Abstract
The Mettler FP3 automatic dropping point apparatus was used for the determination of melting points of a variety of edible fat products. The instrument was particularly suitable for this purpose because of the availability-of different heating rates. Advantages were the fully automatic heating, the automatic and objective endpoint determination, the application for melted as well as solidified samples (shortening, margarine, butter), and good reproducibility of results. A standard laboratory method for melted fat samples has been suggested.
