Abstract

The natural co-occurrence of aflatoxins (AFs) and ochratoxin A (OTA) in liquorice roots obtained from different herbal outlets of Karachi, Pakistan, was evaluated. A total of 60 samples were obtained during 2019‒2021 and analysed using HPLC with fluorescence detection. The method was validated according to the European Union (EU) regulation. The incidence of AFs was 52 in all tested samples (87%), with a contamination range of 1.2‒6.4 µg kg^-1 and an average of 2.1 ± 0.3 µg kg^-1. In all samples, the AFs contamination was below the maximum limit (ML) of 10 µg kg^-1 for total AFs as set by the EU. The OTA contamination in all samples ranged 1.5‒60.3 µg kg^-1, with a mean of 18.9 ± 0.8 µg kg^-1. In 36 samples (60%) the OTA contamination was below the ML of 20 µg kg^-1 as set by the EU. These results led to the recommendation to test liquorice root on mycotoxins, as it comes to food quality standards.

甘草中黄曲霉毒素和赭曲霉毒素A的天然共生。

对从巴基斯坦卡拉奇不同草药产地获得的甘草根中黄曲霉毒素（AF）和赭曲霉毒素A（OTA）的天然共生进行了评估。在2019-2021年期间，共获得了60个样本，并使用荧光检测的HPLC进行了分析。该方法根据欧盟（EU）法规进行了验证。所有测试样本中AF的发生率为52（87%），污染范围为1.2-6.4 µg kg-1，平均2.1 ± 0.3 µg kg-1。在所有样本中，AF污染均低于10的最大限度（ML） µg kg-1，用于欧盟规定的总AF。所有样品中的OTA污染范围为1.5-60.3 µg kg-1，平均18.9 ± 0.8 µg kg-1。在36个样品（60%）中，OTA污染低于20的ML µg kg-1，由欧盟规定。这些结果导致了在食品质量标准方面建议对甘草根进行真菌毒素检测。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
