OSI-6 Oxidative Stability Instrument

Definition: All oils and fats have a resistance to oxidation which depends on the degree of saturation, natural or added antioxidants, prooxidants or prior abuse. Oxidation is slow until this resistance is overcome, at which point oxidation accelerates and becomes very rapid.

The length of time before this rapid acceleration of oxidation is the measure of the resistance to oxidation and is commonly referred to as the “induction period”, or Oxidative Stability Index.

The Omnion Oxidative Stability Instruments provide an instrumental determination of the oxidative stability of fats oils and other organic materials, eliminating the time, inconvenience, hazards and errors associated with manual titrations. Continuous data monitoring (up to 24 channels simultaneously) ensures no missed endpoints.
