Separation, fractionation, concentration, and drying of food products: A technical case study
Researchers have investigated a new approach that separates juice into pulp and serum (liquid) fractions. The fractions are then processed individually and more efficiently to reduce the water content. Finally, the fractions are recombined at the site of use to obtain conventional or new products. Efforts to date have included laboratory and on-site studies of several fractionation schemes using energy-efficient membrane-based microfiltration, ultrafiltration, and hyperfiltration processes. These processes are used in combination with more conventional separation, concentration, and recombination methods such as centrifugation, vacuum evaporation, and homogenization. This technical case study provides an overview of the entire DOE/NFPA R D project and highlights the on-site testing of an advanced processing scheme for tomato juice. This scheme involves separation (centrifugation), concentration (hyperfiltration and evaporation), and recombination (homogenization) processes. The document is aimed at making field test and data analysis results available to other researchers and to private industry in a timely manner. The case study discusses project status; summarizes field testing efforts; and reviews potential technology impacts in terms of applications, energy savings, and preliminary economics.
