Neohesperidin dihydrochalcone sweetness

Neohesperidin dihydrochalcone occurs as a white or yellowish-white powder with an intensely sweet taste.

The presence of a free OH-group in position R or R is necessary for a sweet taste. Table 18.25 shows that the dihydrochalcone of naringin corresponds to saccharin in sweetness intensity, whereas the dihydrochalcone of neohesperidin is sweeter than saccharin by a factor of 20. Conversion of naringin to highly sweet neohesperidin dihydrochalcone (VII) is possible by al-... 

Dihydrochalcones prepared semi-synthetically by reduction of flavanones neohesperidin and naringin have an intensely sweet taste. Neohesperidin dihydrochalcone is used as a sweetener (see Section 11.3.2.1.2). 

Influence of Sweeteners on Bitterness. In model system studies, natural fruit juice sugars were observed to raise the limonin threshold (24). An expanded study of natural and artificial sweeteners (26) demonstrated that sucrose, neohesperidin dihydro-chalcone (NHD), hesperetin dihydrochalcone glucoside (HDG) and aspartylphenylalanine methyl ester (AP) all raise the limonin threshold. At low sweetness levels HDG was the most effective followed by AP and NHD. Sucrose was without effect up to the 2% level. At sweetness levels equivalent to 1% sucrose, HDG, AP and NHD raised the limonin threshold in water from 1.0 ppm to 3.2, 2.5 and 1.3 ppm, respectively. Because of its high sweetness intensity, the concentration of NHD (16 ppm) was considerably lower than HDG (80 ppm) and AP (90 ppm). At 3-10% sucrose sweetness equivalency, the effectiveness of NHD increased substantially, sucrose moderately and HDG slightly, while that of AP decreased. Therefore, the sweeteners HDG, AP and NHD can effectively suppress limonin bitterness at low concentrations. 

A sweet taste is exhibited by some dihydrochalcones (see Section 9.4.2.6), which are obtained by the catalytic reduction of fiavanone glycosides neohesperidin and naringin, which contain bound...
