RECENT DEVELOPMENTS IN PROTEIN RECOVERY AND PURIFICATION.

This study deals with emerging techniques for the purification of proteins, with an emphasis on those methods which have potential for scale-up. These include membrane processes, some new adsorption and affinity techniques, supercritical gas extraction, 2-phase aqueous liquid/liquid extraction, and electrokinetic methods. Many are at an early stage of development for their use in the food industry. However, it is likely that in the future they will broaden substantially the options available for processing both 'solid' and 'liquid' streams. Significant and sustained research and development will be needed to convert these techniques to 'off-the-shelf' established technologies.
