Comparative Nutritional Value of Corn Oil and Olive Oil for Growing Chickens

Olive oil is among the most popular supplements of the Mediterranean diet due to its high nutritional value. However, at the same time, because of economical purposes, it is also one of the products most subjected to adulteration. As a result, authenticity is an important issue of concern among authorities. Many analytical techniques, able to detect adulteration of olive oil, to identify its geographical and botanical origin and consequently guarantee its quality and authenticity, have been developed. This review paper discusses the use of infrared and Raman spectroscopy as candidate tools to examine the authenticity of olive oils. It also considers the volatile fraction as a marker to distinguish between different varieties and adulterated olive oils, using SPME combined with gas chromatography technique.

Small Content

The effect of dietary corn oil, olive oil, and rapeseed oil on the vitamin A content of liver and kidney during depletion of the vitamin was studied. Dietary oil had no influence on the rate at which liver stores of the vitamin declined in a 2-month period. Kidney stores of vitamin A rose throughout the depletion period but less markedly in the group fed rapeseed oil. The weight gain of vitamin A deficient rats was reduced somewhat earlier when rapeseed oil was fed but the survival time of rats fed corn oil or rapeseed oil was similar. The rats fed olive oil lived somewhat longer due to its small content of β-carotene. It was concluded that rapeseed oil had only a slight influence on vitamin A metabolism.

Fat Diets

Dietary lipid modulation of alpha-adrenoceptor (adrenergic receptor)- and non-adrenoceptor-mediated contractile properties of isolated rat abdominal aortic segments were assessed during the early developmental period. Rats were raised from conception to 90 days of age on semisynthetic diets containing various types and amounts of lipids. Aortic segments from three groups of rats fed high-fat diets (15% wt/wt) consisting of olive oil, corn oil, or lard as the sole lipid sources were compared with those from rats fed a low-fat control diet containing corn oil (5% wt/wt). alpha-Adrenoceptor activities were assessed by measuring the norepinephrine dose response of the tissue rings with and without partial inactivation of alpha-receptors by benextramine. alpha-Adrenoceptor sensitivity to norepinephrine increased, whereas receptor affinity decreased significantly in rats raised on high-fat diets. Qualitative features of dietary lipids influenced non-adrenoceptor-dependent aspects of vascular contractility. Diets rich in polyunsaturated fatty acids (high- and low-fat corn oil) raised the maximum response to norepinephrine and the contractile response to 60 mM potassium compared with more-saturated diets (olive oil and lard). These results demonstrate an effect of chronic feeding of high dietary fat on alpha-adrenoceptor-mediated contractility of abdominal aortic rings from young Sprague-Dawley rats. Qualitative features of dietary lipids also appear to modify receptor-independent parameters of the contractile response of the arterial tissue rings in these animals.
