Williams Pear Canning-Industrial Residues Suitable for Powdered Products: Effect of Particle Size and Acid Immersion on Physicochemical and Bioactive Properties.

ABSTRACT: Powdered fiber- and polyphenol-rich ingredients derived from pear canning residues were obtained by direct processing. Residues were subjected to acid immersion and subsequent convective drying, milling, and sieving. Drying kinetics were studied to select the best operative drying conditions (70 °C, 3 h) for both acidified (CIT) and non-acidified (C) samples. Two granulometries were also assessed (<210 and <590 μm). The resulting powders (C210, CIT210, C590, CIT590) were characterized as bioactive compounds, techno-functional fiber properties, physical and stability attributes, as well as in vitro bioaccessibility. All powders were rich in dietary fiber (52-54%) and exhibited a polyphenol content ranging from ~390 to 567 mg GAE/100 g on a dry basis for CIT and C powders, respectivel
