I roto i te ao hurihuri o ngā takai kai, te wāhi e tūtaki ai te haumaru, te roa o te wā e ora ai, me te pumau o ngā hua, kua puta ake ngā mea whakaū wai hei toa rongonui. Ko ēnei tāpiringa, he mea hanga tino tika mō ngā kiriata kai, he maha ngā mahi e whai pānga ana ki te hauora o te kaihoko me te whai huatanga o te ahumahi. Me ruku tātou ki ngā mahi matua e whā e kore ai e taea te whakaū wai i roto i ngā takai kai o ēnei rā.
Ātete Wera: Te Tiaki i ngā Kiriata mai i te WeraTe whakahekenga
Ko ngā kiriata kai, ahakoa he polyethylene (PE) he polypropylene rānei (PP), ka tukatukahia i te pāmahana teitei (hei tauira, te extrusion, te pupuhi pokepoke) tae atu ki te 230°C.Ngā mea whakaū waihei kaitiaki wera, hei aukati i ngā rauropi kore utu i puta i te wā e wera ana. I kitea i roto i tētahi rangahau a te Institute of Packaging Technologies, me te kore he mea whakau, i whakaatuhia e ngā tauira kiriata he 35% te hekenga o te kaha kume i muri i te 10 meneti i te 200°C. He rerekē,ngā kiriata me te whakaū wai kua arotauhiaNeke atu i te 90% o te kaha taketake i puritia e ngā whakatakotoranga, kia mau ai te pumau o te hanganga i ngā wā tunu kai pēnei i ngā paepae kai e taea te whakamahi i roto i te ngaruiti.
Te Whakaroa i te Ora o te Papa: Te Whakaiti i te Waikura me te Pakaru UV
Haunga te tukatuka, ka whawhai ngā wai whakaū ki ngā taumahatanga taiao i te wā e rokiroki ana, e kawe ana hoki. Ka taea e te hihi UV me te pānga o te hāora te whakaoho i te waikura whakaahua, ka kōwhai, ka pakarukaru hoki ngā kiriata. Hei tauira, i roto i tētahi whakamātautau whakatairite i runga i ngā takai maramara rīwai, i whakanuia e ngā kiriata me ngā tāpiringa wai whakaū UV te hou o te hua mā te 25%, e ai ki te uara peroxide. Ko ngā antioxidants e ahu mai ana i te waikawa ngako i roto i ngā wai whakaū ka hopu i te hāora, ko ngā mea mimiti UV pērā i te benzotriazoles ka tiaki i ngā kiriata mai i te kino o te hihi, ka tiaki i te ataahua o te takai me te uara kai o te kai.
Te āheinga tukatukaWhakapai ake: Te Arotau i te Rere Rewa me teTe ōritetanga
He wero kei mua i ngā kaihanga te whakatutuki i te matotoru o te kiriata me te mutunga o te mata. E ai ki ngā pūrongo ahumahi, ka whakaitihia e ngā whakaū wai te matotoru rewa tae atu ki te 18%, kia maeneene ake ai te whakaputanga. He mea tino nui tēnei whakapainga mō ngā raina whakaputa tere-rahi, ina taea e te rerekētanga matotoru o te 0.1 mm te arahi ki te para nui. Mā te whakatairanga i te whakapūmautanga rite tonu, ka whakaitihia e ngā whakaū ngā hapa pēnei i te rerekētanga o te mata o te kiri mango me te matotoru, ka hua ake he penapena utu me te whakapai ake i te hua.
Te Whakatutuki i ngā Ture: Te Whakapūmau i te Haumaru Kai me te KaihokoTe whakawhirinaki
Ko te haumaru o ngā kiriata kai-kai e whakawhirinaki ana ki te whakahaere i te hekenga o ngā tāpiringa. Me piri ngā wai whakapūmau ki ngā ture pakari, pērā i te US FDA 21 CFR 178.2010 me te EU Regulation (EC) No 10/2011. Hei tauira,ngā whakaū hanganga konupūmā-konutea, kua whakamanahia hei whakakapi kore-paitini ki ngā matū tuku iho e ahu mai ana i te mata, e tutuki ana i ngā paerewa rauemi whakapā kai o te ao. Nā te iti o te hekenga (≤0.1 ppm mō ngā konganuku taumaha) he mea tino pai mō ngā takai kai pēpi, he mea nui rawa ngā taha haumaru.
Te Whenua o te Ao: Ngā Auahatanga i roto i te Hangarau Whakapūmau
Kei te kite te umanga i tētahi nekehanga ki ngā wai whakapūmau e ahu mai ana i te koiora. Ko te hinu pīni soya kua whakapūmautia, i ahu mai i ngā rauemi whakahou, e 30% o te mākete whakapūmau e pai ana ki te taiao. Kei te tūhuratia hoki e ngā kairangahau ngā hanganga maha-mahi e whakakotahi ana i te whakapūmau me ngā āhuatanga hohe, pērā i ngā āheinga patu huakita. E oati ana ēnei whanaketanga ki te tautuhi anō i ngā paearu haumaru me te pumau o ngā takai kai.
Hei whakamutunga, ehara ngā wai whakaū i te mea he tāpiringa noa iho engari he wāhanga nui hei tiaki i te kounga o te kai, hei whakahaere i te whakaputanga, hei pupuri hoki i te tutuki i ngā ture. I te tipu haere o te hiahia o ngā kaihoko mō ngā takai haumaru ake, roa ake te mau, ka haere tonu te whanaketanga o ēnei matū maha-whakamahinga, ka akiaki i te auahatanga i roto i te pūnaha takai kai.
