Abstract
Recently, membrane processing has been extensively investigated for purification of vegetable oils due to simple technology and many other advantages. This research has been conducted on adding chemical agents (CaCl2, EDTA and SDS aqueous solutions) to canola oil miscella before ultrafiltration through polyvinylidenfluoride (PVDF) membranes with 100kDa and 50kDa in a magnetically stirred flat membrane cell. SDS solution lowered phospholipids content almost completely. The reduction of phenolic compounds in SDS- and EDTA-pretreated filtered oil was more noticeable than in the processed miscella. In the contrary, the reduction of FFAs was more in the miscella filtered without any chemical agents. The membrane exhibited no appreciable affinity towards tocopherols and carbonyl compounds in the oil samples. SDS and EDTA played important role in oil oxidation, led to increasing the peroxide value.
