Is aluminium foil yeiyo mishonga yekushandisa inokuvadza kune hutano hwedu?

Aluminium foil ikozvino yave zvatinoda zuva nezuva, uye iwe unogona kuona aluminium foil zvinhu zvakanyanya mumakicheni kana zvitoro zvemishonga. Vamwe vanhu vangashamisika, haisi aluminium foil metal? Zvichakuvadza hutano hwedu here? Nhasi, Huawei Aluminium ichapindura kusahadzika kwako mune izvi.

Kutanga kwazvose, ndezvechokwadi kuti aluminium foil haizokuvadzi miviri yedu. Kusanganisira iyo foil yemishonga, enda kufoil, uye pharma foil iyo yatinowanzoona mafuta emushonga kurongedza uye nezvimwe.

Zvisinei, sekuchengetedza kwezuva nezuva, yakasimba asidhi zvigadzirwa kana zvikafu zvine munyu wakawanda hazvifanirwe kuchengetwa mualuminium foil. Acid kana munyu-semuenzaniso kubva maapuro akachekwa, pickled magaka, cheke, kana soseji nyama-inogona kuburitsa aluminium ions kubva pafoiri, iyo inogona kutamira kune chikafu. Mugadziri akanyatsoratidza ichi chimiro pane chiputiriso. Chinangwa cheizvi ndechekuona kuti muganhu we 5 mg pakirogiramu yechikafu chakagadzwa neEuropean Council senzira yekudzivirira haina kupfuudzwa.

“Kana iwe ukatevera mimwe mitemo, zvakachengeteka zvachose kushandisa aluminium foil sechinhu chekurongedza.” -Dr. Ulrich Nehring.

Nzvimbo yemashiripiti yealuminium foil packaging

Kushandiswa kwealuminium foil chinhu chakakosha mumafekitari emishonga: inopa dziviriro inoshanda pachiedza, oksijeni, mwando uye mabhakitiriya. Nekuda kwehunhu hwayo, aluminium foil inowedzera hupenyu hwesherufu yemishonga, nokudaro zvichiita kuti vanhu vasatambisa mishonga. Neichi chikonzero, aluminium foil inowanzo shandiswawo sechimwe chezvinhu zvakawanda mucomposite packaging system, semuyenzaniso, kubva pazvinhu zvinozivikanwa zvinoshandiswa kurongedza UHT mukaka. Here, kukora kwealuminium foil kunogona kuva chete 0.006 mm, nemamwe manzwi, yakaonda kupfuura bvudzi romunhu.

Zvisinei, maererano netsvakurudzo yesayenzi yazvino, kudyiwa kwealuminium hakukonzere njodzi dzehutano kune vakajairwa vane hutano vatengi: Maererano neEuropean Food Safety Agency (EFSA), kubva pamaonero ehupenyu, zvakachengeteka kushandisa milligram imwe yealuminium pakirogiramu yehuremu hwemuviri. Kune vanhu vanoyera 70 kg, muganhu wealuminium ndeye 70 mg pavhiki. Munhu ane itsvo dzine utano anokurumidza kubvisa 99.9% yealuminium kuburikidza neitsvo.

Uyezve, maererano nenzvero yesayenzi yemisi ichangobva kupfuura iyi, iyo WHO Joint Nyanzvi Komiti yeZvokudya Zvinowedzera (JECFA) yakawedzera iyo inoshivirira yekunyura muganho wealuminium kusvika 2 mg aluminium pakirogiramu yehuremu hwemuviri, izvo zvinoreva kuti isu tinogona kudzivisa zvachose kunetseka pamusoro pekukanganisa kwealuminium foil zvigadzirwa pahutano hwedu. Chii chakaipa mhedzisiro.
