Essential oils are natural antimicrobial agents that can be used to control fungal and mycotoxin contamination. Although there are numerous reports discussing the fungal and mycotoxin contamination of foods, there are few researches on baby food contamination so this work aimed to determine the fungal and mycotoxin contamination in cerelac, cornflakes and milk powder and tried to control the mycotoxigenic strain growth and their production of mycotoxins by using essential oils. Cornflakes were heavily contaminated (24 species including 9 genera), while cerelac and milk powder were less contaminated. Aspergillus and Penicillium were the prevalent genera. The produced aflatoxins and ochratoxins from the tested strains of Aspergillus flavus and A. niger were extracted and estimated by fluorometric method. We used the 18S rRNA sequence technique to identify the genotypes of the three isolates. Two isolates were identified as Aspergillus niger and the third isolate as A. flavus. Omt‐A gene was detected in the A. flavus, while Aopks gene was detected in A. niger isolates. Amongst the five used essential oils, only cumin and peppermint oil depressed the mycotoxigenic strain growth and peppermint oil had the highest result. Its inhibitory effect on aflatoxin and ochratoxin production was evaluated. Aflatoxin production was highly reduced by 52.1%, but ochratoxin inhibition was very low, 4.88% and 3.17% by A. niger obtained from cornflakes and milk powder, respectively. The three tested samples were contaminated by ochratoxins, but cerelac and milk powder samples were free of aflatoxins. Cornflakes sample recorded the highest reading for both toxins.

精油从婴儿食品中分离出的产毒曲霉菌株

香精油是天然抗微生物剂，可用于控制真菌和霉菌毒素污染。尽管有许多报道讨论了食品中真菌和霉菌毒素的污染，但有关婴儿食品污染的研究很少，因此这项工作旨在确定小脑，玉米片和奶粉中的真菌和霉菌毒素的污染，并试图控制致毒毒素菌株的生长及其致病性。使用精油生产霉菌毒素。玉米片受到严重污染（24种，包括9属），而cerelac和奶粉受到的污染较小。曲霉属和青霉属是普遍的属。从测试的黄曲霉和米曲霉菌株中生产黄曲霉毒素和曲霉毒素提取黑曲霉并通过荧光法估计。我们使用18S rRNA序列技术来鉴定这三个分离株的基因型。两个菌株被鉴定为黑曲霉和第三分离为A. flavu秒。在黄曲霉中检测到Omt‐A基因，而在黑曲霉分离物中检测到Aopks基因。在这五种使用过的精油中，只有孜然和薄荷油抑制了产毒菌株的生长，而薄荷油的效果最高。评估了其对黄曲霉毒素和曲霉毒素产生的抑制作用。黄曲霉毒素的产量大大降低了52.1％，但是曲霉毒素的抑制率很低，分别为4.88％和3.17％。黑曲霉分别从玉米片和奶粉中获得。这三个测试样品均被och曲霉毒素污染，但Cerelac和奶粉样品中不含黄曲霉毒素。玉米片样品记录了两种毒素的最高读数。
