Název v původním jazyce

The influence of thermal treatment on solubility of films prepared from collagen hydrolysate

Popis výsledku v původním jazyce

30 % solution of hydrolysate (w/w) was prepared from powdery hydrolysate by dissolution at 60 oC. After adjustment of pH to 11 with 15 % NaOH 10 % of starch dialdehyde (w/w, based on dried hydrolysate) was added and after its dissolution 5 % of glycerin(w/w) was dispersed. The solution was cast on a silicone plate and a film was made after evaporation of water at 35 oC for 72 hours. Samples of films of 2x2 cm were thermally treated at 60, 70, 80 and 90 oC for 24 hours and then conditioned over silica gel in a desiccator. Tests of solubility were conducted in a glass bottles where films were sunk into waster and incubated at 25 oC for a desired period of time. After solubility test the insoluble residue of film was filtered and dried to a constant weight at 103 oC for 24 hours. The amount of insoluble part was detected gravimetrically. The dependences of solubility of thermally treated films on time are graphically presented. It was found that thermal history of films significantly inf
