【導讀】種來生產(chǎn)濃縮蘋果汁。曲霉素含量的影響進行了調(diào)查。葡枝河被認為是富馬酸和乳酸中最主要的病原體。植物乳桿菌引起的L-蘋果酸。的顯著減少，表明乳酸發(fā)酵的進行。在這個復雜的生化途徑中，植物乳桿菌還形成。青霉產(chǎn)生的唯一的棒曲霉素，但并不影響延胡索酸和乳酸含量。除蒸發(fā)過程外整個加工過程中，樣品中的富馬酸含量都下降了。只在蒸發(fā)過后增加，是因為熱量的供應。酸含量也呈下降的趨勢。水果和果汁中的微生物所產(chǎn)生的代謝產(chǎn)物會導致某些質(zhì)量缺陷和健康問題。這些代謝物的存在是被果汁的質(zhì)量標準普遍接受的。殘留，因此棒曲霉毒素的含量可作為經(jīng)過加工的果汁和水果一項質(zhì)量指標。馬酸的存在被認為是一個摻假跡象。每個蘋果至少要有五處進行接種針接種。反轉(zhuǎn)前后，Luff-Schoorl是為了糖的處理而產(chǎn)生的。有結(jié)果都以單強度的蘋果汁°糖度表示。在預防棒曲霉素的形成方面起到重要的作用。在這項研究中，接種試驗微生物和孵。化后都沒有進行清洗或處理。
