Heated fats. Part 3. Biological effect and effect of heating and tempering oils on fatty acid composition of liver, heart and serum lipids of rats.

The study deals with the biological effect caused by changes in fats during heating. The study includes feeding experiments and extraction of serum, liver, and heart from the animals tested. The biological study reveals that animals fed heated oil showed retardation of growth, poor efficiencies, rough, greasy mottled coats, and shortened life span.
