有机酸对不同温度下湿啤酒糟青贮发酵及好氧稳定性的影响

郭志强，陈志强，陈志强，2010。有机酸对不同温度下湿啤酒糟青贮发酵及好氧稳定性的影响。Bulg。j·阿格利司。科学。研究了不同温度下有机酸对湿啤酒谷物青贮微生物学及好氧稳定性的影响。青贮样品在1.0 l厌氧罐中青贮，在室温(20℃)或高温(30-37℃)下，添加和不添加有机酸。青贮45天后，青贮进行好氧稳定性试验，室温和高温(30-37℃)。在20-30°C培养的样品中，酵母和霉菌数量最高，CO 2产量最多。有机酸对湿啤酒青贮的好氧稳定性有显著影响，特别是在30℃时，有机酸对湿啤酒青贮具有较高的抑菌活性。在45 d厌氧期间，有机酸降低了酵母和霉菌的数量，提高了37℃下的好氧稳定性
