In this study the Fourier transform-near infrared (FT-NIR) spectroscopy technique was used to predict the fatty acid and sterol content of sesame. For this purpose, partial least square regression (PLS-R)-based prediction models were developed, which relate the FT-NIR spectra to reference GC measurements. In total, 39 sesame samples were collected from local producers around Muğla Province. Sesame oil was extracted from the seeds by using a screw press and extracted oil samples were analyzed without any refining. The results showed that among different fatty acids found in sesame oil, oleic and linoleic acid contents (which account for 85% of the …

Cocklebur (Xanthium strumarium L.) seed oil is available for biodiesel production as a wild plant species. In the present study, the cocklebur seeds collected from Muslubelen, Yozgat, Turkey, at 1440 m in 2014 were sown in the Bozok University Agriculture Faculty Topçu Research Area during 2015 and 2016. The maximum crude oil ratio was obtained as 35%. Oleic and linoleic acid contents of cocklebur seed oil were determined as 11.37% and 76.97%, respectively. Some important fuel properties such as density, flash point, water content, copper strip corrosion, iodine value, linolenic acid, methyl ester, and sulfated ash content values were measured …
