Taste Detection of Maltooligosaccharides with Varying Degrees of Polymerization.

ABSTRACT: Previous studies have shown that humans can taste maltooligosaccharides [MOS; degree of polymerization (DP) of 3-20] but not maltopolysaccharides (MPS; DP of >20) and that their taste detection is independent of the canonical sweet taste receptor. The objectives of this study were to determine the DP ranges of target stimuli that are tasted and further to investigate the impact of DP on taste detectability. To achieve this goal, we prepared three food-grade MOS samples with narrow DP ranges using flash chromatography: low (4-6), medium (7-12), and high (14-21) DP samples. Following sample preparation, we asked subjects to discriminate the MOS stimuli from blanks after the stimuli were swabbed on the tip of tongue. All stimuli were initially presented at 75 mM.
