Ukuvelisa enye indlela eco-friendly ekupakishweni kokutya kweplastiki kunye nezikhongozeli, isazinzulu seYunivesithi yaseRutgers siphuhlise i-biodegradable plant-based coating enokuthi itshizwe ekutyeni ukukhusela kwi-pathogenic kunye ne-spoilage microorganisms kunye nomonakalo wokuhamba ngenqanawa.#Ifeni yekomityi yephepha

Inkqubo enobungozi inokunciphisa impembelelo embi yokusingqongileyo yokupakishwa kokutya kweplastiki kunye nokukhusela impilo yabantu.

UPhilippe Democritu, umlawuli weZiko leNanoscience kunye noPhando lweZizinto eziPhambili, kunye neSikolo sikaHenry Rutgers seMpilo kaRhulumente kunye noNjingalwazi weNanoscience kunye ne-Environmental Bioengineering kwiZiko lezeNdalo kunye neSayensi yezeMpilo.“Kwakhona sizibuze, ‘Ngaba singakwazi ukuyila into yokupakisha eyandisa ixesha leshelufu, icuthe ukumoshwa kokutya, ize yandise ukhuseleko lokutya?’”

UDemokritou wongeze wathi: “Into esiyicebisayo bubuchwephesha obunokwehla esivumela ukuba siguqule ii-biopolymers, ezinokukhutshwa kwinkunkuma yokutya njengenxalenye yoqoqosho olujikelezayo, zibe ziintsinga ezikrelekrele ezinokusonga ukutya ngokuthe ngqo.Le yinxalenye entsha yesizukulwana sokupakisha ukutya "okuhlakaniphile" kunye "nohlaza".

Uphando lwenziwe ngokubambisana noososayensi kwiYunivesithi yaseHarvard kwaye baxhaswa ngemali yiHarvard-Nanyang Technological University / Singapore Sustainable Nanotechnology Initiative.#Wholesale Yibin iphepha indebe fan

Inqaku labo, elipapashwe kwijenali yenzululwazi 《Ukutya kweNdalo》, ichaza iteknoloji yokupakisha inoveli kusetyenziswa iifiber zepolysaccharide/biopolymer-based.Njengewebhu ephoswe ngumlinganiswa weMarvel Comics Spider-Man, imathiriyeli ye-viscous inokusontwa kwisixhobo sokufudumeza esifana nesomisi seenwele kwaye "icuthe" ngokutya kwazo zonke iimilo kunye nobukhulu, okufana neeavokhado okanye i-brisket Steak.Isiphumo sokutya esisongelwe ukutya sinamandla ngokwaneleyo ukukhusela imivumbo kwaye sinee-antibacterial agents zokulwa nokonakala kunye ne-microbes ebangela izifo ezifana ne-E. coli kunye ne-Listeria.

Iphepha lophando lichaza ubuchule obubizwa ngokuba yi-focused rotary jet spinning, inkqubo yokuvelisa ii-biopolymers, kunye novavanyo lobungakanani obubonisa ukuba ukugquma kwandisa ubomi beshelufu yeeavokhado ngama-50 ekhulwini.Ngokophononongo, olu gquba lusenokuhlanjwa luphele ngamanzi luze luthobeke emhlabeni kwisithuba seentsuku ezintathu.

Ukupakishwa okutsha kujolise ekujonganeni nengxaki enkulu yokusingqongileyo: ukwanda kweemveliso zeplastiki ezisekelwe kwipetroleum kwimijelo yenkunkuma.Iinzame zokuthintela ukusetyenziswa kweplastiki, njengomthetho kumazwe anje ngeNew Jersey ukuphelisa umkhuba wokunikezela ngeengxowa zokuthenga zeplastiki kwiivenkile zokutya, kuya kunceda, utshilo uDemokritou.Kodwa bafuna ukwenza okungakumbi.#Ifeni yekomityi yephepha yeAPP

“Andichasene neeplastiki, ndichasene neeplastiki ezenziwe ngepetroleum esihlala sizilahla phaya kuba yipesenti encinci kuphela enokuthi isetyenziswe kwakhona,” utshilo uDemokritou.Kwiminyaka engama-50 ukuya kuma-60 edlulileyo, kwiminyaka yeplastiki, sibeke iitoni ezizibhiliyoni ezi-6 zenkunkuma yeplastiki kwindawo yethu.Apho ziya ziwohloka ngokuthe ngcembe.Ezi ngceba zincinane zingena kumanzi esiwaselayo, ukutya esikutyayo nomoya esiwuphefumlayo.”

Ubungqina obukhulayo obuvela kwiqela lophando likaDemokritou kunye nabanye bakhomba kwimiphumo enokubakho yezempilo.

Iphepha lichaza indlela i-fiber entsha edibanisa ukutya kunye nezithako ze-antibacterial ezenzeke ngokwemvelo - ioli ye-thyme, i-citric acid kunye ne-nisin.Abaphandi kwiqela le-Demokritou lophando banokucwangcisa izinto ezihlakaniphile ukuba zisebenze njengenzwa, zisebenze kwaye zitshabalalise iintlobo zebhaktheriya ukuqinisekisa ukuba ukutya kufika kungangcoliswanga.UDemokritou uthe oku kuza kujongana neenkxalabo ezikhulayo malunga nezigulo ezifumaneka kukutya kwaye kunciphise izehlo zokonakala kokutya.Umlandeli weNdebe yePhepha kwisiselo esishushu
