ABSTRACT

The resistance of edible oils to oxidative degradation, leading to rancidification, is an important parameter for assessing the quality of oil. This paper presents a new promising method to diagnose the volatile compounds which are products of oil oxidation reactions. Our experiment was carried out using a combined method of UV irradiation as an oxidation acceleration technique, headspace solid-phase microextraction (HS-SPME) as an extraction technique and capillary gas chromatography (GC) as an assay technique. Method precision and sensitivity expressed as RSD (

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN. The program aims at improving the level of publishing and editing practices, increasing the impact of scientific journals on science development, and extending the international range of scientific journals.
