Digital images and independent components analysis in the determination of bioactive compounds from grape juice

Using a biphasic system and digital imaging analysis with chemometric tools for simultaneous determination of Cu2+ and furfural in cachaça

“…A number of studies published in the literature have reported the use of low-cost, home-built analytical instruments for in situ analyses; apart from that, miniaturized analytical tools have also been widely used to quantify a wide range of compounds in diverse samples of foods and beverages. [1][2][3][4][5][6] Sugarcane spirit (cachaça) is a Brazilian alcoholic beverage with an alcohol content ranging from 38% to 48% in terms of volume at 20 °C; this beverage is obtained from the distillation of fermented must from sugarcane juice. 7 Cachaça is a typical distilled beverage produced in Brazil; trailing just a few points behind beer, cachaça has become the second most widely consumed alcoholic beverage in the country, and is the third most widely consumed beverage worldwide.…”
