Zikafika pakuyika zakudya ndi zotengera, chiphaso chamgulu lazakudya ndikofunikira kuti titsimikizire chitetezo ndi mtundu wazinthu zomwe timagwiritsa ntchito.Zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri pazakudya ndi silicone ndi pulasitiki, zonse zili ndi ziphaso zosiyanasiyana zomwe zimawapangitsa kukhala otetezeka kukhudzana ndi chakudya.M'nkhaniyi, tiwona ziphaso zosiyanasiyana za silicone ya chakudya ndi pulasitiki, kusiyana kwawo ndi ntchito.
Satifiketi ya silicone ya chakudya:
- Chitsimikizo cha LFGB: Chitsimikizochi ndi chofunikira ku European Union, chosonyeza kuti zida za silikoni zimakwaniritsa zofunikira pazakudya, malamulo aumoyo ndi chitetezo ndi miyezo.Zogulitsa za silicone zovomerezeka ndi LFGB ndizotetezeka kukhudzana mwachindunji ndi chakudya.Pali njira zingapo zoyesera za certification ya LFGB, kuphatikiza zinthu zomwe zimasamuka, zitsulo zolemera, kuyesa kununkhiza ndi kununkhira.
- Chitsimikizo cha FDA: FDA (Food and Drug Administration) ndi bungwe loyang'anira ku United States lomwe limatsimikizira chitetezo ndi mphamvu ya chakudya, mankhwala ndi zida zamankhwala.Zogulitsa za silikoni zovomerezedwa ndi FDA zimawonedwa ngati zotetezeka kuti zigwiritsidwe ntchito polumikizana ndi chakudya.Dongosolo la certification la FDA limawunika zida za silikoni pamapangidwe ake, mawonekedwe ake, ndi zinthu zina kuti zitsimikizire kuti ndizogwirizana ndi chakudya.
- Medical Grade Silicone Certification: Chitsimikizochi chikuwonetsa kuti zinthu za silikoni zimakumana ndi USP Class VI ndi miyezo ya ISO 10993 ya biocompatibility.Silicone ya kalasi yachipatala ndiyoyeneranso kugwiritsa ntchito chakudya chifukwa imagwirizana kwambiri ndi biocompatible komanso wosabala.Silicone ya kalasi yachipatala nthawi zambiri imagwiritsidwa ntchito pazaumoyo komansomankhwala mankhwalachoncho ayenera kutsatira mfundo zokhwimitsa chitetezo.
Chitsimikizo cha Pulasitiki Chakudya:
- PET ndi HDPE Certification: Polyethylene terephthalate (PET) ndi high-density polyethylene (HDPE) ndi mitundu iwiri yodziwika bwino ya pulasitiki yomwe imagwiritsidwa ntchito popakira zakudya ndi zotengera.Zida zonsezi ndi zovomerezeka ndi FDA kuti zigwirizane ndi chakudya ndipo zimawonedwa ngati zotetezeka kuti zigwiritsidwe ntchito m'zakudya ndi zakumwa.
- PP, PVC, Polystyrene, Polyethylene, Polycarbonate ndi Nayiloni Zovomerezeka: Mapulasitikiwa alinso ndi chilolezo cha FDA chokhudzana ndi chakudya.Komabe, ali ndi magawo osiyanasiyana achitetezo komanso ogwirizana ndi kugwiritsa ntchito chakudya.Mwachitsanzo, polystyrene sichivomerezeka pazakudya zotentha kapena zamadzimadzi chifukwa cha kutentha kwake kochepa, pamene polyethylene ndi yoyenera kuzizira komanso kutentha.
- Chitsimikizo cha LFGB: Zofanana ndi silicone, mapulasitiki a chakudya amathanso kukhala ndi satifiketi ya LFGB kuti igwiritsidwe ntchito ku EU.Mapulasitiki ovomerezeka a LFGB adayesedwa ndipo adapezeka kuti ndi otetezeka kuti agwiritsidwe ntchito polumikizana ndi chakudya.
Kusiyana kwakukulu pakati pa certifications ndi miyezo yawo yoyesera ndi zofunikira.Mwachitsanzo, certification ya FDA ya silikoni imawunika momwe zinthu zimakhudzira chakudya komanso kuopsa kwa kusamuka kwa mankhwala, pomwe chiphaso cha silikoni ya kalasi yachipatala chimayang'ana kwambiri pa biocompatibility ndi kutsekereza.Momwemonso, chiphaso cha mapulasitiki chimakhala ndi zofunikira zosiyanasiyana kutengera kuchuluka kwa chitetezo komanso kugwirizana ndi kugwiritsa ntchito chakudya.
Pankhani ya kagwiritsidwe ntchito, ziphasozi zitha kuthandiza ogula kusankha mwanzeru pazinthu zomwe amagwiritsa ntchito popakira zakudya ndi zotengera.Mwachitsanzo, PET ndi HDPE amagwiritsidwa ntchito kwambiri m'mabotolo amadzi, pamene polycarbonate imagwiritsidwa ntchito m'mabotolo a ana ndi makapu chifukwa cha kulimba ndi mphamvu.Ma silicones ovomerezeka a LFGB ndi mapulasitiki ndi oyenera kugwiritsa ntchito zakudya zosiyanasiyana kuphatikiza zisankho zophika buledi, zophikira ndi zosungiramo zakudya.
Ponseponse, kutsimikizira kwa ma silicones ndi mapulasitiki amtundu wa chakudya kumachita gawo lofunikira pakuwonetsetsa chitetezo ndi mtundu wazinthu zomwe timagwiritsa ntchito polumikizana ndi chakudya.Pomvetsetsa kusiyana pakati pa ziphasozi, ogula amatha kusankha mwanzeru zinthu zomwe amagwiritsa ntchito ndikukhala ndi chidaliro kuti iwo ndi mabanja awo ali otetezeka.
