Chemical and biochemical bleaching of oat hulls : The effect of hydrogen peroxide, laccase, xylanase and sonication on optical properties and chemical composition
Oat hulls are an excellent dietary fibre source for food supplements due to their rich lignocellulose composition as well as their great abundance as low-value agricultural side stream. For the production of white fibre supplements, a mild, but effective bleaching of the hulls is required. Chemical bleaching with hydrogen peroxide and sodium hydroxide was here found to be a suitable method increas
