Analysis of the Oxidative Stability of Deep-Frying Oil

Easy, fast and reliable chemical tests to monitor the degradation of frying oil and to determinethe shelf life of fried products and snacks with CDR FoodLab

Poster of the Study of Hamburg UniversityCDR FoodLab®, the analytical system for oils and fats, was used during the study entitled “Analyses of the oxidative stability of deep-frying oils”, performed by Katharina D. Placke, Jan Fritsche (Hochschule für Angewandte Wissenschaften Department Ökotrophologie Hamburg) and Kim K. Kleeberg (Dr. Kim Kleeberg Umweltanalytik Hamburg) on behalf of the University of Hamburg. The results of the study were presented at the 6th edition of the Euro Fed Lipid Congress, held in Athens in 2008 and devoted to the theme of “Oils, Fats and Lipids in the Third Millennium: Challenges, Achievements and Perspectives”.

The aim of the study was to compare the oxidative stability of traditional sunflower oil with that of oil containing high levels of oleic acid (high oleic oil). The research focused on the assessment of several chemical parameters related to the behaviour of both oils during the deep-frying process. These parameters also included the determination of the variations of p-anisidine using CDR FoodLab®. CDR FoodLab® is in fact able to determine the content of p-anisidine in an oil or fat within 2 minutes without the need of using toxic reagents. Furthermore, with CDR FoodLab® you can test cooking oil in order to determine Free Fatty Acids, Peroxide Value.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
