| 摘 要： | 大麦在制麦过程主要的污染霉菌为镰刀霉、烟曲霉和根霉.小试制麦的植菌试验表明,霉菌污染量在102个/g麦芽,PYF平均值为84.3%;霉菌污染量在103个/g麦芽,PYF平均值为70.7%,都会引发PYF;霉菌污染量在104个/g麦芽,PYF平均值为107.8%,不会引发PYF;镰刀霉和根霉的影响大于烟曲霉的影响. |

| Abstract: | The contaminant mould in wort preparation process of barley mainly include Fusarium, aspergillus .fumigutus and rhizopus. The small-scale bacteria-plant test suggested that PYF occurred as the contaminant capacity of mould was 10^2 particle/g, malt and PYF average value was 84.3 % or the contaminant capacity of mould was 10^3 particle/g, malt and PYF average value was 70.7 %, and PYF would not occur as the contaminant capacity of mould was 10^4 particle/g, malt and PYF average value was 107.8 %. Fusar/um and rhizoaus had worse effects on PYF than aspergiUus fumigatus. |
