The mechanical stability of soy protein plastics is correlative to its water absorption.

Present situation of research and potential application of soybean protein plastic;

Discussion of grafting treatment of soybean protein-modified PAN fiber;

The assay studied that on soybean protein extractions in four reverse micelles,the conditions are firstly compared with the size of“water pool”,the extraction rate of protein,and the subunits of protein by electrophoresis experiment.

The analytical methods of soybean protein components and subunits reported in the literature were reviewed as the following:(1) 2S,7S,11S and 15S were four components of soybean protein separated with ultracentrifuge and among them,7S and 11S were major components.

Viscosity model of soy protein dough;

Influence of processing variables on system variables in twin-screw extrusion of soy protein;

Summary of the study of soy protein degradable materials;

In order to overcome these shortcomings, various kinds of modification the protein have been explored extensively: that are heated and alkali?acid modification?reducing agent treatment? cross-linking?auxiliary of addition?filled in modification etc to enhance the mechanical processing property, In order to get the protein plastics of soybean with pract.

This paper discusses variety of degradation plastics, biodegradable mechanism, present situation of studys for degradable plastics with soy protein and protein plastics degradability.

This paper summarized the research contents and progress of protein plastics ,including the kind of protein , the degradation principle of protein biodegradable plastics,modifying methods and the preparation techniques .

The results show that the tensile strength and Young modulus of the protein plastic are increased from 9.
