The Bakers’ ABC: U is for Unsaturated compound

Compounds the affinities of the consituents of which are not completely satisfied. The process of hardening oils to make them into fats depends on the fact that the oleic acid of the oil is an unsaturated compound, but, in the presence of pure hydrogen and a catalyst – generally a nickel plate – the oleic acid is changed by the absorption of hydrogen into stearic acid, which is a saturated compound.
