摘要： The present invention is directed to a method for debittering protein hydrolysates and to a debittered protein hydrolysate product. In the method, an aqueous solution of a protein hydrolysate is provided. The solution is passed through a bed of phenolic resin particles. A first portion of the solution is collected as it exits from the bed. The first portion contains a non-bitter fraction of the protein hydrolysate. After collection of the first portion of non-bitter protein hydrolysate, a second portion of the protein hydrolysate is collected as it exits from the bed. The second portion contains a bitter fraction of the protein hydrolysate.
