saponification value

CHEMISTRY

The number of milligrams of potassium hydroxide–KOH required to saponify 1g of fat under specified conditions, which is a measure of the average molecular weight (or chain length) of all fatty acids present in a solution. As most of the mass of a fat/tri-ester is in 3 fatty acids, the saponification value serves to compare average length of fatty acid chains. 

Synonyms Köttstorfer number, saponification number
