## Abstract

A process for the manufacture of a frozen food product comprising antifreeze peptides, wherein the process comprises one or more of the following steps; (i) a (pre-) freezing) step which is a nucleation dominated freezing process; (ii) a (post-) compaction step using a screw extruder or a (piston) compactor; The invention aims at providing the food manufacturer with a greater flexibility for using antifreeze peptide material in frozen food products when aiming to obtain a product with improved recrystallization properties in combination with a good texture. In particular it has been found that the texture of frozen food products containing antifreeze peptides can markedly be improved by carefully controlling its production method.

## Claims

### Claim 1

A process for the manufacture of a frozen food product comprising AFPs, wherein the process comprises:
(i) a step of rapidly freezing a food composition comprising AFPs such that the product reaches a temperature of −5° C. or lower within 30 seconds; and
(ii) a compaction step using a screw extruder or a compactor.

### Claim 2 (depends on 1)

The process according to claim 1 wherein in step (i) the product is frozen to a temperature of −5° C. or lower in from 0.01 to 25 seconds.

### Claim 3 (depends on 1)

The process according to claim 1 wherein in step (i) the product is frozen to a temperature of −5° C. or lower in from 1 to 15 seconds.

### Claim 4 (depends on 1)

A process according claim 1 wherein step (i) involves one or more of:
(a) surface freezing, onto a cold surface;
(b) freezing of a supercooled system;
(c) decompression freezing;
(d) freezing at very low temperatures;
(e) rapid particulate freezing.

### Claim 5 (depends on 1)

A process according to claim 1, wherein step (i) involves drum freezing of the product.

### Claim 6 (depends on 1)

A process according to claim 1, wherein in step (ii) a screw extruder is used.

### Claim 7 (depends on 1)

A process according to claim 1, wherein in step (ii) the extrusion temperature of the frozen food product is less than −8° C.

### Claim 8

A free-flowing, particulate food product comprising anti-freeze peptide, which maintains its free-flowing nature during storage, obtainable by rapidly freezing the food product such that the food product reaches a temperature of −5° C. or lower within 30 seconds.

### Claim 9 (depends on 8)

The free-flowing, particulate food product according to claim 8, wherein the food product is rapidly frozen such that the food product reaches a temperature of −5° C. or lower in from 0.01 to 25 seconds.

### Claim 10 (depends on 8)

The free-flowing, particulate food product according to claim 8 wherein the food product is rapidly frozen such that the food product reaches a temperature of −5° C. or lower in from 1 to 15 seconds.

### Claim 11 (depends on 4)

A process according to claim 4, wherein in step (e), the rapid particulate freezing is condensation freezing.
