Abstract
The oxidation products of unsaturated hydrocarbon alpha-farnesene that accumulate in cuticular lipids of stored apple fruits and are involve d in the development of superficial scald showed UV fluorescence. The fluorescence emission band was localised at about 330 nm; the fluoresc ence excitation spectrum resembles the absorption spectrum of the prod ucts, but was more resolved. The corresponding fluorescence was record ed from the surfaces of intact apple fruits. It appears that the fluor escence analysis of farnesene oxidation products is a useful, specific , and sensitive tool to follow their concentrations both in extracts a nd intact fruits.
