    How the Rancimat method helps producers of natural oils qualify the value of their product

    Classical fat parameters such as the acid number or peroxide value describe the current status of oils and fats. However, those parameters can only be used to make limited predictions about the stability of the end product. Here, the Rancimat method comes into the picture. This free white paper explains how rancidity arises and how the Rancimat method can be used to measure the oxidation stability of vegetable oils and fats.
