Oiri yeOlive yave mafuta anodyika ane hutano anofarirwa nevatengi pasi rese nekuda kwehupfumi hwayo hwekudya uye kunhuhwirira kwakasiyana. Nekudaro, vanhu vazhinji vanowanzo furatira kuchengetwa kwemazuva ese kwebhodhoro remafuta kana vachichengeta mafuta emuorivhi, izvo zvinogona kuita kuti oxidize uye iparare, zvichikanganisa kunaka uye kuravira. Iyo chaiyo yekuchengeta nzira haingowedzere hupenyu hwesherufu yemafuta emuorivhi, asi zvakare ive nechokwadi chekuti kuravira kwayo uye kukosha kwekudya hakukanganiswe.
Chekutanga pane zvese, kusarudzwa kwezvinhu zvebhodhoro remafuta emuorivhi kwakakosha. Mabhodhoro egirazi ndiwo anonyanya kurongedza zvinhu, kunyanya rima regirazi mabhodhoro, anogona kunyatso kuvharira chiedza uye kunonoka oxidation yemafuta. Kusiyana neizvi, mabhodhoro epurasitiki akajeka kana midziyo yesimbi inowanzoita kuti mafuta aonekwe kune chiedza uye oksijeni, zvichikurumidza kuparara. Naizvozvo, zvinokurudzirwa kuti vatengi vape pekutanga mafuta emuorivhi akaiswa mumabhodhoro egirazi rakasviba uye edza kuchengeta iwo ekutanga kurongedza mushure mekutenga.
Chechipiri, nharaunda yekuchengetera ine chekuita kwakakura pamhando yemafuta emuorivhi. Mafuta emuorivhi anofanirwa kuchengetwa munzvimbo inotonhorera, ine rima, kudzivirira zuva rakananga uye yakanyanya tembiricha nharaunda. Iyo yakanaka yekuchengetedza tembiricha ndeye 15℃kusvika 20 degree. Kunyanya tembiricha inomhanyisa oxidation yemafuta uye kukonzera rancidity. Mukuwedzera, bhodhoro remafuta rinofanira kuchengetwa rakavharwa kuti rideredze kusangana nemhepo. Mushure mekushandisa kwega kwega, iva nechokwadi chekusimbisa chivharo chebhodhoro kudzivirira okisijeni kupinda mubhodhoro.
Kuchenesa bhodhoro remafuta zvakare chikamu chakakosha chekutarisira zuva nezuva. Kana bhodhoro remafuta richida kushandiswa zvakare, rinofanira kunyatsocheneswa uye kuomeswa kudzivirira mafuta akasara kubva pakubereka mabhakitiriya kana oxidation uye kuora. Paunenge uchichenesa, shandisa mvura inodziya uye yekugezesa isina kwayakarerekera, uye dzivirira kushandisa alkaline yakasimba kana yakasimba asidhi detergent kudzivirira makemikari asara kubva pakukanganisa kunaka kwemafuta. Mushure mekuchenesa, bhodhoro rinofanira kupindurwa pasi kuti riome, uye iva nechokwadi chokuti mukati wakaoma zvachose usati wadzorera mafuta emuorivhi.
Pakupedzisira, zvakakoshawo kutarisa mamiriro ebhodhoro remafuta nguva dzose. Kana bhodhoro remafuta richiwanikwa rakatsemuka, rakaremara kana kuti risina kuvharwa zvakasimba, rinofanira kutsiviwa nenguva kuti rirege kukanganisa kuchengetedza kwemafuta emuorivhi. Pamusoro pezvo, zvinokurudzirwa kushandisa mafuta emuorivhi mukati memwedzi mitanhatu mushure mekuvhurwa kuti ive nechokwadi chekunaka uye kukosha kwekudya.
Kuburikidza nekutarisira kwakaringana kwezuva nezuva, vatengi vanogona kuchengetedza mafuta emuorivhi zvirinani uye kuwedzera hupenyu hwayo, uku vachiona kuti donhwe rega remafuta rinoramba riri nyowani uye rine hutano. Kubata aya matipi akareruka ekutarisira hakungogone kuvandudza mhando yemafuta emuorivhi, asiwo kupa kuchengetedzwa kuri nani kwekudya kune hutano.
