Effective recovery and purification of bioproducts is an important aspect in the commercialization of bioproducts. Downstream processing of bioproducts is an effort-intensive and high-cost operation due to the complexity of the crude feedstock and the necessity to retain their bioactive state. Aqueous two-phase system (ATPS) has been proposed as a useful technique for the separation, purification and concentration of biomolecules. ATPS is a biphasic (liquid-liquid) system that mainly composed of aqueous solution, which is suitable for the preservation of native structure of purified biocompound. Moreover, ATPS retains the advantages of conventional liquid-liquid extraction such as high productivity, simplicity, short processing time, cost-effectiveness, scalability and versatility. ATPS becomes even more attractive and competitive when it utilizes inexpensive phase-forming chemicals and phase-recycling processes that greatly reduce the cost of bioprocessing or become more environmental friendly. This webinar will demonstrate the use of ATPS in recovering valuable bioproduct from food waste. The design of ATPS protocol as simplified and rapid recovery method will also be covered.
