Abstract

Twenty two mycotoxins in 136 durum wheat collected from Tunisia in 2020 and 2021 were investigated. Mycotoxins were analyzed by UHPLCMS/MS. In 2020, 60.9% of the samples were contaminated with Aflatoxin B1 (AFB1) and/or enniatin. Whereas, in 2021, 34.4% were contaminated by enniatins. AFB1 was detected only in 2020, in the continental region (6/46) and all samples exceeded limits. AFB1 was detected in stored wheat (24-37.8 µg/kg) but also in pre-stored wheat (17-28.4 µg/kg) and in one sample collected in the field (21 µg/kg). Enniatin A1, enniatin B and enniatin B1 were detected in wheat collected in the field (30-7684 µg/kg), pre-storage (42-1266 µg/kg) and storage (65.8-498.2 µg/kg) from the continental region also, in sample collected in pre-storage (31.3-1410 µg/kg) and at harvest (48- 1060 µg/kg). Samples had a water activity less than 0.7 and moisture content ranged between 09-14%. AFB1 level represent a health risk to the Tunisian consumers.

突尼斯两个气候区2020年和2021年采集的硬粒小麦籽粒采前和采后多重真菌毒素的发生情况

对2020年和2021年在突尼斯采集的136粒硬粒小麦中的22种真菌毒素进行了调查。采用UHPLCMS/MS对真菌毒素进行分析。2020年，60.9%的样品被黄曲霉毒素B1 (AFB1)和/或enniatin污染。而在2021年，34.4%的植物被多年生植物污染。AFB1仅在2020年检测到，在大陆地区(6/46)，所有样本均超标。贮藏小麦中检测到AFB1(24-37.8µg/kg)，预贮藏小麦中检测到AFB1(17-28.4µg/kg)，田间样品中检测到AFB1(21µg/kg)。在大陆地区田间采集的小麦(30-7684µg/kg)、贮藏前采集的小麦(42-1266µg/kg)和贮藏后采集的小麦(65.5 -498.2µg/kg)、贮藏前采集的小麦(31.3-1410µg/kg)和收获时采集的小麦(48- 1060µg/kg)中均检测到Enniatin A1、Enniatin B和Enniatin B1。样品的水活度小于0.7，水分含量在09-14%之间。AFB1水平对突尼斯消费者构成健康风险。

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.
