Abstract
Edible fats are an important part of a human daily diet. They have a significant effect on the proper functioning of the human body. During frying, the oil is chemically modified and the fats consumed should have the highest oxidation stability. The subject of the study were samples of olive oil bought at local markets in Gdansk. Samples were heated at 20 °C, 60 °C, 100 °C, 140 °C and 180 °C. The aim of the study was to determine the differences in the level of oxidation of selected edible oils which were heated. Studies were performed using spectrophotometric techniques. The dependence between the level of oxidation of the olive oil samples and the value of the overall color parameter was determined. Based on the results obtained, the lower value of the color parameter overall, means that the oil is more degraded. The used procedure is characterized by an uncomplicated and low cost consuming stage of the preparation of the sample for analysis and also enables rapid analysis.
