Kuti apange njira yothandiza zachilengedwe yosungiramo chakudya cha pulasitiki ndi zotengera, wasayansi waku Rutgers University wapanga zokutira zomwe zimatha kuthiridwa pazakudya kuti ziteteze ku tizilombo toyambitsa matenda komanso kuwonongeka komanso kuwonongeka kwa sitima.#Paper cup fan

Njira yowonjezereka ikhoza kuchepetsa kuwonongeka kwa chilengedwe cha zakudya zamapulasitiki ndikuteteza thanzi la anthu.

Philippe Democritu, mkulu wa Center for Nanoscience and Advanced Materials Research, ndi Henry Rutgers School of Public Health ndi Pulofesa wa Nanoscience ndi Environmental Bioengineering ku Institute of Environmental and Occupational Health Sciences.“Tinadzifunsanso kuti, ‘Kodi tingapange zinthu zoti ziwonjezere nthawi ya shelufu, kuchepetsa kuwononga chakudya, ndi kuonjezera chitetezo cha chakudya?’”

Demokritou anawonjezera kuti: "Zomwe tikuganiza ndi ukadaulo wowopsa womwe umatilola kutembenuza ma biopolymers, omwe amatha kuchotsedwa ku zinyalala zazakudya monga gawo lachuma chozungulira, kukhala ulusi wanzeru womwe ungathe kukulunga chakudya mwachindunji.Ichi ndi gawo latsopano la m'badwo wa "zanzeru" komanso "zobiriwira" zonyamula zakudya.

Nkhani yawo, yomwe idasindikizidwa mu nyuzipepala yasayansi 《Nature Foods》, ikufotokoza zaukadaulo wazolongedza wogwiritsa ntchito polysaccharide/biopolymer-based fibers.Monga ukonde wopangidwa ndi Marvel Comics character Spider-Man, viscous material ikhoza kupota kuchokera ku chipangizo chotenthetsera chofanana ndi chowumitsira tsitsi ndi "kuchepa" pazakudya zamitundu yonse ndi makulidwe, monga ma avocados kapena brisket Steak.Zomwe zimakutidwa ndi chakudya zimakhala zamphamvu zokwanira kuti ziteteze ku mikwingwirima ndipo zimakhala ndi antibacterial agents kuti azilimbana ndi kuwonongeka ndi tizilombo toyambitsa matenda monga E. coli ndi Listeria.

Pepala lofufuzirali likufotokoza njira yotchedwa focused rotary jet spinning, njira yopangira ma biopolymers, ndi kuwunika kwachulukidwe kosonyeza kuti zokutira zimakulitsa moyo wa alumali wa mapeyala ndi 50 peresenti.Malinga ndi kafukufukuyu, zokutirazo zimatha kutsukidwa ndi madzi ndikuwonongeka m'nthaka mkati mwa masiku atatu.

Kupaka kwatsopanoku kumafuna kuthana ndi vuto lalikulu la chilengedwe: kuchuluka kwa zinthu zapulasitiki zopangidwa ndi petroleum m'mitsinje yazinyalala.Kuyesetsa kuletsa kugwiritsa ntchito pulasitiki, monga malamulo m'maboma ngati New Jersey kuti athetse mchitidwe wopereka zikwama zogulira pulasitiki m'masitolo ogulitsa, zingathandize, adatero Demokritou.Koma iwo akufuna kuchita zambiri.# APP pepala kapu wokonda

"Sinditsutsana ndi mapulasitiki, ndikutsutsana ndi mapulasitiki opangidwa ndi petroleum omwe timapitirizabe kutaya chifukwa chakuti ndi ochepa okha omwe angathe kubwezeretsedwanso," adatero Demokritou.Pazaka 50 mpaka 60 zapitazi, m'zaka za pulasitiki, tayika matani 6 biliyoni a zinyalala zapulasitiki m'malo athu.Kumeneko amanyonyotsoka pang’onopang’ono.Tizidutswa ting’onoting’ono timeneti timalowa m’madzi amene timamwa, chakudya chimene timadya komanso mpweya umene timapuma.”

Umboni womwe ukukula kuchokera ku gulu lofufuza la Demokritou ndi ena amaloza zomwe zingachitike paumoyo.

Pepalali likufotokoza momwe ulusi watsopano womwe umakulunga chakudya umaphatikizana ndi zinthu zachilengedwe zomwe zimachitika mwachilengedwe - mafuta a thyme, citric acid ndi nisin.Ofufuza mu gulu lofufuza la Demokritou amatha kukonza zinthu zanzeru kuti zikhale ngati sensa, kuyambitsa ndi kuwononga mabakiteriya amtundu wa bakiteriya kuti awonetsetse kuti chakudya chikufika chosakhudzidwa.Demokritou adati izi zithetsa nkhawa zomwe zikuchulukirachulukira za matenda obwera chifukwa cha zakudya komanso kuchepetsa kuchuluka kwa kuwonongeka kwa chakudya.#Paper Cup Fan For Hot Chakumwa
