Carotenoid Pigments Encapsulation: Fundamentals, Techniques andRecent Trends

摘要

Supercritical fluids have become an attractive alternative due to environmentally friendly solvents. The methodsthat use supercritical fluids can be conveniently used for various applications such as extraction, reactions, particleformation and encapsulation. For encapsulation purposes, the processing conditions given by supercritical technologyhave important advantages over other methods that include harsh treatments with regard to pH, temperature, light, the useof organic solvents, etc. Unstable functional pigments such as carotenoids extracted from natural sources have been encapsulatedto overcome instability problem. Thus, the most used techniques applicable to this intention are described anddiscussed in this review as well the recent advances and recent trends in this topic that involves the use of supercriticalfluids.
