Deacidification of lampante olive oil

Deacidification of lampante olive oil by anion exchange resin and aluminum oxide was investigated. The experimental results proved that it is feasible to obtain a refined olive oil with free fatty acids less than 0.3% using anion exchange column. Efficiency of anion exchange resin as a deacidification material was 4 times as that of the aluminum oxide. Peroxides of the investigated olive oil were decomposed by heat treatment of the deacidified oil in presence of a stream of N[2]. K[232], K[270] and delta-K of the refined olive oil were 2.37,0.89 and 0.02, respectively. The results revealed that the untreated olive oil and the oil constituents that retained on the resin exhibited an efficient cytotoxicity against breast carcinoma cell line [MCF7] with IC[50] values of 61.1 and 70.5 micro g, respectively, while deacidified oil did not maintain this property

Effect of dietary fiber and pectin on blood lipids of rats fed on hypercholesterolemic diets

Effect of dietary fiber and its mixtures with pectin on blood serum lipids of male adult albino rats fed on hypercholesterolemic diets for 11 weeks either with 4% dietary fiber or with 2% pectin + 2% dietary fiber or with 4% pectin + 2% dietary fiber yielded rats with significantly lower blood serum cholesterol, phospholipids and total lipids levels than rats fed on hypercholesterolemic diet containing 2% dietary fiber only. Phospholipids/cholesterol ratio decreased significantly when rats were fed on all those hypercholesterolemic diets, maximum ratio was obtained in rats fed on the diet with 4% pectin + 2% dietary fiber
