RBD palm oil olein, also known as refined, bleached, and deodorized palm oil olein, is a type of palm oil (minyak sawit) that undergoes a refining process to remove impurities, color, and odor. This process involves bleaching and deodorizing the palm oil to produce a clear, neutral-flavored liquid. RBD palm oil olein is commonly used in cooking and food processing due to its high stability and resistance to oxidation, making it suitable for frying and as an ingredient in various food products.
