Seed oil processing | Soybean oil processing | Alfa Laval
First in oil with Alfa Laval. Reliable seed oil processing equipment covering all steps of refining for any type of edible seed oil. Oilseed processing solutions for boosting capacity, limiting loss and increasing yield, creating new profitable possibilities. Improved sustainability and reduced operational costs thanks to unique technologies
Side reactions, particularly isomerization of polyunsaturated fatty acids, should be minimized. The quality of physically refined oil is close to that of alkali refined oils, but losses of neutral oil are lower and the environment is less polluted. Among other methods of physical refining the application of selective membranes is promising.
Physical Refining of Vegetable Oils
Physical Refining of Soybean Oil. A prerequisite for physical refining of soybean oil was the development of degumming techniques that would lower P and other trace elements to a level that would allow reasonable dosages of silica and bleaching clay, bringing these components to a level equal to totally neutralized oil.
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
Edible Oil Refining: Current and Future Technologies
In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the degree of automation. Over the years, more energy-efficient processes and technologies, resulting in a higher refined oil yield, have gradually been introduced.
The bleaching is a critical step in the refining process of oils [ 57, 58 ], preceded generally by degumming, neutralization, and drying processes. Bleaching is a complex physical and chemical process employed in the refining of vegetable oils. The objective of bleaching (or decolorizing) is to reduce the levels of colored pigments (carotenoids
Supercritical CO 2 degumming and physical refining of soybean oil
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 the crude oil was reduced from 620 ppm to less than 5 ppm. Degummed feedstocks were fed (without further processing,i.e., bleaching) directly to a batch physical refining step consisting of simultaneous deacidification
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).
- Which refining process is used in rapeseed oil?
- zenith process… In fact, miscella refining is used almost exclusively with cottonseed oil and the zenith process (developed in SWEDEN) in the refining of rapeseed oil. In the U.S.A. and in Europe, for the refining of soybean oil, the caustic refining process is by far the most used. We have not sufficient time to report on physical refining.
- How does a high FFA content affect refining yield?
- Soaps and gums that hold a higher molecular weight than neutral oil are expelled through a centrifuge, resulting in neutral oil. The higher the FFA content, the higher the alkali dosage required and the greater the neutral oil loss. A high FFA content leads to higher refining cost and refining yield loss.
- Why does soybean oil quality vary by origin?
- Soybean oil quality varies by origin. These variations are due to the geographic location where the whole soybeans were grown, storage conditions and handling prior to processing. Variations in the quality of CDSBO can lead to a longer, more costly refining process, while simultaneously lowering refining yields.
- What Phosphatides are present in soybean oil?
- TABLE VII gives the chemical formulas of three major phosphatides present in the crude soybean oil. Non hydratable phosphatides are present as calcium and magnesium salts. Conditions under which the seed is grown and stored and the crude oil recovered from the seed, will influence the oil content of minor constituents.
