For creation of high-quality and economic bioplastics researchers turned to various sources of raw material, such, as com starch, capola, castor oil, soya fiber and so on. Plastics polyols on the basis of soy bean used for carpet coverings are already developed and produced now. Technologies for producing bioplastics on the basis of soy oil, and also new...

Model protein samples. Isolated soya protein (Purina Brand Assay Protein RP 100 ) was employed in these studies and found to contain on a dry matter basis 96% crude protein, 1.4% ash, 0.2% crude fiber, and 2% N-free extract. This material was used to prepare 48 samples, which were heated in airtight metal containers ( 250-ml ) at temperatures of 90, 110, 130° C for 0.5, 1, 2, and 4 h respectively. 

These regenerated proteins are obtained from milk (casein), soya beans, corn, and peanuts. More or less complex chemical separation and purification processes are required to isolate them from the parent materials. They may be dissolved in aqueous solutions of caustic, and wet-spun to form fibers, which usually require further chemical...

Plants are very attractive and potential sources of cellulose primarily because they are abundant and relatively cheap to harvest. Cellulose can be extracted from lignocellulosic fibers, which are available aU over the world. A wide variety of plant materials like cotton, ramie, sisal, flax, wheat straw, tubers, sugar beet, soya bean, etc., are known for cellulose microfibril production. Wood is another main important source of extracting cellulose fibrils, where cellulose microfibrils were reinforced by intracellular amorphous materials made of hemicelluloses, lignin, resin, etc. Extraction of pure cellulose microfibrils from these lignocelluloseic materials involves chemical treatments such as alkali extraction and bleaching. 

Substances of organic origin, such as wood flour, used for consumption products and in the production of electrical insulation cellulosic fibers (textiles, paper fibers and particles) used mainly to increase impact resistance fruit shell flour, which increases the fluidity of plastic materials under pressing and enhances the dielectric properties and appearance of final products protein flour—casein and soya flours for example—used with carbamides. 

Wang et al. extracted cellulose nanofibres from soybean stock by chemo-mechanical treatments with diameter ranging from 50-100 nm and size of -1000 nm (2007). The cellulose nano fibers were dispersed in polymeric matrix of poly (vinyl alcohol) (PVA) and polyethylene (PE) by addition of dispersant ethylene-aciylic oligomer. The soya bean stock based PVA films showed an increase of 4-5 fold in tensile strength.
