the coffee extract is not subjected to roasting.

### Claim 2 (depends on 1)

The method of claim 1 wherein the green coffee beans are heat treated at a temperature of between 130° C. and 160° C. for 20 minutes to 120 minutes in step a).

### Claim 3 (depends on 1)

The method of claim 1 wherein the heat treatment of step a) is performed by contacting green coffee beans with steam.

### Claim 4 (depends on 1)

The method of claim 1 comprising grinding the coffee beans.

### Claim 5 (depends on 1)

The method of claim 1 wherein the heat treated green coffee beans are extracted with an aqueous liquid in step b).

### Claim 6 (depends on 1)

The method of claim 1 comprising drying the extract obtained in step b).

### Claim 7 (depends on 1)

The method of claim 1 wherein the extract obtained in step b) comprises more than 4 g of chlorogenic acids per gram of green coffee beans being extracted.

### Claim 8 (depends on 1)

The method of claim 1 comprising preparing a food or beverage composition from the extract obtained after step b).

### Claim 9 (depends on 8)

The method of claim 8 wherein the food or beverage composition is a powdered beverage product.

### Claim 10

A capsule for preparing a beverage by injection of a fluid, comprising a closed chamber and a member for allowing the beverage to flow out of the chamber, the closed chamber of the capsule comprising ground green coffee beans that have has been heat treated at a temperature of between 100° C. and 180° C. for at least 5 minutes while maintaining the moisture level between 6% and 20% of the total weight of the coffee beans, the green coffee beans have not been subjected to roasting.

### Claim 11 (depends on 10)

The capsule of claim 10 wherein the volume of the closed chamber is between 10 and 100 ml.

### Claim 12 (depends on 10)

The capsule of claim 10 wherein the moisture level was maintained between 8% and 15% of the total weight of the coffee beans while the coffee beans were heat treated.

### Claim 13 (depends on 1)

The method of claim 1 wherein the green coffee beans are heat treated at a temperature between 130° C. and 160° C. for 30 minutes to 90 minutes in step a).

### Claim 14 (depends on 1)

The method of claim 1 wherein the green coffee beans are heat treated at a temperature between 100° C. and 130° C. for 25 minutes to 180 minutes in step a).

### Claim 15 (depends on 1)

The method of claim 1 wherein the moisture level is maintained between 8% and 15% of the total weight of the coffee beans while the coffee beans are heat treated in step a).

### Claim 16 (depends on 6)

The method of claim 6 wherein the extract is dried at a temperature less than 180° C.
