Sess\u00e3o de Seguran\u00e7a Alimentar: Micotoxinas em insetos para alimenta\u00e7\u00e3o humana e animal, por Ronald Maul.<\/h2>\n[\/vc_column_text][vc_column_text]Com o aumento do uso de insetos como ingredientes de ra\u00e7\u00e3o e alimentos, o impacto das micotoxinas em insetos est\u00e1 sendo explorado. Depois de mostrar que a absor\u00e7\u00e3o e metaboliza\u00e7\u00e3o variam entre as micotoxinas e as esp\u00e9cie de insetos, Maul se concentrou no impacto da aflatoxina B1<\/sub>\u00a0(AFB1<\/sub>) nas larvas-da-farinha (Tenebrio molitor). As principais descobertas revelam que as larvas toleram n\u00edveis muito altos de aflatoxinas, e as acumulam pouco.<\/p>\n

Al\u00e9m disso, as larvas-da-farinha metabolizam AFB1<\/sub>\u00a0em v\u00e1rios metab\u00f3litos de fase I, incluindo novos derivados, como a AFB1\u00a0<\/sub>monohidroxilada. Enquanto isso, permanecem incertezas com rela\u00e7\u00e3o ao destino da AFB1<\/sub>\u00a0na larva-da-farinha, j\u00e1 que 87% da toxina ingerida n\u00e3o foi detectada no corpo da larva ou no res\u00edduo.<\/p>\n

Sess\u00e3o Sa\u00fade \/ Exposi\u00e7\u00e3o: Exposi\u00e7\u00e3o de curta dura\u00e7\u00e3o \u00e0s micotoxinas Fusarium deoxinivalenol and zearalenona em vacas alimentadas com uma dieta que induz a acidose ruminal, por Regiane R Santos.<\/h2>\n[\/vc_column_text][vc_column_text]A microflora ruminal tem uma certa capacidade de desativar algumas micotoxinas. Entretanto, essa capacidade \u00e9 comprometida quando a popula\u00e7\u00e3o microbiana \u00e9 afetada, por exemplo, no caso de acidose ruminal subaguda. O estudo apresentado por Santos explorou os efeitos em vacas leiteiras de uma contamina\u00e7\u00e3o de deoxinivalenol (DON) e zearalenona (ZEA) em combina\u00e7\u00e3o com uma dieta que induz a acidifica\u00e7\u00e3o do r\u00famen.<\/p>\n

Os resultados mostram que a contamina\u00e7\u00e3o por micotoxinas prejudicou a efici\u00eancia alimentar das vacas e reduziu a produ\u00e7\u00e3o de leite (rendimento e composi\u00e7\u00e3o). Al\u00e9m disso, quando o r\u00famen foi acidificado, a absor\u00e7\u00e3o de ZEA n\u00e3o foi afetada, mas a exposi\u00e7\u00e3o das vacas leiteiras ao DON e seus metab\u00f3litos aumentou.<\/p>\n

Sess\u00e3o de an\u00e1lise: Espectroscopia de IR combinada com an\u00e1lise LC-MS\/MS para triagem r\u00e1pida de micotoxinas, por Stephan Freitag.<\/h2>\n[\/vc_column_text][vc_column_text]A espectroscopia de infravermelho (IR) est\u00e1 sendo explorada para a detec\u00e7\u00e3o r\u00e1pida de micotoxinas, como uma alternativa atraente ao ELISA, que pode sofrer reatividades cruzadas e requer muitos materiais de consumo. Em seu trabalho, Freitag e sua equipe avaliaram que a espectroscopia no infravermelho pr\u00f3ximo (NIRS) \u00e9 mais relevante do que a espectroscopia no infravermelho m\u00e9dio (MIRS) quando se trata de triagem de micotoxinas. O m\u00e9todo baseia-se na abordagem quimiom\u00e9trica, rastreando altera\u00e7\u00f5es induzidas por fungos nas amostras e correlacionado com a detec\u00e7\u00e3o de micotoxinas LC-MS\/MS.\u00a0 Um modelo foi criado para an\u00e1lise de zearalenona no milho europeu e agora precisa ser validado. A previs\u00e3o de DON no trigo tamb\u00e9m est\u00e1 sendo explorada.<\/p>\n
