Vegetable Oil Analysis System
The study published in the Journal of AOAC International and carried out by Asteriadis S.A. and Minerva S.A. enterprises in partnership with the University of Athens, validated the OxiTester photometric method after comparing it with the official testing method for the determination of oil stability index, commonly known as Rancimat.
Oil Stability index (OSI) is the key parameter that determines the relative resistance of oil to oxidation, thus allowing to evaluate and predict the product shelf life.
The OxiTester method for the determination of polyphenol/stability index in olive oil is simple and fast, and proves to be a valid alternative to the Rancimat method. In fact, the researchers determined a good correlation between the two methods for a wide range of oil samples with remarkably different characteristics. Furthermore, the study highlighted that the OxiTester method requires definitely shorter testing times compared to the Rancimat method.
OxiTester testing time: approximately 6 minutes
Average Rancimat olive oil testing time: 10 - 12 hours.
The OxiTester system
- Enables to determine oil acidity level, amount of peroxides and polyphenols/
- Does not require specialized personnel
- Maintenance cost-free
- Testing method is simple, thus minimizing waste
- Reagents come in disposable pre-filled cuvettes
- Does not require calibration
- High sensitivity and excellent resolution, along with accurate and repeatable measurements
- Compliant with reference standards
- Represents a valid alternative to the Rancimat method for the determination of oil oxidative stability: it measures oil stability index in 6 minutes, against 10-12 hours required by the Rancimat method
OxiTester was conceived, devised and produced by CDR s.r.l., an engineering company based in Florence (ITALY) active in several fields, such as telematics (automatic toll collection systems for motorways and parking places), medical diagnostics (hematology and hemostasis systems), and food diagnostics (systems for the prompt analysis of food).
