Abstract
Extracted vegetable pulps are bleached to a high degree of whiteness, thus rendering them more attractive as food supplements, by (a) treating such pulp in an acid medium at a pH of up to 2.5 and for a period of time of at least 10 minutes, (b) next washing the pulp thus treated to an efficiency of at least 80%, and (c) then reacting the washed pulp with an aqueous alkaline solution of hydrogen peroxide, in the presence of an H.sub.2 O.sub.2 stabilizer.
