چکیده
|
A comprehensive lipid profiling has been carried out on the seed oils of two non-conventional oils in morocco,neem (melia azadirachta) and milk thistle (silybum marianum (l.)),in order to evaluate their potential uses. the paper reports the proximate evaluation of the two oils. the major fatty acid (fas) of the neem and milk thistle oil was linoleic (69.2 and 48.26%) followed by oleic (18.9 and 27.7%),the phytosterol marker β-sitosterol accounted for 66.7 and 27.6% of total sterols contained in neem and milk thistle oil respectively. the main tocopherol for neem oil is γ- tocopherol (59.2%) contrary to milk thistle oil where a-tocopherol is the main tocopherol with 82.42%. oxidative stability of both oils was measured at 110 °c at the air flow rate of 20 l/h,neem and milk thistle oil was less stable than other moroccan oils with 5.07 and 5.84 hours respectively. this oil,therefore,has a potential for its use in human nutrition or industrial applications.
