Fat Content Testing & Oxidative Stability (OSI) Analysis

FTS Laboratories provides fat content testing to verify total fat and fatty acid composition against product specifications, along with oxidative stability testing to predict shelf life and rancidity risk in oils, nuts, snacks, and fat-containing ingredients. Our Oxidative Stability Index (OSI) testing serves as the primary indicator for shelf life, with supporting trend markers such as Free Fatty Acids (FFA), Peroxide Value, and p-Anisidine Value tracked over time to characterize oxidative change. Whether you're confirming fat content against a product spec, establishing a shelf life claim, or investigating early rancidity in a stored product, our lab delivers the data needed to support your labelling, quality, and shelf life documentation.
