Crystalline fractionation of hydrogenated sunflowerseed oil. II. Differential scanning calorimetry (DSC)

This study explored the thermal behavior of hydrogenated sunflowerseed oil sample used in margarine manufacture, which had been previously fractionated by crystallization at different temperatures. Calorimetric diagrams showed that areas per gram were larger when solid samples, rather than liquids,...
