摘要： A variety of plant materials adopted for processing into, e.g., low-calorie vegetable fibers and dietary flours, are bleached by (1) soaking a plant material having a moisture content of up to 50% at a temperature ranging from 20.degree. to 100.degree. C. with an aqueous solution containing an alkaline agent and more than 100 g/l of hydrogen peroxide, and having a pH of at least 8.5, such that the aqueous solution is completely absorbed by the plant material without establishing any liquid phase; (2) heating the soaked plant material at a temperature ranging from 40.degree. to 100.degree. C. for a period of time sufficient to effect the bleaching, and washing the bleached plant material with water and drying it.

摘要： A process for bleaching a lignocellulosic matter in the form of a mechanical, thermomechanical, chemicomechanical or chemicothermomechanical papermaking pulp, or of wood chips while being converted into one of these pulp types by processing in a machine consisting essentially of two interpenetrating spiral surfaces wound around parallel shafts driven in synchronous rotation in the same direction inside a barrel which encloses them, and determining between upstream and downstream in the direction of forward travel of the matter a series of zones for drawing and braking the matter, which comprises combining a bleaching treatment using a reducing agent and a bleaching treatment using an oxidizing agent, characterized in that, after pretreatment using at least one metal-complexing or sequestering agent, the lignocellulosic matter undergoes a washing operation with an efficiency greater than 96% before undergoing in succession a bleaching treatment using a reducing agent at a pH of between about 8 and 12, a washing operation to remove the reducing agent and a bleaching treatment using an oxidizing agent.
