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 na + some more technical info. Chemically it is a hydrogenated dihydrochalcone glycoside produced by selective catalytic hydrogenation of neohesperidin, giving a multi-ring flavonoid derivative with high sweetness potency relative to sucrose at low concentrations. NHDC is used as a sweetness enhancer and taste modifier because of its clean sweet note, synergistic effects with high-intensity sweeteners, and ability to suppress bitterness and metallic off-notes. It is stable in neutral formulations and at moderate thermal processing conditions but shows sensitivity to strong acid or prolonged alkaline exposure. Typical quality control is performed by HPLC and LC-MS to confirm identity and assay, and physical properties monitored include particle size, moisture content, and crystalline form because these affect dissolution and sensory performance.

Typical commercial NHDC is presented as an HPLC assay of roughly 95 to 98 percent neohesperidin dihydrochalcone on a dry basis, with the balance made up of identified and minor related compounds plus trace process residues. Common related substances and their typical amounts are unreacted neohesperidin often below 1 to 3 percent, hydrogenation byproducts and chalcone isomers generally totaling 0.1 to 2 percent, and low levels of other citrus flavonoids or sugar-derived impurities making up small fractions. Total unspecified impurities are typically controlled to remain below about 5 percent. Manufacturing controls also limit residual solvents to within regulatory limits, moisture by loss on drying to low single-digit percent, inorganic ash at low levels, and heavy metals to below applicable statutory limits. Analytical methods used for release testing include HPLC-UV for assay and related compounds, LC-MS for structural confirmation, GC for residual solvents, and ICP-based methods for elemental contaminants.
Neohesperidin dihydrochalcone is used as a high-potency sweetener and taste modifier in food and beverage formulations, confectionery, chewing gum, oral care products, and certain pharmaceutical or nutraceutical preparations where bitterness masking or sweetness enhancement is required. It is commonly combined with other sweeteners to improve overall taste profile and reduce aftertaste.
NHDC is sparingly soluble in water at neutral pH; aqueous solubility depends on crystal form and temperature and is typically low, commonly in the low grams per liter or sub-gram per liter range at ambient temperature. Solubility increases markedly in alkaline media where ionization occurs and in common organic solvents such as ethanol, propylene glycol, and certain glycol ethers. The water-soluble sodium salt forms of NHDC are used when higher aqueous solubility is required.
