Izraba agroživilskih ostankov kot surovine za izdelavo trajnostne papirne galanterije = Valorisation of agri-food residues for the production of sustainable paper accessoriesSežun, Mija ...Agroživilski rastlinski odpadki so zaradi visoke vsebnosti lignoceluloze in velikih količin fenolnih spojin primerni za valorizacijo v embalažnih materialih. Ti materiali lahko ponujajo papirni ... industriji konkurenčne prednosti kot specializirani embalažni materiali, kar jim omogoča uporabo nizkocenovnih surovin za izdelavo po meri visokokakovostne proizvodnje. V našem prispevku se osredotočamo na proizvodne ostanke različnih rastlinskih tokov (pridelava in predelava čebule, oljk in granatnih jabolk), da pokažemo, kako bi lahko tako raznolike agroindustrijske biološke odpadke izkoristili že pred uporabo v papirni industriji. Tako čebulne lupine kot oljčni listi so pokazali visoko antioksidativno aktivnost in sposobnost obnavljanja visokih donosov bioaktivnih kemikalij (približno 100 mg kvercetina ali oleuropeina na g suhega ekstrakta). Količina antocianinov v lupini granatnega jabolka pa je bila skromna (približno 0,3 mg antocianinov na g suhega ekstrakta). Kar zadeva izdelavo papirja, opazimo, da je papir izdelan iz omenjenih tokov medsebojno popolnoma drugačen, tako na videz kot tudi, kar zadeva optične in mehanske lastnosti. Oljčne liste in čebulne ostanke smo uporabili samostojno, medtem ko je bilo treba granatnemu jabolku dodati komercialna celulozna vlakna. Izdelani papirji imajo dobre tehnološke lastnosti ter nenavadno teksturo in videz, kar kaže, da bi jih lahko uporabili za izdelavo posebnega papirja.Source: Papir : revija Društva inženirjev in tehnikov papirništva. - ISSN 0350-6614 ([Letn.] 49, [št.] 26, 2021, str. 37-40)Type of material - article, component part ; adult, seriousPublish date - 2021Language - slovenianCOBISS.SI-ID - 92756995
