The Digestibility of Rape-Seed Oil in the Rat

Abstract
Rape-seed oil has been found to have the lowest coefficient of digestibility of any fat, liquid at ordinary temperature, which has been investigated on rats. Crude rape-seed oil was digested to the extent of only 77% while the refined oil gave an average value of 82%. This apparently cannot be traced to a failure of lipolysis but is believed to be related to the poor absorbability of the erucic acid fraction.
