Abstract

The present invention is directed to a new process for supplementation of beverages with soluble and bio available iron in the form of ferric pyrophosphate. This process allows iron supplementation of beverages at low cost, without affecting either the original taste or the colour of the beverages. It is also directed to a concentrate ferric pyrophosphate-citrate solution and its use in the preparation of an iron enriched beverage. The invention also relates to a beverage obtainable by this process.

Claims

1. Process for the preparation of an aqueous soluble ferric pyrophosphate concentrate, wherein said process comprising the steps of:

(a) adding 0.1 to 5 weight/volume % ferric pyrophosphate to water,

(b) adding 0.15 to 50 weight/volume % citrate salt to the dispersion from (a),

(c) heating the resulting solution from (b) until complete dissolution of ferric pyrophosphate

2. The process according to claim 1, wherein the concentration of ferric pyrophosphate is comprised between 0.4 and 2 weight/volume %.

3. The process according to claim 1, wherein the concentration of citrate and/or derivative thereof is comprised between 4 and 20 weight/volume %.

4. The process according to claim 1, wherein the weight ratio of ferric pyrophosphate to citrate and/or derivative thereof, is comprised between 0.01 and 1.

5. The process according to claim 1, wherein the weight ratio of ferric pyrophosphate to citrate and/or derivative thereof, is comprised between 0.05 and 0.5.

6. The Process according to claim 1, wherein the citrate salt is selected from mono sodium citrate, and tri sodium citrate.

7. The Process according to claim 1, wherein the heating step of step (c) is performed by heating the solution at a temperature comprised between 80 to 120°

C. for 10 to 120 minutes.

8. An aqueous soluble ferric pyrophosphate concentrate obtainable by the process of claim 1 and comprising 0.25 to 12.5 g Fe/l.

9. Use of an aqueous concentrate according to claim 8 for the production of a beverage supplemented with 1 to 60 mg Fe/litre.

10. The use according to claim 9, wherein the beverage is selected from juice, non carbonated soft drink, milk and fruit juice.
