CAS Nr .: 9000-71-9
Casein CAS 9000-71-9 yog non-crystalline, tsis-hygroscopic tshuaj. Nws tuaj yeem yaj 0.8-1.2% hauv dej ntawm chav tsev kub, me ntsis soluble hauv 25 ℃ dej thiab cov kuab tshuaj organic, soluble hauv dilute alkali thiab concentrated acid, tuaj yeem nqus dej, thiab nthuav dav sai thaum muab tso rau hauv dej, tab sis yoov tshaj cum tsis khi. Nws tsis muaj ntxhiab, tsis qab los yog muaj me ntsis aroma thiab saj. Nws yog insoluble hauv dej thiab cawv. Nws dissolves nyob rau hauv alkali tov los tsim caseinate. Lub isoelectric point yog pH 4.6.

1. Thickener; emulsifier; stabilizer; khoom noj khoom haus ntxiv (fortified protein); daim ntawv; muab tub lim; tus cab kuj. Nws yog tshwj xeeb tshaj yog haum rau cheese thiab ice cream, nrog rau ntau npaum li cas ntawm 0.3% mus rau 0.7%, nqaij cov khoom (ham, hnyuv ntxwm) 1% mus rau 3% thiab dej minced nqaij cov khoom. Txhim kho cov protein ntawm qhob cij thiab biscuits 5%; mayonnaise 3%.
2. Casein CAS 9000-71-9 feem ntau yog siv los ua cov khoom siv hauv cov txheej txheem, cov nplaum rau cov ntoo, ntawv thiab ntaub, thiab cov khoom siv ntxiv. Raws li cov khoom siv rau txheej txheej, nws suav txog ib nrab ntawm tag nrho cov khoom siv. Nws muaj kev tiv thaiv dej zoo heev thiab tuaj yeem tawg tau zoo hauv cov xim los txhim kho qhov sib xws ntawm cov txheej txheem. Tsis tas li ntawd, vim nws zoo fluidity thiab yooj yim txheej siv, crude rennet protein feem ntau yog siv los ua cov nyees khawm yas. Piv nrog rau lwm cov nyees khawm, casein nyees khawm muaj dyeability zoo, processability, thiab xim brightness, thiab lawv qhov zoo yog nyob rau hauv nruab nrab thiab sab sauv qib ntawm cov nyees khawm. Casein sib tov sib xyaw nrog slaked txiv qaub, sodium fluoride, thiab tooj liab sulfate, thiab tom qab ntawd ntxiv nrog kerosene kom tau cov kua nplaum casein, uas yog ib hom nplaum siv hauv kev lag luam aviation thiab kev ua haujlwm ntoo. Casein kuj tseem siv hauv tshuaj thiab biochemical reagents.
3.Casein CAS 9000-71-9 yog hygroscopic thiab yog siv los ua cov kua nplaum ntoo, ntawv txheej, cov khoom noj ntshav qab zib, cov khoom siv roj ntsha, textile pulp, thiab lwm yam.
