## Abstract

The invention relates to a method for producing a hydrocolloid with an improved water-binding ability in which the hydrocolloid is treated in a mixture with water in a high pressure homogenization process at at least 100 MPa.

## Claims

### Claim 1

A process for increasing or stabilizing water binding capacity of carrageenan, comprising:
applying a pressure difference of at least 200 MPa across at least one nozzle to an initial mixture including carrageenan with water, wherein the initial mixture of the carrageenan with the water contains 2 to 4 wt.-% of carrageenan, wherein the initial mixture of the carrageenan with the water is subjected to at least a dissolution temperature of the carrageenan in the water;
releasing the pressure difference across the at least one nozzle to provide a treated mixture including the carrageenan having an increased or stabilized water binding capacity than in the initial mixture.

### Claim 2 (depends on 1)

The process according to claim 1, comprising cooling the treated mixture to form a gel, wherein the carrageenan in the gel has lower syneresis and/or higher gel strength than in the initial mixture.

### Claim 3 (depends on 1)

The process according to claim 1, wherein the pressure difference is released in at least two stages through at least two nozzles and a pressure difference of at least 1 MPa is released through each of the nozzles.

### Claim 4 (depends on 3)

The process according to claim 3, wherein the pressure difference that is released through each of the nozzles is a pressure of at least 5 MPa.

### Claim 5 (depends on 1)

The process according to claim 1, wherein the initial mixture comprises the carrageenan with at least one of xanthan, starch, agar-agar, alginate, locust bean gum, guar gum, pectin, cellulose, carboxymethyl cellulose, methylcellulose or hydroxymethyl cellulose.

### Claim 6 (depends on 1)

The process according claim 1, wherein the initial mixture comprises suspension or a solution of the carrageenan.

### Claim 7 (depends on 1)

The process according to claim 1, wherein the initial mixture has a temperature of at least 55° C. due to the applying and releasing.

### Claim 8 (depends on 1)

The process according to claim 1, wherein the initial mixture has a temperature of up to 90° C. due to the applying and releasing.

### Claim 9 (depends on 1)

The process according to claim 1, comprising drying the treated mixture of the carrageenan with water subsequent to the releasing by spray drying or fluidized bed drying.

### Claim 10 (depends on 1)

A process for creating a food mass including the treated mixture provided by the process according claim 1, comprising mixing the treated mixture into a food mass subsequent to the releasing.

### Claim 11 (depends on 1)

The process according to claim 1, wherein the initial mixture comprises a 3 wt.-% mixture of the carrageenan in water having a temperature of 30° C.
