1307899 Recovering dissolved protein E C SWANSON 17 March 1970 [18 March 1969] 12797/70 Heading C3H A process for the recovery of dissolved protein from an aqueous solution also containing soluble material having a lower molecular weight than said protein consists of the consecutive steps of introducing said solution as a feed into a bed of molecular sieve material having pores of a size permitting the penetration only of molecules smaller than said protein, said bed having a thickness of from 10 to 100 millimetres, the ratio of the total volume of said solution to the volume of said bed being above 25% and no more than 65%, eluting said protein from said bed while entrapping molecules smaller in size than said protein in said molecular sieve material and recovering the protein-containing eluate. The feed may be skim milk, whey, yeast, animal blood, soy whey or fermentation media. A molecular sieve comprising crosslinked dextran having an exclusion limit between 5,000 and 30,000 molecular weight may be used.
