Wenlu Zuo, Xuechao Hu, Yaqiong Yang, Ling Jiang, Lujing Ren, and He Huang
An improved method for the determination of saturated aliphatic aldehydes (SAA) in oils, which is used to monitor the changes of SAA content during the oxidation of DHA-rich oil is developed. A Michael addition reaction is found to significantly reduce the AV of oxidized oils, while the concentration of SAAs does not display significant differences and can clearly identify the low-quality oil.
