Effect $\beta$-Cyclodextrin on the Taste Quality of Neohesperidin Dihydrochalcone

초록

Neohesperidin dihydrochalcone(NHDC) is an intense sweetener with lingering aftertaste, which limits NHDC to use as a sweetener in food products. This study was conducted to examine the changes of teste quality of NHDC when using $\beta$-cyclodextrin($\beta$-CD) as a taste modifier. A series of $\beta$-CD(0.01%, 0.03%, 0.1%, 0.176%) was added to NHDC solution (100ppm) and the taste quality was evaluated by magnitude estimation. It was found that $\beta$-CD produced a significant effect in the reduction of aftertaste of NHDC(p<0.01) and sweetness as well.(p<0.001). Linear regression(log mean magnitude estimate versus $\beta$-CD concentration) analysis showed that the intensity of sweetness(n=-0.31) decreased more rapidly than that of aftertaste(m=-0.17). This result suggests the possibility that $\beta$-CD may form inclusion complex with NHDC, so that the hydrophobic portion is encapsulated in the cavity of $\beta$-CD and the carbohydrate moiety is oriented to the outside of the cavity. Or it may be that $\beta$-CD competes with the NHDC molecule for binding to the taste receptor, resulting in reduced perceived intensity.
