Palm oil is an important component of the world's fat market and is produced by pressing the flesh of the palm fruit material from the oil palm tree. Palm oil contains not only fats and oils but also nutritional components such as vitamin E and carotene. In order to further improve the application value of the palm oil, the palm oil is generally refined and fractionated to obtain grease products with different melting points. Palm stearin is the solid fraction that is separated after the palm oil is frozen and crystallized, and is a by-product of palm olein (the ratio of palm stearin to palm olein is about 1: 3-4). Palm stearin is a good natural raw material for shortening, margarine for pastries, Indian margarine and other products. Palm stearin is also the best choice in animal feed and in oiled products, and can also be used in soap as a partial replacement for tallow.
