“…urea and glycerol, and it was found that low molecular weight plasticizers mix better and inhibited http retrogradation. However, reduced retrogradation resulted in loss of mechanical properties: reduced tensile strength and increased strain with moisture absorption [5,6]. The effective mixing followed by drying and film production resulted in film performance different from films produced by classic extrusion technology or solvent casting.…”

“…Urea as a low molecular weight plasticizer, showed to be a more effective plasticizer than glycerol, i.e. delivered a lower T g , a lower degree of retrogradation and a higher elongation [6]. Malic acid was identified as a strong anti-retrogradation agent as it inhibited recrystallization of starch over the full range of relative humidity levels i.e.…”

Composite films composed of biocompatible polymers are used widely in biomedical and food packaging areas. In this work, a new composite film with superior mechanical properties and biodegradability is prepared. The film is composed of biocompatible polyhydroxyethyl acrylate (PHEA) and starch, whose molecular chains are cross‐linked using sucrose polyaldehyde (SPA), a green sucrose derivative. The composite film exhibits an optimal tensile strength and tensile strain of 11.5 MPa and 147.7%, respectively, which can be ascribed to the chemical cross‐linking and hydrogen bond interactions between PHEA and starch. The tests confirm that the composite film shows satisfactory mechanical properties, hydrophilicity, and biodegradability, and thus should have wide applicability in biomedicine, food packaging, and other fields.

Different combinations of hydrophilic (glycerol and water) and amphiphilic (isoleucine) plasticizers were studied in the production of thermoplastic starch (TPS) powders and films from oxidized potato starch. All powder samples had an irregular and shrivelled morphology. In all mixtures containing isoleucine, this additive exuded from the starch matrix and re-crystallized during spray drying, resulting in hollow particles. The crystallinity and moisture sensitivity of freshly prepared films depended on the isoleucine content in the plasticizer formulation. Increasing the content led to a decrease in moisture absorption. Isoleucine formulated films showed the best tensile strength, whereas glycerol-rich ones showed better strain at break values. All glycerol plasticized formulations and the spray dried non-modified starch were amorphous. Glycerol reduced the glass transition temperature to 128°C and glycerol formulated films showed the highest moisture uptake due to its hydrophilic nature. At a relative humidity (RH) of 50%, the rate of retrogradation was low, but at RH 100% all TPS films showed a high rate of retrogradation.
