Mō ngā hua horoi taiao mō te kāinga, ko ngā mea tuatahi ka puta ake ki te hinengaro ko te winika mā me te houra tunutunu. Engari kāore i te herea ki ēnei mea e rua anake; he pono, kei reira anō ētahi atu hua horoi taiao he whānuitia ngā whakamahinga mō te kāinga, ā, i ētahi wā he pai ake te mahi.
Tērā pea ka āhua māharahara koe i te tīmatanga i te mea he mea horoi kākāriki e kīia nei ko te "waikawa citric". Engari he mea horoi whare waikawa rongonui kua roa e whakamahia ana—i tangohia tuatahitia mai i te wai rēmana i te mutunga o te rautau 1700. Nā, me pēhea te horoi a te waikawa citric? Kua kohikohia e mātou e whitu ngā tikanga horoi kāinga hei āwhina i a koe ki te whakamahi pai rawa atu.
I mua i tā tātou ruku ki ngā whakamahinga o te waikawa citric, me mārama tātou ki te tikanga o tēnei mea. He rite tonu ngā āhuatanga horoi o tēnei paura, i ahu mai i ngā hua citrus, ki te waikawa citric noa, engari he nui ake te whai huatanga. He waikawa, e ngāwari ai te tango i te paru raima, ā, he pānga whakama hoki tōna. Inaa, he maha ngā wā ka tūtohutia hei whakakapi mō te winika mā kua whakakorengia.
Heoi, he rerekētanga kei waenganui i ngā mea e rua. I mea a Tākuta Joanna Buckley, te kaiwhakahaere mātauranga i te Royal Society of Chemistry: "He matū hohe te waikawa citric me te winika i roto i te maha o ngā horoi whare, ā, he whai hua ngā mea e rua. Ko te pH o te winika kei waenga i te 2 me te 3, ā, he waikawa kaha - ko te iti o te pH, ko te nui ake o te waikawa. He paku teitei ake te pH o te waikawa citric (pērā i te mea e kitea ana i roto i ngā hua citrus), nō reira he paku iti ake te waikawa. Nō reira, he paku iti ake te mōrearea o te kino o ngā mata ngawari, ā, he painga anō hoki ko te waiho i tō kāinga kia kakara hou, kaua ki te rite ki te toa ika me te parai!"
Heoi anō, he matū kawa tonu te waikawa citric, nō reira, kāore e pai mō ngā mata katoa. E whitu ngā wāhi kāore e tika kia horoia ki te winika, kāore hoki te waikawa citric e pai mō te kōhatu maori, ngā papa rakau me ngā mata. Kāore hoki te konumohe e pai.
Haunga te horoi i te whare, ka taea te whakamahi i te waikawa citric ki te tunu kai, hei mea kakara, hei tiaki kai hoki. Heoi, me tirotiro tonu i mua i te wā mēnā he pai te waitohu i whiriwhiria e koe mō te tunu kai. He waitohu rongonui a Dri-Pak, engari ehara tēnei takai i te "haumaru mō te kai," nō reira me whakamahi noa mō te horoi.
Ahakoa he haumaru te whakamahi i te waikawa citric, he mea pai kia mau karapu i te wā e horoi ana hei tiaki i tō kiri. Hei tāpiri, me mau he mōhiti haumaru me te kopare hei ārai i te hongi o te waikawa citric.
Pērā i te winika mā kua whakakorengia, ka taea e koe te whakaranu i te waikawa citric hei hanga i tētahi kaihoroi mata. Whakaranua noa kia 2.5 punetēpu o te waikawa citric ki te 500 ml o te wai mahana ki roto i tētahi pounamu rehu kau, rūrūtia kia pai, ā, whakamahia te ranunga hua hei rehu i ngā papa laminate, ngā papa kirihou me ngā papa maitai puta noa i tō whare.
Kia mōhio mai he otinga waikura tēnei, nō reira kaua e whakamahia ki runga i ngā mata kōhatu maori, ki ngā mata rakau rānei.
He mea rongonui te winika hei tango i ngā paru, engari he rite tonu te whai huatanga o te waikawa citric. Tuatahi, whakakīia te ipu wai kia haurua ki te wai, kātahi ka tahuri te ahi. Whakawetohia te hiko i mua i te koropupū o te wai; ko te whāinga kia mahana tonu te wai.
Momotuhia te hiko o te ipu, tāpirihia kia rua punetēpu o te waikawa citric ki te ranunga, waiho kia 15-20 meneti kia mahi (kia mahara ki te waiho i tētahi tuhipoka kia kore ai e whakamahia e tetahi i tēnei wā!). Ringihia te wai, ka kohuatia he wāhanga hou o te wai hei tango i ngā toenga katoa.
Mena kei te ahua hina te tae o ō kākahu mā, ā, kāore he rēmana i a koe, ka taea hoki e te waikawa citric te āwhina. Whakaranua kia toru punetēpu o te waikawa citric ki te whā rita wai mahana, ka whakaoho kia memeha rawa. Kātahi ka rumakina te kākahu i te pō, ā, ka horoia ki te mīhini i te aonga ake. Ka āwhina anō hoki tēnei ki te rongoā i mua i ngā paru.
Whakamahia te waikawa citric hei whakaora i ngā oko karāhe e ngāwari ana ki te tauine me te kohu. Tauhiuhia noa te waikawa citric ki roto i te wāhanga hopi horoi o tō mīhini horoi rihi, ka whakahaere i te huringa noa me te kore hopi horoi, ka whakatakotoria ngā oko karāhe ki te whata o runga. Kia oti, ka hoki anō ō oko karāhe ki tōna āhua taketake, ā, he painga anō tēnei mō te tango i te tauine o tō mīhini horoi rihi i te wā kotahi.
Hei tango i te paru paru huna i roto i tō wharepaku, ringihia he peere wai wera ki roto i te peihana, ka tāpirihia he kapu waikawa citric. Tukua kia rewa, kia mahi mō te haora pea (he pai ake mō te pō) i mua i te horoinga i te rā e whai ake nei.
Kia mau tonu te āhua hou o ō whakaata me ō matapihi ki te winika mā, engari kaua e haunga! Whakaritea noa te horoi mata e ai ki te whakaahuatanga i runga ake nei, rehuhia ki ō whakaata me ō matapihi, kātahi ka murua ki te kakahu karāhe maikoro-mipere i roto i te nekehanga porowhita mai i runga ki raro. Mena he uaua ki te tango i te paru raima, waiho kia noho mō ētahi meneti i mua i te murunga.
He huarahi rongonui te rēmana hei horoi i tō ngaruiti, engari he pai anō te waikawa citric! I roto i tētahi peihana haumaru mō te ngaruiti, whakaranua kia 2 punetēpu o te waikawa citric ki te 500 ml o te wai wera. Whakaohokia kia memeha rawa, kātahi ka whakamahana i roto i te ngaruiti kia puta mai te mamaoa ki roto. Katia te tatau o te ngaruiti ka waiho mō te 5-10 meneti. Kia mātao te wai, murua te wai e toe ana ki tētahi kakahu ngohengohe. Kia mātao rawa te wai, ka taea hoki te whakamahi hei muru i tō ngaruiti.
