Special Properties of Fats, Oils, and Shortenings

AACC Method 58-14.01
Consistency -- Penetration Method


To determine an arbitrary measure of firmness of plasticized fats by measuring the distance a given weight of defined shape will penetrate fat in a certain period of time. Firmness of the fat is related to the composition and character of the fat, to temperature of the sample at the time of measurement, and to the previous history of the sample. The method is applicable to plastic fats and solid fat emulsions such as shortenings, margarine, butter, and similar products. This method is equivalent to Official Method Cc 16-60 of the American Oil Chemists' Society (AOCS).
