Oxitest

Fats and oils oxidation stability tests for R&D and QC Labs

The VELP OXITEST subjects the sample to a high oxidative stress environment in order to assess, in a short period of time, the resistance to fat oxidation:

• Established over-pressure of pure oxygen (6 bar, degree 5.0)
• High constant temperature: 90 °C

With the OXITEST Method, the stability test is performed directly on the sample as it is solid, liquid or doughy. The main advantage of the method is that the OXITEST reactor ensures representative results without massive sample preparation.

The results of the OXITEST are expressed through the Induction Period (IP). The IP is the time required to reach the launching point of oxidation, relating to either a level of detectable rancidity or a sudden change in the rate of oxidation. The longer the IP, the higher the stability against oxidation over time.

The oxidation chambers, sample holders and covers are all made of titanium guaranteeing high resistance, excellent chemical compatibility and easy cleaning as well as cost savings as no disposable consumables are required.

Applications

• Quality control of raw materials and ingredients
• Transportation and effects on goods
• Storage period studies
• Product Development and behaviour
• Formula Optimization
• Ingredient and alternative ingredients testing
• Process optimization
• Packaging study and alternative packaging comparison
