He wai kore tae, kore kakara, paku matotoru te propylene glycol, he matotoru ake te kakano i te wai. Kāore rawa he reka, ā, he tāpiringa kai i hangaia e te matū. Pērā i te etanoru, he matū waipiro.

Hei tāpiritanga, hei whakarewa rauropi, ka taea e ia te whakarewa i ētahi matū rauropi pai ake i te wai, ā, ka taea hoki te pupuri i te makuku. Nā ēnei āhuatanga matū motuhake, he whānuitia te whakamahinga i roto i ngā mea whakapaipai. I te nuinga o te wā ka taea te whakamahi i te propylene glycol hei whakamakuku, hei whakangawari, hei whakarewa, me ētahi atu, ā, he tino pai ngā pānga whakamakuku me te paninga. Ka taea te whakamahi i roto i te nuinga o ngā mea whakapaipai, inā koa te wai, te hinu kiri, te kirīmi, te kopare kanohi me ētahi atu hua.

Haunga te ao whakapaipai, he mea nui anō hoki i roto i te ao kai. E mōhio ana ia ki a tātou, engari kāore tātou e aro nui ana ki a ia. E ai ki te "GB 2760-2014 National Food Safety Standard – Food Additive Usage Standard", ko ngā mahi a te propylene glycol ko: te whakaū, te whakakōkī, te ārai-kōkī, te tango huka, te whakaemulsifier, te pupuri makuku, me te whakamātotoru.

Nō reira, he maha ngā wā ka whakamahia hei whakapūhui kai hei tāpiri atu ki te taro, te pata me ētahi atu hua. Hei tāpiri, he maha ngā wā ka whakamahia te propylene glycol i roto i ngā tukanga tukatuka me te tango pia hei whakarewa mō ngā matū kakara.

Hei tāpiri, mō ngā hoa e pai ana ki te tunu, he hua e whakamahia whānuitia ana te propylene glycol, ka taea te āwhina i ngā keke kia pai ake te reka me te kakara.

E ai ki ngā paerewa ā-motu, ko te kai haumaru o te propylene glycol e whai ana i ngā paerewa i whakatakotoria e te International Joint Expert Group on Food Additives, arā, kaua te kai o ia rā e neke ake i te 25 mg ia kirokaramu o te taumaha tinana.

Mō te pakeke e 70 kg te taumaha, kāore te nui o te kai e kainga ana i ia rā e neke atu i te 1.75 karamu. I tēnei wā, i roto i te mahi hanga kai pēkana pērā i te keke, ina whakamahia te propylene glycol hei tāpiri, ko te huarahi e whakamahia ana ko te kore e neke ake i te 3 karamu mō ia kirokaramu o te kai.

Ka taea te whakaae kia whakamahia te propylene glycol hei tāpiringa kai, ā, kua paahitia e ia ngā aromatawai haumaru tino pakari. I raro i ngā "whakaaturanga whakamahinga paerewa me ngā kai", kāore te "kainga mō te wā roa" e kino ki te hauora.
