Ngā Pūrongo - Te Whakamahinga o te Konutea Waikawa Noa hei Ārai i te Mate Korere o ngā Poaka

Ahau.

Waikura konutea, e mōhiotia whānuitia ana ko te konutea mā, he mea amphoterickonutea waikurakāore e wairewa i te wai engari ka wairewa i roto i te waikawa me te kawakore kaha. Ko tōna tauira matū ko ZnO, ko te taumaha ngota ko 81.37, ko te tau CAS ko 1314-13-2, ko te ira rewa ko 1975℃ (pirau), ko te ira kohua ko 2360℃, ā, kāore e wairewa i roto i te wai. E whakamahia whānuitia ana i roto i ngā mara neke atu i te 20 pēnei i te kirihou, ngā hua silicate, te rapa hangai, ngā hinu whakahinuhinu, ngā peita me ngā paninga, ngā hinu kakara, ngā piri, te kai, ngā pākahiko, ngā aukati mura,me ētahi atu

III. Ngā wero o te mate korere i roto i ngā poaka kua whakamutua te kai me te uara haumanu okonutea waikura

He mea nui te whakawhāiti i te kai ū i roto i te oranga o te poaka. Ko ngā raruraru pēnei i te ngoikore o te mahi ārai whekau, te korenga o te whakaputanga o ngā whākōkī nakunaku, me te kore taurite o ngā tipu ka arahi pea ki te mate korere i muri i te whakawhāiti (PWD), e tino whakararu ana i te tipu me ngā painga whakaputa uri o ngā poaka. Mai i te mea noakonutea waikurai kitea he pānga nui ki te ārai i te mate korere i ngā tau 1980, kua noho hei "paerewa koura" mō te umanga kararehe o te ao ki te whakatau i te hunga mate pāwera. Kua whakaatuhia e ngā rangahau ko te tāpiri i te 2500-3000 mg/kgkonutea waikuraka taea te whakaiti i te auau o te mate korere mā te 40%-60%, me te whakapiki i te pikinga taumaha o ia rā mā te 10%-15%. Ko tōna uara matua ko te tere o te whakatau i te taiao puku mā roto i ngā tikanga maha, hei whakarato i te tiaki whakawhiti nui mō ngā poaka iti.

IV.Te tikanga mahi akonutea waikuraārai i te mate korere

1)Te whakapakari i te ārai tinana o te puku

Waikura konuteaKa whakaoho i te tipu haere o ngā pūtau epithelial o te puku, ka whakanui ake i te ōwehenga o te teitei o te villus puku ki te hohonutanga o te crypt, ka whakapai ake i te horahanga o te mata mō te mimiti matūkai, ā, i te wā kotahi ka whakanui ake i te whakaaturanga o ngā pūmua hononga piri (Occludin, ZO-1), ka whakaiti i te urunga o te mucosal o te puku, ā, ka aukati i te whakaekenga mai o ngā pathogens. Ka tiaki i te mahi ārai mucosal o te puku, ka whakapai ake i te kaha patu huakita o ngā poaka iti, ā, ka whakaiti i te mate korere.

2)Te whakahaere i te taurite o ngā moroiti puku

Waikura konuteaka whakaputa i ngā rauropi kore utu hauwai peroxide i roto i te puku, he mea nui tēnei i roto i te mahi patu huakita okonutea waikuraTe horopeta nuikonutea waikuraKa aukati tika i te tipu haere o ngā huakita mate pēnei i a Escherichia coli me Salmonella mā te tuku i ngā momo hāora tauhohe (ROS), me te whakatairanga anō hoki i te noho o ngā huakita whai hua pēnei i a Lactobacillus.

3) Ka whakatairanga te nui o te konutea i te tipu o ngā poaka

Ka heke te ngāwari o te nakunaku o te whāngai i te 30% i te ahotea o te whakamutu i te kai, ā, ka heke haere te ngāwari o te nakunaku o ngā matūkai i roto i ngā poaka kua whakamutua te kai ina mate puku rātou. Kua whakaatuhia e ngā rangahautērāte tāpiri i ngā horopeta teitei okonutea waikuraka taea e te kai te whakanui ake i te taumata o te konutea i roto i te toto, te whakahaere anō i te tukunga o ngā peptides puku roro me ngā homoni hiakai, mewhakaohokia ngā poaka ki te kai. I taua wā anō, te pikinga o te nui o te konutea i roto i te totokēnete whakatairanga whai hua i te hanganga me te whakahohenga o ngā whākōkī nakunaku, whakapai ake i te nakunaku o ngā matūkai, mewhakanui ake i te taumaha o ngā poaka i ia rā.

IV. Mahere Whakamahinga Pūtaiao me ngā Whakatūpato

1. Te horopeta tika me te huringa whakamahinga

Ahakoa kua whakaritea he nui te konutea (1600-2500 mg/kg)konutea waikura) ka taea anake te whakamahi i te whāngai i roto i te"ngā wiki tuatahi e rua i muri i te whakatō", he maha ngā pāmu poaka e whakaroa ana i te whakamahinga o te whāngai konutea nui mō te 2-8 wiki. I tēnei wā, ka pāngia ētahi pāmu poaka e te"ngā pānga taha o te konutea nui", e kitea whānuitia ana he makawe matotoru, he roa, me te kiri mangu.

2. Kōwhirikonutea waikurame te pumau teitei hei whakapai ake i te pānga o te hua

Te wāteatanga koiora okonutea waikurahe nui ake te nui o te wai i puta mai i te tukanga mākū i tērā okonutea waikurai hangaia e te tukanga tika. Nō reira, i te wā e whiriwhiri anakonutea waikurangā hua, me whai whakaaro anō hoki ki te tukanga whakaputa.

5. Ngā Auahatanga o te Ahumahi me te Tirohanga Hangarau Rerekē

Ahakoa kua whakawhāitihia e te EU te nui o te konutea i tāpirihia ki te 150 mg/kg, e whakaatu ana ngā mahi ā-rohe kei te raru tonu te whakakapinga katoa i te konutea nui. Ko ngā huarahi kē atu o nāianei pērā i te nanokonutea waikura(300 mg/kg) me te konutea konutea taketake (1200 mg/kg) ka taea te whakaiti i te horopeta, engari he nui te utu, kāore i te rawaka te pumau o te tukanga, ā, me manatoko tonu te haumaru mō te wā roa. Nō reira,noakonutea waikurakoinei tonu te kōwhiringa pai rawa atu mā ngā pāmu iti me te rahi-waenga hei whakataurite i te utu me te pānga.
