Mphero yachikhalidwe ndiyo njira yokhayo yotsimikizira kuti umphumphu, mtundu wake, kununkhira kwake komanso phindu lake la ufa. Izi ndichifukwa choti tirigu wathunthu amapendedwa kamodzi komanso pakati pa miyala iwiri yopingasa, yozungulira, yosunga ndikuphatikiza mafuta a tirigu. Njirayi ndi pamtima pa mphero zachikhalidwe. Palibe chomwe chimachotsedwa, kapena kuwonjezeredwa - tirigu wathunthu amalowa, ndipo ufa wathunthu umatuluka.

Ndipo ndiye mfundoyi. M'dziko lake lonse tirigu mumakhala masitala achilengedwe, mapuloteni, mavitamini, ndi michere. Mu tirigu, mafuta ambiri ndi mavitamini ofunikira a B ndi E amaphatikizidwa ndi nyongolosi ya tirigu, mphamvu yambewu. Ndi kuchokera ku nyongolosi ya tirigu pomwe njere zimamera zikavekedwa papepala lonyowa kapena ubweya wa thonje. Nyongolotsi ya tirigu yochuluka onunkhira komanso yopatsa thanzi imatha kupatulidwa pogaya miyala, ndipo imapatsa ufawo kukoma kwa mtedza. Ngakhale ufa wa wholegrain ndiwofunikira, ufa wapansi pamiyala umasungabe mtundu wina wa nyongolosi ya tirigu ngati itasungunulidwa kuti ipange ufa wopepuka wa "85%" (wokhala ndi 15% ya chinangwa) kapena ufa "woyera".

Mphero zamakono zamakono, mosiyana, ndizapadera, komanso zothandiza kwambiri, zopangidwa kuti zichotse ufa woyera wonse momwe zingathere pa njere iliyonse. Makina othamanga othamangitsa osanjikiza, sungani, kenako chotsani chosanjikiza china, ndi zina zambiri. Tinthu tating'onoting'ono ta ufa titha kuyenda mtunda wopitilira kilomita imodzi pakati pa ma roller ndi sieve. Imathandizira kuti nyongolosi ya tirigu ndi chinangwa ichotsedwe bwino, ndipo imatha kupanga ufa wochuluka mwachangu komanso mosavutikira anthu. Ndizotheka kuphatikizanso ndikusakaniza zinthu zingapo zosanjidwa, koma sizofanana ndi ufa wamiyala wathunthu wazakudya - sizomwe zimapangidwira.
