Characterization of Opuntia ficus indica seed oil from Tunisia

Abstract: International audienceThe lipid fraction of Opuntia ficus indica seeds was extracted and analyzed for its chemical and physical properties such as acid value, free fatty acid percentage (% FFA), iodine index, peroxide value, and saponification value as well as refractive index and density. The yield of seed oil was calculated as 11.75%. The acid and free fatty acid values indicated that the oil has a fairly low acidity. The triacylglycerols, fatty acids, sterols, and tocopherols were identified and their conce… Show more

“…According to variance analysis results, effect of location on oil contents, oleic acid, linoleic acid and erusic acid contents of prickly pear seed and oils were significant in p < 0.01 level. El Mannoubi, Barrek, Skanji, Casabianca, and Zarrouk (), Matthaus and Özcan () and Chougui et al () studied on physico‐chemical properties of different O. ficus‐indica seed and oils, and they determined 5.0–14.4% oil (in dry matter) in the seeds. Oil contents of prickly pear fruit seeds provided from different locations in our study were in the range reported by Matthaus and Özcan ().…”

“…The result of the acute oral toxicity test shows that the product is safe at doses up to 5 ml kg À1 . It has been reported that the lipid fraction of O. ficus-indica seed oil contains polyunsaturated fatty acids (linoleic acid) and monounsaturated fatty acids (oleic acid), and the unsaponifiable fraction contains liposoluble vitamins (tocopherols, vitamin K1), sterols, and carotenoids (b-carotene) (Ennouri et al, 2005;Mannoubi et al, 2009;Oguzhan et al, 2006;Ramadan & Morsel, 2003). The omega-3 fatty acids increase the insulin secretion stimulated by D-glucose by contact with Langerhans islet beta cells (Oguzhan et al, 2006).…”

“…According to Karleskind (1992) showing the relative stability to oxidation of these oils. The high iodine value and oxidative stability show that the seed oils uphold the good qualities of edible oil (Mannoubi et al 2009). The single-dose toxicity test should be conducted in such a way that signs of acute-toxicity and death are revealed.…”
