EDIBLE CHITOSAN-BASED FILMS WITH EUCALYPTOL ADDITION

Jestivi filmovi predstavljaju mogućnost poboljšanja kvalitete, trajnosti, sigurnosti i funkcionalnosti hrane. Mogu se koristiti kao pojedinačni ambalažni materijali, kao prevlake za hranu, nosioci aktivnih sastojaka ili imati funkciju odjeljivanja heterogenih sastojaka unutar prehrambenog proizvoda. Učinkovitost i funkcionalnost jestivih filmova ovisi o njihovim svojstvima. U eksperimentalnom dijelu ovog završnog rada ispitano je formiranje jestivog filma od polimernog hidrokoloidnog materijala kitozana s dodatkom eukaliptola kako bi se proizveo jestivi zaštitni film s poboljšanim funkcionalnim svojstvima. Otopinama kitozana određena je gustoća i prividna viskoznost, dok su pripremljenim filmovima određena fizikalna svojstva poput debljine te udjela vode i suhe tvari.Edible films represent an opportunity to improve food quality, durability, safety and functionality. They can be used as individual packaging materials, as food coatings, carriers of active ingredients or have the function of separating heterogeneous ingredients within a food product. The effectiveness and functionality of edible films depends on their properties. In the experimental part of this final work, the formation of an edible film from a polymeric hydrocolloid material of chitosan with the addition of eucalyptol was examined in order to produce an edible protective film with improved functional properties. The density and apparent viscosity of chitosan solutions were determined, while the physical films were determined by physical properties such as thickness and water and dry matter content
