Molecular distillation was shown to be a suitable method for the deacidification of EAE-produced soybean oil, allowing one to almost completely remove FFAs while avoiding color darkening. The effects of distillation parameters (evaporation temperature, scraper speed, and feed flow rate) on the physicochemical properties of soybean oil were evaluated in detail.
