(2) Add purified water to 4 ml scale, add 4 drops of reagent A dropwise, and heat it at 90 ° C in a water bath for 10 minutes;

(3) After shaking well and cooling, take 1 ml of the upper liquid in a colorimetric tube, add 3 drops of reagent B dropwise, and mix well;

(4) Continue to add 3 drops of reagent C. Mix well, let stand and stratify, and observe the results.

Results Judgment: If the supernatant is colorless or shows a very light yellow color, it means that no synthetic pigment is detected in the meat sample;
