虫胶防腐涂料是一种水果表面涂被剂,可增加果面光泽,在一定时期内可减少水分蒸发,加入多菌灵(MBC)和2、4-D(MCP)后,还有减少腐烂的作用,对防止果皮皱缩,保持风味,降低损耗,延长贮藏期,效果显著。但用这种涂料处理过的水果,会有少量多菌灵和2、4-D残留于水果中。经测定;苹果中多菌灵残留量为0．29~1．7ppm2．4-D为0．43~ Shellac anti-corrosion coating is a kind of fruit surface coating agent, which can increase the luster of fruit surface and reduce water evaporation in a certain period. After adding carbendazim (MBC) and 2,4-D (MCP), it also reduces decay. The effect of preventing peel shrinkage, maintaining flavor, reducing loss, prolonging the storage period, the effect is remarkable. However, a small amount of carbendazim and 2,4-D remained in the fruits treated with this coating. It was determined that the carbendazim residue in apples was 0.29~1.7ppm 2.4-D was 0.43~
