Tohoku University Technology: Identification method of the cause for fat and oil oxidation: T21-195
Quick and easy elucidation by NIR of the cause for fat and oil oxidation
Fat and oil are easily oxidized by heat and light irradiation during the manufacturing process and storage. Since antioxidant measure depends on the oxidation cause, it is important to determine not only the oxidation level but also its cause in order to maintain the vegetable oil quality. Although a method for identifying the oxidation cause through isomer analysis of lipid hydroperoxide by LC-MS/MS has been reported [1], this method is not versatile since it requires complicated operation, and laboratory level facility and equipment. On the other hand, this research has established a method to identify the oxidation cause using near-infrared spectroscopy (NIR), which is widely used for nondestructive analysis of food product. So far, NIR has been used to evaluate oil oxidation, such as peroxide value, carbonyl value, and conjugated diene value of vegetable oil, but it has not been applied to determine the oxidation cause. This invention is able to quickly and easily identify the cause for fat and oil oxidation.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University - Asahikawa Medical University
