Harvey Washington Wiley,
Foods and Their Adulteration
“ Coconut oil may be regarded as the one edible oil which approximates in constitution ordinary butter. Coconut oil has been used very extensively as an adulterant for oleomargarine, since by reason of its high volatile acid it brings that substance much nearer to the composition of butter or indicates a larger percentage of butter therein than is actually present. While it is used extensively as human food its principal value is for soap making. ”
