Protein rich extruded products were prepared from soy protein isolate and corn flour blends using a twin screw extruder and the physical properties of the extruded product were evaluated by Yu, Raman and Boye (2013). It was found that a high extrusion processing temperature with a high screw speed provides a high level of thermal and mechanical energy simultaneously, which leads to excessive structural damage and breakdown, and hence slight increase in density. irradiation affects soy proteins by causing conformational changes, oxidation of amino acids, rupture of covalent bonds and formation of protein free radicals. Through the irradiation technology, the SP1 at molecule combines with the starch molecule firmly in favor of increasing the material's capability and possessing a better exterior appearance. Irradiation was found to significantly decrease viscosity of the SPI/starch material due to the conformation change of protein molecules by oxygen radicals generated by radiolysis of water. Differential scanning calorimetry (DSC) has been used to study changes in proteins and starches as a function of temperature in s SPI-Corn starch mixtures (Li et al., 2013).It was observed that the higher amounts of SPI enhanced the thermal stability of corn starch t and raised its endothermic temperature in the mixture. On the corn starch protects the SPI from denaturation.

Flexible and transparent films from SPI and agar (AG) obtained from Gelidium sesquipedale (Rhodophyta) were prepared by thermo-molding method as well as casting (Guerrero et al., 2013 Tian et al., 2011). It was observed that the casting films possessed more homogeneous interfaces compared to the molding films, leading to their superior mechanical properties. Fig. 5 shows the tensile strength (a) and elongation at break (b) of soy proteinlagar (AG) blend films prepared from solution casting and thermomolding methods after conditioning at 43% relative humidity for 1 week.
