Wai pītiti kukūHe tukanga hanga paerewa te whakaputa e huri ana i ngā pītiti hou hei hua kua oti te wairewa-teitei. Ko tōna whāinga matua he pupuri i te reka tūturu, te tae me te kai totika o ngā pītiti hou. Ko te hua whakamutunga ka eke ki te 65% ~ 70% o ngā totoka wairewa, ā, he whānuitia te whakamahinga i roto i te whakaranu inu, ngā hua miraka, te tunu kai me ētahi atu mara.
1. Te Maimoatanga o ngā Rauemi Mata: Mai i ngā Hua Mata ki te Penupenu Ārai-tae
Koinei te tīmatanga hei whakapūmau i te kounga taketake o te hua kua oti, e whakatau tika ana i te pumau o te reka me te tae i muri mai.
- Te Kōwhiringa me te Horoi i ngā Hua: Tīpakohia ngā pītiti hou kua 80%~90% te pakeketanga, kāore he pepeke me ngā mate, ā, he ōrite te ōwehenga huka-waikawa, tangohia ngā hua pirau me ngā hua hapa. Horoia ki te wai ma; mō ngā pītiti he huruhuru matotoru, ka taea te whakamahi i te paraihe horoi. Mena e tika ana, ka taea te whakamahi i te patu huakita kai hei patu huakita i te mata, kātahi ka horoia rawatia ngā toenga.
- Te Tātari me te Kuru: Wehea ngā pū pītiti ki te mīhini tātari, kuruhia te penupenu kia rite te rahi o te matūriki ki te 2~3mm. Me karo i ngā matūriki nunui rawa hei ārai i ngā pānga kino ki te hua wai o muri mai.
- Maimoatanga Tiaki Tae: Tāpirihia he 0.05%~0.1% huaora C, he nui rānei o te waikawa citric e tika ana i te wā e kuruhia ana hei aukati i te parauri whākōkī, hei ārai i te hurihanga o te tae o te penupenu pītiti, ā, kia mārama ai te tae koura o te hua whakamutunga.
2. Te Whakawai me te Whakamārama: Te Whakapai ake i te Hua Wai me te Pūmautanga o te Hua
Mā tēnei wāhanga ka whakatauhia te whai huatanga o te tango wai, te whakawhiti mārama o te wai kukū me te kaha ki te ārai i te ua i te wā e ora ana.
- Tango Wai: Whakamahia he mīhini pēhi tīwiri, he mīhini pēhi putea hau rānei hei tukatuka i te penupenu pītiti, kia eke ai te hua wai ki te neke atu i te 70%. Ka taea te tāpiri i tētahi iti o te whākōkī penupenu i mua i te whakapūtanga hei āwhina i te pirau o te pectin me te whakapai ake i te whai huatanga o te tango wai.
- Tātari Taratara me te Tango Para: Tātarihia te wai pītiti kua tangohia mā te whakamahi i tētahi mata tātari 60~100 mata hei tango i te muka mata me ngā para penupenu nui, kia whiwhi ai i te wai pītiti mata kua mārama i te tīmatanga.
- Te Whakamāramatanga Whākōkī: Tāpirihia te pectinase (0.0125%~0.02%) me te iti o te amylase ki te wai pītiti mata, ka whakahaere i te waikura whākōkī i te 50~55℃ mō te 1~3 hāora hei wawahi katoa i te pectina macromolecular i roto i te wai, kia kore ai e whakarōpūtia me te maturuturu i te wā e rongoatia ana i muri mai.
- Tātaritanga me te Whakama: Whakamahia te tukanga whakakotahi o te tātari pereti-me-angi me te kiriuhi tātari-rahi (rahi o te kōhao 0.5~0.8μm) hei aukati katoa i ngā colloids toenga, ngā heteroproteins me ngā totoka whakatārewatia pai, ā, ka puta he wai mārama me te whakawhiti māramatanga teitei me te pumau kaha.
3. Tukanga Arotahi: Hononga Hangarau Matua
E rua ngā tukanga matua e wātea ana hei whiriwhiri mā te tūnga o te hua, ko te kaupapa matua ko te karo i te kino o te pāmahana tiketike ki ngā matū kakara e pāngia ana e te wera.
- Te Kukū Pāmahana Iti Korehau (Tukanga Whānui Matua): Whakarewahia, ka maroke i raro i te pēhanga iti i te 50~60℃ me te nekehanga korehau o te 0.08~0.095MPa, ka whakanui ake i te totoka wairewa o te wai pītiti mai i te 10%~12% tīmatanga ki te 65%~70%. Ka tino whakaitihia e tēnei tukanga te whakangaromanga o te kakara pītiti e te pāmahana teitei, ā, ka whakaitihia ngā utu rokiroki me te kawe i muri mai.
- Te Kukū o te Kiriuhi Pāmahana Noa (Tukanga Hua Tino Pai): Whakamahia te kiriuhi nanofiltration mō te whakamaroke tinana i te pāmahana noa o te 25~35℃, me te kore he huringa āhua i roto i te tukanga katoa. Ka taea e te tere pupuri o ngā matū kakara me ngā huaora te eke ki te neke atu i te 98%, tata kore he "reka kua tunua", ā, he iti ake te whakapaunga pūngao i te kukū mimiti tuku iho. He pai mō te whakaputa wai pītiti kukū tino pai, he nui te uara tāpiri.
- Whakapaipai Whakaora Kakara: Ko ngā raina whakaputa kounga teitei he taputapu whakaora matū kakara pūngāwerewere, e whakapūpū ana, e kohi ana i te kakara pītiti i puta mai i te wā o te tukanga kukū, kātahi ka tāpirihia ki te wai kua oti te hanga hei whakaora i te kakara tūturu o ngā pītiti hou.
4. Te Whakaranu me te Tango Hau: Te Whakapai Ake i te Reka me te Kounga
I muri i te whakarerekētanga o te huka me te waikawa ki ngā uara ūnga e ai ki ngā paerewa hua, me tango te hauhautanga mā te korehau hei tango i te hāora rewa i roto i te wai, hei whakaiti i te tae korehau me te kino o te reka i te wā e rongoa ana i muri mai, ā, hei karo hoki i te huka i te wā e whakakī ana ka pā ki te pānga hiri.
5. Te Whakahoromata me te Whakakī: Kia Haumaru, kia Roa te Ora
- Maimoatanga Whakahoromata: Whakatairangahia te whakahoromata tere i te pāmahana tino teitei o te UHT, puritia mō ētahi hēkona i te 110~120℃, whakamahia rānei te whakahoromata i te 95℃ mō te 30 hēkona, ka taea ai te whakamate katoa i ngā moroiti, me te whakaiti hoki i te kino ki te reka me te kai.
- Whakakī Ārai Mate: Whai muri i te whakahoromata, whakamatao wawe ki te pāmahana noa, ka whakakīia te wai kukū ki roto i ngā ipu ātete mārama, hiri hoki, he pai mō te kai, i roto i te taiao ārai mate. Ka taea te penapena i te hua kua oti mō te wā roa i te pāmahana iti o te 0~5℃, he pumau te kounga, ā, kāore e ngāwari te pirau.
