Uphando lwezenzululwazikwimveliso, umgangatho kunye nokusetyenziswa okunokubakho kweefilimu ezityiwayo/ezinokubola kwimveliso yokutya ziye zaqhutywa ngamaqela amaninzi ophando kwihlabathi jikelele kwaye kuye kwaxelwa kupapasho lophando.5-9.Amandla amakhulu okurhweba kunye nokusingqongileyo kwindawo yeefilimu ezityiwayo/ezonakaliswayo/ezalekayo zihlala zigxininiswa.5,10,11kunye noshicilelo oluninzi luye lwajongana nemiba enxulumene neempawu zomatshini, ukufuduka kwegesi, kunye nemiphumo yezinye izinto kwezi zakhiwo, ezifana nohlobo kunye nomxholo weplastiki, i-pH, ukufuma okuhambelanayo kunye nobushushu njl.6, 8, 10-15.
Nangona kunjalo,uphando kwiifilimu ezityiwayo/ezinokonakalakusekutsha kwaye uphando malunga nokusetyenziswa kwemizi-mveliso yeefilimu ezityiwayo/ezinokubola zifumene ingqwalasela ethe chatha kule minyaka yakutsha nje, nangona kunjalo, ukujongwa kusenomda.
Abaphandi kwiiQela lokuPakisha ukutya, iSebe lezoKutya kunye neSayensi yeZondlo, iKholeji yaseYunivesithi yaseCork, e-Ireland, iye yavelisa iifilimu ezininzi ezisebenzayo, ezisekelwe kwi-biopolymer, ezidliwayo / eziphilayo kwiminyaka embalwa edlulileyo.
Unyino lwepakethe enokutyiwa
Ngokubanzi, iifilimu ezityiwayo zinosetyenziso olulinganiselweyo ngenxa yeempawu ezisezantsi zomzimba.Umzekelo, iifilimu ezingatshatanga, ezisekwe kwi-lipid zineempawu ezintle zokuthintela ukufuma kodwa azinawo amandla omatshini23.Ngenxa yoko, iifilimu ezenziwe ngelaminated zenziwa ngokubambelela kwiifilimu ezimbini okanye ngaphezulu zebhayopolymer kunye.Nangona kunjalo, iifilimu ezilayitiweyo ziluncedo kwiifilimu ze-biopolymer enye, esekwe emulsion ngenxa yokuba nazo zineempawu zothintelo eziphuculweyo.Ukudalwa kwezakhiwo ze-laminated kunamandla okunqoba ezi ntsilelo ngobunjineli beefilimu ezidliwayo / ezihlanjululwayo kunye neengqimba ezininzi ezisebenzayo.
Iifilimu ezidliwayo kunye neenguboNgokusekwe kwiiproteni ezinyibilikayo emanzini zihlala zinyibilika ngokwazo ngokwazo kodwa zineoksijini ebalaseleyo, ilipid kunye neempawu zokuthintela incasa.Iiprotheyini zisebenza njengento edibeneyo, i-matrix yesakhiwo kwiinkqubo ezininzi ze-multicomponent, iifilimu ezivelisayo kunye neengubo ezinempahla emihle yomatshini.I-Lipids, kwelinye icala, zisebenza njengezithintelo ezilungileyo zokufuma, kodwa zinegesi embi, i-lipid kunye nezithintelo zencasa.Ngokudibanisa iiprotheni kunye ne-lipids kwi-emulsion okanye i-bilayer (i-membrane equkethe i-molecular layers ezimbini), iimpawu ezintle zombini zinokudibaniswa kunye nezinto ezingalunganga ziyancipha.
Kuphando olwenziwe yiIqela lokuPakisha ukutyae-UCC, iimpawu ngokubanzi zeefilim eziphuhliswayo ezityiwayo/ezinokonakala zezi zilandelayo:
- Ukutyeba kweefilimu ezenziweyo ezityiwayo/ezinokonakala ukusuka kwi-25μm ukuya kwi-140μm
- Iifilimu zinokucaca, zicace, kwaye ziguquguquke okanye zingabonakali ngokuxhomekeke kwizithako ezisetyenzisiweyo kunye nobuchule bokucubungula obusetyenzisiweyo.
- Iindidi ezithile zefilimu eziguga phantsi kweemeko ezilawulwayo zokusingqongileyo ziphucule iimpawu zomatshini kunye nezixhobo zokuthintela igesi
- Ukugcina iifilimu kwimeko ye-ambient (18-23 ° C, 40- 65 per cent RH) iminyaka emihlanu ayizange itshintshe kakhulu iimpawu zesakhiwo.
- Iifilimu ezenziwe ngezithako ezahlukahlukeneyo zinokuthi zenziwe lula kunye ne-laminated kunye
- Iifilimu ezenziweyo zinokubhalwa, ziprintwe okanye zitywinwe ngobushushu
- Iiyantlukwano ezincinci kwi-microstructure yefilimu (umzekelo ukwahlukana kwesigaba se-biopolymer) kuchaphazela iimpawu zefilimu
