Tohoku University Technology: Insoluble antioxidant material for edible oil, etc.: T21-035
Realization of synergistic oxidation inhibition by combination with vitamin E
When unsaturated fatty acid contained in abundance in rice oil and linseed oil, which are expected to have preventive effect against lifestyle-related diseases, is oxidized, it exhibits unpleasant odor and toxicity derived from peroxide and aldehyde. On the other hand, it has been reported that spermine, a polyamine compound, synergistically inhibits oxidation with vitamin E which is widely used as an antioxidant. However, polyamine compound has a characteristic odor and it is relatively expensive, so it is difficult to apply for a general usage. The inventors have found that polyethylenimine (PEI) can be used as an antioxidant with advantage over polyamine compound in term of odor, cost, and oxidation suppression ability. [Effect] - Increase oxidation inhibition by vitamin E - Synergistic antioxidant effect can be obtained for omega-3 oil, which does not well inhibit oxidation by vitamin E - Since PEI is insoluble in oil and highly viscous, it can be used for direct coating on oil storage container to obtain its oxidation supression effect.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): 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, and Showa Medical University.
