People can obtain crude palm oil (CPO) and palm meal (PE) from palm pulp through the process of boiling, crushing and squeezing; at the same time, in the process of crushing, palm kernels are separated, and then crushed and The hulls are removed, and the remaining kernels are extracted to obtain crude palm kernel oil (CPKO) and palm kernel meal (PKE). Oil palm fruit contains two different oils, palm oil is obtained from the pulp; palm kernel oil is obtained from the palm kernel, the former of the two oils is more important. All of the above products are effectively used in the fields of food, chemical industry and agriculture. It can be said that palm is a good economic plant.
After the above-mentioned primary stage of extraction, crude palm oil and crude palm kernel oil are sent to the refinery for refining, and after removing free fatty acids, natural pigments, and odors, they become salad-grade oils-refined palm oil (RBD PO) and palm oil Salad oil (RBD PKO). Refined palm oil is nearly colorless and transparent in liquid state, and nearly white in solid state.
In addition, according to the needs of different users, palm oil can be further fractionated and processed to form palm oleic acid (PFAD), palm olein (OLEAN), and palm stearin (STEARINE or S). Oil palm fruit contains more lipolytic enzymes, so the harvested fruit must be processed or sterilized in time. Crude palm oil tends to contain more free fatty acids, and the acid value increases rapidly, so it must be refined or fractionated in time.
Palm oil is rich in carotene (0.05%-0.2%), which is dark orange-red. This pigment cannot be effectively removed by alkali refining, and the oil color will be removed to light yellow by oxidation. Under the action of sunlight and air, palm oil will gradually decolorize. Palm oil is slightly sweet and has a pleasant violet aroma. It is semi-solid at room temperature, and its consistency and melting point largely depend on the content of free fatty acids. In the international market, palm oil with low free fatty acid content is called soft oil, and palm oil with high free fatty acid content is called hard oil.
