| ABSTRAC Deep-fat frying is the oldest and most popularly known food preparation method. The fried foods have a desirable flavor, color, and crispy texture, making them deep-fat fried foods and are very popular among consumers. Oleic acid is the most abundant monounsaturated fatty acid in all the common edible oils.The effect of potato frying on the quality characteristics of moringa seed oil and olive oil was investigated. The moringa oil and olive oil were used in frying potatoes at 175 0C and the change in the quality characteristics after four times showed a significant difference (P≤ 0.05) between the moringa and olive oil in peroxide value and yellow color but no significant difference (P≤ 0.05) in free fatty acids, iodine value, viscosity, refractive index, and red color between the two samples. Fatty acids compositions of samples after frying were detected using GLC which were palmitoleic (0.1543), palmitic (1.8698), linoleic (0.0616), oleic (70.8325), linolenic (0.1200), stearic (5.0682), arachidic (0.3054), gadoleic (1.4825), behenic (2.1098), and arachidonic (0.1078). Moringa oleifera oil is a high-oleic vegetable oil typical of the Mediterranean region, recognized for its nutritional, technological, and sensorial properties. Its use for frying, alone or in blends, includes the physical and chemical alterations of the oil bath under deep-frying conditions, and the sensory characteristics of fried potatoes | ||||
