Temperature‐Assisted Crystallization of Mustard Oil for Erucic Acid Reduction and Its Impact on Phenolic Compounds, Sterols and Oxidative Quality of Oil During Ambient Storage

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Erucic acid (EA) content of mustard oil (MO) was decreased to < 2% level using temperature‐assisted crystallization with no effect on free fatty acids (FFAs), peroxide value (PV), and color of MO and its olein and stearin variant. Olein was rich in phenolic compounds and had higher antioxidant capacity than MO and stearin.
