Simultaneous determination of free/conjugated phytosterols and phytosterol oxidation products in vegetable oils by liquid-liquid extraction coupled with SPE-GC-MS

Sen Dang, Lijuan Wang, Sicong You, Baocheng Xu et autres

A method for the simultaneous determination of free/conjugated phytosterols and phytosterol oxidation products in vegetable oils was developed and validated in this study. Free phytosterols (FPS) and free phytosterol oxidation products (FPOPs) were directly separated and quantified by SPE-GC-MS, while conjugated phytosterols …

Oxidative Stability of Phytosterols in Camellia Seed Oil During Heating: The Impact of Different Antioxidants

Dongkun Zhao, Xin Wang, Sicong You, Lijuan Wang et autres

Phytosterols (PS) have specific oxidation rules in different lipid media. After oxidation, PS will form oxidation products, which has potential physiological toxicity to the human body. Camellia seed oil (CSO) is a unique emerging edible oil in China. This oil has a …

Thermal Oxidation of Phytosterols in Purified Vegetable Oils With Typical Fatty Acid Compositions

Qingxu Ma, Sicong You, Yu Hui, Jingwen Li et autres

ABSTRACT Vegetable oils are the main source of phytosterols (PS) for human beings. However, vegetable oil usually requires high‐temperature treatment during the cooking process of Chinese food, which in turn causes the PS to be oxidized to form phytosterol oxidation products (POPs) …
