Potassium diformateHe momo tote waikawa waro, he tino pirau, he ngāwari ki te whakahaere, kāore e waikura, kāore e paitini ki ngā kararehe me ngā heihei. He pumau i raro i ngā āhuatanga waikawa, ā, ka taea te wawahi ki te pāhare pākawa me te waikawa formic i raro i ngā āhuatanga kūpapa, kawakore rānei. Ka mutu ka pakaru ki te CO2 me te H2O i roto i ngā kararehe, ā, kāore he toenga i roto i te tinana. Ka taea e ia te aukati i ngā mate pukupuku o te puku. Nō reira, kua whānuitia te whakanui i te pāhare pākawa dicarboxylate hei whakakapi mō ngā paturopi, ā, kua whakamahia i roto i te whakatipu kararehe me te heihei mō te tata ki te 20 tau i muri i te whakaae a te EU ki te pāhare pākawa dicarboxylate hei whakakapi mō te tāpiringa kai whakatairanga tipu paturopi.

Te whakamahinga o te pāhare pākawa dicarboxylate i roto i te kai heihei

Mā te tāpiri i te 5g/kg pāhare pākawa waro ki te kai heihei parai ka nui ake te taumaha o te tinana, te tere o te patunga, te whakaiti i te tere o te hurihanga kai, te whakapai ake i ngā taupū ārai mate, te whakaiti i te uara pH o te puku, te whakahaere pai i te mate huakita o te puku me te whakatairanga i te hauora o te puku. Mā te tāpiri i te 4.5g/kg pāhare pākawa waro ki te kai ka nui ake te taumaha o ia rā me te utu kai o ngā heihei parai, ka rite te hua ki te Flavomycin (3mg/kg).

Nā te kaha patu huakita o te pāhare pākawa waro o te pāhare pākawa waro i whakaiti te whakataetae i waenga i te moroiti me te kaihautū mō ngā matūkai me te ngaronga o te hauota taketake. I whakaitihia hoki te maha o ngā mate pāwera iti me te hunanga o ngā takawaenga ārai mate, ā, ka whakapai ake i te nakunaku o te pūmua me te pūngao me te whakaiti i te whakaputanga o te haukini me ētahi atu matūkai e ārai ana i te tipu; I tua atu, mā te whakahekenga o te uara pH o te puku ka taea te whakaoho i te hunanga me te mahi o te trypsin, te whakapai ake i te nakunaku me te mimiti o ngā matūkai, te hanga i ngā waikawa amino kia pai ake ai te whakatakoto i te pūmua ki roto i te tinana, kia pai ake ai te tere hiroki o te tinana. I kitea e Selle et al. (2004) ko te taumata pāhare pākawa waro kai i te 6G/kg ka taea te whakanui ake i te nui o te kai me te kai whāngai o ngā heihei parai i ia rā, engari kāore he pānga nui ki te whai huatanga o te whāngai. Ko te taumata pāhare pākawa waro kai i te 12g/kg ka taea te whakanui ake i te whakatakoto hauota mā te 5.6%. I whakaatuhia e Zhou Li et al. (2009) ko te pāhare pākawa waro kai i whakanui ake i te nui o te kai i ia rā, te tere hurihanga whāngai me te nakunaku o ngā matūkai whāngai o ngā heihei parai, ā, he mahi pai ki te pupuri i te whanonga noa o ngā heihei parai i raro i te pāmahana teitei. I kōrero a Motoki et al. (2011) ka taea e te 1% pāhare pākawa dicarboxylate kai te whakanui ake i te taumaha o ngā heihei tunu, te uaua o te uma, te huha me te parirau, engari kāore he pānga ki te whakatakotoranga hauota, te pH o te puku me te microflora o te puku. I kitea e Hulu et al. (2009) mā te tāpiri i te 6G/kg pāhare pākawa dicarboxylate ki te kai ka taea te whakapai ake i te kaha pupuri wai o te uaua, me te whakaiti i te pH o ngā uaua o te uma me te waewae, engari kāore he pānga nui ki te tipu. I kōrero a Mikkelsen (2009) ka taea hoki e te pāhare pākawa dicarboxylate te whakaiti i te maha o ngā Clostridium perfringens i roto i te puku. Ina 4.5g/kg te nui o te pāhare pākawa dicarboxylate kai, ka taea te whakaiti i te mate o ngā heihei tunu me te necrotizing enteritis, engari kāore he pānga nui o te pāhare pākawa dicarboxylate ki te tipu o ngā heihei tunu.

Te tāpiripāhare pākawa waroHei whakakapi i te kai kararehe, ka taea e te rongoā paturopi te whakatairanga i te nakunaku me te mimiti o ngā matūkai o te kai, te whakapai ake i te tipu me te tere hurihanga o te kai o ngā kararehe, te whakahaere i te hanganga o te microflora o te puku, te aukati i ngā huakita kino, te whakatairanga i te tipu hauora o ngā kararehe, me te whakaiti i te mate.
