Abstract

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

First claim

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

2 . D-allulose syrup according to claim 1 , wherein it has a mass content of D-allulose dimer, expressed by dry mass, ranging from 0.1% to 1.4%.

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

4 . D-allulose syrup according to claim 3 , wherein it comprises, relative to its dry mass:
from 75% to 99% of D-allulose; from 0% to 25% of D-fructose; from 0% to 10% of glucose; from 0% to 1.5% 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 nanofiltering said D-allulose composition so as to provide a retentate and a permeate; a step of recovering the nanofiltration permeate; a step of concentrating this permeate so as to provide the D-allulose syrup.

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

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 which can be obtained by means of the process according to claim 6 .
