Palm Fatty Acid Distillate (PFAD) is a byproduct of the refining process for crude palm oil. It is a brownish-yellow liquid that contains a mixture of fatty acids, including palmitic acid, oleic acid, and linoleic acid. PFAD is commonly used in the production of animal feed, as it is a rich source of energy and fatty acids that are beneficial for animal health and growth. It is also used in the production of various industrial products, such as biodiesel, soap, and candles.
