Effect of Hydrogenation on Some Physical Properties of Canola Oil

Abstract
Canola oil from mixed seeds of cultivars Regent, Tower and Candle and oil from cultivar Regent were hydrogenated under selective (200°C and 48 kPa hydrogen pressure) and nonselective conditions (160°C and 303 kPa) using two different commercial catalysts. The physical properties of the hydrogenated oils determined were dropping point (Mettler), solid fat content by wide‐line NMR, solid fat index by dilatometry and melting behavior by differential scanning calorimetry. Hydrogenation conditions had an important effect on physical properties. Differences were also observed between the oils and the catalysts.
