In the present work, the choice of oils mixture was based on a
preliminary study that was aiming a new frying oil formulation for
a Tunisian industry. During this preliminary study, different mixtures
of oils (corn oil, sunflower oil, soybean oil, and palm olein oil)
were prepared and studied (data no shown). The mixture that was
characterized by an interesting fatty acid composition, specifically
unsaturated fatty acid one, was chosen to be used for formulation.
Other parameters were also taken into account, especially those
related to food security, physico-chemical properties, respective
stability and costs of the oils considered. As a result, the mixture
used in this study was formulated with sunflower oil and a soybean
one in equal proportions. Characteristics of both oils before
mixture are described in Table 1. An amount of rosemary extract
(RE) was added to this mixture. A control was prepared with the
same amounts of oils and obviously without any extract.
