Ukuze kukhiqizwe enye indlela evumelana ne-eco-friendly esikhundleni sokupakisha ukudla kwepulasitiki neziqukathi, usosayensi wase-Rutgers University usungule i-biodegradable plant-based coating engafuthwa ekudleni ukuze kuvikelwe kuma-pathogenic and spoilage microorganisms kanye nomonakalo wemikhumbi.#Fan indebe yephepha

Inqubo enwebekayo ingase yehlise umthelela omubi wemvelo wokupakishwa kokudla kwepulasitiki futhi ivikele impilo yabantu.

Philippe Democritu, umqondisi weCentre for Nanoscience and Advanced Materials Research, kanye neHenry Rutgers School of Public Health kanye noProfesa weNanoscience kanye ne-Environmental Bioengineering e-Institute of Environmental and Occupational Health Sciences.“Sabuye sazibuza, ‘Singakwazi yini ukuklama izinto ezipakishwayo ezinweba isikhathi sokuhlala eshalofini, ezinciphisa ukumoshwa kokudla, futhi zikhulise ukuphepha kokudla?’”

U-Demokritou wanezela: “Esikuphakamisayo ubuchwepheshe obunokwethenjelwa obusivumela ukuthi siguqule ama-biopolymers, angakhishwa emfucumfucwini yokudla njengengxenye yomnotho oyindilinga, abe imicu ehlakaniphile engagoqa ukudla ngokuqondile.Lena ingxenye entsha yesizukulwane sokupakisha ukudla "okuhlakaniphile" kanye "okuluhlaza".

Ucwaningo lwenziwe ngokubambisana nososayensi base-Harvard University futhi luxhaswe yi-Harvard-Nanyang Technological University/Singapore Sustainable Nanotechnology Initiative.#Wholesale Yibin paper cup fan

I-athikili yabo, eshicilelwe kujenali yesayensi 《Nature Foods》, ichaza ubuchwepheshe bokupakisha obunoveli obusebenzisa imicu ye-polysaccharide/biopolymer-based.Njengewebhu esakazwa umlingiswa we-Marvel Comics uSpider-Man, okokusebenza kwe-viscous kungaphothwa kusuka kudivayisi yokushisisa efana nesomisi sezinwele futhi "nciphe" phezu kokudla kwazo zonke izinhlobo nosayizi, okufana nokwatapheya noma i-brisket Steak.Impahla egoqwe ngokudla ewumphumela iqine ngokwanele ukuvikela imihuzuko futhi iqukethe ama-antibacterial agents ukulwa nokubola kanye namagciwane abangela izifo afana ne-E. coli ne-Listeria.

Iphepha locwaningo lichaza indlela ebizwa ngokuthi i-focused rotary jet spinning, inqubo yokukhiqiza ama-biopolymers, kanye nokuhlolwa kwenani okubonisa ukuthi ukumbozwa kwelula isikhathi seshalofu likakotapheya ngamaphesenti angama-50.Ngokwalolu cwaningo, ukumbozwa kungagezwa ngamanzi bese konakala emhlabathini zingakapheli izinsuku ezintathu.

Ukupakishwa okusha kuhlose ukubhekana nenkinga enkulu yemvelo: ukwanda kwemikhiqizo yepulasitiki esekwe kuphethiloli emifudlaneni yemfucuza.Imizamo yokunqanda ukusetshenziswa kwepulasitiki, njengomthetho ezifundazweni ezifana neNew Jersey ukuqeda umkhuba wokukhipha izikhwama zepulasitiki ezitolo zokudla, ingasiza, kusho uDemokritou.Kodwa bafuna ukwenza okwengeziwe.#APP inkomishi yephepha fan

“Angiphikisani nopulasitiki, ngimelene nopulasitiki osuselwe ku-petroleum esilokhu siwulahla laphaya ngoba incane ingxenye yawo engagaywa kabusha,” kusho uDemokritou.Kule minyaka engama-50 kuya kwengama-60 edlule, eminyakeni yepulasitiki, sibeke amathani ayizigidi eziyizinkulungwane eziyi-6 emfucumfucu yepulasitiki endaweni yethu.Lapho ziwohloka kancane kancane.Lezi zingcezu ezincane zingena emanzini esiwaphuzayo, ukudla esikudlayo nomoya esiwuphefumulayo.”

Ubufakazi obukhulayo obuvela ethimbeni locwaningo lika-Demokritou nabanye bukhomba emiphumeleni yezempilo engaba khona.

Leli phepha lichaza ukuthi i-fiber entsha egoqa ukudla ihlangana kanjani nezithako ze-antibacterial ezenzeka ngokwemvelo - amafutha e-thyme, i-citric acid ne-nisin.Abacwaningi abaseqenjini locwaningo lika-Demokritou bangahlela okokusebenza okuhlakaniphile ukuthi kusebenze njengenzwa, kusebenze futhi kucekele phansi izinhlobo zamagciwane ukuze kuqinisekiswe ukuthi ukudla kufika kungangcolisiwe.UDemokritou uthe lokhu kuzobhekana nokukhathazeka okukhulayo ngezifo ezitholakala ekudleni kunciphise nezigameko zokonakala kokudla.Umlandeli Wendebe Yamaphepha Ngesiphuzo Esishisayo

Ososayensi base-Harvard abenze lolu cwaningo bahlanganisa u-Kevin Kit Parker, u-Huibin Chang, u-Luke Macqueen, u-Michael Peters no-John Zimmerman be-Desease Biophysics Group e-John A.
