"The work deals with modeling solubility of biodegradable films prepared from collagen hydrolysate. To this purpose, it studied the effect of added plasticizer, cross-linking agent or additional thermal annealing on dissolution rate of films; experiments were planned through factor tests of 23 type. Basis for preparing films was a 15-% (w/v) solution of hydrolysate with various additions of plasticizer ? glycerol, GLY, in quantities of 0, 5 and 10% (related to hydrolysate dry matter, w/w), cross-linking agent ? dialdehyde starch, DAS, in quantities of 0, 4 and 8% (related to hydrolysate dry matter, w/w). Films were prepared by casting solution on silicon plates with subsequent evaporation of solvent (water) in 72 hours at 35 oC. A part of films was subjected to additional thermal annealing at 62.5 and 90 oC. Solubility tests on films were performed in water at 25 oC. Percentage of dissolved film was determined through gravimetry. Results of film solubility were assessed statistically and graphic models" . . "94" .
