Zomwe Muyenera Kudziwa Mukamagwiritsa Ntchito Zotengera Zakudya Zapulasitiki Zotayidwa?

Zotengera zakudya zapulasitiki zimakhala zotayidwa ndi pulasitiki, zomwe zimasungidwa kwanthawi yochepa -. Ndi zinthu zapakhomo zomwe zimagwiritsidwa ntchito posungira zipatso, zakudya, zokhwasula-khwasula, ndi zakudya zina. Ndi zabwino monga kukhala wopepuka komanso sachedwa kusweka, zotengera zapulasitiki izi zatchuka kwambiri. Koma kodi mukudziwa zomwe muyenera kusamala mukazigwiritsa ntchito?

 

● Kusamuka kwa Ma Chemical: Mankhwala a m’zotengera zakudya za pulasitiki amatha kusamukira m’zakudya, zomwe zingasokoneze kukoma kwa chakudyacho. Chodetsa nkhawa kwambiri ndi chakuti zinthu zapoizoni komanso zovulaza zimatha kuwononga chitetezo cha chakudya ndikuwononga thanzi la anthu.
● Nkhani Zaukhondo: Kusaukhondo kwa zotengera zapulasitiki, monga kuipitsidwa ndi tizilombo tosaoneka ndi maso, kungakhudze thanzi la munthu.

(1) Dziwani Zolemba Zazida:
Zotengera zakudya zimapangidwa kuchokera kuzinthu zosiyanasiyana zapulasitiki. Nthawi zambiri, pansi pa chidebecho pamakhala chizindikiro cha katatu, chokhala ndi nambala yochokera ku 1 - 7 mkati. Nambala iliyonse imayimira zinthu zapulasitiki. Mwachitsanzo, nambala 5 imayimira polypropylene (PP). Zinthuzi ndizotetezeka, zimatha kupirira kutentha kwambiri, ndipo nthawi zambiri zimagwiritsidwa ntchito popanga zakudya zomwe zimatha kutenthedwa mu microwave.

(2) Zofunikira Zanyengo Pazinthu Zosiyanasiyana
● Zipangizo za PP: Zotengera zakudya za pulasitiki zopangidwa ndi PP zimatha kupirira kutentha kwambiri ndipo ndizoyenera kusungiramo zakudya zotentha ndi mbale.
● PS Containers: PS - zotengera zakudya zapulasitiki ndizolimba koma zimatha kusweka. Amayamba kufewa pamene kutentha kufika madigiri 75 . Choncho, chakudya chiyenera kuziziritsidwa mpaka kutentha kwa chipinda chisanayambe kuikidwa m'matumba amenewa. Komabe, ali ndi kutentha kocheperako - ndipo ndi oyenera kusunga zakudya zamufiriji.

(3) Kugwirizana kwa Chakudya
Zakudya zokhala ndi mafuta ambiri komanso shuga sizoyenera kuikidwa m'matumba apulasitiki. Kuwira kwa mafuta ndi madigiri 300, omwe amatha kupitirira kutentha kwa - kukana kwa pulasitiki. Kuonjezera apo, mafuta, shuga, plasticizers, ndi zinthu zina ndi organic mankhwala. Malinga ndi mfundo ya "monga zimasungunuka ngati," iwo akhoza kuchita mankhwala ndi zotengera zakudya.

(4) Pewani Kugwiritsa Ntchitonso
Zotengera zakudya zapulasitiki zomwe zimatha kutayidwa zimapangidwa kuti zizigwiritsidwa ntchito kamodzi kokha -. Kuzigwiritsiranso ntchito kungapangitse kuti zotengerazo zithe kukalamba ndi kukalamba, zomwe zimawonjezera chiopsezo cha kutulutsidwa kwa zinthu zovulaza. Komanso, poyeretsa zotengerazo, zotsukira zimatha kukhala pamwamba pake, zomwe zimawononganso chakudyacho.Chemical Substance Leaching.

(5) Chemical Substance Leaching
Mukamagwiritsa ntchito zotengera za pulasitiki zotayidwa, dziwani zomwe zingachitike ndi mankhwala. Izi zikhoza kuchitika powotcha chakudya, kusunga zakudya zamafuta kapena acidic. Zikatere, pulasitiki imatha kutulutsa mankhwala m'zakudya, makamaka ikakumana ndi kutentha, mafuta, kapena asidi. Izi ndizovuta kwambiri pazotengera zakale kapena zowonongeka.

Kukhazikitsidwa mu 2014, likulu lathu lili m'chigawo cha Guangdong. Tili ndi malo opangira malo okwana 14,400 masikweya mita, okhala ndi mizere 15 yopanga. Takwanitsanso kupanga digito pafakitale yoyambirira kudzera mu dongosolo la MES, ndikutulutsa pamwezi kopitilira matani 2,000. Pokhala ndi zaka zopitilira 11, timatha kukupatsirani - zotengera zabwino kwambiri za pulasitiki.
