ABSTRACT Actualmente, las tecnologías de membranas representan una importante tendencia en el procesamiento de la leche y sus derivados. Este trabajo abordó los principales aspectos asociados con el uso de membranas en la industria láctea desde el punto de vista de los conceptos físicos fundamentales del proceso haciendo hincapié en el fenómeno del colmataje y en los tipos de membranas. Las principales metodologías de los procesos de membranas son analizadas (ósmosis inversa, ultrafiltración, microfiltración, nanofiltración). Aplicaciones industriales prácticas de las tecnologías de membranas en la concentración y fraccionamiento de los componentes de la leche fueron también discutidas. Entre ellas se estudia el aprovechamiento y tratamiento del suero lácteo; la concentración de la leche; evaluaciones microbiológicas, separación de la grasa y la lactosa; así como la eliminación de antibióticos, el tratamiento de aguas residuales, la separación de anticuerpos y concentración de inmunoglobulinas

    ABSTRACT: The application of ultrafiltration and microfiltration to protein solutions is hindered by membrane fouling that results in a decrease in the permeate flux and protein transmission with time. This review describes the evidence for fouling both on the membrane surface and within the membrane pores. The effect of the feed properties, membrane properties and the operating conditions on membrane behaviour and fouling are discussed. In ultrafiltration, fouling occurs predominantly on the membrane surface where the dynamic membrane controls membrane behaviour. In microfiltration, severe pore plugging by protein occurs, in spite of the pores being an order of magnitude larger than the protein.

    ABSTRACT: A case history of the manufacture and use of whey protein isolate is presented and particular attention is paid to the nutritional and processing characteristics of Ultra Whey 99, a whey protein isolate manufactured by Volac International Ltd. The growth of the nutritional bar market in the USA is used to demonstrate the increasing demand for specialist products such as whey protein.

    ABSTRACT: Membrane separation processes have become part of the set of basic unit operations for dairy process design and product development. These processes are employed in a variety of separation and concentration duties, but in all cases, the membranes must be cleaned regularly to remove both organic and inorganic material deposited on the surface from the fluid stream being processed. Cleaning is a vital step in maintaining the permeability and selectivity of the membrane and is necessary to return the plant to its original capacity, to minimize risks of bacteriological contamination, and to produce acceptable products. Caustic-, acidic-, and enzyme-based cleaners may be used for membrane cleaning and are usually formulated with additives to best match the specific cleaning duty. Cleaning generates significant volumes of wastewater and reduces membrane life and plant productivity, so each regime must be optimized with respect to concentration, order and duration of cleaning steps, temperature, pressure, and flow rate. This article reviews the key mechanisms governing cleaning performance and suggests directions by which further optimization may be achieved.
