Kemin Industries has added a new Oxidation Stability Index (OSI) calculator for its Food Technologies – North America website.

The digital slider tool allows formulators to select the desired number of Oxidative Stability Index (OSI) hours, then provides shelf-life calculations for various fats and oils. This enables manufacturers to determine the ideal oil and antioxidant solution combination they need to meet cost targets and shelf-life goals.

“We developed the OSI calculator so that formulators would have an easily accessible tool to help them maximize the desired shelf life of their food products,” said Courtney Schwartz, marketing director for Kemin Food Technologies. “Many manufacturers are seeking to remove traditionally used synthetic ingredients without switching to a high cost/high-stability oil, which can often reduce the stability of their oil.”

For example, GT-FORT™, Kemin’s oil-soluble green tea extract, can give manufacturers a label-friendly, cost-effective solution to help meet their needs.


The GT-FORT product line of plant extracts for fats and oils assists with oxidation control, significantly delaying lipid oxidation, which lengthens the shelf life of food and maintains brand consistency. The ingredient, which is “Generally Recognized as Safe” (GRAS) by the U.S. Food and Drug Administration, can be used as a clean-label alternative to traditional tocopherols and a replacement to conventional synthetic antioxidants, such Tertiary-Butylhydroquinone (TBHQ). Manufacturers who use the GT-FORT solution can benefit from a consumer-friendly option that will not negatively impact sensory attributes, is heat stable and does not precipitate in the oil. GT-FORT combines the benefits of oil solubility with the antioxidant properties of traditional green tea extract, making it an ideal solution for oils, snack food and bakery products, as well as sauces and dressings.

Disclaimer: This tool is based on internal studies conducted by Kemin on all of the oils represented. A regression analysis was completed to estimate proper OSI hours based on our internal studies. Values should be used as an indicator and should be validated in your specific application.
