He maha ngā rongoā ārai-pokepoke me ngā rongoā ārai-kitakita kei te mākete, pērā i te waikawa benzoic me te konupūmā propionate. Me pēhea te whakamahi tika i ēnei hei whāngai kararehe? Kia tirohia e au ō rāua rerekētanga.

Konupūmā propionatemewaikawa benzoic E rua ngā tāpiringa whāngai e whakamahia whānuitia ana, e whakamahia ana mō te tiaki kai, te ārai-haeka me te ārai huakita hei whakaroa i te roa o te oranga o te whāngai me te whakarite i te hauora o ngā kararehe.

Konupūmā Propionatei roto i ngā Taupānga Whāngai

Ngā Mahi

• Te Ārai i te Haehae me te Rewena: Ka ārai pai i te tipu o te haehae, te rewena, me ētahi huakita, ā, he tino pai mō ngā whāngai e pirau ana i ngā taiao makuku nui (hei tauira, ngā witi, ngā whāngai whakakotahi).
• Haumarutanga Teitei: Ka hurihia hei waikawa propionic (he waikawa ngako mekameka poto tūturu) i roto i ngā kararehe, ka uru ki te pākia o te pūngao. He iti rawa te paitini, ā, he whānuitia te whakamahinga i roto i ngā heihei, poaka, ngā manu ruminant, me ētahi atu.
• Pūmautanga Pai: Kāore te konupūmā propionate e waikura, he māmā ake te penapena, ā, he ōrite te whakaranu, he rerekē ki te waikawa propionic.

Ngā tono

• E whakamahia whānuitia ana i roto i ngā kararehe, heihei, whāngai ika, me ngā kai mōkai. Ko te horopeta e taunakitia ana ko te 0.1%–0.3% (whakarerekētia i runga i te makuku o te whāngai me ngā āhuatanga rokiroki).
• I roto i te kai a ngā ruminan, ka mahi anō hoki ia hei matūkai pūngao, e whakatairanga ana i te tipu o ngā moroiti o te rumen.

Ngā Whakatūpato

• Tērā pea ka pā kino te nui rawa ki te reka (he reka kawa ngawari), engari he iti iho i te waikawa propionic.
• Kia ōrite te ranunga kia kore ai e nui te kukū i te rohe.

Waikawa Benzoic i roto i ngā Taupānga Whāngai

Ngā Mahi

• Paturopi Whānui-Aromatawai: Ārai i ngā huakita (hei tauira,Salmonella,E. coli) me ngā pokepokea ai, me te whai huatanga nui ake i roto i ngā taiao waikawa (tino pai i te pH <4.5).
• Whakatairanga Tipu: I roto i te whāngai poaka (ina koa ko ngā poaka iti), ka whakaiti i te pH o te puku, ka pehi i ngā huakita kino, ka whakapai ake i te mimiti o ngā matūkai, ā, ka whakanui ake i te pikinga o te taumaha o ia rā.
• Te Pūnaha Whakaora: Ka honoa ki te glycine i roto i te ate hei hanga i te waikawa hippuric hei whakaputanga. Mēnā ka nui rawa ngā horopeta, ka nui ake pea te taumahatanga ki te ate/ngā whatukuhu.

Ngā tono

• E whakamahia ana i roto i ngā whāngai poaka (ina koa ngā poaka iti) me ngā heihei. Ko te horopeta kua whakaaetia e te EU ko te 0.5%–1% (hei waikawa benzoic).
• Ngā pānga mahi tahi ina honoa ki ngā propionates (hei tauira, te konupūmā propionate) hei whakarei ake i te aukati i te harore.

Ngā Whakatūpato

• Ngā Herenga Inenga Tino Pūmau: Kei ētahi rohe te herenga o te whakamahinga (hei tauira, ko ngā ture tāpiringa whāngai a Haina e here ana ki te ≤0.1% i roto i te whāngai poaka).
• Whai Huatanga e Āhua Ana ki te pH: Kāore i te tino whai hua ki ngā whāngai kūpapa/kawakore; he maha ngā wā ka honoa ki ngā mea whakakawa.
• Ngā Mōrearea Wā Roa: Ka whakararu pea ngā horopeta nui i te taurite o ngā moroiti puku.

Whakarāpopototanga Whakataurite me ngā Rautaki Whakaranu

Ngā Tuhipoka Whakahaere

• Haina: E whai anaNgā Aratohu Haumaru mō ngā Tāpiringa Whāngai—he iti rawa te waikawa benzoic (hei tauira, ≤0.1% mō ngā poaka iti), engari kāore he rohe whakarunga rawa o te konupūmā propionate.
• EU: Ka whakaaetia te waikawa benzoic i roto i te whāngai poaka (≤0.5–1%); kua whakaaetia whānuitia te konupūmā propionate.
• Ia Auaha: Ko ētahi kaihanga e pai ake ana ki ngā momo rongoā haumaru ake (hei tauira, te konutai diacetate, te pāhare pākawa waro) i te waikawa benzoic.

Ngā Whakaaro Matua

1. Mō te Whakahaere i te Poke: He haumaru ake te konupūmā propionate, ā, he maha hoki ngā whakamahinga mō te nuinga o ngā whāngai.
2. Hei Whakahaere me te Tupu o ngā Huakita: He tino pai te waikawa benzoic mō te whāngai poaka engari me tino kaha te horopeta.
3. Rautaki Tino Pai: Mā te whakakotahi i ngā mea e rua (me ētahi atu matū tiaki rānei) ka taurite te aukati i te harore, te mahi patu huakita, me te whai huatanga o te utu.
