A Survey of the Methods Used for Evaluation of Lipids Oxidation Level

• Języki publikacji: PL

Abstrakty

Do oceny stanu utleniania tłuszczów służy szereg metod. Ich przeglądowi poświęcona jest niniejsza praca. Należy zaznaczyć, że nie istnieje, jak dotąd, żadna uniwersalna metoda, pozwalająca na ocenę zmian, zachodzących w tłuszczach podczas całego procesu autooksydacji. Każda ze znanych metod daje informacje tylko odnośnie jego określonego stadium. (fragment tekstu)

EN

A particular attention has been drawn in the article to fast methods which enable the tracing of undesirable changes taking place in the course of the oxidation of lipids. There has been presented the classical method of peroxide value determination by means of spectrophotometry, which allows for the objectivization of the obtained results. Chromatographic methods and the spectrophotometric IR method enable the evaluation of both primary and secondary products of autoxidation. It must be stressed that the use of those methods allows for the determination of the changes in a rancidity degree before they are detected by means of organoleptic methods. (original abstract)
