Research progress in extraction and purification of lycopene and techniques of improving its stability

Lycopene has the effect of inhibiting many kinds of cardiovascular and cerebrovascular diseases and its antioxidant ability has become an investigating spot in recent years.There are numerous approaches to extracting lycopene.Starting with the methods of solvent extraction, ultrasonic assisted extraction, supercritical fluid extraction, high intensity pulsed electric field assisted extraction, membrane separation and macroporous resin adsorption method, the passage specifically discussed the extracting and purifying theory, feature and research report in recent years.The intrinsic stability of lycopene isn't high enough, and the review summarized the techniques of microemulsion, microcapsule and nanometer processing on the foundation of normal processing which are relevant to the improvement in its stability. To conclude, starting with the manufacturing line of lycopene products, the paper analyzed the feature of related techniques and discussed the developing prospects of lycopene products to promote their exploitation and utilization.
