Soybean oil refinery process

Degumming is the process of removing phospholipids, which are natural compounds that can give soybean oil a cloudy appearance and a bitter taste. Phospholipids are removed by adding water to the crude soybean oil and then heating the mixture. The phospholipids form a precipitate that can be removed by centrifugation. next step in the soybean oil refinery process is neutralization. Neutralization is the process of removing free fatty acids from the soybean oil. Free fatty acids can give soybean oil a rancid taste. Neutralization is accomplished by adding a base, such as sodium hydroxide, to the soybean oil. The free fatty acids react with the base to form soap, which can be removed by centrifugation. The third step in the soybean oil refinery process is bleaching. Bleaching is the process of removing pigments from the soybean oil. Pigments can give soybean oil a yellow or brown color. Bleaching is accomplished by adding a bleaching earth, such as Fuller’s earth, to the soybean oil. The bleaching earth absorbs the pigments, leaving the soybean oil with a clear yellow or white color. final step in the soybean oil refinery process is deodorization. Deodorization is the process of removing volatile compounds from the soybean oil. Volatile compounds can give soybean oil a strong odor. Deodorization is accomplished by heating the soybean oil under a vacuum. The volatile compounds are vaporized and removed from the oil.
