Extraction from Natural Sources: The extraction of biobased food additives involves sourcing these substances from natural materials such as plants, fruits, vegetables, and marine organisms. For example, colorants like carotenoids (found in carrots) and anthocyanins (found in berries) are extracted directly from these natural sources. Similarly, certain flavorings and preservatives can be isolated and purified and then used as food additives. The extraction process typically involves mechanical or chemical methods, including pressing, distillation, and solvent extraction. The goal is to obtain high-purity additives while preserving the natural properties of the source material.
