Impact of roasting conditions on physicochemical, taste, volatile, and odor-active compound profiles of Coffea arabica L. (cv. Yellow Bourbon) using electronic sensors and GC-MS-O using a multivariate approach.

This study examined the impact of different roasting temperatures on the chemical composition and flavor of coffee beans. Roasting at 150℃ resulted in increased compounds but decreased umami and sourness. Roasting at 210℃ increased flavonoids and caffeine but also produced aldehydes, ketones, sulfur compounds, and pyrazines. Analysis showed separation of beans based on roasting temperature and time.

Evaluating repellence properties of catnip essential oil against the mosquito species Aedes aegypti using a Y-tube olfactometer.

Researchers tested the effectiveness of catnip essential oil in repelling Aedes aegypti mosquitoes, which are vectors for diseases like dengue and yellow fever. Even at low concentrations, the oil repelled more than 70% of mosquitoes for one to four hours, making it a potential natural alternative to synthetic repellents.
