## Abstract

The present invention relates to a beetle powder containing at least 67% by weight protein and at least 5% by weight chitin, the weight percentages relating to the total weight of the beetle powder. The invention is also directed to a method for preparing the beetle powder and to the uses thereof, in particular in human or animal nutrition.

## Claims

### Claim 1

Beetle powder comprising at least 67% by weight proteins, at least 5% by weight chitin, and a fat content between 5 and 20% by weight, the percentages by weight being given relative to the total weight of beetle powder, wherein the residual moisture content is between 2 and 15%.

### Claim 2 (depends on 1)

Beetle powder according to claim 1, comprising ash in a content less than or equal to 4% by weight relative to the total weight of beetle powder.

### Claim 3 (depends on 1)

Beetle powder according to claim 1, the proteins of which exhibit a digestibility greater than or equal to 85%.

### Claim 4 (depends on 1)

Beetle powder according to claim 1, comprising between 40 and 60% by weight soluble proteins relative to the total weight of proteins, in which at least 50% of the soluble proteins have a molar mass less than or equal to 12,400 g/mol.

### Claim 5 (depends on 1)

Beetle powder according to claim 1, wherein said fat content is 9% to 17% by weight relative to the total weight of beetle powder.

### Claim 6 (depends on 1)

A method for the preparation of a beetle powder according to claim 1, comprising the following steps:
i) killing the beetles,
ii) pressing the beetles in order to obtain a press cake, and
iii) grinding the press cake.

### Claim 7 (depends on 6)

The method according to claim 6, further comprising a step of drying the press cake.

### Claim 8 (depends on 6)

The method according to claim 6, wherein the method further comprises a step of drying the press cake and before the grinding step and wherein the pressing step is preceded by a step of grinding the beetles.

### Claim 9 (depends on 6)

The method according to claim 6, wherein the method further comprises a step of drying the press cake before the grinding step and wherein the pressing step is carried out hot.

### Claim 10 (depends on 6)

The method according to claim 6, wherein the method further comprises a step of drying the press cake before the grinding step and wherein the step of grinding the press cake is carried out to a particle size comprised between 300 μm and 1 mm.

### Claim 11 (depends on 1)

A feed for a human or an animal comprising the beetle powder according to claim 1.

### Claim 12 (depends on 11)

The feed according to claim 11, in which the beetle powder is used to replace protein flour.

### Claim 13 (depends on 11)

The feed according to claim 11, wherein said animal is a dog or a cat.
