小麦粉比对检验结果的分析

Analysis of wheat flour on the inspection test results

目的通过分析比对检验的结果,找出企业在检验技术和管理等方面存在的差距和不足,保证企业化验室数据的准确性,防止在检验过程中由于系统误差、操作不当导致错误的检验结果,确保企业化验室在控制食品质量安全中起到应有的作用。方法各实验室按照国家标准对小麦粉灰分进行测定,提交检验的原始检验记录和检验报告,对企业提交的报告进行数据汇总,先利用格鲁布斯检验法对离群值进行剔除,然后对数据用统计法进行分析和评价。结果运用统计方法对泰兴市小麦粉比对检验的结果进行分析,有2个实验室数据离群。结论小麦粉生产企业检验方面存在一些问题,对少数企业灰分检验结果偏离较大的现象进行了探讨,对实验室在检测过程控制、检测结果评价等方面提出了改进建议。

Objective To find out the existing gaps and deficiencies in the aspects of inspection technology and management, by analyzing and comparing the test results, to ensure the data accuracy in the enterprise laboratory, thus to prevent the incorrect results due to system error and improper operation of the inspection process, to ensure that the laboratory of the control in enterprises can play its role in food safety. Methods The laboratories determined the ash content in wheat flour in accordance with national standards, and submitted the inspection of the original test record and report to the company, then the reports were submitted to the Inspection Institute and the data were collected, the outlier was removed using Grubbs test method, and then the data were processed by statistical analysis and evaluation. Results Inspection results of wheat flour in the city of Taixing by using the statistical method above were analyzed, and 2 laboratory showed to be outlier. Conclusion Analysis of inspection to the major problems of wheat flour production enterprises was put forward, and the phenomenon of ash test results deviation in a few enterprises was discussed, and the suggestions for improving the laboratory control and the process of testing result evaluation were presented.
