Bleaching uses activated clays or carbon to remove pigments and other suspended solids. 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.
Polyunsaturated Fatty Acids (PUFA): Multiple double bonds, remaining liquid but highly reactive. Botanical Origins: Seeds, Nuts, and Fruits The journey of an oil begins with its botanical source, which dictates the fundamental composition.
