Izvo zvinogumira zvepakeji inodyiwa
Kazhinji, mafirimu anodyika ane mashoma ekushandisa zvakanyanya nekuda kweakaderera maitiro emuviri.Semuyenzaniso, ega, lipid-akavakirwa mafirimu ane yakanaka hunyoro inodzivirira zvivakwa asi haana simba remuchina23.Nekuda kweizvozvo, mafirimu akaumbwa akaumbwa nekunamatira maviri kana anopfuura biopolymer mafirimu pamwechete.Nekudaro, mafirimu akaramirwa anobatsira kune imwe chete, emulsion-yakavakirwa biopolymer mafirimu nekuda kwekuve kwavo nekwakawedzera barriers zvivakwa.Kusikwa kwemalaminated zvimiro zvine mukana wekukunda kukanganisa uku neainjiniya anodyika / biodegradable mafirimu ane akawanda anoshanda layers.
Mafirimu anodyiwa uye machirazvichibva pamapuroteni anonyungudika nemvura anowanzo kunyungudika mumvura asi ane okisijeni, lipid uye flavour barrier properties.Mapuroteni anoita seakabatana, structural matrix mune multicomponent masisitimu, anoburitsa mafirimu uye machira ane yakanaka mechanical properties.Lipids, kune rumwe rutivi, inoita seyakanaka hunyoro zvipingamupinyi, asi iine gasi rakashata, lipid uye zvipingamupinyi zvinonhuhwirira.Nekubatanidza mapuroteni uye lipids mu emulsion kana bilayer (membrane inoumbwa nezvikamu zviviri zvema molecular), hunhu hwakanaka hwezvose zviri zviviri hunogona kubatanidzwa uye zvakaipa zvinoderedzwa.
Kubva muongororo yakaitwa neChikafu Packaging GroupkuUCC, maitiro akajairwa eakagadziridzwa anodyika / biodegradable mafirimu ndeaya anotevera:
- Hukobvu hwemafirimu anodyika/anodegradable akagadzirwa anobva pa25μm kusvika 140μm.
- Mafirimu anogona kuve akajeka, akajeka, uye anopenya kana opaque zvichienderana nemidziyo inoshandiswa uye maitiro ekugadzirisa anoshandiswa.
- Kuchembera chaiwo mhando dzemafirimu pasi pemamiriro ekunze anodzorwa akavandudza zvimiro zvemichina uye gasi barriers zvivakwa
- Kuchengeta mafirimu pamamiriro ekunze (18-23 ° C, 40- 65 muzana RH) kwemakore mashanu hakuna kuchinja zvakanyanya maitiro.
- Mafirimu akaumbwa kubva kwakasiyana-siyana zvinongedzo anogona kuve nyore kunyudzwa pamwechete
- Mafirimu akagadzirwa anogona kunyorwa, kudhindwa kana kuvharwa kupisa
- Misiyano midiki mune firimu microstructure (eg biopolymer phase separation) inokanganisa firimu zvinhu
