- This study was done to modify erythritol to change its physicochemical and sensory properties. Erythritol, a four-carbon sugar alcohol, was transglycosylated by Bacillus stearothermophilus maltogenic amylase with maltotriose as a donor molecule. The presence of various transglycosylation products of erythritol was confirmed by TLC and high performance ion exchange chromatography (HPIC). The major transfer product was purified by gel filtration chromatography on BioGel P-2. Examination by LC-MS, matrix-assisted laser desorption ionisation-time of flight mass spectrometry (MALDI-TOF-MS), and 13C NMR showed that the major transfer product was maltosyl-erythritol. Results of 13C NMR of maltosyl-erythritol suggested that linkage was formed between the C1 carbon of glucose unit in maltose and either one of the two carbon atoms of the terminal hydroxyl groups of erythritol, so that a mixture of 1-O- and 4-O-α-maltosyl- erythritol was produced. The sweetness of maltosyl-erythritol was about 40% that of sucrose, and its negative sensory properties were less than those of erythritol.
