【摘要】：目的調(diào)查安徽省部分地區(qū)2015年產(chǎn)小麥真菌污染情況,為評估糧食中真菌侵染及真菌毒素污染狀況、進(jìn)一步開展預(yù)測微生物學(xué)研究提供依據(jù)。方法采集安徽省五地市2015年產(chǎn)未經(jīng)儲存的小麥籽粒,進(jìn)行感官檢查和千粒重計(jì)數(shù)。采用點(diǎn)種法將麥粒樣品接種于含0.1 g/L氯霉素的馬鈴薯葡萄糖瓊脂(PDA)平板,于(28±1)℃培養(yǎng)5 d后,進(jìn)行菌落計(jì)數(shù)和菌種鑒定。結(jié)果感官檢查顯示,每份小麥樣品均檢出數(shù)量不等的赤霉病粒,范圍在8.0%~20.0%之間,千粒重平均值范圍在39.8~48.5 g之間,且赤霉病粒率與千粒重水平呈負(fù)相關(guān)(r=-0.98)。安徽省五地市小麥樣品的真菌污染率為100.0%,且均以交鏈孢霉為主要污染菌。結(jié)論安徽省五地市2015年產(chǎn)小麥赤霉病粒率較高,真菌污染狀況較嚴(yán)重,有必要對小麥中的真菌毒素進(jìn)行檢測,并結(jié)合我國人群小麥及其制品的消費(fèi)情況,評估居民通過食用小麥及其制品暴露真菌毒素的風(fēng)險。
[Abstract]:Objective to investigate the fungal contamination of wheat in some areas of Anhui Province in 2015, so as to provide a basis for the assessment of fungal infection and mycotoxin contamination in grain and the further study of microbiology. Methods the unstored wheat grains were collected from five cities of Anhui Province in 2015. Sensory examination and 1000 grain weight count were performed. Wheat grain samples were inoculated into potato glucose Agar (PDA) plate containing 0.1 g / L chloramphenicol and cultured at (28 鹵1) 鈩，
