✦ Synopsis

The lipophilicity of aroma compounds was measured by reversed-phase high pressure liquid chromatography (RP±HPLC). The lipophilicity index provided by this technique is the capacity factor, log k w , obtained by extrapolating series of log k values measured at various proportions of methanol in the methanol± water mobile phase. This article lists the log k w capacity factors of 96 ¯avouring compounds belonging to various families ( pyrazines, thiazoles, other heterocyclic compounds, alcohols and phenols, ketones, esters, aldehydes and sulphur compounds).
