Abstract

Oil was extracted from melon seeds with three different methods (Soxhlet, cold-pressed, aqueous enzymatic extraction), aiming to evaluate its physicochemical properties and oxidative stability. The melon seed oil contained high levels of linoleic acid (53.6 %–70.8 %, w/w), squalene (101.1–164.7 mg/100 g), and β-sitosterol (119.5–291.9 mg/100 g). Results showed that the choice of the extraction method did not alter the fatty acid composition, but impacted on the physicochemical properties, the content of bioactive compounds and oxidative stability of the oil. Specifically, melon seed oil obtained by aqueous enzymatic extraction (AEE) exhibited higher tocopherol content and better oxidative stability compared to the oil obtained by other two extraction methods. Overall, AEE is a promising oil extraction method and could be an alternative to conventional oil extraction methods that could be implemented for the production of high-quality melon seed oil.
