Abstract

The glycosidically bound volatile fraction of baby kiwi ( Actinidia arguta ) was studied. Glycosidic precursors were isolated from juice by adsorption onto an Amberlite XAD-2 column. After enzymatic hydrolysis with Rapidase AR2000, the released aglycones were analyzed by GC-MS. Alcohols, terpenoids, and benzenoids were the most abundant compound classes. Aromatic compounds and norisoprenoids showed the highest concentrations. Major compounds were 2,5-dimethyl-4-hydroxy-3(2H)-furanone (Furaneol), benzyl alcohol, 3-hydroxy-β-damascone, hexanal, and (Z)-3-hexen-1-ol. Precursors of aroma compounds including benzoic acid, cinnamic acid, and coniferyl alcohol were also found. Eugenol, raspberry ketone, and 4-vinylguaiacol were identified for the first time in the fruit of an Actinidia species. The high concentration of 2,5-dimethyl-4-hydroxy-3(2H)-furanone in bound form (95.36 μg/kg) is particularly interesting and justifies further investigation.
