Fifty repeated deep frying of leavened doughs with 0-2% salt content was performed for 1-5 min at 160-200?. While K232, K270, p-anisidine and polymer triglycerides contents of fried dough oil (FDO) were noteworthy (p < 0.05) affected by the frying temperature and the frying time, the dough salt content did not affect these values significantly (p > 0.05). The combined effects of frying temperature and time on K270, p-anisidine and polymer triglycerides contents were significant (p < 0.05). The effects of interaction of frying temperature and dough salt content on p-anisidine value were found to be significant (p < 0.05). The optimum frying conditions to minimize the K232, K270, p-anisidine values and polymer triglyceride content of FDO were observed where the frying time was 1 minute, the frying temperature was 160? and the salt content was 2%.eninfo:eu-repo/semantics/closedAccessRepeated FryingPolymer TriglyceridesK232 and K270 ValuesP-Anisidine ValueQuality ParametersLipid OxidationArticle100149572-s2.0-85158112401Q4WOS:000976499700006Q4
