Concept
Neohesperidin dihydrochalcone
Summary
Neohesperidin dihydrochalcone, sometimes abbreviated to neohesperidin DC or simply NHDC, is an artificial sweetener derived from citrus.
It is particularly effective in masking the bitter tastes of other compounds found in citrus, including limonin and naringin. Industrially, it is produced by extracting neohesperidin from the bitter orange, and then hydrogenating this to make NHDC.
NHDC was discovered during the 1960s as part of a United States Department of Agriculture research program to find methods for minimizing the taste of bitter flavorants in citrus juices. Neohesperidin is one such bitter compound. When treated with potassium hydroxide or another strong base, and then catalytically hydrogenated, it becomes NHDC.
NHDC in pure form is found as a white substance not unlike powdered sugar. It has an intense sweet taste because it stimulates the sweet receptor TAS1R2+TAS1R3 in humans, although this is species-dependent, as the equivalent receptor in rats does not respond to the molecule.
It is roughly 1500–1800 times sweeter than sugar at threshold concentrations; around 340 times sweeter than sugar. Its potency is naturally affected by such factors as the application in which it is used, and the pH of the product.
Like other highly sweet glycosides, such as glycyrrhizin and those found in stevia, NHDC's sweet taste has a slower onset than sugar's and lingers in the mouth for some time.
Unlike aspartame, NHDC is stable to elevated temperatures and to acidic or basic conditions, and so can be used in applications that require a long shelf life. NHDC itself can stay foodsafe for up to five years when stored in optimal conditions.
The product is well known for having a strong synergistic effect when used in conjunction with other artificial sweeteners such as aspartame, saccharin, acesulfame potassium, and cyclamate, as well as sugar alcohols such as xylitol. NHDC usage boosts the effects of these sweeteners at lower concentrations than would otherwise be required; smaller amounts of other sweeteners are needed.
