The observed increasing levels of oxTAG and polymerisation product concentration with increased frying time were in accordance with the findings for sunflower oil, palm olein, and palm
oil (Arroyo et al., 1992; Arroyo, Cuesta, Sánchez-Montero, & Sánchez-Muniz, 1995). Additionally, Kalogianni,Karastogiannidou, and Karapantsios (2009) stated that relative concentrations of polar polymerisation products, respective to the total polar compounds, were less at low frying loads compared to that of higher frying loads. It was observed that adding potatoes to the fryer increased the concentration of polar compounds in palm oil and the higher the frying load, the more polar compounds were generated.
