A method for obtaining an anthocyanin pigment color composition from carrot plants, comprising:
- (i) foliar spraying an ethylene-releasing compound on carrot plant leaves
- (ii) subsequently, harvesting the carrot plants;
- and
- (iii) isolating anthocyanin pigments from the harvested carrot plants, thereby obtaining the anthocyanin pigment color composition
- wherein the ethylene-releasing compound used in step (i) is either one or a mixture of two selected from 2-chloroethylphosphonic acid, (2-chloroethyl) methylbis (phenylmethoxy) silane;
- (2-chloroethyl) tris (2-methoxyethoxy) silane, and laminocyclopropane-1-carboxylic acid.
