RBD is a term that you will hear commonly used when people are talking about oils of many different types. But what does it mean? RBD is an acronym, which stands for Refined, Bleached and Deodorized. This acronym describes how the oil is processed, and whether it is a refined or unrefined product. It is used to describe a myriad of oils from canola to soy to olive to sunflower to grapeseed and more. However, the refining process is probably very different than you may be picturing, so Ill tell you a little bit more about it.
