International ClassesA23L 001/27C12C 005/04 AbstractThis invention relates to the in situ process for converting non-free-form xanthophylls to free xanthophylls in the biological material of the plant. The method, more particularly, relates to a method that would liberate xanthophylls by transesterification of acyl-xanthophylls in plant materials which is used as a natural food colorant.Field of SearchPRESERVING OR MODIFYING COLOR BY USE OF DIVERSE ADDITIVEPlant derived tissue containing other than potato Specific dye or pigment per se or compositions containing same Containing antioxidant or antioxidant per se Organic active chemical containing PROCESS OF EXTRACTING OR PURIFYING OF NATURAL DYE Dye extracted from natural product | |
