Calcium stearate yog siv los ua emulsifier hauv cov khoom noj, tshuaj pleev ib ce thiab tshuaj lag luam. Cov tshuaj no yog hu ua additive E572. Cov tshuaj no muaj kev nyab xeeb npaum li cas rau tib neeg kev noj qab haus huv? Thiab nws cuam tshuam rau lub cev li cas? Peb yuav xav txog cov teeb meem no hauv kab lus.
Kev piav qhia
Koj tuaj yeem pom cov lus hais ntawm lub ntim uas cov khoom muaj calcium stearate. Nws yog dab tsi? Cov tshuaj no yog calcium ntsev ntawm stearic acid. Nws cov tshuaj formula yog CaC36H70O4.
Cov tshuaj no tseem hu ua calcium stearate. Nws tau txais los ntawm cov tshuaj tiv thaiv tshuaj, qhov twg calcium oxide thiab stearic acid yog siv los ua reagents. Tsis tas li ntawd, cov tshuaj no yog tsim thaum xab npum reacts nrog dej nyuaj.
Calcium stearate yog cov hmoov dawb. Nws muaj soapy kev ntxhib los mos. Ntxiv E572 tsis tuaj yeem yaj hauv dej thiab ethyl cawv. Nws melts ntawm +88 degrees thiab yog heev flammable.
Properties
Vim li cas calcium stearate siv dav hauv kev lag luam? Qhov kev sib txuas no yog siv raws li:
- Emulsifier. Additive E572 pab ua ke cov tshuaj uas nyuaj rau kev sib xyaw ua ke hauv ib txwm muaj. Nrog nws, koj tuaj yeem tau txais, piv txwv li, sib tov ntawm cov roj tov thiab dej.
- Thickener. Calcium stearate ua rau cov khoom sib xyaw kom khov.
- Shaper. Additive E572 tuav cov duab, qauv thiab sib xws ntawm qhov sib tov.
Daim ntawv thov
Cov kev lag luam twg siv calcium stearate? Feem ntau, cov tshuaj no yog siv nyob rau hauv kev tsim cov tshuaj pleev ib ce: qhov muag ntxoov ntxoo, blush, hmoov, tshuaj zawv plaub hau thiab plaub hau balms. Cov additive ua rau kom qhov ntim ntawm qhov sib tov, thiab tseem tiv thaiv cov khoom los ntawm kev sib txuas ua ke thiab cov tsos ntawm lumps.
Ntxiv E572 kuj tseem siv rau hauv kev tsim tshuaj. Cov tshuaj no muaj nyob rau hauv ib co tshuaj.
Ntxiv rau, calcium stearate yog siv los ua kom ruaj khov thiab roj nplua nyeem rau cov yas. Cov tshuaj no ntxiv rau cov kua roj vanish thiab xim kom lawv qhuav sai dua thaum siv.
Calcium stearate qee zaum siv los ua cov thickener rau lubricants. Txawm li cas los xij, nws txoj kev siv tsuas yog txwv vim nws qhov hluav taws kub nce ntxiv.
Puas yog cov tshuaj ntxiv E572 siv hauv kev tsim khoom noj? Hauv tebchaws Russia thiab ntau lub tebchaws, kev siv cov tshuaj no ua cov thickener rau zaub mov raug txwv. Txawm li cas los xij, stearatecalcium yog ib feem ntawm cov khoom noj ntxiv E470. Nws yog tsim nyob rau hauv lub npe "Fatty acids, ntsev ntawm txhuas thiab calcium." Cov tshuaj no muaj nyob rau hauv instant soups, hmoov qab zib thiab qabzib hmoov.
Nyob zoo rau lub cev
Puas yog calcium stearate ua mob rau lub cev? Yuav kom nkag siab txog qhov teeb meem no, koj yuav tsum xav txog cov txiaj ntsig ntawm cov tshuaj ntxiv. Calcium stearate, thaum nws nkag mus rau hauv lub plab zom mov, reacts nrog kua txiv hmab txiv ntoo. Raws li kev cuam tshuam ntawm hydrochloric acid, cov tshuaj sai sai decomposes rau hauv stearic acid thiab calcium sulfate. Nyob rau hauv nws daim ntawv ntshiab, stearate yog absorbed nyob rau hauv lub cev nyob rau hauv ntau me me.
Tsuas yog ib qho loj heev ntawm cov khoom tuaj yeem ua rau raug mob. Nws raug tso cai haus tsis pub ntau tshaj 2.5 g ntawm cov tshuaj ntxiv rau 1 kg ntawm lub cev hnyav ib hnub. Yog tias qhov koob tshuaj no ntau dhau lawm, cov thyroid tsis ua haujlwm yuav tshwm sim. Yog tias koj tsis tsim txom cov khoom nrog ntxiv ntawm E470, ces yuav tsis muaj teebmeem kev noj qab haus huv.
Nws tseem ceeb heev uas yuav tsum tau xyuam xim rau kev sib raug zoo ntawm calcium stearate nrog rau lwm yam tshuaj. Cov tshuaj ntxiv no tuaj yeem tsim teeb meem thaum noj nrog cawv. Tsis tas li ntawd, cov khoom uas muaj E470 yuav tsum tsis txhob muab ntxuav nrog lub zog haus.
Nyob rau hauv cov ntaub ntawv ntawm metabolic ntshawv siab, zaub mov nrog ntxiv ntawm E470 yuav tsum raug tshem tawm tag nrho ntawm cov khoom noj. Yog tias ib tus neeg cov metabolism tsis ua haujlwm zoo, ces calcium stearate tuaj yeem ua rau cov kab mob hauv plab.
Nws tuaj yeem xaus lus tias rau cov neeg noj qab haus huv, stearate tsis muaj teeb meem yog tias koj siv cov tshuaj ntxiv no hauvtso cai kom muaj nuj nqis.
