Abstract
The process is used to recover protein from solns. emulsions or dispersions esp. from milk and lactoserum, botd. from cheese or casein mfre. Process enables recovery of the protein which is suitable for use in human food prepns. The protein is not denatured. Previous process suing carboxymethyl cellulose required a high degree of substitution to obtain high recoveries (i.e. it must be above 0.7 to give a recovery of above 80%. The process uses carboxymethyl starch substd. to a lower degree of substitution to obtain high recoveries. The complex prod. formed is novel.
