FA composition (%, fw) of Sicilian strawberry trees with different geographical origin. Data are expressed as mean ± standard deviation of n = 3 samples per location, where every sample was analyzed in triplicate. S1: sample from Castelbuono (Palermo, Italy); S2: sample from Castanea delle Furie (Messina, Italy); S3: sample from Caltagirone (Catania, Italy); S4: sample from Pedara (Catania, Italy). SFA: saturated fatty acids; MUFA: monounsaturated fatty acids; PUFA: polyunsaturated fatty acids; UFA: unsaturated fatty acids.
