Study on the change of B (a) P content in camellia oil during the heating process

The change of B (a) P content in camellia oil during two different heating treatments including microwave irradiation and conventional heating was discussed. The results showed that the heating methods affected the content of B (a) P in camellia oil because of different heating mechanisms. In the process of conventional heating, the amount of B (a) P in camellia oil increased with time, but at a certain temperature, oil smoke produced by camellia oil would take away part of B (a) P. As a result, the content of B (a) P detected in camellia oil presented the trend of dropping first, then rising and dropping with time ( < 120min) . While in microwave heating, the content of B (a) P showed a decline after the first growing trend as the increase of power and time.
