Chemical characterization of milk concentrated by ultrafiltration

Abstract: SummaryWhole milks concentrated 1·5–4-fold and acidified and citrated milks concentrated 2·8-fold by ultrafiltration at 50 °C were analysed for chemical changes relevant to further processing, storage or nutrition. Fat and protein were entirely retained in the concentrate. The retention of water-soluble vitamins, Ca, Mg, phosphate and trace minerals depended on the proportion bound to the protein. Ascorbic acid was rapidly destroyed during concentration. Because of the differential retention of nitrogenous com… Show more

“…It is well known that as the concentration takes place during ultrafiltration, the minerals associated with the proteins (such as calcium and magnesium) will increase in concentration (Green et al 1984;Premaratne and Cousin 1991). However, the extent of concentration of the cations depends on the level of association of the minerals with the protein.…”

“…Isso está de acordo com a literatura [12,21,28], segundo a qual perdas de gordura e de proteína podem ocorrer na elaboração de queijos a partir de retentado de FCV intermediário. Entretanto, apesar da perda de constituintes ter sido maior nos soros obtidos a partir de queijos elaborados com retentado, seu volume foi menor que o obtido no processo de fabricação da Mussarela Padrão.…”
