Edible packaging materials : bachelor thesis

Sama ideja o upotrebi jestivih zaštitnih filmova već duže vrijeme zaokuplja pažnju znanstvenika. Postupak prevlačenja hrane bilo voskovima ili želatinom patentiran je daleke 1800. godine. Jestivi filmovi nalaze se u upotrebi već niz godina (želatina, kapsule, ovitci za kobasice, prevlake od čokolade, šećera i od voska). Funkcija jestive ambalaže je ponuditi selektivnu prepreku za usporavanje migracije vlage, transporta plina, migracije ulja i masti te transporta otopljene tvari; poboljšati mehanička svojstva rukovanja hranom; poboljšati mehanički integritet ili osobine rukovanja hranom; zadržavati hlapljive spojeve okusa i nositi aditive za hranu poput antioksidansa i antimikrobnih sredstava. U ovom završnom radu objašnjeno je što je jestiva ambalaža, njezine vrste, svojstva kao i sama svrha primjene. U budućnosti se očekuje povećanje upotrebe jestivih materijala, njihov razvoj te poboljšanje svojstava.The idea of using edible protective films has long captured the attention of scientists. The process of coating food with wax or gelatin was patented as far back as the 1800s. Edible films have been used for many years (gelatin, capsules, sausage casings, chocolate, sugar and wax coatings). The function of edible packaging is to offer a selective barrier to retard the migration of moisture, gas transport, oil and fat migration and solute transport; improve the mechanical handling properties of foods; improve the mechanical integrity or handling characteristics of the food; retain volatile flavor compounds and carry food additives such as antioxidants and antimicrobials. In this bachelor thesis, it is explained what edible packaging is, its types, properties as well as the purpose of application. In the future, it is expected to increase the use of edible materials, their development and improved properties
