Neohesperidin dihydrochalcone (NeoDHC) is a phenolic compound prepared from the bitter citrus flavanones naringin and neohesperidin (Horowitz Gentili, 1985). NeoDHC is a white solid with solubility in water of 0.5 g/1, which increases with temperature, but as use level is low, sufficient for most applications.

In the present chapter, various tools such as thin-layer chromatography, high performance liquid chromatography, mass spectroscopy, and NMR used in analysis of flavonoids are discussed. In addition, the relevance and application of such tools in the analysis of flavanones, with emphasis on citrus flavanones, is discussed.

Subcritical water has been used to flavonoids extraction, such as citrus flavanones with selectivity capacity modelled by temperature solubility dependence of the phenolics [24, 21]. The subcritical water extraction (SWE) is based on solubility enhacement of phenolics compounds in high temperature water (100-374°C). To keep the liquid state of water, a high...
