What role can Oil refining machine play?
Triglycerides are mainly found in vegetable oils, but triglycerides in their pure form are colorless in liquid form and white in solid form. However, a variety of common plant oils are not the same color, these different colors, mainly because the oil contains a variety of pigments. But refining machine decolorization function can remove these pigments, so, refining machine decolorization process in the end to remove what substances?
What substances are removed by the bleaching process of refiner
1. Organic degradation
Organic degradation is the degradation of proteins, phospholipids, sugars and other components of oil seeds with poor quality, and the pigment formed by these degradation is difficult to be removed by adsorbent.
2. Organic pigments
The main organic pigments are chlorophyll and carotenoid. A few oils also contain special pigments, such as gossypol in cottonseed oil, which gives them a dark brown color.
Most of these oil-soluble pigments enter the oil in the process of oil production, and some are generated in the process of oil production, such as the transformation of chlorophyll into the red variant of chlorophyll under the action of high temperature, the interaction of free fatty acids with iron ions to produce dark iron soap and so on.

3. Chromogens
Chromogens are normally colorless, but can be brightly colored by oxidation or by certain reagents. Although these pigments are non-toxic, they have a great effect on the appearance of the oil.
