Pamene chilimwe chifika, kutentha kwachititsa kuti anthu aziganizira kwambiri za kutsitsimuka ndi chitetezo cha chakudya.M'nyengo ino, chakudya chozizira chakhala chisankho chokondedwa kwa mabanja ambiri ndi ogula.Komabe, chinthu chofunika kwambiri kuti chakudya chozizira chikhale chapamwamba komanso chokoma kwambirikuyika chakudya chozizira. Kuyika chakudya chozizirasikuti amangofunika kukhala ndi mikhalidwe yopanda madzi komanso yotsimikizira chinyezi, komanso iyenera kukwaniritsa zofunikira zachitetezo cha chakudya ndikusunga.Kenako, tiwonanso mfundo zoyambira pakuyika chakudya chozizira komanso momwe tingasankhire zida zoyenera zoyikamo ndi njira kuti titsimikizire kutsitsimuka ndi chitetezo cha chakudya.
Kupaka zakudya zoziziraikuyenera kukwaniritsa mfundo izi:
1. Kusindikiza: Thekulongedza chakudya choziziraayenera kukhala ndi chisindikizo chabwino kuti mpweya wozizira usalowe mkati mwazoyikapo, komanso kuteteza kutuluka kwa chinyezi m'zakudya kapena kulowetsedwa kwa chinyezi chakunja.
2. Anti kuzizira ndi kusweka: Zida zoyikapo ziyenera kukhala ndi mphamvu zokwanira kuzizira ndi kusweka, kutha kupirira kuzizira kozizira pa kutentha kochepa, ndi kusunga kukhulupirika kwa phukusi.
3. Kutentha kwapang'onopang'ono: Zida zoyikapo ziyenera kukhala ndi kutentha kwapansi bwino ndikutha kupirira mapindikidwe ndi kuwonongeka kwa malo oundana, ndikusunga kukhazikika kwa phukusi.
4. Kuwonekera:Kupaka zakudya zoziziranthawi zambiri zimafunikira kuwonetsetsa bwino kuti ogula azitha kuyang'ana maonekedwe ndi mtundu wa chakudya.
5. Chitetezo cha Chakudya: Zida zoyikamo ziyenera kutsata miyezo yachitetezo cha chakudya, osatulutsa zinthu zovulaza, komanso kuti zisakhale ndi zotsatira zoyipa pakukula ndi kukoma kwa chakudya.
Zomwe zimagwiritsidwa ntchito nthawi zambirikuyika chakudya chozizira:
1. Polyethylene (PE): Polyethylene ndi pulasitiki yomwe imagwiritsidwa ntchito nthawi zambiri yokhala ndi kukana kutentha kochepa komanso kukana chinyezi, yoyenera kupanga zinthu zonyamula katundu monga matumba a chakudya chachisanu ndi mafilimu.
2. Polypropylene (PP): Polypropylene ndi chinthu china chodziwika bwino cha pulasitiki chokhala ndi kutentha kochepa kwambiri komanso kukana kwa mankhwala, komwe kuli koyenera kupanga zipangizo zopangira zinthu monga mazira okhudzana ndi Zakudya ndi matumba osindikizidwa.
3. Polyvinyl kolorayidi (PVC): PVC ndi yofewa komanso yosavuta kugwiritsira ntchito pulasitiki yokhala ndi kukana kwa kutentha kochepa komanso kukana chinyezi, yoyenera kupanga mabokosi oyikamo, mafilimu, ndi zina zotero za chakudya chachisanu.
4. Polyester (PET): poliyesitala ndi zinthu zapulasitiki zomwe zimakhala ndi thupi labwino kwambiri komanso kukana kutentha pang'ono, zoyenera kupanga zida zolumikizirana ndi Achisanu, mabotolo ndi zida zina zonyamula.
5. Chojambula cha aluminiyamu: Chojambula cha aluminiyamu chimakhala ndi mphamvu zabwino kwambiri zoteteza chinyezi komanso kutentha kwa kutentha, ndipo zimagwiritsidwa ntchito popanga matumba oyikamo, mabokosi, ndi zina zotero za chakudya chozizira.
Posankhakulongedza katundu kwa chakudya chozizira, m'pofunika kuganizira mozama zinthu monga mikhalidwe yazakudya, zofunika kutentha kosungirako, ndi malamulo ndi malamulo, ndikuwonetsetsa kuti zinthu zomwe zasankhidwa zikukwaniritsa miyezo yachitetezo cha chakudya.
