Abstract
A process for pigments such as the treatment of proteinic solutions containing heminic groups or chlorophylls in view of their decolorization, and products thus obtained. The proteinic solution is subjected in a first step, to a slight enzymatic hydrolysis, preferably with acid pH pepsin, and the partially hydrolyzed solution is then brought to a temperature above 60.degree. C., at an acid pH between 2 and 4.
Claims16
A process for decolorizing a proteinic solution containing as pigment heminic or chlorophyll colored groups, comprising subjecting said proteinic solution to enzymatic hydrolysis to provide a partially hydrolyzed solution comprised of partially hydrolyzed protein and separated colored groups, adjusting the pH of said partially hydrolyzed solution to between 2 and 5 with sulfuric acid, and subjecting the resulting acidified solution to a temperature above 60.degree. C. to improve the fluidity of the partially hydrolyzed solution and to trigger the agglutination of said colored groups.
