| An aroma extract prepared from stored fruits was described as sweet, estery and fruity (peach/apricot/plum-like). Quantitatively, the most abundant components were hydrocarbons like tricose-1-ene (21.4%) and pentacose-1-ene (10.3%) and acids like linoleic acid (15.5%) and palmitic acid (12.3%). 57 esters accounted for 9.0%, providing fruiy shades. methyl N-methyl anthranilate (2.4%), methyl anthranilate (0.7%), and ethyl N-methyl anthranilate (0.2%) provide grape-like notes. As the odor of starfruit is described as peach/apricot/plum-like, γ-lactones (peach-like, C10 0.4%, C11 0.05%, C12 1.8%) and δ-lactones (apricot-like, C11 trace, C12 0.07%, C13 1.5%) are sensory important. Very potent odorants are carotenoid degradation products, a number of them were identified: geranyl acetone (0.3%), β-ionone (0.8%), β-damascenone (0.02%), (E)- and (Z)-dehydro-β-ionone (0.1%, trace), β-ionol (0.9%), and 4-hydroxy-β-iononl (0.05%), as well as some interesting megastigma-4,6,8-trienes (rose-raspberry?, E,E 0.3%, E,Z 0.2%, Z,E 0.9%, Z,Z 0.07%) and oxo-derivatives like megastigma-5,8(E)-dien-4-one (0.3%) and megastigma-5,8(Z)-dien-4-one (0.1%). \\ | An aroma extract prepared from stored fruits was described as sweet, estery and fruity (peach/apricot/plum-like).
