Vashandi veAmerican Chemical Society vakagadzira eco-inoshamwaridzika packaging yekuchengetedza zvigadzirwa zvakasiyana. Inobva pafirimu ine casein, iyo inhengo yemukaka. Iyi puroteni inowanikwa semugumisiro wekuputika kwechinwiwa.
Material Features
Nekuona, zvinhu hazvina kusiyana neyakapararira polyethylene. Chinhu chikuru chepakeji nyowani ndechekuti inogona kudyiwa. Chigadzirwa chacho hachidi kubviswa kubva pakuputira kwekugadzirira, sezvo zvinhu zvinonyunguduka zvachose pakupisa kwakanyanya.
Vagadziri vacho vanoti iyo yekurongedza haina kukuvadza zvachose kumuviri wemunhu uye nharaunda. Nhasi, ruzhinji rwekurongedza chikafu chinogadzirwa kubva kune petroleum zvigadzirwa. Panguva imwecheteyo, nguva yekuparara kwezvinhu zvakadaro yakareba zvakanyanya. Somuenzaniso, polyethylene inogona kuora mukati memakore 100-200!
Mafirimu ane mapuroteni haatenderi mamorekuru eokisijeni kuti asvike kuchikafu, saka kurongedza kunochengetedza zvigadzirwa kubva mukuparara. Kutenda kune mafirimu aya, maererano nevagadziri vezvinhu zvitsva, zvichave zvichibvira kuderedza zvakanyanya kuwanda kwemarara epamba. Pamusoro pezvo, iyo yakasarudzika zvinhu inogona kuita kuti chikafu chinakidze zvirinani. Semuenzaniso, chikafu chinotapira chemangwanani chichawana kunaka kukuru kubva mufirimu. Imwe bhenefiti yemapakeji akadaro kumhanya kwekubika. Semuenzaniso, muto weupfu unogona kukandwa mumvura inopisa pamwe chete nebhegi.
Iyo budiriro yakatanga kuratidzwa pa252nd ACS kuratidzwa. Zvinotarisirwa kuti zvinyorwa zvichawana kushandiswa mune akati wandei maindasitiri munguva pfupi iri kutevera. Kuti uite, zvinodikanwa kuti tekinoroji yekugadzira mapakeji akadaro ishande mune zvehupfumi. Nekudaro, kutanga, izvo zvinyorwa zvinofanirwa kupasa ongororo yakasimba neUnited States Food and Drug Administration. Vanoongorora vanofanira kusimbisa kuchengetedzwa kwekushandiswa kwezvinhu zvekudya.
Zvimwe zvinopihwa
Masayendisiti anocherekedza kuti iyi haisi iyo yekutanga pfungwa yekugadzira inodyiwa yekurongedza. Nekudaro, iyo tekinoroji yekugadzirwa kwezvinhu zvakadaro parizvino haina kukwana. Saka, pakanga paine kuyedza kugadzira chikafu chekurongedza kubva kune starch. Zvisinei, zvinhu zvakadaro zvine porous, izvo zvinotungamirira kukupinda kweokisijeni mumakomba maduku. Somugumisiro, zvokudya zvinochengetwa kwenguva pfupi bedzi. Protein yemukaka haina pores, iyo inobvumira kuchengetedza kwenguva refu.
