As a result of its specific molecular structure consisting of a polyene chain with 11 conjugated double bonds and a β-ring at each end of the chain, β-carotene has provitamin A and antioxidant activity (Rodriguez-Amaya, 2001). β-Carotene is present in various plant-based food products. In the human diet, carrots (Daucus carota) are a common source of β-carotene and they are often consumed as processed products (e.g., soups, juices, purees, etc.). One major purpose of food processing is food preservation. The shelf-life of food products may be enhanced by destruction of pathogenic microorganisms and inactivation of spoilage microorganisms and enzymes (Ramaswamy and Marcotte, 2006). Processing might also affect β-carotene in different ways. In this chapter, the effect of processing of carrot-based products on β-carotene stability on the one hand, and on β-carotene bioaccessibility on the other hand, is discussed.
