摘要
目的系统评价基质辅助激光解吸/电离飞行时间质谱法(matrix-assisted laser desorption/ionization time of flight mass spectrometry,MALDI-TOF-MS)检测食源性致病菌有效性.方法使用计算机检索中国期刊全文数据库、万方学术期刊全文数据库等数据库中通过MALDI-TOF MS鉴定食源性致病菌的相关文献.采用Review Manager 5.4软件进行Meta分析.结果MALDI-TOF-MS鉴定的有效性低于食品安全国家标准的传统培养法.结论MALDI-TOF-MS技术具有操作简便、高效的特点,在食品检验中值得推广应用,但仍然需要纳入更多高质量的文献做进一步证实.
Objective To analyze and study the quality of packaged drinking water inspection results and existing problems in Chengdu area from 2020 to 2022.Methods According to GB 19298—2014 National food safety standards—Packaged drink water,the color,turbidity,state,taste,odor,residual chlorine(free chlorine),carbon tetrachloride,chloroform,oxygen consumption,bromate,volatile phenols,cyanide,anionic synthetic detergents,and coliform bacteria of packaged drinking water of 68 enterprises were sampled and analyzed from 2020 to 2022.Results There were more unqualified batches of packaged drinking water in Chengdu during the 4 months of production from May to August,and the index of Pseudomonas aeruginosa was mainly unqualified.Conclusion Packaged drinking water in Chengdu is more susceptible to contamination by Pseudomonas aeruginosa during high-temperature seasons.It is recommended that packaged drinking water production enterprises improve the qualification rate of packaged drinking water by standardizing production processes,scientifically disinfecting,strengthening their own supervision,and avoiding production during high temperature seasons.
