He nui ngā ārai e hiahiatia ana i roto i te tukanga purenga o raro o ngā rongoā koiora. He nui te pānga o te tika me te āheinga ki te whakaputa anō i ngā ārai ki te tukanga purenga pūmua. Ka taea e te pūnaha whakaranu ipurangi me te pūnaha inenga ipurangi te whakakotahi i ngā momo ārai kotahi-wāhanga. Ka whakaranua te wai whaea me te wai whakamātao ipurangi kia whiwhi ai i te otinga ūnga. Kei runga i te mātauranga pūtaiao te hua, ā, ko te kounga i ahu mai i te ariā o te hoahoa (QbD). Mā te aroturuki me te whakahaere ipurangi tūturu (tūturu i te wā) o ngā tohu matū e rua, ngā āhuatanga kounga matua (CQA) o te hua (CQA), te pH me te kawe hiko i te wā o te tukanga whakaputa, kia whakarite kia whakaratohia he ārai kounga pumau me te ōrite mō ngā tukanga o raro hei āwhina i ngā kaupapa tuku tawhā a ngā kamupene rongoā koiora. Ko te tukanga whakarite wai tuku iho e hiahia ana ki te maha o ngā tāke me te nui o te rōrahi. Ka kawea mai e IVEN ki ngā kiritaki he wheako hangarau hou, ka whakaiti i te tapuwae o te inenga ārai i te wāhanga tukanga purenga, me te whakaiti i ngā utu i mua i te haumi me te muri i te whakaputa me te whakahaere. , Whakapai ake i te whai huatanga o te whakaputa, whakarite i ngā tawhā tukanga matua (CPP) o te arai me tōna whai i te whai, ā, hei whakamutunga, whakapai ake i te kounga o ngā rongoā.
