2、據(jù)分析的精確性。[結(jié)果]最終得到碭山梨酒發(fā)酵的較優(yōu)方案是:1000g梨加500g水榨汁,發(fā)酵時間4d,接種酵母活化液6.0%,發(fā)酵溫度26℃,葡萄糖添加量14%,在此條件下,酒精度可達到10%。[結(jié)論]安徽碭山梨產(chǎn)量約占全國梨總產(chǎn)量的13%,利用碭山梨發(fā)酵生產(chǎn)碭山梨酒是增加碭山梨加工品種、緩解鮮果儲存壓力、降低果品浪費、提升果品價值的有效途徑之一。關(guān)鍵詞碭山梨;液態(tài)發(fā)酵;梨酒;正交試驗設(shè)計中圖分類號S609.9文獻標(biāo)識碼A文章編號o517—6611(2014)l8—05974—03StudyonProductionProcessofDangshanPea
