Overview
OSI-19 OilStab is an instrument used for testing the oxidative stability of oils and fats. Through the accelerated oxidation test method, the oxidation stability of animal and vegetable oils, as well as oily foods and cosmetics, can be understood, providing important basis for the research on product shelf life and antioxidants. Main applications: Determination of oxidative stability of animal and vegetable oils and fats; Determination of oxidative stability of oily foods; Determination of oxidative stability of oily cosmetics; Evaluation of antioxidant capacity of antioxidants

Principles of Measurement
When samples such as oils and fats are placed at high temperatures and exposed to air, their stabilization period will be greatly shortened. When the stability of the sample is broken (commonly known as rancidity), a large amount of inorganic acidic substances will be rapidly released. By monitoring the changes in acidic substances, the stability time of the sample under accelerated oxidation conditions can be measured. Using extrapolation algorithms, the stability index (OSI) of the sample at room temperature or other temperatures can be obtained. This method is a universal approach in current standards and many national standards.
