水果,香料和坚果霉菌毒素纯化柱

最近,在干燥的图1和图2中存在Ochratoxin A的存在增加。来自R-BiopharmRhône的同事总结了最重要的信息。

尽管在干燥的无花果中经历了具有高发酵和高水平的黄曲霉毒素的问题,但与干燥的葡萄果不同,但是与干燥的葡萄果不同,尚未与Ochratoxin污染有关。在deed, EU regulations (1881/2006 & 2010/105) for ochratoxin A cover cereals, coffee, wine, grape juice, dried vine fruit, spices and liquorice, but section 2.2.11 dealing with ‘dried fruit other than dried vine fruit’ has remained empty since 2006, with no specified maximum limit. It is therefore very interesting to see in the first 6 weeks of 2016 there have been three consignments of dried figs from Turkey notified through the Rapid Alert System for Food & Feed (RASFF) to contain ochratoxin A with the highest level being one batch containing 52.6 μg/kg. This is five times higher than the maximum limit for ochratoxin A applied to currants, raisins and sultanas.

幸运的是,可以使用验证的方法在干燥的图中容易地监测Ochratoxin A.使用验证的方法R-BiopharmRhôneOchraprep®免疫亲和力柱与LC-荧光检测一起。然而,由于对干燥无花果的每枚托管进行了对黄曲霉毒素的常规监测,因此不仅仅是单独监测黄曲霉毒素,而是均有意义的,而是将黄曲霉毒素和Ochratoxin A分析在一起。一种经济高效和有效的方法是使用R-BiopharmRhôneFalaochraPrep®用于清理的免疫亲和性柱和单个色谱运行,两种不同的霉菌毒素之间的荧光检测开关波长。尽管有力努力降低干燥无花果霉菌毒素的发生率并通过筛选去除污染的无花果,但问题未降低,因此常规分析仍然至关重要,以确保有效的消费者保护。
