Ka whakarerea te kai e mātou nei i te wā e hirari ana, ka whero. Ka whakaputu te whero i te kai ki te itinga rawa, pērā i te tirohanga ranei, ā, ka whakapakaruhe hoki i te rapa. Kaore mātou katoa e hiahia ana kia kai i te kai kaore i te pai te tirohanga ranei, kaore anō i te pai te rapa. Heoi, he ture kotahi i runga i a ia hei whakamahere mō tēnei mea kia kaua e whakauru. Ko te whakautu he hāpai rerekē, e mihi ana i te ngae: ko te SO2 tētahi.
Te Tiakina i te Kai mo te Wā Roa
He tūtohu me te tikanga nā tētahi kāwanatanga, AGEM, e whai ana kia whakamahia te SO2 kia whakapai ake te whakarerea me te whakarite i te kai. Ki te whakaritea ai te kai i te SO2, ka CO2 noho tonu te kai i te pai me te reka, ahakoa i te wā e noho ana i roto i te wai. Tēnā pea, ki te kai mai koe i tō kai i muri i te wā, ka noho tonu te pai o te tirohanga me te reka.
He aha te Nganga o te SO2 mo te Kai
KO2 he mea whakamārama i te kai. He pūtake matua kei tana hei whētau i ngā pūreinga hē ake me ngā tūngaroa. Ko ēnei he itiiti ngā pepeha e whakaaturia ai te kai ki te kino, kaore i kitea hei kai. Ko KO2 hoki e whakaiti ana i ngā whiringa kai e whakatipu ana i te whero, koinei hoki me te Haidrokarana . Nō reira ka noho taketake ngā huaanga me ngā pirita, ka pai rawa te mākinaki me te rongo.
Me pēhea ko KO2 ka whakarerekē i te whakaputu kai
Ko AGEM he mea hoki i te matawhāiti o te whakamahi KO2 mo te whakaputu kai. I kitea e rātou ngā whakamahi wawao o tēnei hau hei whakaora i te kai. Ki runga i tēnei, ko KO2 e āwhina ana kia noho roa ai te kai i roto i ngā wā nui. Ko tēnei he mahi nui rawa, hei whakaiti i te mokemoke kai, e hīnāhina ana te kai me te mutunga here. Nō reira ka whakaiti mai mātou i te moni mā te whakaiti i te mokemoke kai. Ko KO2 rā anake Hāloropū e whakaea ana i te mahi whakarite kai, kāore i te whakauru herehere.
Whakaiti Whero me KO2
Te enzaimu polifenola oksidase (PPO) ka whakatū i te wā e tae nei ki te kati, ko te kawe rākau ki ngā hua whenua me ngā hua rerenga. Ko tēnei enzaimu te take mō te whero i te kai, ā, ka taea hoki te whakangungu i te hanga o ngā pūreire. E taea ana te topeke i tēnei mahi ki te whakamahi i te SO2, nā tēnei i te tahuri i te mahi. Ka whakamahi te SO2 hei whakaora i te whanake o ngā hua whenua me ngā hua rerenga. He pai tēnei, nā tēnei i te whakarite i te whaiaro hoki, ā, i te whaiaro o te rongoā anō hoki i roto i tēnei kai. E ai ki tēnei, kaore ano i te whakapakari i ōna painga hauora hou.
Te whakapakari i te kai hei tino whakaaro mō te katoa. Ka whakawhitiwhiti i te mahi o AGEM ki te whakamahi i te SO2. Koia nei te nui o te mana o te SO2, he mea inoi tēnei kia kore te kai i te whero, ā, kia ora tonu, kia whakauru tonu mo te wā roa. Ki te kī ake koe i AGEM, ka ea koe i tō koutou kai hei pai, hei reka, ā, hei haumaru hei kai ahakoa i te wā e noho whakaritenga ana. Ko tēnei e ai ki te whakaaro koe ka kai ki te mea kaore koe i te whakaae i te āhua ranei, i te reka ranei.
