Fortification cream with Grape seed oil and studying its effect on some chemical, physical and sensory properties.

Abstract

The study showed the effect of using grape seed oil as a source of Omega-6 fatty acids in the production of a cream rich in Omega-6 fatty acids with low cholesterol content. Two treatments of the cream were manufactured with( 2.5, 5.5, 10.5%) one of which was grape seed oil fortified with vitamin E as an antioxidant and the other non-vitamin , The results showed a significant decrease in the cream content of cholesterol and in direct proportion to the increase in the percentage of the fortification compared to the control sample. As for the development in the values of peroxide and fat acidity of the cream samples during storage (0, 4, 8, 12) day At a temperature of 5±1 ° C was lower in cream with a 10.5% fortification rate and above in cream control treatment. The qualitative and quantitative examination of the fatty acids found using the GLC showed a significant increase in the cream content of Omega-6 fatty acids linoleic acid. Physical properties such as Melting point, density and viscosity obtained a decrease in their values relative to the cream of the comparative treatment. Omega-6 fatty acids received a higher sensory evaluation than the comparison sample for color, flavor, texture and bitterness. The preference was for the sample fortified with vitamin E.
