Resumo: | Mycotoxins are secondary metabolites produced by some filamentous fungi that have toxic properties. The main way of exposure to that toxin is usually through the ingestion of contaminated food even if it is in small quantity but continuously it can induce to its accumulation in the body and cause an intoxication, affecting many organs and systems, especially the liver, kidneys and the nervous system. The most detected mycotoxins are produced by fungi from the genus Apergillus, Penicillium and Fusarium. The raisins are products obtained from the partial loss of water from the ripe fruit by drying, presenting high content of sugar and low activity of water, fact that favors the growth of fungi, principally A. niger and A. carbonarius which produce resistant spores to processing. This study aimed to achieve the isolation and identification of fungi which produce the mycotoxin and its respective toxins in dark raisins in bulk and packaged in the commercial establishment itself using microculture methods and thin layer chromatography. Thepresence of A. niger and Penicillium spp were detected, the first ones being producers of ocratoxina and A. flavus, the producer of aflatoxina. Therefore the research showed the contamination by toxigenic fungi in the collected samples in 82% of the evaluated establishments. |

A principal via de exposição a essa toxina é normalmente através da ingestão de alimentos contaminados, mesmo que sejam em pequenas quantidades, mas de forma contínua podem levar ao seu acúmulo no organismo podendo causar uma intoxicação e afetando muitos órgãos e sistemas, principalmente o fígado, rins e sistema nervoso. As micotoxinas mais frequentemente detectadas são produzidas por fungos dos gêneros Aspergillus, Penicillium e Fusarium. As uvas passas são produtos obtidos a partir da perda parcial da água da fruta madura por secagem, apresentando alto teor de açúcar e baixa atividade de água, fato que favorece o crescimento de fungos, principalmente A. niger e A. carbonarius que produzem esporos resistentes ao processamento das mesmas. Este estudo teve por objetivo realizar o isolamento e identificação de fungos produtores de micotoxinas e suas respectivas toxinas em uvas passas escuras a granel e embaladas no próprio estabelecimento comercial, utilizando os métodosde microcultivo e cromatografia em camada delgada comparativa. Foram detectadas a presença de A. niger, Penicillium spp e A. flavus, os primeiros, produtores de ocratoxinas e o último de aflatoxinas. Portanto, a pesquisa demonstrou a contaminação por fungos toxigênicos nas amostras coletadas em 82% dos estabelecimentos avaliados.Revista Brasileira Multidisciplinar - ReBraM2015-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistarebram.com/index.php/revistauniara/article/view/34710.25061/2527-2675/ReBraM/2015.v18i1.347Revista Brasileira Multidisciplinar - ReBraM; v. 18 n. 1 (2015): Janeiro-Junho; 179-1882527-26751415-3580reponame:Revista Brasileira Multidisciplinarinstname:Universidade de Araraquara (UNIARA)instacron:UNIARAporhttp://revistarebram.com/index.php/revistauniara/article/view/347/314Santos, Ana FernandesSilva, Yasmim MartinsRezende, CátiaJordão, Christiane de Oliveirainfo:eu-repo/semantics/openAccess2018-03-08T14:24:47Zoai:ojs.revistarebram.com:article/347Revistahttp://revistarebram.com/index.php/revistauniaraPRIhttps://revistarebram.com/index.php/revistauniara/oairevistauniara@uniara.com||2527-26752527-2675opendoar:2018-03-08T14:24:47Revista Brasileira Multidisciplinar - Universidade de Araraquara (UNIARA)false |
