Crystallization Behavior of High-Oleic High-Stearic Sunflower Oil Stearins under Dynamic and Static Conditions

Soft (SS) and hard (HS) stearins obtained from high-oleic high-stearic sunflower oil were isothermally crystallized under dynamic (with agitation) and static conditions at 16, 17, 18, 19, and 20 C and 24, 25, 26, 27, and 28 C, respectively. Both fractions crystallized under the α-form at early stage...
