Temperature effect on whey protein fouling
(Sello editorial UNAD, 2024-04-18)In the present work, whey protein fouling phenomenon was studied, when fowed in the inner tube of a double tube heated by hot water which fows in the ring space between them. The fouling kinetics depends on the mass transfer effects, which is a function of protein solubility. To describe the fouling kinetics a calculus algorithm was developed, having as subsidy the protein solubility itself. The proteins solubility ... -
Editorial
