The permeate of the mixture obtained from crude canola oil using the 20 kDa membrane, at a pressure of 1.0 bar and 10% acidified water was subjected to evaporation under reduced pressure in a rotary evaporator at 70 °C and 600 mmHg for 30 min and then characterized for specific mass, kinematic viscosity, ester content, acidity, moisture, free glycerol content and
calorific value. These results were compared to those obtained using degummed soybean oil [31] and are listed in Table 5 together with the values specified for the B100 biodiesel in Brazil
