Methods In the process, the comparison matrix and udgment 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 udgments were found to be precise and ustifiable, and consistent with narrow marginal inconsistency ratio (0.089 for wheat flour and 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 基金项目 : (2008QK319) Fund: Supported by the Science and Technology Proect of State Quality Inspection Administration (2008QK319) * 通讯作者 :,,, long8326rong@163.com *Corresponding author: LONG Ze-Rong, Senior Engineer, Xiniang Uygur Autonomous Region Product Quality Supervision and Inspection Institute, No.188, Hebei Road (East), Urumqi , China. long8326rong@163.com
