Plants have developed sophisticated mechanisms to survive in dynamic environments. Plants can communicate via volatile organic compounds (VOCs) to warn neighboring plants of threats. In most cases, VO...
Characterizing volatile metabolites in raw Pu’er tea stored in wet-hot or dry-cold environments by performing metabolomic analysis and using the molecular sensory science approach
生普洱茶 代谢组学分析 干冷环境 湿热环境 气味标记
2023/4/20
The aroma profile of raw pu’er tea (RPT) depends on its storage duration (2–10 years) and storage conditions (wet-hot or dry-cold environment). We analyzed the major odorants of RPT samples by perform...
Influence of Eurotium cristatum and Aspergillus niger individual and collaborative inoculation on volatile profile in liquid-state fermentation of instant dark teas

2023/4/20
The three instant dark teas were produced from instant green tea (IGT) by liquid-state fermentations using the microorganisms Eurotium cristatum (EFT), Aspergillus niger (AFT), and sequential inoculat...
Effects of supplementing vitamin E on in vitro rumen gas production,volatile fatty acid production,dry matter disappearance rate,and utilizable crude protein
vitamin E rumen fermentation in vitro
2015/9/15
Two in vitro trials were carried out to study the effects of supplementing vitamin E (VE) on rumen fermentation. In Trial I, four levels of VE product (purity 50%), i.e. 0, 15, 30, and 60 mg/kg dry ma...
