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.
