Menthol is highly volatile, it does not fulfill this condition, despite slrop pronounced cooling effect.

The syntheses that are suitable for the products of formula I all use menthol as the starting material. The yellow pigment, referred to as POP ie Product Oxidation of Phloridzine is produced by enzymatic oxidation of phlorizin, a naturally occurring phenolic compound in apple and specific of this fruit.

Comparable calorimetric study was carried out at pH 3 for varying concentrations Table V. Unlike the main food soluble yellow dye currently used – tartrazine E – which is the result of chemical synthesis, the dye in question has been derived from phloridzin by an enzymatic method and corresponds to a portion of the natural color of a juice Apple.
