Su'esu'ega fa'asaienisii luga o le gaosiga, tulaga lelei ma le faʻaogaina o ata tifaga / biodegradable i le gaosiga o meaʻai na faʻatinoina e le tele o vaega suʻesuʻe i le lalolagi atoa ma ua lipotia i lomiga suʻesuʻe.5-9.O le tele o pisinisi ma le siosiomaga e mafai ona maua i le vaega o ata / pa'u e mafai ona 'ai/biodegradable e masani ona faamamafaina.5,10,11ma le tele o lomiga na faʻatatau i mataupu e fesoʻotaʻi ma mea faʻainisinia, femalagaiga kesi, ma aʻafiaga o isi mea i luga o nei meatotino, e pei o le ituaiga ma mea o loʻo i totonu o plasticisers, pH, susū vavalalata ma le vevela ma isi.6, 8, 10-15.
Peitai,su'esu'e i ata e mafai ona 'aina/fa'aletinoo lo'o i ai pea i lona tamameamea ma su'esu'ega i luga o fa'aaogāga fa'apisinisi o ata e mafai ona 'aina/biodegradable ua fa'ateleina le fa'alogo i tausaga talu ai, peita'i, o lo'o fa'atapula'aina lava.
Tagata su'esu'e io le Vaega o le afifiina o Mea'ai, Matagaluega o Mea'ai ma Mea'ai Fa'asaienisi, University College Cork, Aialani, ua atia'e le tele o galuega, biopolymer-based, edible/biodegradable films i nai tausaga talu ai.
Ole tapula'a ole afifiina
E masani lava, e fa'atapula'a le fa'aogaina o ata tifaga ona o latou uiga fa'aletino.Mo se faʻataʻitaʻiga, o ata tifaga e tasi, lipid-faʻavae e iai mea lelei e puipuia ai le susu ae leai se malosi faʻainisinia23.O le mea la lea, na fausia ai ata laminated e ala i le pipii faatasi o ata biopolymer se lua pe sili atu.Ae ui i lea, o ata laminated e sili ona lelei i ata e tasi, biopolymer e faʻavae i le emulsion ona o lo latou umiaina o mea faʻaleleia atili.O le fausiaina o fausaga laminated e mafai ona foia nei faaletonu e ala i le inisiniaina o ata e mafai ona 'aina/biodegradable ma le tele o laulau aoga.
Ata tifaga ma fa'alavalavafa'avae i polotini solu vai e masani ona solu i le vai ae o lo'o iai le okesene lelei, lipid ma le tofo o mea pa'u.O polotini e galue e pei o se matrix faʻapipiʻi, faʻatulagaina i faiga faʻapipiʻi tele, e maua ai ata tifaga ma faʻapipiʻi ma mea faʻainisinia lelei.Lipid, i le isi itu, e fai ma pa puipui susu lelei, ae e leaga le kesi, lipid ma le tofo.E ala i le tuʻufaʻatasia o polotini ma lipids i le emulsion poʻo le bilayer (o se membrane e aofia ai le lua mole mole), e mafai ona tuʻufaʻatasia uiga lelei o mea uma e lua ma faʻaitiitia mea leaga.
Mai su'esu'ega na faia e leVaega o Mea'ai Mea'aii le UCC, o uiga masani o ata tifaga e mafai ona 'ai/biodegradable e fa'apea:
- O le mafiafia o mea'ai/biodegradable ata tifaga gaosi mai le 25μm i le 140μm
- O ata tifaga e mafai ona manino, manino, ma fa'afefe pe opaque e fa'atatau i mea o lo'o fa'aogaina ma le faiga o lo'o fa'aogaina
- O ituaiga ata tifaga tuai i lalo o tulaga fa'atonutonu o le siosiomaga na fa'aleleia atili ai mea fa'ainisinia ma mea fa'alava kesi
- O le teuina o ata i se tulaga fa'anofonofo (18-23°C, 40-65 pasene RH) mo le lima tausaga e le'i tele se suiga i uiga fa'atulagaina.
- O ata tifaga e faia mai mea eseese e mafai ona faigofie ona faʻapipiʻi faʻatasi
- O ata gaosi e mafai ona fa'ailoga, lolomi pe fa'amaufa'ailogaina
- O suiga laiti i le fa'atulagaina o ata tifaga (fa'ata'ita'iga o le vaeluaga o le biopolymer) e a'afia ai meatotino
