Huchi mazai ndeimwe yezvinhu zvakakosha zvakagadzirwa nevanhu. Kuumbwa kweii yeiyi kunosanganisira kudiwa kwekushanda kwemapuroteni emuviri nemafuta, uyewo zvakasiyana-siyana zvinoshandiswa zvehupenyu zvikamu - vitamini , micro-uye macro zvinhu.
Kemikari yakakonzerwa namai mazai
Iyo makemikari emukoko wekuku ane:
- mvura 74%;
- Mapuroteni - 12.5%;
- mafuta - 12%
- carbohydrates - 0,5%;
- mineral elements uye mavitamini - 1%.
Kuumbwa kwemapuroteni ezai yekuku kunopesana nekuumbwa kwejecha, pakuti haina mafuta uye rine mvura yakakwirira. Uye yolk, kusiyana nemaprotein, ine madiki mashoma amino acids. Simba rinokosha rehai yekuku is 47 kcal (157 kcal ne 100 g). Chimwe chikamu chinokosha che caloric zvine mazai evha (75%) ndeyomukati.
Mapuroteni anopa kukosha kwakakosha kweii yei. Amino acids mukuku mazai anochengeterwa zvakaenzana, saka vanobatwa nemuviri anenge 100%. Nokuda kwechikonzero ichi, vanhu vanononoka uye vatambi vemasimba vanowanzoshandisa mazai ega chete.
Iyo yekasi yeii yeiyi chikamu chetatu chemafuta, chikamu chikuru cheicho chinonyanya kukosha unsaturated mafuta acids. Kurwisana pamusoro pengozi uye kubatsirwa kweiii yolk pakati pevanhu vanofa vanochemera cholesterol. Zvisinei, mune rimwe dza hazvisi zvakawanda - zvishoma kudarika kwezuva nezuva. Zvakare - yolk cholesterol "haigadziriswi" nedzimwe chikamu chezai - lecithin.
Kushandiswa kwamazai kunowedzera huwandu hwakawanda hwevhithamini (A, E, PP, D, H, K neboka B), uyewo mineral composition, iyo inosanganisira calcium, phosphorus, magnesium, potassium, sodium, sulfuri, iron uye zvimwe zvinoda hutano zvikamu.
Kutaura pamusoro pekuumbwa kweii yei, haugone kukanganwa pamusoro payo. Icho chikuru chechikamu - calcium, asi inosanganisira mamwe makumi matatu anokosha emaminerari.
Kukuvara kwekuku mazai
Pamusana pezvakanyorwa zve ovomucoid protein muzai, chigadzirwa ichi chinonyanya kureba. Ovomukoid inokonzera kukanganisa mukugadzirwa kwemakemikari nepancreas, iyo inotungamirira kusina kukwana kwekudya kwezvokudya uye kuwedzera kwezvinokonzera zvirwere. Deredzai zvinyorwa zviri mukudya mazai zvinofanira kunge zvine hutachiona hwehupembenene, chirwere chechiropa, zvepvo uye gallbladder, zvirwere zveganda. Mukuwedzera, mazai anogonawo kuva mishonga yebhakitiriya yepathogenic. Imwe yepathogenic ndeye salmonella. Kuti dzidzivirire kurwisana nemakiromita aya, vanachiremba vanokurudzira kubika mazai mushure maminitsi masere mushure mokubikira.
