Nthambi ndi yovuta, yosanjikiza ya mbewu zonse zopangira mafuta monga oats, tirigu, mpunga, rye ndi ena.
Njere yambewu imakhala ndi endosperm, yomwe ndi gawo lalikulu la mbewu zomwe zimagwiritsidwa ntchito popanga ufa.
M'kati mwa endosperm ndi nyongolosi (yochepa kuti "ikhale"), yomwe imakhala ndi mapuloteni komanso zakudya zina, ndipo imakhalanso ndi magulu osiyanasiyana a mafuta oyenera.
Kuzungulira nyongolosi ndi endosperm ndi nthambi, yomwe nthawi zina imatchedwa "branchi ya miller" chifukwa nthawi zambiri imachotsedwa panthawi yopuma.
Nthambi imakhala ndi mapuloteni, zitsulo, zitsulo, mavitamini, mafuta acids komanso zakudya zina monga mavitamini a B.
Kulankhulana bwino, kulekanitsa kachilombo ka mbewu ndi udzu kuchokera ku tirigu musanayambe kuwagwiritsa ntchito ufa. Mwinamwake chifukwa chachikulu cha chizoloŵezi ichi chinali chakuti nyongolosi ndi nthambi zimakhala ndi mafuta acids omwe angakhoze kupita pang'onopang'ono. Choncho, ufa wopangidwa kuchokera ku tirigu umene wakhala ndi branchi ndi majeremusi anachotsa chiphunzitsochi chidzakhala ndi moyo wazitali.
Komabe, kuti ufa wonyezimira woyera umakhala ndi zakudya zochuluka zowonongeka ndi chifukwa chake ufa umakhala "wopindulitsa" mwa kuwonjezera mavitamini mu ufa pasanapite nthawiyo. Sizodziwika ngati kuwonjezerapo mavitamini mu ufa ndikumveka bwino ngati kuzisiya kumbewu kumalo oyamba, motero kuchokera ku zakudya, mumakhala bwino kugwiritsa ntchito ufa wa tirigu wonse.
Pano pali nkhani yokhudza mitundu yosiyana ya ufa wa tirigu .
Nthambi: Ndi Chimene Chimachititsa Brown Rice Brown
Mchenga uli ndi mzere wa chimanga kunja kwa njere iliyonse, yomwe ndi kusiyana kwakukulu pakati pa mpunga woyera ndi mpunga wofiira. Mchele wa Brown uli ndi mpweya wosakanikirana wa mphutsi pamene mpunga woyera watha kuchotsa panthawi yopuma.
Matenda omwewo alipo ndi kuchotsedwa kwa branchi ku mpunga monga mbewu zina.
Ndipo ndithudi, mpunga woyera ndi wofanana "wopindulitsa" chifukwa chomwecho.
Mpunga woyera (wopanda bran) amaphika mofulumira kuposa mpunga wofiira. Pano pali nkhani yokhudza kuphika mpunga wofiira .
Kuphika Ndi Nthambi
Mukhoza kugula thumba la chinangwa cha tirigu (kaya mu sitolo kapena pa intaneti), ndiyo njira imodzi yokha yopangira chimbudzi cham'mimba (ngakhale maphikidwe ena amangotchula kuti chimanga). Kulankhula za izi, apa pali njira ya pulasitiki yamakina , zomwe ndi zodabwitsa kupeza.
