Biosynthesis of 4-hydroxy-2,5-dimethyl-3(2H)-furanone and derivatives in in vitro grown strawberries.

The biosynthesis of 2,5-dimethyl-4-hydroxy-3(2H) furanone (Furaneol) and its methyl ether and glucoside derivatives has been studied in strawberries. An in vitro system was used for growing this fruit, showing that the presence in the incubation medium of sucrose or hydroxyquinoline hemisulfate has no effect on the bioformation of these compounds. Strawberries in vitro grown showed an increase in furanone content with time, especially between the second and fourth days, to the same extent as field-grown fruits but at a higher rate. Among the precursors added to the incubation medium, D-fructose gave rise to an increase in furaneol and its glucoside derivative of 42.6% and 26.3%, respectively. D-fructose 6-phosphate seems to be the precursor of furaneol in strawberries since, when present in the incubation medium, it produced an average increase of 125% in all furanones contents with respect to control fruits.
