Describes a gas chromatographic method for determining the wax content of crude, degummed, neutralized, winterized, and fully refined vegetable oils, such as sunflower, soybean, rapeseed, corn, and rice bran oils.

This Technical Specification specifies a gas chromatographic method for determining the wax content of crude, degummed, neutralized, winterized, and fully refined vegetable oils, such as sunflower, soybean, rapeseed, corn, and rice bran oils. It is not applicable to olive oils or olive pomace oils.

Waxes are esters of long chain fatty acids and fatty alcohols (having C₂₀ or longer saturated carbon chain).

The wax content is expressed in milligrams per kilogram of oil.
