Composition of Lemon Oil Distilled From Commercial Mill Waste

Distilled lemon peel oil, a source of flavoring components, was recovered by steam stripping of waste aqueous effluent emulsion from a lemon oil mill. Compositions of distilled and cold‐pressed oils were compared. Distilled oil was richer in the sparingly water‐soluble oxygenated flavor components, linalool, terpinene‐4‐01 and or‐terpineol. Concentration of citral, the major lemon flavoring component, was the same in both oils; but concentrations of neryl acetate and some unidentified higher boiling components were lower in distilled oil. Odor evaluations and analytical results indicated that distilled oil may be a valuable source of lemon flavoring components.
