Effect of unsaturation of free fatty acids and phytosterols on the formation of esterified phytosterols during deodorization of corn oil.

For laboratory-scale deodorization of corn oil, saturated fatty acids and deodorization process with steam as stripping gas could obviously esterify FPs to PEs. FPs were abundantly enriched in distillate during the deodorization process with nitrogen as stripping gas, whereas FPs and PEs were distilled simultaneously during the deodorization process with steam. © 2020 Society of Chemical Industry.
