The oxidative stability index (OSI) is a way to quantify how long an oil might be able to resist rancidity in hours at a certain temperature. The temperature can vary, and the test will indicate the temperature and number of hours. We can use this information to compare oils to other oils to see which might have a longer shelf life.
