## Abstract

A process for preparing a food or feed composition from J. curcas is disclosed. The method involves adding an acidified aqueous solution to J. curcas components, to a final pH of between 1 and 5, incubating the acidified mixture for a period for a period of at least 1 hour, and centrifuging the incubated mixture to separate the mixture into three physically distinct fractions: (i) a light, upper fraction containing oil, (ii) an aqueous fraction containing soluble acid-extracted components and breakdown products, and (iii) a substantially detoxified solid cake which forms or is used in forming the food or feed composition. The acidified aqueous solution added may be acidified olive vegetation water having a ratio of hydroxytyrosol to oleuropein of between 5:1 to 100:1. Also disclosed are a food or feed composition, and oil and aqueous fractions formed by the method.

## Claims

### Claim 1

A process for preparing a food or feed composition from Jatropha curcas comprising:
(a) crushing or grinding at least 200 kg of one or more Jatropha curcas components to form a slurry, wherein the one or more Jatropha curcas components is a Jatropha curcas plant part selected from the group consisting of leaves, hulls, fruit, or seeds or pre-formed cake thereof;
(b) acidifying the slurry of step (a) to a pH of 1-5 by adding an acidified aqueous antioxidant solution to form an acidified slurry;
(c) incubating the acidified slurry for a period of at least 1 hour;
(d) separating the incubated acidified slurry by centrifuging or decanting into three distinct fractions: (i) a fraction containing oil, (ii) an aqueous fraction comprising unoxidized phorbol esters and curcin, and (iii) a detoxified solid cake; and
(e) further processing the detoxified cake to provide the a food or feed composition.

### Claim 2 (depends on 1)

The process of claim 1, wherein the acidified aqueous antioxidant solution is olive vegetation water.

### Claim 3 (depends on 2)

The process of claim 2, wherein the olive vegetation water has a ratio of hydroxytyrosol to oleuropein of between 5:1 to 100:1.

### Claim 4 (depends on 2)

The process of claim 2, wherein the olive vegetation water further comprises 5-10% (v/v) of an organic solvent.

### Claim 5 (depends on 1)

The process of claim 1, wherein the fraction containing oil is removed from the detoxified solid cake and aqueous fraction, and the detoxified cake and aqueous fraction is further separated to provide three physically distinct fractions.

### Claim 6 (depends on 1)

The process of claim 1, wherein the fraction containing oil, the detoxified solid cake and the aqueous fraction are simultaneously separated from each other.

### Claim 7 (depends on 1)

The process of claim 1, wherein the acidified slurry is acidified to a pH of 2-4.
