Abstract
Hrana je človeška potreba, ki je nujno potrebna za preživetje. Zaradi tega jo je treba ceniti in preprečiti, da bi se po nepotrebnem zavrgla. Eden od glavnih krivcev za velike količine zavržene hrane so insekti, ki okužijo pakirano hrano. V naši raziskavi smo se osredotočili na težavo insektov v embalažah testenin. Namen magistrskega dela je bil izdelati kartonsko, deloma lepljeno embalažo iz enega kosa, ki predstavlja izboljšavo na trgu trenutnih embalaž za testenine. Magistrsko delo obravnava proces načrtovanja, izdelave ter testiranja embalaže za pakiranje testenin z izboljšano odpornostjo na vdore insektov. Poleg lastne izdelave embalaže smo se povezali še s podjetjem Aki Izlake, ki je za nas izdelalo dva tipa embalaž, s katerimi smo preverjali zaščito hrane (testenin) pred vdori insektov. V teoretičnem delu je predstavljeno področje embalaže na splošno, od zgodovine, materialov do njenih funkcij. Predstavljeno je prav tako stanje raziskav na področju trenutnih embalaž za testenine in analize le-teh pred vdori insektov. Večina raziskav kot glavno snov za zaščito pred insekti uporablja rastlinska eterična olja, ki so zdravju neškodljiva in prav tako učinkovita, vendar na trgu še nerealizirana. V eksperimentalnem delu smo izvedli naše načrtovanje ter izdelali svojo embalažo za testenine. Za izdelavo je bilo treba izbrati primeren material, za izbiro katerega smo opravili testiranje na več vzorcih ter na koncu izbrali najtrpežnejšega. Ko je bil material izbran, smo embalažo izrisali v programu ter jo na rezalniku izrezali. Izdelano embalažo smo, skupaj z različnimi vzorci embalaž, testirali na Univerzi Molise v Italiji, kjer so testirali odpornost embalaž na vdor insektov, in sicer koruznega žužka. Analiza odpornosti je trajala 15 dni. Kot je bilo ugotovljeno, je bila naša embalaža uspešna na testiranju, saj je vanjo vdrlo manj insektov kakor v originalno, trenutno embalažo testenin, ki je na trgu. Naša embalaža torej dokazano prinaša izboljšave na področju zaščite testenin pred vdori insektov.

Title:Improvement of food packaging from insect attacks
Abstract:
Food is humanity's necessity, and it’s essential for surviving. For that it needs to be appreciated and we should prevent food waste. One of the main reasons for huge food loses are insects that infest packaged food. In our research we focused on problem of insects in packaged food. This master's thesis includes the process of planning, construction and testing of improved pasta packaging. In addition to making our own pasta packaging, we got in touch with company Aki Izlake, and asked them to make a sample of packaging they produce. We wanted to compare it with ours and test anti insect capabilities of both. In theoretical section we presented general information about packaging, everything from history, to materials used and functions it has. After that we have presented the state of current research in field of anti-insect packaging. We included scientific articles from some of the world's most renowned researchers in this area of expertise. Research of anti-insect packaging mainly focuses around plant's essential oils as the main substance to prevent insects from infesting packaged food. In the experimental section we realized our plans and we constructed our own pasta packaging. To do this, we firstly had to select the most appropriate material for construction. We prepared several different tests for three samples of cardboard, and at the end we selected the most durable one. After material was selected, we drew a blueprint of packaging in the software and we cut it on a digital cutter. Packaging samples were tested at University of Molise in Italy, in order to test packaging resistance to insect penetration. The analysis of anti-insect resistance lasted for 15 days. As it was discovered, our packaging proved successful at the test, as less insects were able to penetrate it than the original pasta packaging. This result proves that our packaging brought an improvement to the field of anti-insect pasta packaging.
