Cellulose fiber enhances the physical characteristics of extruded biodegradable cassava starch foams

Considering the importance of cassava starch for Brazilian industries, the current work aimed at evaluating the effects of extrusion parameters on the physical characteristics, mainly viscosity properties of extruded cassava starch. A factorial central composite design (2³) with three independent variables and the response surface methodology were used to evaluate the results of expansion index, specific volume, water absorption index, water solubility index, color and paste properties, according to the variations in the moisture content, barrel temperature and screw speed. Results indicated that barrel temperature influenced the expansion index, specific volume, water absorption index, all the color parameters, the initial viscosity, peak and final viscosity. Feed moisture influenced the specific volume, color parameters, final viscosity and retrogradation. The screw speed had effects on water absorption index, color components as well as on the final viscosity and retrogradation of extruded starch. High moisture, low screw speed and intermediate temperature provided lower starch degradation, which is desirable for pre-cooked starch.

Properties Of Composites

Cassava pulp (CP) is an inexpensive and broadly available waste by-product from cassava starch production. This by-product is basically constituted of cellulose fiber and residual starch. In this study, cassava pulp was mixed with natural rubber (NR) with various contents using two roll mills to obtain CP/NR composites. Natural rubber grafted glycidyl methacrylate (NR-g-GMA) was used as compatibilizer in CP/NR/NR-g-GMA composites. Sulfur conventional vulcanization was used. The composite specimens were prepared by compression molding. Mechanical properties and morphological properties of composites were investigated. The results showed that tensile strength was significantly increased with increasing content of cassava pulp up to 20 phr. However, when cassava pulp was increased more than 30 phr, tensile strength was slightly decreased. Elongation at break of NR composites was not changed with increasing cassava pulp. The modulus of NR composites was increased with increasing cassava pulp content. Morphological properties of CP/NR composites was elucidated as well.
