Fatty acid composition and rheological behaviour of prickly pear seed oils

Effect of Oil Type and Fatty Acid Composition on Dynamic and Steady Shear Rheology of Vegetable Oils

“…Fatty acids may be located at different triglyceride positions in different oils. Ennouri et al 17 observed low level of viscosity values in prickly pear seed oil at 60 . They reported that this temperature was in the same range as the melting point of palmitic acid.…”

“…Invisible aggregated palmitic acid particles occur because of this temperature difference. Smaller size particles of palmitic acid result in strength of resistance to fl ow and the increase of the viscosity 17 . For this reason cottonseed oil has higher viscosity values than soybean and sunflower oils.…”

“…On the other hand, commercial oils were refi ned, so contain traces of free fatty acid. Ennouri et al 17 have used crude pear seed oil in their study. There is a difference between the oil types.…”

Evaluation of antidiabetic properties of cactus pear seed oil in rats

“…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).…”

“…Cactus pear seed oil (CPSO) is an organic extract that contains fatty acids, represented by linoleic acid, a major polyunsaturated fatty acid, oleic acid, the dominant monounsaturated fatty acid, and palmitic acid, the major saturated fatty acid (Ennouri et al, 2005;Ramadan & Morsel, 2003;Sawaya & Khan, 1982). CPSO supplementation of the diet of normal rats decreased blood glucose, increased liver and muscle glycogen, and decreased low-density lipoprotein cholesterol (Ennouri et al, 2006a(Ennouri et al, , 2007.…”
