Refining Vegetable Oils: Chemical and Physical Refining - PMC
Indeed, crude oils like soybean, rapeseed, palm, corn, and sunflower oils must be purified or refined before consumption. The objective of such treatments (chemical and physical refining) is to get a better quality, a more acceptable aspect (limpidity), a lighter odor and color, longer stability, and good safety through the elimination of pollutants while minimizing oil loss during processing.
Abstract and Figures. A hexane-extracted crude soybean oil was degummed in a reactor by counter-currently contacting the oil with supercritical CO2 at 55 MPa at 70°C. The phosphorus content of
Soybean Oil Processing
Oil content of soybean is low, poor plasticity, so it is generally softened before flaking. Flaking temperature should depend on the level of moisture content of soybeans. Soybean moisture for 13% to 15%, softening temperature is usually mastered in 70 ~ 80 degrees, softening time 15 ~ 30 minutes.
In the U.S.A. and in Europe, for soybean oil refining, the caustic soybean oil refining process is by far the most used. The physical refining of palm oil, lauric oils and other fats and oils that have a low phosphatide content by dry degumming and bleaching followed by distillation, deodorization, is 20 to 25 years old and common practice today.
Soybean Oil Processing Byproducts and Their Utilization
Refining of soybean oil, to make a neutral, bland-flavored, and light-colored oil, results in several by-products. The by-products consist of various mixtures of phosphatides, unsaponifiables, glycerides, free fatty acids, and soap. Lecithin contains mostly hydratable phosphatides, together with some free fatty acids and neutral oil (glycerides).
This review presents recent technologies involved in vegetable oil refining as well as quality attributes of crude oils obtained by mechanical and solvent extraction. Usually, apart from virgin oils, crude oils cannot be consumed directly or incorporated into various food applications without technological treatments (refining). Indeed, crude oils like soybean, rapeseed, palm, corn, and
