nature : biochemical products refers to the separation and purification process technology and technology. Biological products (such as fermentation) or obtained by the enzyme catalytic purification products have many special problems. The first product to maintain the biological activity, it is generally not high temperature, the use of low-temperature conditions, and also avoid an excessive acids and alkali, mechanical activity caused by the loss of factors; Secondly product ingredients are often more complex, high-purity product was often used to a variety of technologies, more experienced Step complex purification steps. With modern physics, chemical and electronic, and computer technologies in the life sciences, the application of new efficient separation medium, the separation of technical and analytical testing out different methods layer, a tremendous impetus to the biochemical separation project to the modernization and automation direction. Because biological processes of product separation at the stage of the process behind it biochemical separation project also called downstream biochemical engineering (downstrean biochemical engineering).
