摘　　要：目的:研究二溴二甲基乙内酰脲代替二氧化氯在芒果加工消毒上的应用;二溴二甲基乙内酰脲在芒果加工中的稳定性效果及处理芒果后的残留量。方法:采用现场对比试验用二溴二甲基乙内酰脲和二氧化氯消毒芒果,检测杀灭效果;用碘量法测定消毒液中的有效溴,监测多批次加工的有效溴含量衰减速率,差量法计算最大残留量。结果:用含有效溴160mg/L的二溴二甲基乙内酰脲消毒后水样细菌总数为9.4cfu/mL,大肠菌群数为9.2MPN;含有效氯160mg/L的二氧化氯消毒后水样细菌总数为4.5×102cfu/mL,大肠菌群数为240MPN;二溴二甲基乙内酰脲在芒果连续加工11批后的平均有效溴含量下降23.08%,消毒后的最大残留量(包括消毒消耗量及自然降解部分)为3.26mg/kg。结论:二溴二甲基乙内酰脲和二氧化氯消毒水果均能符合生产要求,但是二溴二甲基乙内酰脲效果明显优于二氧化氯,可为后续加工争取更多时间,其稳定性较高,残留低,非常适用于实际生产。Objective：Use DBDMH as a disinfectant alternative tochlorine dioxide in commercial processing of mangoes; its stability and residuals in mango.Methods：Compared the efficacy of dibromohydantoin and chlorine dioxide in Mango esprocessing ; detected chlorinein disinfectant solutionwith iodometric method,monitored available bromine＇s rate of decay in multi-batch,and calculated the maximum residual.Results After using dibromohydantoin disinfectant solutioncontaining 160mg/L bromine,the total number of bacteriaand coliform bacteriadrops to 9.4cfu/mL and 9.2MPN respectively; After using chlorine dioxidedisinfectant solutionwith 160mg/L chlorine,the total number of bacteriaand coliform bacteriacomes to 4.5 102cfu/mL and 240MPN.After reused it for 11 continuous times,the bromine content fails 23.08％,the maximum residual including disinfectant solutionconsumption and natural degradation was 3.26mg/kg.Conclusion：Dibromohydantoin disinfector and chlorine dioxide both meet production requirement as disinfectant.However,the former has unique superiority：providing more availabletime for subsequent processing,higher stabilityand lower residual,therefore,it is more suitable and effective for commercial processing.
