The primary and secondary factors of affecting the content of volatile acid were the content of SO_2, the ratio of citric acid and malic acid, the content of acid and the fermentation temperature. 影响龙眼果酒中挥发酸含量的因素主次顺序为:二氧化硫的添加量、柠檬酸和苹果酸的比例、酒醪的含酸量和发酵温度。
Quality Control of Malic Acid and Lactic Acid Fermentation During Grape Wine Making 葡萄酒苹果酸&乳酸发酵的质量控制
Because the acid content is low, the persimmon wine demends adopting measures to stop the malic acid-lactic acid fermentation. 因含酸量较低,柿子果酒需要采取措施遏止苹果酸-乳酸发酵。
And inducement of malic acid-lactic acid fermentation and proper control of redox potential during grape wine aging period could increase flavoring substances in grape wine and harmonize grape wine taste and improve grape wine quality. 还可通过诱导苹果酸-乳酸发酵和控制好葡萄酒陈酿时期的氧化还原电位来增加葡萄酒中的风味物质,协调葡萄酒的风味和提高葡萄酒的质量。
In brewing, the techniques could be used in the identification of putrefying bacteria in beer, the determination and control of MLF ( malic acid-lactic acid fermentation) in grape wine, and the detecting of biogenic amine in grape wine. PCR技术在酿酒中可用于啤酒中的腐败菌的鉴定、对葡萄酒中苹果酸-乳酸发酵(MLF)的检测和控制以及对葡萄酒中生物胺的检测。
