Biodegradability and mechanical properties of starch films from Andean crops

Immunological properties of Andean starch films are independent of their nanometric roughness and stiffness

“…Other Andean Native starch films used as cell plating substrates, like T- Previous work reported elsewhere has provided data for other mechanical properties of these native starch films [20]. It is worth noting that the values of the elastic modulus obtained from AFM measurements presented here are in agreement with the values obtained from previous uni-axial tensile tests performed in this laboratory and reported by Torres et al [20]. The tensile elastic modulus found for native starch films ranged 15 -106 MPa.…”

“…Finally, the resulting starch was dried at 40°C for 48 h and stored in a desiccator at room temperature.2.2 Preparation of starch filmsStarch films were prepared by casting. The procedure reported by Torres et al[20] was used. Briefly, starch was mixed with distilled water to form a 5% (w/w) starch solution.This solution was partially hydrolyzed in diluted hydrochloric acid (0.1 N) adjusting pH to 2.0.…”

Influence of incorporation of starch nanoparticles in PBAT/TPS composite films

“…However, although PBAT is a promising material for the production of environmentally friendly biodegradable polymers, it presents two important disadvantages: its higher cost and slower biodegradability. The PBAT degradation time, about 4 months, is similar to that of poly(lactic acid) and higher than that of thermoplastic starch . In order to reduce the cost of the final product and accelerate its degradation, to make it more competitive, several researchers have studied PBAT blends with other biodegradable polymers …”

Characterization of antioxidant-antimicrobial κ-carrageenan films containing Satureja hortensis essential oil

“…To solve this problem, much research has aimed to obtain an environmentally friendly packaging material [1,2]. Recent decades have seen extensive investigation into biodegradable coatings or films prepared from biopolymers, including proteins, polysaccharides and lipids or their combinations.…”
