I tēnei wā, ko te nuinga o ngā matūngā mea tiakiKo ngā mea e whakamahia ana i roto i tā mātou mākete ko te waikawa benzoic me tōna tote konutai, te waikawa sorbic me tōna tote pāhare pākawa, te waikawa propionic me tōna tote, ngā esters waikawa p-hydroxybenzoic (nipagin ester), te waikawa dehydroacetic me tōna tote konutai, te konutai lactate, te waikawa fumaric, me ētahi atu.
1. Te waikawa benzoic me tōna tote konutai
Ko te waikawa benzoic me tōna tote konutai tētahi o ngā mea e whakamahia whānuitia anangā mea tiakiI roto i te umanga tukatuka kai o Haina, e whakamahia ana mō te tiaki i ngā kai wai pērā i ngā inu (hei tauira, ngā inu ngohengohe, ngā wai hua, te ranu soya, ngā kai kēne, te waina, me ētahi atu). He waikawa lipophilic te waikawa benzoic, ā, ka ngāwari te uru atu mā roto i te kiriuhi pūtau ka tomo ki te tinana pūtau, ka whakararu i te urunga o te kiriuhi pūtau o ngā moroiti me te aukati i te mimiti o ngā waikawa amino e te kiriuhi pūtau. Ko te ngota waikawa benzoic e tomo ana ki te tinana pūtau, ka whakakoi i te rauemi kawakore i roto i te pūtau, ā, ka taea te aukati i te mahi a te pūnaha whākōkī manawa pūtau, ā, he mahi nui tana ki te aukati i te tauhohenga whakapūpū acetyl coenzyme A, kia whai pānga tiaki ai ki te kai.
2 Te waikawa sorbic me tōna tote pāhare pākawa
Ko te waikawa sorbic (potassium sorbate) te mea tiaki e whakamahia nuitia ana, ā, e whakamahia ana i te nuinga o ngā whenua. Ko te waikawa sorbic he waikawa ngako kore-kū, ko tana tikanga aukati ko te whakamahi i tana ake hononga takirua me ngā pūtau moroiti i roto i te whākōkī o te rōpū sulfhydryl kua honoa hei hanga i tētahi hononga honohono, kia ngaro ai te mahi, kia whakangaromia ai te pūnaha whākōkī. Hei tāpiri, ka taea hoki e te waikawa sorbic te whakararuraru i te mahi whakawhiti, pērā i te whakawhiti hāora e te cytochrome C, me te mahi o te whakawhiti pūngao kiriuhi pūtau, te aukati i te tipu o ngā moroiti, kia tutuki ai te kaupapa o te waikura.
3 Te waikawa propionic me tōna tote
He wai hinuhinu kore tae te waikawa propionic, he waikawa-mono. He mea ārai i te hanganga o te β-alanine i roto i ngā huakita me te pānga patu huakita. Ko ngā tote waikawa propionic he konutai propionate me te konupūmā propionate te nuinga, he rite tonu te tikanga tiaki, ka hurihia hei waikawa propionic i roto i te tinana, ka taea e ngā ngota waikawa propionic monomeric te hanga i te pēhanga osmotic teitei i waho o ngā pūtau pokepokea ai, kia maroke ai te pūtau pokepokea ai, kia ngaro ai te whakaputa uri, ā, ka taea hoki te uru ki roto i te pakitara pūtau pokepokea ai, kia aukati ai i te mahi ā-roto.
4 paraben ester (nipagin ester)
Ko ngā paraben esters ko te methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, me ētahi atu. Ko te tikanga aukati o ngā p-hydroxybenzoic acid esters ko: ka aukatihia te pūnaha manawa o te pūtau moroiti me te mahi a te pūnaha whākōkī whakawhiti irahiko, ā, ka taea te whakangaro i te hanganga o te kiriuhi pūtau moroiti, kia rite ai ki te mahi hei paturopi.
5 Te waikawa dehydroacetic me tōna tote konutai
Ko te waikawa dehydroacetic, ko te tātai ngota C8H8O4 me tōna tote konutai he paura tioata mā, he kōwhai mārama rānei, he kaha ki te patu huakita, he kaha ki te patu huakita i te harore me te rewena. He matū tiaki waikawa, ā, kāore e tino whai hua mō ngā kai koretake. He pumau ki te mārama me te wera, ka pakaru ki te waikawa acetic i roto i te wai, ā, kāore e paitini ki te tinana tangata. He matū tiaki whānui, ā, e whakamahia whānuitia ana mō te tiaki mīti, ika, huawhenua, hua rākau, inu, keke, me ētahi atu.
6 Te konutai lactate
He wai mārama, kāore he tae, he kōwhai paku rānei, kāore he kakara, he tote paku, he kawa paku, ka taea te whakaranu ki te wai, te etanoru, te kareihana. Ko te kukū whānui he 60%-80%, ā, ko te rohe whakamahinga mōrahi he 30g/KG mō te kukū 60%... He momo hou te konutai lactate o te matū tiaki me te matū tiaki, e whakamahia ana ki ngā hua mīti me ngā hua heihei, he kaha te aukati i ngā huakita kai mīti. E whakamahia ana ki ngā hua mīti tunutunu, te hāmi, te hōtiti, te heihei, te parera me ngā hua heihei me ngā hua ranu me te tote. Ko te tauira tohutoro mō te tiaki i te hou o ngā hua mīti: konutai lactate: 2%, konutai dehydroacetate 0.2%.
7 Dimethyl fumarate
He momo hou tēnei mō te ārai i te pokepokea aitiakiHe mea whakawhanake kaha i te kāinga me tāwāhi, ka taea te aukati i te neke atu i te 30 momo pokepokea me te rewena, ā, kāore tōna mahi patu huakita e pāngia e te uara pH, engari he pai te whai huatanga me te whānuitanga o te whānuitanga, te haumaru teitei me te utu iti. He pai ake tana mahi patu huakita me te patu huakita whānui, me te kaha koiora kaha. He āhuatanga whakapūkara tōna nā te whakakorikori, nō reira he mahi takirua tana hei whakahoromata whakapā me te whakahoromata whakakorikori. He iti te paitini, ka tere te uru ki te tinana tangata ki ngā wāhanga noa o te pākia o te tangata e te waikawa fumaric, ā, he pai te tukurua o te tono.
