Rg. Buttery et al., IDENTIFICATION OF 2,5-DIMETHYL-4-HYDROXY-3(2H)-FURANONE (FURANEOL) AND 5-METHYL-4-HYDROXY-3(2H)-FURANONE IN FRESH AND PROCESSED TOMATO, Lebensmittel-Wissenschaft + Technologie, 27(6), 1994, pp. 592-594
The water-soluble volatile components of fresh tomatoes were isolated
by liquid-liquid continuous ether extraction of filtered blended tomat
o and separated from non-volatiles by high flow dynamic headspace samp
ling, after careful evaporation of the ether. Capillary GC-MS analysis
identified the important aroma compound 2,5-dimethyl-4-hydroxy-3(2H)-
furanone (furaneol) and the related compound 5-methyl-4-hydroxy-3(2H)-
furanone occurring in the fresh tomato at concentrations of the order
of 2 mg and 10 mg/kg of tomato respectively. From the odor threshold a
nd concentration evidence it seems probable that Furaneol contributes
to fresh and processed tomato aroma.
