Characterization of Potent Aroma Compounds of Cape Gooseberry (Physalis PeruvianaL.) Fruits Grown in Antalya Through the Determination of Odor Activity Values
This article presents the investigation of the aroma profile of cape gooseberry (Physalis peruviana L.) grown in Antalya, Turkey. The analyses were carried out by means of liquid-liquid extraction followed by gas chromatography-flame ionization detection and gas chromatography-mass spectrometry for quantification and identification, respectively. Sensory analysis confirmed that the organic extract obtained by liquid–liquid extraction was representative of cape gooseberry odor. A total of 83 volatile compounds were identified and quantified in fruit pulp, including 23 esters, 21 alcohols, 11 terpenes, 8 ketones, 8 acids, 6 lactones, 4 aldehydes, and 2 miscellaneous. The main aroma components of the cape gooseberry (concentration >3%) were γ-hexalactone (17.66%), benzyl alcohol (17.22%), dimethylvinylcarbinol (6.54%), 1-butanol (5.71%), 2-methyl-1-butanol (5.22%), cuminol (3.98%), γ-octalactone (3.64%), and 1-hexanol (3.25%). The calculated odor activity values suggest that γ-octalactone, γ-hexalactone, eth...
