Effect of fructose and glucose supplementation on invertase mediated synthesis of oligosaccharides from sucrose

Summary The total amount of novel oligosaccharides synthesized by -D-fructofuranosidase at pH 7.5 increased three-fold using a medium composed of 1.2M sucrose, 0.5M fructose and 0.1M glucose, as compared to that with only 1.8M sucrose solution. Using 0.6M of the three sugars did not increase yield but reduced rate of sucrose hydrolysis by 72.7%. Synthesis of fructosyl/glucosyl oligosaccharides based on -fructofuranosidase mediated transglycosylation is enhanced by supplementation of sucrose solution with appropriate concentrations fructose and glucose.
