科学领域:
- 食品科学 食品科学 食品科学
- 菌类毒理学 菌类毒理学
- 食品安全 食品安全
背景情况:
- 毒素A (OTA) 是一种在谷物和谷物制品 (如巴兹拉玛) 中发现的重要菌毒素.
- 人类健康面临着主要食品中OTA污染的风险.
研究的目的:
- 为了评估发酵时间,和储存对酵母面包中OTA水平的影响.
- 为了确定酸面巴兹拉玛的生产是否可以减轻OTA污染.
主要方法:
- 酸面巴兹拉玛面粉被人工污染了OTA在5和10微克/公斤.
- 样品经过发酵 (1,5小时和3小时), (300°C) 和储存 (0,5,10天).
- 使用高性能流体色谱与光检测 (HPLC-FLD) 进行了OTA量化.
主要成果:
- 储存时间对OTA水平的影响微不足道.
- 观察到OTA的总体下降,更长的发酵时间 (≥3h) 更有效.
- 在没有长时间发酵的情况下生产的巴兹拉玛超过了OTA的3μg/kg监管限制.
结论:
- 较长的发酵时间对于减少酸面巴兹拉玛中的OTA至关重要,特别是在高污染水平的情况下.
- 在发酵不足的情况下制作的酸面巴兹拉玛可能不符合OTA的安全标准.
- 优化发酵可以提高受菌毒素污染的谷物产品的安全性.

Microbial Fermentation
1
Fermentation is a crucial anaerobic metabolic process that enables microbes to derive energy from sugar without relying on oxygen or an electron transport chain. This process is fundamental to various biological and industrial applications and is classified based on the metabolic products generated.Role of Pyruvate in FermentationPyruvate and its derivatives serve as key electron acceptors in fermentative pathways. The oxidation of NADH to regenerate NAD+ is essential for the continuation of...

Real Time RT-PCR
56.9K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.

Fates of Pyruvate
8.4K
Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
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...
