Outline of Annual Research Achievements

The main achievements of this project are shown in the following two aspects after the study carried out over a six-month period.
1.two different frying oils samples has been prepared under 180, 200, and 220℃ frying temperatures will be used for the future e-nose analysis and toxic side effects investigation. 2.We successfully prepared polar compounds using a chromatographic glass column from the prepared fried oil samples.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

The great effort and kind cooperation provided by the school and laboratory, the project is progressing smoothly as expected.

Strategy for Future Research Activity

According to the project plan, our future work will mainly focus on separating/isolating and purifying the polar compounds and then subject it to human hepatocellular carcinoma HepG2 cells for the determination of the cytotoxicity of different polar compounds such as ox-TG, TGD, TGO etc. in vitro. Meanwhile, we will also work on the investigation of the changes in the odor of oil samples that fried under different temperatures and times using e-nose system.
