Guest guest Posted July 20, 2004 Report Share Posted July 20, 2004 Duncan, We were talking about Refined Bleached Deodorized oil which comes from copra. It has a yellow color to it. So they use hexane or other chemicals to remove taste, odor and color. I believe there is still some color left even after rbd. " Traditionally " made oil from freshly grated coconut is colorless, clear as water not cloudy at all and definitely no color. It can be further processed using filters and heat to remove taste and odor and of course moisture. oil color? > In the refined coconut oil, they use chemicals to get rid of the odor, > taste and yellow color.

Guest guest Posted July 20, 2004 Report Share Posted July 20, 2004 Pure coconut is not yellow! If you open a coconut and it is yellow why is that? The reason is because it is full of mold. Coconut oil made from moldy coconuts retains a slightly yellow color. Most RBD oils are colorless because the contaminants have been refined out. Some oils labeled " virgin " coconut oil are yellow because they were made from old moldy coconuts (but not necessarily copra). Yellow coconut oil is not necessarily bad just lower quality.

Is it oxidation of the copra that causes a yellowish or brownish color? There is a good technical article about the refining of oils here: http://www.gtz.de/uvp/publika/English/vol238.htm " Either a chemical or physical method can be used for oil neutralisation (removal of free fatty acids). The chemical process involves the neutralisation of acid using caustic soda, whilst the physical process neutralises by steam distillation. Physical neutralisation is the norm for palm, coconut and palm nut oil. " also I found this: http://www.tis-gdv.de/tis_e/ware/oele/kokosoel/kokosoel.htm " Fats and fatty oils are insoluble in water. However, contact with water may give rise to soluble lower fatty acids and glycerol, which cause rancidity together with changes in color (yellow to brown), odor and taste as well as gelling and thickening.
