[Title of award-winning research]
Study on the biocombustibility of secondary lipid oxidation products

[Details of award-winning research]
　Lipid oxidation can adversely affect the aroma and flavor of food and, in some cases, cause food poisoning. The causative substances are called secondary oxidation products, which are produced during the oxidative degradation of lipids and consist of aldehydes, ketones, alcohols, and hydrocarbons. However, there was no information on whether these secondary oxidation products can be utilized by the body if ingested. Therefore, in this study, we first synthesized stable isotope-labeled aldehydes, ketones, alcohols, and hydrocarbons. These were then administered to mice, and the biocombustibility of the secondary oxidation products was evaluated using stable isotope-labeled carbon dioxide in exhaled breath as an indicator. Results showed that ketones and alcohols were biocombustible as rapidly as medium-chain fatty acids, while aldehydes and hydrocarbons were slightly less biocombustible. These results demonstrate that the secondary oxidation products produced by the oxidative degradation of lipids can also be utilized as energy by the body.
