Deodorized purpose: The pure fatty acid triglycerides is colorless, odorless, but natural oils have their own special smell (also known as stink). The smell is oxidation products, further oxidation of peroxide compounds break down into formaldehyde, thus the oil flavor. In addition, in the process of oil making it will produce odor, such as solvent smell, earthy smell, soap smell, and so on. The process of removing smell of grease peculiar (taste compounds) of is called oil "deodorization"
Deodorization of oil from solvent extraction (when the processing parameters cannot reach deodorizing requirements, it is known as the "desolventizing") is very important, before deodorization, it must first be process by hydration, alkali refining and bleaching, and create favorable conditions of deodorization, conducive to removal of the residual solvent and other odor of grease.
There are many methods of deodorization, vacuum steam deodorization method, gas insufflation method, hydrogenation and polymerization method. Currently the most widely used at home and abroad, the best method is vacuum steam deodorization.
Vacuum steam deodorization method is the process that the flavor substance was removed by superheated steam (under vacuum) in the deodorizing tank. The theory of vacuum steam deodorization is that steam through oil containing flavor components for steam-liquid touch are saturated by volatile malodorous components, and selected and removed according to its partial pressure ratio.
Deodorization process parameters
The oil temperature of batch deodorization is 160 ~ 180 ºC, the residual pressure is 800 Pa, time is for 4 to 6 hours, the amount of direct steam injection is 10% to 15% of oil weight. The oil temperature of continuous deodorizing is 240 ~ 260 ºC, time is for 60 to 120 minutes, the residual pressure is lower than 800 Pa, the amount of direct steam injection covers 2% to 4% of oil weight. The adding amount of citric acid should be less than 0.02% of oil weight. The temperature of heat transfer oil should be controlled within a range of 270-290 ºC.
