Abstrakt: | 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 | ||||||||||
