ABSTRACT
1,5-Anhydro-d-fructose (AF), a metabolite of starch/glycogen degradation, is a good antioxidant. With the prospect of increasing its applications and use as a food ingredient, AF glucosylation catalysed by the dextransucrase from Leuconostoc mesenteroides NRRL B-512F was performed in the presence of sucrose. This led to AF glucosylated derivatives containing alpha-(1-->6) linkages named 1,5-anhydro-d-fructo-glucooligosaccharides (AFGOS). LC-MS analyses showed that AFGOS with a degree of polymerisation (DP) of up to 7 were synthesised. The amount of AFGOS produced and the average DP increased by using a high sucrose/AF molar ratio and high total sugar concentration. AFGOS were proved to present antioxidant properties quite similar to AF.
