The document discusses the attributes required of edible oils used for deep frying applications. It notes that frying is commonly used in food preparation and that oils are important for heat transfer, flavor development, and texture modification. Ideal frying oils should be heat stable and resist oxidation, hydrolysis, and flavor deterioration. Palm olein is identified as a suitable blending oil due to its oxidative stability and abundant supply. The document recommends blending palm olein with more unsaturated oils like soybean and sunflower oils to improve the stability of frying oils.
