Large amounts of waste generated by the disposal of non-biodegradable packaging is a major concern that has stimulated the search for new materials for the development of environmentally friendly packaging. This study aims to produce cassava starch-based foams incorporated with broken rice, a co-product of rice milling. Foams were obtained by a thermopressing process, and the influence of broken rice concentration on the formulations is investigated. Broken rice addition is tested for 0 (control sample), 10, 15, 20, and 30% (w/w). Foams containing broken rice show lower thickness and higher density. With respect to water absorption capacity, the control foam and those with 10 and 15% (w/w) of broken rice addition do not present significant statistical differences for any of the tested times. Mechanical properties (tensile strain and maximum flexural stress) are positively influenced by the addition of 10% (w/w) broken rice. Foams made from formulations containing 10% (w/w) broken rice demonstrate higher tensile strain and maximum flexural stress values compared to control foams. Additionally, these foams exhibit a good appearance without superficial cracks.

“…No intuito de superar as deficiências dos materiais à base de amido, a sua mistura com outros biopolímeros tem-se mostrado uma alternativa viável. 5,6 Os hidrocoloides representam uma nova fronteira a ser explorada na busca por materiais biodegradáveis de alta eficiência. Dentre estes hidrocoloides está a pululana, uma α-glucana de origem fúngica, produzida pelo microrganismo Aureobasidium pullulan e constituída de subunidades repetitivas de maltotriose e um pequeno número de unidades de maltotetraoses, unidas por ligações α (1→6), e que se apresenta como um material compatível em misturas com o amido.…”

BIODEGRADABLE FILMS OF CASSAVA STARCH, PULLULAN AND BACTERIAL CELLULOSE. The largest consumption of plastics in the world is referred to the synthetic polymers, which are not biodegradable and have a non-renewable source, generating a large environmental impact, especially in urban centers. As a result, in the last two decades several polymers obtained from renewable sources (biopolymers) have been studied as potential raw materials for the production of new biodegradable materials with different applications. The objectives of this study were to produce biodegradable films based on cassava starch, pullulan and bacterial cellulose, and also to characterize these films according to their microstructure, barrier, thermal and mechanical properties. The addition of bacterial cellulose and pullulan to the starch films resulted in films with more homogeneous surfaces, and also decreased solubility and water vapor permeability, and increased elongation and thermal stability.

“…Recently, it has being used as primary material for building biodegradable materials due to its abundance and low cost. Although raw granular starch is widely available, its physical properties compromise its use when plastic property is desirable, therefore the study of starch plasticity in non-food application has been receiving greater attention in recent literature [2][3][4] , Still, the knowledge of starch mixing properties is still needed.…”

Characterization of cassava starch processed in an internal mixer

et al. 2013

An internal mixer connected to a torque rheometer was used to investigate the effect of moisture content (13.2 to 46.8 g.100g -1 ), rotation speed (13.2 to 46.8 rpm) and processing temperature (53.2 to 86.8 °C), applying a factorial central composite design, on the specific mechanical energy (SME), pasting viscosity and crystallinity of cassava starch. Torque values were highly significant for the three variables, showing decrease with increasing moisture, temperature and rpm. The highest cold viscosity (CV) was obtained at 13.18 g.100g -1 moisture, 86.87 °C and 30 rpm due to increased rupture of starch granules caused by processing at lower moisture condition. Peak viscosity (PV) values were higher than CV values which indicated that the processing was not able to destroy completely the molecular integrity of the starch granules. Smaller setback (SB) at high temperature and rpm and low moisture showed possible starch depolymerization causing loss of recrystallization capacity. Processing under low moisture content resulted in reduction of crystallinity. The results showed that the effect of moisture was more pronounced than rotation speed and processing temperature of cassava starch.
