Casein kua nplaum tuaj yeem raug cais raws li kev muab tshuaj txhuam ntawm cov tsiaj keeb kwm. Nws muab tau los ntawm cov protein mis tshwj xeeb hu ua casein. Li no lub npe.
Cas casein kua nplaum yuav sib tov?
Nws paub tias casein kua nplaum tuaj yeem tau los ntawm mis protein. Thaum pib ntawm lub xyoo pua puv 19 nyob hauv lub teb chaws Yelemees thiab Switzerland, nws pib pib tsim los ntawm kev ntsuas ntawm qhov ntsuas kev lag luam. Hauv kev siv cov txheej txheem ntawm cov nplaum zoo li no, feem ntau tsis muaj teeb meem tshwm sim. Piv txwv li, rau kev npaj tus kheej ntawm cov kua nplaum casein, koj yuav tsum tau zom cov nqaij rog uas tsis muaj roj ntau los ntawm sab cib thiab yaug hauv dej sov. Tom qab ntawd ammonia yog tsuas yog ntxiv rau lub gruel resulting. Qhov tshwm sim yuav tsum tau muaj cov tshuaj translucent gelatinous. Nws tuaj yeem siv rau cov ntoo txua ntoo ua haujlwm.
Koj tuaj yeem coj los ua cov kua nplaum casein rau lwm txoj kev. Cov mis uas muaj roj tsawg yuav tsum tau lim siv cov ntawv tshwj xeeb lim. Tom qab ntawd tus lim dej yuav tsum tau muab ntxuav dua dej, muab tso rau hauv ib qho thau ntim thiab hau. Los ntawm txoj kev, npau npau yog tsim nyog los tshem tawm cov lipids. Nws raug nquahu kom ua kom cov ziab zom zaws tom chav sov li qub. Nov yog li cas cov rooj plaub qhuav. Tom qab ntawd casein yog sib xyaw nrog dej thiab sodium borate. Raws li qhov tshwm sim, cov tshuaj kis cov nplaum ua cov khoom.
Mis nyuj kua nplaum kua nplaum tseem tuaj yeem tsim kev lag luam. Rau qhov no, lub rennet hu ua ntxiv rau skim mis ua khoom lag luam. Qhov zoo siab, qee zaum cov lactic acid tuaj yeem siv los ua ke cov kua nplaum.
Cov yam ntxwv thiab daim ntawv thov ntawm kua nplaum
Casein kua nplaum yuav tsum muaj cov tshuaj nitrates, calcium calcium thiab cov phosphates mis. Mis protein tsis yaj hauv dej, tab sis pauv nws txoj hauv kev hloov thaum alkaline lossis acidic raug. Los ntawm txoj kev, casein nws tus kheej muaj tag nrho cov teeb meem ntawm cov amino acids.
Mis kua nplaum cov kua nplaum yog siv tshwj xeeb rau gluing cardboard, ceramic, porcelain, tawv thiab yas khoom. Tsis tas li, nws qhov kev siv yog cuam tshuam rau faience thiab polystyrene. Nws yog feem ntau pom zoo kom ua cov khoom ntoo nrog cov kua nplaum no. Vim tias cov khoom tshwj xeeb ntawm cov khoom siv no, cov qauv ntoo tau tuaj yeem ua kom zoo dua qub. Tias yog vim li cas casein kua nplaum yog siv rau hauv cov rooj tog ntau lawm txheej txheem. Nws muaj cov khoom xyaw ntxiv xws li rosin, txiv qaub, thiab tooj liab sulfate. Lawv muab lub peev xwm los siv cov nplaum rau ntau hom ntoo. Los ntawm txoj kev, rooj tog zaum ua nrog casein muab tshuaj txhuam yog suav tias yog ib puag ncig.
