Abstract
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.
