| Abstract: | With absorption resin method technical conditions were investigated for refining of gardenia yellow pigment.The optimal parameters were determined as follows:X 5 resin as absorbent,abosrption flow 1.5 mL/min,elution flow 2.5 mL/min.Alcohol/water solution as sample with an absorbency of 45.8 and gradient elution as elution program.The resulted color value was 218.6,refinement yield 88.8 % and the resin life was extended to over 10 times.Meanwhile,the refined pigment did not green in the applied flour food. |
