Projekat

Razvoj novih inkapsulacionih i enzimskih tehnologija za proizvodnju biokatalizatora i biološki aktivnih komponenata hrane u cilju povećanja njene konkurentnosti, kvaliteta i bezbednosti (MPNTR - 46010)

Sažetak

Cilj ovog rada je da se ispita uticaj različite koncentracije glicerola i guar-ksantana na osobine dvoslojnog filma na bazi pogače uljane tikve golice (PuOC) i kukuruznog zeina, kao i da se pronađe optimalna koncentracija ovih aditiva koja će dati filmove sa najboljim mehaničkim i barijernim osobinama. Različite koncentracije glicerola (30%, 40% i 50%) i guar-ksantana (0,1%, 0,3% i 0,5%) su dodate u PuOC sloj, dok je sastav zeinskog sloja ostao nepromenjen. Dobijeni rezultati pokazuju da najbolje mehaničke osobine ima film sa najmanjom koncentracijom glicerola (30%) i najvećom koncentracijom guar-ksantana (0,5%). Filmovi su pokazali lošiju barijeru prema vodenoj pari, a dobijene vrednosti su tipične za biopolimerne filmove. Međutim, svi ispitivani filmovi su pokazali veoma dobru barijeru za O2 (brzina propustljivosti manja od 50 ml/m2/danu na 1 bar). Sa druge strane, sa povećanjem koncentracije dodatih aditiva, došlo je do povećanja brzine propustljivosti CO2.
