Ko te Waikawa Propionic (CAS 79‑09‑4), he waikawa carboxylic maha-whakamahinga e whakamahia whānuitia ana i roto i te tiaki kai kararehe, ngā tāpiringa kai, ngā takawaenga rongoā me te hanga matū pai, e kukume ana i te aro nui o te mākete i te mutunga o Hepetema 2026, nā ngā whanaketanga hangarau ā-rohe me te tipu o te tono ā-wā puta noa i ngā rāngai ahuwhenua o te ao.

I te 16 o Hepetema, i tutuki i te Sinochem Southwest Research Institute tētahi tohu hangarau nui. Ko tana tipu whakamātautau 100 tana ia tau mō te methyl propionate mā te ethylene hydroesterification i mahi pumau mō te neke atu i te 300 hāora karapīpiti. I tuhia e te tukanga neke atu i te 99% te huringa kotahi-haerenga o te waro hauota me te neke atu i te 99.9% te whiriwhiringa methyl propionate, he tohu matua ki te whakaputa matomato hou mō ngā matū raupapa propionate tae atu ki ngā matū waikawa propionate. Whai muri i te whakamana katoa o ngā raraunga whakamātautau, ka panaia e ngā rōpū e tika ana te hanganga tauine ahumahi. E tumanakohia ana ka hurihia e tēnei huarahi auaha te whenua tuku roa o ngā takawaenga e pā ana ki te waikawa propionic teitei-parakore i Haina, e tautoko ana i ngā matū hiko-mākū, ngā mea kakara me te hanga rauemi rongoā.

Mō ngā kaupapa matua o te mākete, ko te hauwhā tuawhā te wā e kai nui ai te waikawa propionic mō te whāngai kararehe. Ka whakanui ake ngā kaihanga kararehe i Amerika ki te Tonga, Āhia ki te Tonga-mā-rāwhiti me Āwherika i te hoko o ngā tāpiringa ārai-haehae i mua i te rokiroki witi o te takurua. Ka pehia e te waikawa propionic te whakaputa uri o te haehae me te mycotoxin i roto i te whāngai me te silage, e pupuri ana i te uara kai o te whāngai me te whakaiti i te para o ngā rauemi mata. Kei te whakaitihia e ngā kaihanga whāngai o te ao ngā tāpiringa paturopi, ka piki ake te hiahia o te mākete mō ngā matū tiaki waikawa waro.

I Haina, ka mau tonu ngā reiti mahi pumau a ngā kaihanga waikawa propionic matua. Ko te tuku wā-tūturu he taurite i waenga i ngā ota kounga ahumahi, kounga kai me te kounga whāngai. Kua piki ake ngā tono kaweake mai i ngā kiritaki ahuwhenua me te tukatuka kai o tāwāhi mai i waenganui o Hepetema. He nui te hiahia o ngā kaihoko ki te waikawa propionic 99.5% te parakore, me ngā kōwhiringa takai ngāwari tae atu ki ngā pū, ngā putea IBC me ngā ipu tāke ISO mō ngā whakaritenga tuku rerekē.

Ahakoa rā, kei te mātakitaki tonu ngā kaiuru o te mākete i ētahi āhuatanga mōrearea. Tērā pea ka pāngia ngā kaihanga waikawa propionic e ngā piki me ngā heke o te utu o ngā rauemi mata. Haunga tēnā, ka pā tonu te whakataetae ā-rohe mai i ngā kaiwhakarato o tāwāhi ki ngā hua kaweake. E tohu ana ngā kaitātari ahumahi ka tautokona te mākete waikawa propionic mō te wā poto e te tono whāngai ā-wā. Heoi, kāore pea e piki ake ngā utu mena kāore he iti o te tuku. E taunakihia ana kia whakarite ngā kaihoko o te ao i ngā ota i mua i te wā kia pai ai te whakatau i te pēhanga o te tuku i te hauwhā 4. I te wā roa, mā ngā hangarau hanga matomato hou kua whakawhanakehia e whakapai ake te painga whakataetae o Haina i roto i te hokohoko propionic-derivatives o te ao.
