| 摘要 |
The invention discloses a process for the extraction of lycopene from tom ato by-products characterised in that said extraction is performed by means of a solvent mixture comprising two or more components, wherein one is apola r or moderately polar and has affinity for lycopene and at least one of the other solvents is polar. As example, a first solvent is an apolar solvent, a second solvent is a protic polar solvent, a third optional solvent is an ap rotic polar solvent. In particular, said mixture has the following compositi on: hexane 10%-80%, ethanol 10%-60% and acetone 10%-60%. The use of multicom ponent mixtures characterised by high extractive activity, fast extraction k inetics is one of the advantages of the present invention. |
