    • Bioactive compounds and total antioxidant capacity of cane residues from different grape varieties 

      Ferreyra, Susana Gisela; Antoniolli, Andrea; Bottini, Rubén; Fontana, Ariel (Comité editorial Journal of the Science of Food and Agriculture, 2019-10-08)
      BACKGROUND Every year, the viticulture activity generates considerable amounts of underused lignocellulosic residues as grape cane, which are generally composted or burned despite their potential value as a source of bioactive compounds. Determination of their phytochemical composition and total antioxidant capacity (TAC) may be a useful way of exploiting different high‐added value applications. RESULTS Twenty‐one phenolic compounds (PC) and two carotenoids (Car) were quantified by high performance‐liquid chromatography‐diode array detection in eight grape varieties from different locations ...

    • Phenolic and sensory profiles discriminate geographical indications for Malbec wines from different regions of Mendoza, Argentina. 

      Urvieta, Roy; Buscema, Fernando; Bottini, Rubén; Fontana, Ariel (Comité Editorial Food Chemistry., 2018-11-01)
      Malbec wines from 27 parcels from the three most important winemaking regions of Mendoza, Argentina, were produced under standardized winemaking conditions, and analyzed for phenolic composition and by means of sensory descriptive analysis. Different methods of characterization and cluster analysis for each data matrix showed that some locations of Mendoza could be significantly separated from each other. The results of unsupervised statistical methods were compared using a test for similarities and divergences, also showing that different locations may be associated. The current report is the ...
