It can become very confusing trying to understand organic natural ingredients and the various terms applied to them. I will break down the extraction and refining process for organic seeds and elaborate on the jargon you may have heard but don’t quite understand in this article. So what does Winterization of Vegetable Oil: RBD vs RBDW mean?
All organic oils are extracted from seeds through mechanical pressure. This means the seeds are mechanically pressed to squeeze out the oil. In some cases, the product is simply filtered to remove the non-oil remnants from the extraction, and then sold. The product of this process is called crude or virgin oil. Often times, formulations or recipes call for the use of this crude or virgin oil, especially when they want to preserve the aroma and flavor of the raw material in the end product. Ingredients that are most popularly utilized in the crude or virgin state are olive oil, coconut oil, avocado oil and toasted sesame seed oil, to name a few.
What do you do when your recipe or formula requires the aroma and flavor to be muted? The crude product will then go through a refining process. RBD is an acronym for refined, bleached and deodorized. This is a process that strips a lot of the natural color and flavor from the oil. It also reduces many of the natural nutrient rich qualities of the crude oil. Organic sunflower and canola oil are most typically used as refined.
