Qhov sib txawv tseem ceeb ntawm sodium propionate thiab calcium propionate yog tias sodium propionate muaj sodium cation khi rau propionate anion, hos calcium propionate muaj calcium cation khi rau ob propionate anions.
Sodium propionate thiab calcium propionate yog ionic compounds uas muaj cation thiab anion. Cov tebchaw no yog ob hom ntsev sib txawv ntawm propionic acid. Qhov tseem ceeb tshaj, ob qho tib si cov ntsiab lus tseem ceeb xws li zaub mov preservatives.
Sodium Propionate yog dab tsi?
Sodium propionate lossis sodium propanoate yog sodium ntsev ntawm propionic acid. Cov tshuaj formula ntawm no compound yog Na(C2H5COO). Nws tshwm sim raws li cov dawb crystalline khoom uas yog deliquescent thaum raug rau cov huab cua ntub. Cov molar mass ntawm no compound yog 96 g / mol. Nws zoo nkaus li pob tshab crystals. Tsis tas li ntawd, cov tshuaj no muaj cov ntxhiab tsw acetic-butyric.
Thaum xav txog kev tsim cov sodium propionate, peb tuaj yeem tsim nws los ntawm cov tshuaj tiv thaiv ntawm propionic acid thiab sodium carbonate. Raws li lwm txoj hauv kev, peb tuaj yeem siv sodium hydroxide tsis yog sodium carbonate.
Muaj qee qhov kev siv sodium propionate - nws daim ntawv thov loj yog ua zaub mov noj. Cov ntawv sau npe ntawm cov khoom noj rau qhov sib xyaw no yog E 281. Hauv cov khoom bakery, cov tshuaj no tsuas yog siv rau pwm inhibiting. Nws yog cov khoom noj uas tau pom zoo nyob hauv ntau lub tebchaws hauv ntiaj teb.
Calcium Propionate yog dab tsi?
Calcium propionate lossis calcium propanoate yog calcium ntsev ntawm propionic acid. Cov tshuaj formula ntawm no compound yog Ca(C2H5COO)2 Nws tshwm li dawb crystalline khoom, thiab molar mass ntawm no compound yog 186 g / mol. Calcium propionate yog me ntsis soluble hauv dej thiab cawv xws li methanol thiab ethanol. Ntxiv mus, cov tshuaj no yog insoluble nyob rau hauv acetone thiab benzene. Cov qauv siv lead ua ntawm cov tshuaj no yog monoclinic.
Muaj ntau ntau siv calcium propionate. Nws yog tsuas yog siv los ua zaub mov additive. Peb tuaj yeem sau nws li E 282. Tsis tas li ntawd, nws yog ib qho khoom noj khoom haus tseem ceeb. Nws muaj txiaj ntsig zoo li cov khoom noj ntxiv hauv cov qhob cij, cov khoom ci ci, cov nqaij ua tiav, whey, thiab feem ntau ntawm cov khoom siv mis nyuj. Tsis tas li ntawd, cov tshuaj no tseem ceeb hauv kev ua liaj ua teb los tiv thaiv cov mis nyuj kub hauv nyuj, ua zaub mov ntxiv, thiab lwm yam.
Dab tsi yog qhov zoo sib xws ntawm Sodium Propionate thiab Calcium Propionate?
- Sodium propionate thiab calcium propionate yog ob ntsev ntawm propionic acid.
- Ob lub tebchaw no tseem ceeb ua zaub mov noj.
Qhov txawv ntawm Sodium Propionate thiab Calcium Propionate yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sodium propionate thiab calcium propionate yog tias sodium propionate muaj sodium cation khi rau propionate anion, thaum calcium propionate muaj calcium cation khi rau ob propionate anions. Cov tshuaj formula ntawm sodium propionate yog Na(C2H5COO), whereas cov tshuaj formula ntawm calcium propionate yog Ca(C 2H5COO)2
Ntxiv mus, sodium propionate tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm propionic acid thiab sodium carbonate thaum calcium propionate yog tsim los ntawm cov tshuaj tiv thaiv ntawm propionic acid thiab calcium carbonate. Thaum xav txog kev siv sodium propionate, nws yog ib qho tseem ceeb raws li cov khoom noj preservative, zaub mov additive, tseem ceeb hauv cov khoom bakery, tshwj xeeb tshaj yog rau pwm inhibiting. Calcium propionate muaj txiaj ntsig zoo li cov khoom noj ntxiv hauv cov qhob cij, cov khoom ci ci, cov nqaij ua tiav, whey, thiab cov khoom siv mis nyuj feem ntau.
Hauv qab infographic qhia txog qhov sib txawv ntawm sodium propionate thiab calcium propionate.
Summary – Sodium Propionate vs Calcium Propionate
Sodium propionate thiab calcium propionate yog ob hom ntsev sib txawv ntawm propionic acid. Qhov sib txawv tseem ceeb ntawm sodium propionate thiab calcium propionate yog tias sodium propionate muaj sodium cation khi rau propionate anion thaum calcium propionate muaj calcium cation khi rau ob propionate anions.
