基于决策树排序的挂面中潜在危害物质风险分析
目的 对挂面中潜在危害物质风险进行分析, 对最相关的危害物质进行危害程度排序。方法 基于全国2015~2017年的挂面危害物检测数据, 利用决策树法将挂面潜在危害物质进行排序。建立了3个决策树, 分别对污染物、食品添加剂和生物毒素进行排序。将监测物质分为高、中、低优先级, 以利于在风险评估时确定优先考虑的次序。结果 根据对挂面抽检结果的风险分析, 铅、铝、二氧化钛和乙二胺四乙酸二钠、黄曲霉毒素B1和脱氧雪腐镰刀菌烯醇为高优先级检测物质, 而柠檬黄、日落黄、诱惑红和亮蓝、苋菜红、胭脂红为中优先级检测物质。结论 决策树方法有助于对挂面中潜在危害物质的风险优先级排序, 可以作为建立基于风险的监测计划的工具。该方法具有可拓展性, 可以利用最新监测数据, 对其他类型粮食的风险等级进行评估, 得到其潜在危害物质的优先次序物质清单。
Objective To analyze the risk of potential hazardous substances in vermicelli and rank the most relevant hazardous substances. Methods Based on the nationwide detection data of vermicelli hazard from 2015 to 2017, the potential hazard substances in vermicelli were sorted by the decision tree method. Three decision trees were established to rank pollutants, food additives, and biotoxins respectively. The monitoring substances were divided into high, medium and low priority, so as to determine the priority in risk assessment. Results According to the risk analysis of the results of the random inspection of the noodles, lead, aluminum, titanium dioxide, disodium EDTA, aflatoxin B1 and deoxynivalenol were the high priority detection substances, while lemon yellow, sunset yellow, alluring red and bright blue, amaranth and carmine were the medium priority detection substances. Conclusion The decision tree method is helpful to rank the risk priority of potential hazardous substances in vermicelli, and can be used as a tool to establish risk-based monitoring plan. The method is extensible, and can use the latest monitoring data to assess the risk levels of other types of food to obtain a list of priority substances for potential hazardous substances.
