PCT No. PCT/DE94/00029 Sec. 371 Date Sep. 5, 1995 Sec. 102(e) Date Sep. 5, 1995 PCT Filed Jan. 14, 1994 PCT Pub. No. WO94/17107 PCT Pub. Date Aug. 4, 1994The present invention provides a process for the manufacture of a product essentially containing amylose from vegetable materials, in particular from peas. To this end, the flour is mixed with an alkaline decomposing agent, and then a separation into a liquid protein phase and a solid phase containing polysaccharide is performed. The solid phase is then re-suspended and subjected to several sifting steps, followed by at least one washing step and subsequently a drying step. From such polysaccharide material, in particular from amylose, any kind of moisture-resistent, flexible, and in particular biodegradable articles can be produced by means of conventional plastics technologies, in particular the injection molding technique. A particular advantage of the present invention resides in the fact that the thermoplastic polysaccharide material, which is produced from renewable raw materials, can also be processed into sheets which in turn can then be worked with conventional plastics techniques. |
