三标度模糊层次评判模型在食品安全风险 评估中的应用
目的 采用国家食品标准与三标度层次分析法(TAHP)对新疆小麦粉和食用植物油进行风险评估。方法 层次构建中采用三标度(0, 1, 2)定量确定各个有害物的危害程度, 并建立相应的比较和判断矩阵。通过矩阵运算获得各个危害物的权重并进行一致性检验。结果 采用TAHP在MATLAB 软件的辅助下计算各有害物的权重并检验其一致性。一致性检验结果为小麦粉为0.089, 4种植物油为0.085, 均低于0.1。利用各危害物权重因子构建的风险模型分别运用于新疆小麦粉和食用植物油2010、2014和2015年的风险评估, 结果与实际情况较为吻合。结论 该风险模型不仅可应用于上述食品质量风险评估, 而且还可推广应用于其他食品的安全评价模型的构建, 以及对食品质量安全的调查、评估和监督提供参考。
Objective To perform risk assessment of wheat flour and food-grade vegetable oil in Xinjiang region by the combination of three-scale analytical hierarchy process (TAHP) and state food standards. Methods In the process, the comparison matrix and judgment matrix were introduced firstly through making comparisons between each hazard using a 3 scale (0, 1, 2) approach. Then risk assessors could determine the weight of each hazard. Results In this paper, we utilize the above method to analyze those internal significant hazards of wheat flour and four varieties of edible vegetable oil with the auxiliary of the MATLAB software, respectively. The consistency check results showed that judgments were found to be precise and justifiable, and consistent with narrow marginal inconsistency ratio (0.089 for wheat flour and 0.085 for edible vegetable oil, respectively). The corresponding food models were constructed by using those weights, and applied to their risk evaluation during 2010, 2014 and 2015 years. The evaluation results were approximately in accordance with those of actual cases. Conclusion The technique can be used in the analysis of above-food quality risk, and it also can be used as a reference of modeling in the different food safety evaluation, as well as to provide references for survey, assessment and supervision of food quality safety.
