Authentication Of Vanilla Extracts Using Gas Chromatography – Vacuum Ultraviolet Spectroscopy

Vanilla is one of the most used flavoring ingredients; however, the production of high-quality vanilla extracts is expensive and therefore different attempts to adulterate this product have been reported. The main ways to adulterate vanilla extracts is the addition of synthetic vanillin, which can be synthesized using lignin, eugenol, or guaiacol, or the addition of lower quality synthetic compounds such as ethyl vanillin or coumarin, which mimic the vanilla extracts but for a cheaper price (e.g. $ 8.98 for 59...

Detecting Harmful Pathogens In Water: Characterizing The Link Between Fracking And Water Safety

Unconventional oil and gas development (UD) is the process of extracting oil and natural gas from relatively impermeable subsurface shale. Within UD, the process of hydraulic fracturing, more commonly known as ‘fracking’, is used to stimulate sequestered hydrocarbons from the target rock formations using a combination of water, sand, and chemical additives. Throughout the course of its expansion across the United States, fracking has been one of the most controversial sub-topics in the climate change debate. Industry advocates have cited...
