An investigation on the presence of mycotoxin patulin was performed on 71 apple juices and concentrates and 21 infant fruit purees purchased from retail outlets or producers in Tunisia, by reversed-phase high-performance liquid chromatography using a C18 column with UV detection at 276 nm, keeping the recovery higher than 96% for spiking levels ranging between 30 and 100 ppb. The detection limit of the method was found to be 5 ppb. The findings showed that 12% of the samples locally produced in Tunisia were contaminated by patulin, with a maximum level of 6 ppb, and 5% of the samples imported and marketed in Tunisia were contaminated at a mean level less than 6 ppb. No detectable patulin contaminations for apple cider and infant fruit puree samples were found.
采用反相高效液相色谱法，使用C18柱，在276nm波长下进行紫外检测，对从突尼斯零售商或生产商处购买的71种苹果汁、浓缩汁以及21种婴儿水果泥进行了棒曲霉素霉菌毒素检测，加标水平在30至100 ppb之间时回收率高于96%。该方法的检测限为5 ppb。结果表明，突尼斯本地生产的样品中有12%被棒曲霉素污染，最高含量为6 ppb，在突尼斯进口和销售的样品中有5%被污染，平均含量低于6 ppb。苹果酒和婴儿水果泥样品未检测到棒曲霉素污染。
