Heat-treated biodegradable films and foils of collagen hydrolysate crosslinked with dialdehyde starch
Original language description
Gels of collagen hydrolysate (H) cross-linked with dialdehyde starch (DAS) are marked by a strong tendency to aging, which means a certain problem during their processing into biodegradable packaging materials. Applying casting technology, and drying these materials by heating air-dry films and foils for a limited time (1-4 hours) at 105 oC, may eliminate the aging problem. Solubility of heat-treated films in an aqueous environment remains preserved, but depending on how long this temperature acts and on DAS content in the film; time of film disintegration prolongs from 1-1.5 hours to 1.300 hours (about 54 days). It is probably caused by the functional groups initially blocked by sorbed water, which get released to produce hydrogen inter-chain cross-links. The decrease in glass transition temperature of such films varies with content of water sorbed in films in an interval of 90.2-189 oC.
