Studies on Nutritive Value of Synthesized Fatty Acid

Abstract

Mixed fatty acids synthesized by air oxidation of paraffin were obtained from the Soviet Union. The mixed fatty acids were fractionated to C_5-6, C_7-9, C_14-16 and C_17-20 fractions by vacuum distillation, molecular sieve and the other methods, and these fractions were esterified with ethanol by usual method. Then, the nutritive value of the each ester was compared with salad oil fatty acid ethyl ester prepared from commercial salad oil by feedings in Wister strain rats. The rats were fed 10% of each ester or contralled ester mixed with basal diets. As the results, there was no difference between the weight gain of the sample ethyl esters prepared from synthesized fatty acids and the salad oil fatty acid ethyl ester.
