Frying quality and oxidative stability of high‐oleic corn oils

Abstract: To determine the frying stability of corn oils that are genetically modified to contain 65% oleic acid, high-oleic corn oil was evaluated in room odor tests and by total polar compound analysis. Flavor characteristics of french-fried potatoes, prepared in the oil, were also evaluated by trained analytical sensory panelists. In comparison to normal corn oil, hydrogenated corn oil and high-oleic (80 and 90%) sunflower oils, high-oleic corn oil had significantly (P < 0.05) lower total polar compound levels after … Show more

“…Tables I and II show an increase of the transoleic acid (elaidic acid) content in both oils due to frying, which results in thermal oxidation (Kiritsakis et al, 1989;Warner y Knowlton, 1997;Cuesta y Sánchez-Muniz, 1998;Pantzaris, 1998). Trans-oleic Vol.…”

“…190 o C w wysokooleinowym oleju kukurydzianym znajdowało się znacząco mniej związków polarnych niż w uwodornionym oleju kukurydzianym. Warner i Knowlton [49] zaobserwowali również, że olej kukurydziany konwencjonalny oraz uwodorniony charakteryzowały się niższą jakością sensoryczną oraz stabilnością oksydacyjną w porównaniu z olejem kukurydzianym wysokooleinowym po 17,5 h smażenia frytek w 190 °C.…”

“…However, minor components exerting antioxidative or prooxidative action also contribute to oil performance. In this regard, different reports have shown that oils clearly differing in their degree of unsaturation exhibited similar behavior at high temperatures (Márquez-Ruiz et al, 1995;Warner and Knowlton, 1997;Norman et al, 2003;Norman et al, 2006).…”
