Izisebenzi ze-American Chemical Society zenze ukupakishwa kwe-eco-friendly ukuze kugcinwe imikhiqizo ehlukahlukene. Isekelwe kwifilimu ehlanganisa i-casein, eyingxenye yobisi. Le phrotheni itholakala ngenxa yokugoqa kwesiphuzo.
Izici Ezibalulekile
Ngokubukeka, izinto azifani neze ne-polyethylene esabalele. Isici esiyinhloko sephakheji entsha ukuthi ingadliwa. Umkhiqizo awudingi ukususwa emaphaketheni ukuze ulungiselelwe, njengoba impahla ihlakazeka ngokuphelele emazingeni okushisa aphezulu.
Abathuthukisi bathi ukupakishwa akunangozi ngokuphelele emzimbeni womuntu kanye nemvelo. Namuhla, iningi lokupakishwa kokudla lenziwa ngemikhiqizo ye-petroleum. Ngesikhathi esifanayo, isikhathi sokubola kwezinto ezinjalo side kakhulu. Isibonelo, i-polyethylene ingabola phakathi neminyaka eyi-100-200!
Amafilimu aqukethe amaprotheni awavumeli ama-molecule e-oksijini ukuthi afinyelele ukudla, ngakho-ke ukupakishwa kuzovikela ngokuthembekile imikhiqizo ekonakalisweni. Ngenxa yalawa mafilimu, ngokusho kwabadali bezinto ezintsha, kuzokwazi ukunciphisa kakhulu inani lemfucuza yasendlini. Ngaphezu kwalokho, izinto eziyingqayizivele zingenza ukudla kunambitheke kangcono. Isibonelo, okusanhlamvu okumnandi kwasekuseni kuzothola ukunambitheka okuhle kwefilimu. Enye inzuzo yamaphakheji anjalo ijubane lokupheka. Isibonelo, isobho esiyimpuphu singaphonswa emanzini abilayo kanye nesikhwama.
Ukuthuthukiswa kwaboniswa okokuqala embukisweni we-252nd ACS. Kulindeleke ukuthi impahla ithole ukusetshenziswa ezimbonini eziningi maduze nje. Ukuze kusetshenziswe, kuyadingeka ukuthi ubuchwepheshe bokukhiqiza amaphakheji anjalo busebenza ngokwezomnotho. Kodwa-ke, okokuqala nje, okubalulekile kufanele kudlule ukubuyekezwa okuqinile yi-United States Food and Drug Administration. Abahloli kumele baqinisekise ukuphepha kokusetshenziswa kwezinto zokudla.
Okunye okunikezwayo
Ososayensi bayaqaphela ukuthi lona akuwona umbono wokuqala wokudala amaphakheji adliwayo. Kodwa-ke, ubuchwepheshe bokukhiqiza izinto ezinjalo okwamanje abuphelele. Ngakho-ke, kube nomzamo wokudala ukupakishwa kokudla kusuka kusitashi. Kodwa-ke, into enjalo i-porous, okuholela ekungeneni komoya-mpilo emigodini encane. Ngenxa yalokho, ukudla kugcinwa isikhashana nje. Amaprotheni obisi awaqukethe ama-pores, okuvumela ukugcina isikhathi eside.
