While this process creates a stable, shelf-stable product with a high smoke point, it also removes many of the micronutrients, antioxidants, and phytochemicals that were present in the crude, unrefined version. Nuts like walnuts and almonds offer a dense fat profile, while fleshy fruits such as olives and avocados store their oils within the fruit pulp rather than the seed.
Understanding the RBD Process for Vegetable Oils
Chemical Structure: Triglycerides and Fatty Acids Chemically, almost all vegetable oils are composed of triglycerides, a molecule formed by one glycerol backbone attached to three fatty acid chains. The most traditional method is mechanical pressing, where seeds are crushed under immense pressure to squeeze out the oil.
Finally, deodorization involves steaming the oil under high heat to vaporize volatile compounds responsible to "off" flavors or smells. Botanical Origins: Seeds, Nuts, and Fruits The journey of an oil begins with its botanical source, which dictates the fundamental composition.
Understanding the RBD Refining Process for Vegetable Oils
Refining, Bleaching, and Deodorizing After the initial extraction, many vegetable oils are subjected to a refining process known as RBD (Refined, Bleached, Deodorized). Refining neutralizes free fatty acids that cause acidity and spoilage.
