Description

A measure of the degree of unsaturation of a fat or oil. The iodine number is the number of grams of iodine absorbed by 100 grams of a fat or oil. A drying oil will have a high iodine number, such as 120, thus indicating a high degree of unsaturation. Materials with low iodine numbers, such as a wax or nondrying oil, will not oxidize rapidly.

Synonyms and Related Terms

Jodzahl (Deut.); iodine value
