This 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.
