Abstract

Safou pulp and Kaso oils have a good nutritional value and olive oil's properties are well known. Totox value and the content of thiobarbituric reactive species were measured over a period of 2 months, at 50°C, to evaluate oxidation of free and maltodextrin-encapsulated oils. Freeze-dried particles were more efficient against oil oxidation than spray-dried particles. The comparison between Safou and Kaso using olive oil as reference demonstrates the best oxidative stability of this first one at 50°C. These oils stored over 3 years at 20°C showed the high amount of Peroxide value and modifications of the fatty acid fraction and composition.
