Abstract:
... The aim of this study was to evaluate the effects of process conditions on the solid–liquid extraction of bioactive compounds from the Alicante Bouschet grape skin from the semi-arid region of Brazil. The influence of temperature (23–57 °C), ethanol concentration (16–84%) and citric acid concentration (0–4%) on the total phenolic content, monomeric anthocyanin content and on the antioxidant capaci ...

Abstract:
... Wines with a clear geographical origin are an issue of interest for consumers and food industries. This paper presents a data mining study of Merlot wines from South America to identify the fingerprint of their geographical origin. A group of samples from Argentina (n = 17), Brazil (n = 12), Chile (n = 48), and Uruguay (n = 6) was analyzed. Twenty chemical compounds were determined by high-perform ...
