用*Enterococcus faecalis* 07发酵豆蛋白分离物 (PPI),通过减少苦味和增强umami,显著改善了它的味道. 这个过程改变了挥发性化合物,使PPI更适合食品应用.
科学领域:
- 食品科学与技术 食品科学与技术
- 微生物学 微生物学
- 感官科学 感官科学
背景情况:
- 豆蛋白分离物 (PPI) 具有高营养价值,但具有不良的豆香味,限制了其在食品中的应用.
- 改善口味对于扩大使用植物性蛋白质,如PPI,至关重要.
研究的目的:
- 评估Enterococcus faecalis* 07发酵在改善PPI的感觉和物理化学特性方面的有效性.
- 分析发酵时间对PPI的风味特征的影响.
主要方法:
- 使用*E. faecalis* 07的PPI发酵时间为0,24,48,72小时.
- 分析pH值,活细胞数量,自由氨基酸,电子舌头数据和挥发性有机化合物 (VOCs).
主要成果:
- 发酵显著降低了PPI的苦味,增加了umami的强度.
- 确定了64种挥发性有机化合物,其中减少了六,1-octen-3-ol和trans-2-octenal,并产生了和.
- 相关性分析将VOC的变化与五种味觉 (苦味,酸味,甜味,味,乌玛米) 的变化联系起来.
结论:
- *Enterococcus faecalis* 07发酵是一种可行的方法,可以增强豆蛋白分离物的感觉属性和物理化学特性.
- 发酵有效地改变了PPI的风味特征,解决了其特有的豆味.

Fermentation
Fermentation is a type of metabolic process that occurs in the absence of oxygen, where organic molecules such as glucose are broken down to produce energy. During this process, the...

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
