Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a protein-removed natural rubber latex, by which the natural rubber latex having an extremely small protein content and not causing a side reaction, when used as an industrial raw material, can be produced in a large amount at a low cost. SOLUTION: This method for producing the protein-removed natural rubber latex is characterized by adding a protein-denaturing agent selected from the group consisting of urea compounds and NaClO to a natural rubber latex to denature proteins in the latex, and then removing the denatured proteins. A desired urea compound includes urea, a lower alkyl urea, or a urea double salt. COPYRIGHT: (C)2004,JPO
