Mushure mekudya zvishoma kwesmoothie yangu yestrawberry-banana, chandakangogona kuravira kwaive kunyangadza, kuravira kwepepa kwesadza.
Haina kungopeta chete, asiwo yakapetwa pachayo, ichidzivirira chinwiwa kuti chirege kuyerera chichikwira.Ndakarasa sadza ndokunhonga hutsva, rimwe sadza rebepa, nekuti ndizvo chete zvaifanira kupiwa muresitorendi.Sadza harina kubatawo chimiro charo, ndakabva ndapedza kunwa zvangu ndisina kana sadza.
Pepa rinokurumidza kutora zvinwiwa, uye nekukurumidza rinorasikirwa nechimiro chayo uye kusimba.Tsvagiridzo yakaitwa neKorea Research Institute of Chemical Technology (KRICT) yakaratidza kuti mashanga epepa akanyorova, ane huremu hweavhareji yemagiramu makumi maviri neshanu, anokotama mushure memasekondi makumi matanhatu.Saizvozvo, mashanga akagadzirwa nezvinhu zvataurwa aratidza kuva asina kuvimbika, sezvo achiwanzova asingashandiswi.
Mashanga emapepa anokunda nekuti mashanga akavharwa anotsemuka nekuchimbidza kupfuura mashanga epurasitiki echinyakare uye anoenderana nenharaunda, asi dambudziko remashanga akanyorova richiripo.“
Kurwisa izvi, mamwe mabrand anogadzira mashanga akavharidzirwa (zvakafanana nemabhegi epurasitiki neglue) izvo zvinodzivirira bepa kuti risasangana nehunyoro nekukurumidza.
Zvisinei, mashanga aya anotora nguva yakareba kuora, kunyanya munyanza.Izvi zvinopesana nechinangwa chekubvisa mashanga epurasitiki, ayo anotora makore anosvika 300 kuti awore kana zvichienzaniswa nemashanga anogadzirwa nebepa chete.
Zvakadaro, mashanga emapepa ane hushamwari hwezvakatipoteredza uye mashanga akavharidzirwa anoora nekukurumidza kupfuura mashanga epurasitiki echinyakare, asi pachine dambudziko remwando mumasowe.Izvi ndizvo zvaiyedzwa neKRICT kugadzirisa uye vakazviita.
Chikwata chakawana chifukidziro che cellulose nanocrystals (PBS/BS-CNC) iyo yakaparara zvachose mukati memazuva 120 uye yakachengetedza chimiro chayo, ichibata magiramu makumi mashanu kunyangwe mushure memasekondi makumi matanhatu.Nekune rimwe divi, kuti mashanga aya anopera zvakadii haanyatso kujeka, sezvo rudzi rwemashanga avakafananidzwa nawo haasati atsanangurirwa uye anogona kunge ari emhando yakaderera kumashanga akajairwa pamusika, pamwe nekusimba kwese. urefu.mashanga matsva haana kuratidzwa.Zvisinei, aya mashanga matsva akabvumikisa kuva akasimba.
Kunyangwe mashanga aya akavandudzwa asvika pamusika mukuru, haazogutsi.Mashanga emapepa anopetwa nekufamba kwenguva haakwanise kuenzaniswa nemashanga epurasitiki maererano nekuchengetwa kwechimiro, zvichireva kuti makambani acharamba achitengesa sadza repurasitiki uye vanhu voramba vachiatenga.
Nekudaro, isu tinogona kuramba tichikurudzira kugadzirwa kwemashanga epurasitiki akasimba.Izvi zvinosanganisira mashanga matete, zvose mukukora uye muupamhi.Izvi zvinoreva kushandisa mapurasitiki mashoma, zvinoreva kuti kwete chete ivo vanoputsa nekukurumidza, asi ivo vachashandisawo zvinhu zvishoma: yakanaka kune maindasitiri anoagadzira.
Pamusoro pezvo, vanhu vanofanira kuedza kushandisa mashanga anogona kushandiswa zvakare semashanga esimbi kana mashanga eshenjere kuderedza marara.Hongu, kudiwa kwemashanga anoraswa kuchaenderera mberi, zvichireva kuti masanga akaita seKRICT neaya anoshandisa mapurasitiki mashoma anodiwa seimwe nzira yesadza remapepa.
Kazhinji, mashanga emapepa anenge asingachashandi.Idzo hadzisi mhinduro kuhuwandu hukuru hwemarara asina-biodegradable anogadzirwa nemashanga.
Mhinduro dzechokwadi dzinofanirwa kuwanikwa, nekuti njodzi kune hutano hwepasi yakatonyanya kukura, uye iyi ndiyo yekupedzisira masanga.
