Ternary potato starch-furcellaran-gelatin film – a new generation
of biodegradable foils (in English)

Polimery 2017, No 9, 673


DOI: dx.doi.org/10.14314/polimery.2017.673

Summary

Foils were prepared from potato starch (S), furcellaran (F) and gelatin (G) (S/F/G foils) using glycerol as a plasticizer. Their mechanical properties, aqueous solubility, water content, water uptake, enzymatic hydrolysis, and thermal (DSC) properties were determined. The 0.16 mm thick foil has ~ 80 MPa mechanical resistance with an elongation at break of 27.8 %. The aqueous solubility and water uptake of the S/F/G foils reached 35 % and 145 %, respectively. The S/F/G foils were susceptible to hydrolysis with polysaccharide enzymes such as glucoamylase and Viscozyme L (a blend of arabanase, cellulase, β-glucanase, hemicellulase and xylanase), as well as trypsin, a proteinase.
