O a fa'avasegaga o ata afifiina o mea'ai?

Auaata tifaga afifi meaaiei ai meatotino sili ona lelei o le puipuia lelei o le saogalemu o meaʻai, ma o lo latou manino maualuga e mafai ona faʻamatagofieina le afifiina, o ata tifaga meaʻai e faʻateleina le taua i le afifiina o oloa. Ina ia mafai ona faʻafetaui le suiga o le siosiomaga i fafo ma manaʻoga o tagata faʻatau eseese, o le tele o kamupani i le salafa o le lalolagi ua faʻateleina a latou suʻesuʻega ma atinaʻe taumafaiga i ata afifiina meaʻai.

1. Ata afifi lautele

I le taimi nei e masani ona faʻaaogaina meaʻai faʻapipiʻi ata e aofia ai: PVA faʻapipiʻiina pa puipui ata, biaxially oriented polypropylene ata (BOPP), biaxially oriented polyester ata (BOPET), nylon ata (PA), lafo polypropylene ata (CPP), aluminized ata tifaga, ma isi. e fa'aaogaina lautele ona o latou fa'atinoga sili ona lelei, manino lelei, maualuga le malosi o le malosi, fa'apitoa o kesi ma vai fa'atasi ma le tau maualalo o le gaosiga.

2. Ata afifiina mea'ai

O ata faʻapipiʻi meaʻai e faʻatatau i meaʻai, e masani lava o mea faʻapitoa macromolecular e pei o lipids, proteins ma polysaccharides, faʻaopoopo i mea faʻapipiʻi meaʻai, mea faʻafesoʻotaʻi, ma isi, faʻafefiloi e ala i aʻafiaga faʻaletino, ma faʻagaoioia e ala i auala eseese o le gaosiga O le ata na faia. E tusa ai ma uiga o mea mataʻina autu o loʻo faʻaaogaina, e mafai ona vaevaeina ata tifaga i ni vaega se fa: ata tifaga edible carbohydrate, ata tifaga edible protein, lipid edible films, ma ata tifaga edible composite. O ata tifaga e mafai ona faʻaaogaina ua faʻaaogaina lautele i le olaga i aso faisoo, e pei o le pepa araisa masani masani o loʻo faʻaaogaina i lole lole, ipu faʻapipiʻi saga mo aisakulimi, ma isi, o mea uma e masani ona faʻaogaina. Fa'atusatusa i mea fa'apipi'i fa'apipi'i, e mafai ona fa'aleaga ata tifaga e aunoa ma se fa'aleagaina. Faatasi ai ma le faʻaleleia atili o le faʻalauiloaina o le siʻosiʻomaga o tagata, o ata tifaga e mafai ona vave avea ma nofoaga autu o suʻesuʻega i le tulaga o le afifiina o meaʻai ma maua ai ni faʻaiʻuga.

3. Antibacterial afifi meaai ata tifaga

Antibacterialata afifi meaaiose ituaiga o ata tifaga e iai le malosi e taofia pe tape ai siama i luga ole laiga. E tusa ai ma le tulaga o le antibacterial, e mafai ona vaevaeina i ni ituaiga se lua: tuusao antibacterial ma le tuusao antibacterial. E maua sa'o le antibacterial e ala i le fa'afeso'ota'i sa'o i le va o mea fa'apipi'i o lo'o iai mea fa'ama'i ma mea'ai; antibacterial le tuusao e masani lava e faaopoopo nisi o mea i le ave e mafai ona fetuutuunai le microenvironment i totonu o le afifi, poʻo le faʻaaogaina o le filifilia o mea faʻapipiʻi e pulea microorganisms. Fa'atupulaia, e pei o le ata fa'apipi'iina o le atemosifia.

4. Nanocomposite afifiina ata

Nanocomposite ata tifaga e faasino i se mea ata tifaga tu'ufa'atasia faia e vaega ma fua i luga o le faasologa o nanometers (1-100nm) faʻapipiʻi i matrices eseese. O lo'o i ai le lelei o mea tu'ufa'atasi masani ma mea fa'aonaponei fa'aonaponei. Ona o le aʻafiaga i luga, le aʻafiaga o le voluma, le tele o le aʻafiaga ma isi uiga e mafua mai i le fausaga faʻapitoa o ata nanocomposite, o latou mea faʻapitoa, mea faʻainisinia, mea antibacterial, mea pa puipui ma isi vaega o loʻo i ai uiga e le maua e mea masani, e faʻaaogaina ai. i mea'ai. E faʻaaogaina lautele i le afifiina, e le gata ina ia fetaui ma manaʻoga o le faʻalauteleina o le fata o meaʻai, ae ia mataʻituina foi suiga lelei o meaʻai i totonu o le afifi.

5. Biodegradable afifiina ata

O lenei ituaiga ata e masani ona foia ai le faafitauli e faigata ona toe faʻaaogaina nisi mea e le mafai ona faʻaleagaina. O le tanuina i lalo o le eleele o le a faaleagaina ai le fausaga o le eleele, ma o le susunuina o le a maua ai kasa oona ma mafua ai le filogia o le ea. E tusa ai ma le faiga o le faʻaleagaina, e masani ona vaevaeina i ata faʻapipiʻi ata ma ata faʻapipiʻi biodegradable.

Talu ai o ata fa'aleagaina e fetaui ma mana'oga mo le puipuiga o le si'osi'omaga, o lea ua su'esu'eina lautele nei ma ua tosina atu i ai tagata su'esu'e eseese. E tele mea fou e fa'aleagaina ma fa'alelei le si'osi'omaga ua fausia, e pei o polymers e faia mai mea mata masoa e fa'aaoga ai mea fa'afouina o la'au (e pei o sana). Lactic acid (PLA), o se palasitika polypropylene carbonate (PPC) faʻafeiloaʻi faʻafeiloaʻi mai le carbon dioxide ma le propylene oxide e fai ma mea mata, ma chitosan (chitosan) maua mai le deacetylation o chitin, lea e maua lautele i le natura. . O nei meafaitino ua faʻaitiitia; o mea fa'apitoa, manino, ma le iila i luga e le'o atoatoa fo'i ona fa'aleagaina. E le gata ina fetaui ma le maualuga o le manino o ata afifiina, ae o loʻo i ai foi se sao malosi i le faʻaleleia o le siosiomaga, ma e tele faʻamoemoega talosaga.

Ae ui i lea, e taua le taʻua o ata tifaga meaʻai e sili atu ona manaʻomia i luga o le tumama ma le saogalemu o mea faʻapipiʻi, ma e manaʻomia ai tulaga talafeagai ma faiga faʻataʻitaʻiga. E ui lava o nisi o faiga ua faia i totonu ma fafo, o loʻo i ai pea le tele o faʻaletonu. . O atunu'u i fafo talu ai nei na fa'atupuina le fa'aogaina o le plasma surface treatment technology e fa'amama ai le SiOx, AlOx ma isi mea fa'apipi'i oxide inorganic i luga o substrates e pei o PET ma BOPP e maua ai ata fa'apipi'i fa'atasi ai ma mea fa'alavelave maualuga. O le silicone-coated film e fai si mautu i le vevela ma e talafeagai mo le vevela maualuga kuka ma sterilization afifi meaai. O ata e fa'aleagaina, ata e mafai ona 'aina ma ata e so'ona vai, o mea uma ia e afifiina lanu meamata na atia'e e atunu'u o le lalolagi i tausaga talu ai nei. O su'esu'ega i le fa'aogaina o polymers fa'anatura macromolecular e pei o lipids, polotini ma suka e pei o ata afifiina ua fa'ateleina fo'i.

Afai ei ai ni au mea e manaʻomia mo le afifiina o meaʻai, e mafai ona e faʻafesoʻotaʻi matou. I le avea ai o se tagata gaosi mea e fa'apipi'i fetu'una'i mo le silia ma le 20 tausaga, matou te tu'uina atu au fofo sa'o afifiina e tusa ai ma au oloa mana'omia ma le paketi.
