Identification of volatile compounds in cultivars barker, collinson, fortuna and geada of avocado (Persea americana, Mill.) fruit

Abstract The objective of this paper was to determine the volatile profile of four cultivars - Barker, Collinson, Fortuna and Geada of avocado (Persea americana, Mill.) fruit and to perform a detailed study on the effect of volatiles extraction conditions. The best conditions for extraction for Collinson and Fortuna cultivars were by using a mixture of pentane and ethyl ether (2:1) as solvent for 80 min, while for Barker and Geada cultivars, the solvents were hexane and pentane-ether (2:1), respectively but for a shorter extraction period of 60 min. A total number of 158 compounds were separat...
