The aim of this study was to investigate the effect of sodium 4-chlorophenoxyacetate(4-CPANa) treatment on the growth of bean sprouts and its safety.The determination of 4-CPANa in bean sprouts was optimized and simulation experiment was designed.The first method was using 4-CPANa solution to soak in tap water during bean sprouts cultivation;the second method was using 4-CPANa solution to soak and cultivated by spraying tap water;the third method was 4-CPANa and water alternating spray.Then the sensory evaluation and basic growth indexes of mature bean sprouts and the residues of 4-CPANa in the sprouts were determined.The results showed that the spiked recoveries of 4-CPANa in bean sprouts were 84.67%-89.78%,the lowest detection limit was 0.05 mg/kg.The first method with 0.5 mg/L 4-CPANa and the third group with 5 mg/L all showed higher scores in color,appearance,taste,smell and texture.The total scores were 83.67 and 83.45 respectively.The first method showed better result in the yield,fresh weight,axis diameter,axis length,root weight and root length of bean sprouts.The residual amount of 4-CPANa in bean sprouts of the three treatment groups decreased with the increasing of incubation time.The conclusion is that the best quality of bean sprouts was the third method with 5 mg/L 4-CPANa:no residual of 4-CPANa was detected and no exposure risk for people.
