Abstract

A D-allulose syrup including, besides D-allulose, a D-allulose dimer mass content, expressed in terms of dry mass, greater than 1.5%. Also, a method for producing the syrup and the use thereof for producing food or pharmaceutical products.

Claims

1. D-allulose syrup comprising, in addition to the D-allulose, a mass content of D-allulose dimer, determined by gas chromatography (GC), greater than 1.5%.

2. D-allulose syrup according to claim 1, wherein the D-allulose dimer content ranges from 1.9% to 20%.

3. D-allulose syrup according to claim 1, wherein it has a D-allulose content greater than or equal to 75%.

4. D-allulose syrup according to claim 1, wherein it comprises, relative to its dry mass:

from 75% to 99% of D-allulose;

from 0% to 20% of D-fructose;

from 0% to 10% of glucose;

from 1.5% (limit excluded) to 20% of D-allulose dimer.

5. D-allulose syrup according to claim 1, wherein it has a dry matter content greater than 50%.

6. Process for producing a D-allulose syrup according to claim 1, wherein it comprises:

a step of providing a D-allulose composition comprising D-allulose dimers;

a step of nanofiltration of said D-allulose composition;

a step of recovering the nanofiltration retentate;

a step of concentrating this retentate so as to provide the D-allulose syrup.

7. Process according to claim 6, wherein a step of chromatography of a composition comprising D-allulose and D-fructose is carried out so as to provide the D-allulose composition.

8. Process according to claim 7, wherein the composition comprising D-allulose and D-fructose is obtained by epimerization of a D-fructose solution.

9. D-allulose syrup that can be obtained by means of the process of claim 6.
