Refined rice bran oil is normally refined by physical method to keep the Oryzanol in the refined oil. In chemical process Oryzanol get destroyed by alkali.
For the physical refining of Rice bran oil following processing steps takes place.
Degumming at the best rice bran oil machinery manufacturer in India eliminates phospholipids so as to enhance its physical stability. The process is necessary also to facilitate further steps in refining.
Phospholipids can treat dark coloured oil and they can also serve as precursors of oil off -flavor. Free fatty acids, pigments, and other impurities are also partially removed by degumming.
The impurities have to be removed in the early refining stage for two main reasons
Types of Degumming Suitable for Rice Bran Oil
“Bleaching” is a process of selective removal of pigments and impurities by the physical and chemical interaction of an adsorbent with an oil or fat to improve its quality at the rice bran oil extraction plant.
This process refers to the art of removing
Mectech's Bleaching Advantage
Dewaxing of oil is a process of eliminating higher melting point constituents like waxes or triglycerides from oil by gradually cooling vegetable oils and separating saturated glycerides from the oil. This process is an important part of the extraction process at rice bran oil factory in India.
Normally Dewaxing process carried out at higher temperature (18-20 °C) to avoid the crystallization of saturated triglycerides & amalgamation of waxes & saturated triglycerides.
Mectech’s Dewaxing Advantage
Waxes & Saturated triglycerides which are fairly visible at low temperature are removed in this process to keep the appearance oil clean transform Degummed, Bleached & Dewaxed oil is cooled and filtered to achieve the quality.
Post Bleaching process is required for the oil colour and phospholipids which were not removed completely in earlier processes.
Deodorization achieves vacuum stripping by passing a specific amount of a stripping agent (usually steam) for a specific time through hot oil at low pressure. This is mainly a physical process that removes various volatile components.
Deodorization is a multi-step process comprising
