Thousands of tons of melon seeds could be recovered through the year from melon production. These seeds are an excellent source of vegetable oil with significant health-promoting properties due to their unsaturated fatty acid profile and high content of specific bioactive compounds. However, little information exists about the influence of melon cultivars and oil-extraction methods on oil characteristics. In this study, oils from nine different melon cultivars were evaluated. Additionally, two oil-extraction methods (screw and hydraulic press) were studied. Results showed that melon seeds may be used as a novel source of healthy oils. Higher-quality oils were obtained with the hydraulic press; however, low yields reduced industrial interest in this method. Oils extracted from the different cultivars showed high variability in the content of linoleic (51\u201369%) and oleic (15\u201334%) acids. Regarding vitamin E, \u03b3-tocopherol was the main isoform found in melon-seed oils (99.81\u2013456.73 mg\/kg), followed by \u03b1- and \u03b4-tocopherols. Significant concentrations of tocotrienols (\u03b1, \u03b2, and \u03b3) were also found. Although all cultivars showed positive attributes, principal-component analysis (PCA) showed that Honey Dew and Blanco de Ribatejo could be specifically considered as a potential source of polyunsaturated oils with high concentrations of vitamin E.<\/jats:p>","DOI":"10.3390\/foods9101341","type":"journal-article","created":{"date-parts":[[2020,9,24]],"date-time":"2020-09-24T02:56:43Z","timestamp":1600916203000},"page":"1341","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["From By-Product to the Food Chain: Melon (Cucumis melo L.)
