Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
This chapter focuses on the recent advances in the use of membrane processes for the recovery of biologically active compounds (BACs) from agro-food products and by-products. The fundamentals of typical membrane operations, as well as of membrane preparation, are firstly presented. Then, typical case studies for the recovery of polyphenols, peptides, carotenoids and tocopherols are presented and discussed. Multistep membrane processes for the separation, purification and concentration of BACs from their original sources are specifically designed based on laboratory experimental data. These processes provide concentrated fractions for the formulation of functional foods within a biorefinery strategy, with significant economic and environmental advantages over conventional methodologies.
Keywords:
Agro-food production, Biologically active compounds, Functional foods, Membrane separation.
