Abstract

Jestivi filmovi i prevlake imaju potencijal za primjenu pri pakiranju proizvoda ribarstva. S obzirom na njihove karakteristike, jestivi filmovi i prevlake djeluju kao barijera za migraciju tvari poput vode, kisika i CO2 te mikroorganizama između proizvoda i okoline. Uz navedeno, u sastav jestivih filmova i prevlaka moguće je dodati i različite funkcionalne sastojke čime se postiže produljena trajnost, poboljšanje tehnoloških i organoleptičkih svojstava gotovog proizvoda. S ekološkog aspekta, primjena jestivih filmova i prevlaka prihvatljiva je i poželjna budući da se njihovom primjenom smanjuje upotreba sintetičkih ambalažnih materijala koji su jedan od vodećih uzroka onečišćenja okoliša. S obzirom da se sirovine za izradu jestivih filmova i prevlaka mogu dobiti preradom biootpada iz različitih industrija, njihova primjena uklapa se u koncept održivog razvoja koji teži odgovornom i racionalnom iskorištavanju prirodnih resursa.

Abstract (english)

Edible films and coatings have the potential of being used in seafood packaging industry. Given their characteristics, edible films and coatings act as a barrier between the product and different substances from the environment such as water, oxygen, CO2 or different microorganisms. In addition, it is possible to add various functional ingredients to edible films and coatings in order to prolong durability or improve technological and organoleptic properties of the final product. From an environmental point of view, the use of edible films and coatings is not only acceptable but also desirable because their use reduces the use of synthetic packaging materials which are one of the leading causes of environmental pollution. Considering the fact that the raw materials used for the production of the edible films and coatings can be obtained by processing bio-waste from different industries, their applications fits into the concept of sustainable development wbicb seeks to use natural resources responsibly and rationally.
