Název v původním jazyce

Studying solubility of biodegradable films prepared from collagen hydrolysate

Popis výsledku v původním jazyce

Biodegradable films were prepared by casting from 50 % solution of hydrolysate (w/w) cross-linked with starch dialdehyde (DAS). DAS was dosed 0, 2, 4, 6, 8 and 10 % based on weight of hydrolysate. 30 g of hydrolysate was dissolved in 100 ml of water at 60 oC and after adjustment of pH to 11 with 1 N NaOH starch dialdehyde was added. The solution was cast on a silicone plate and the film was made after evaporation of water at 30 oC for 72 hours. Test film samples measuring 2 by 2 cm were cut and conditioned over silica gel in a dessicator for 2 and/or for 15 days. Solubility test were conducted in a glass bottles where test film samples were covered with water and incubated at 37 oC for a desired period of time. After the prescribed dissolution time thenon-dissolved fraction of the test film sample was separated by filtration, dried at 103 oC to a constant weight and weighed. The dependences of dissolved film sample fractions on time of dissolution with various amounts of DAS are prese
