Rancidity is a process that occurs as a result of the oxidation of unsaturated fats and oils in foods and causes food to spoil when it is above a certain level. The method used to determine rancidity in foods is to be measured amount of malonaldehyde, the final product of Thiobarbutiric acid in the food. The rancidity is inevitable in foods containing fat or oil. In this study, the storage and the UV-C effect on the its sensory quality of the rancidity process consisting in stuffed pasta (mantt) including minced beef and fat, producing traditionally in Turkey was examined. According to the obtained results, it was concluded that the amount of malonaldehyde increased by UV-C radiation did not affect the sensory properties of the samples (p <0.05), while the negative effect of the rancidity levels formed during storage on the sensory quality (p <0.05). More research is needed on this topic.
