Dab tsi yog stearic acid hmoov?
Stearic acid hmoovyog dawb los yog daj ntseg daj cov khoom thiab yog ib qho ntawm lub ntsiab ntev fatty acids uas ua rau cov rog thiab roj. Nws muaj nyob rau hauv daim ntawv ntawm glycerides hauv tsiaj rog, roj, thiab qee cov roj zaub, uas yog hydrolyzed kom tau cov kua qaub. Stearic acid yog ib tug dav tam sim no fatty acid nyob rau hauv xwm, nrog tshuaj zoo ib yam li cov carboxylic acids. Yuav luag txhua cov roj thiab cov rog muaj cov nyiaj sib txawv ntawm cov kua qaub ua rau cov kua qaub. Nws cov ntsiab lus tseem ceeb hauv cov tsiaj rog, xws li butter, uas tuaj yeem ncav cuag mus txog 24%, thiab tsawg dua cov roj tshuaj yej ntawm 0.8% thiab xibtes roj ntawm 6%. Txawm li cas los xij, cov ntsiab lus hauv Cocoa Butter yog qhov siab li 34%.

Dab tsi yog qhov tseem ceeb siv ntawm stearic acid hmoov?
|
|
Stearic acid hmoov yog dav siv nyob rau hauv cov tshuaj pleev ib ce, cov tshuaj tua hluav taws, cov pa roj hmab, cov tshuaj tua hluav taws xob, cov khoom siv roj hmab, tshuaj ntsuab, thiab lwm yam khoom siv organic. Stearic acid kuj tseem siv tau los ua cov kuab tshuaj rau cov roj pleev roj, cov tshuaj pleev ib ce rau cov ntawv ciab, thiab emulsifier rau cov kua qaub glycerides. Stearic acid hmoov yog dav siv nyob rau hauv kev tsim khoom ntawm polyvinyl chloride yas roj, ntawv, profiles, thiab yeeb yaj kiab. Nws yog cov cua sov stabilizer rau polyvinyl chloride, nrog lubricity zoo thiab lub teeb zoo thiab kub ruaj khov. Hauv daim ntawv thov ntawm polyvinyl chloride kav, stearic acid pab tiv thaiv "COKING" thaum ua. Stearic acid tuaj yeem txhim kho qhov ua kom muaj cov nyhuv ntawm inorganic hmoov txheej thiab nce cov khoom siv hluav taws xob, Monomic lossis Polyol esters ntawm stearic acid tuaj yeem siv los ua tshuaj pleev ib ce, cov tshuab yas, thiab lwm yam alkali hlau ntsev yaj hauv dej thiab yog ib qho ntawm cov khoom siv tseem ceeb ntawm xab npum. Lwm cov khoom siv hlau tuaj yeem siv los ua cov tshuaj tiv thaiv dej, cov roj nplua nyeem, tshuaj tua kab mob, txheej ntxiv tshuaj sib ntxiv, thiab polyvinyl chloride stabilizers. |

Npaum li cas yog metabolism ntawm stearic acid hmoov hauv tib neeg lub cev?
Ib qho kev kawm cim npe isotope kev kawm tau xaus tias kev ua zaub mov noj kua qaub yog 2.4 npaug siab dua li cov acid analogously hloov mus rau palmitoleic acid. Tsis tas li ntawd, stearic acid tsawg dua yuav tau koom rau hauv cov roj (cholesterol. Hauv epidemiologic thiab cov kev tshawb nrhiav soj ntsuam, cov kua qaub ua rau muaj kev cuam tshuam nrog cov roj (qis dua cov roj

Yuav ua li cas thiaj ua rau staric acid hmoov?
 |
Stearic acid hmoovtuaj yeem ua los ntawm cov pej xeem roj lossis CPO nrog ob txheej txheem. Ua ntej yog hydrolysis ntawm xibtes roj tsis muaj catalalys nrog siab 45atm hauv qhov kub 250 degree. Splitting hloov dua siab sis txhais tau tias cov roj (triglyceride) tuaj yeem ncav cuag qhov siab tshaj 98%. Nyob rau hauv no hydrolysis cov tshuaj tiv thaiv ntawm Palm roj yuav tsim myristic acid, palromicic acid, linoleic acid, oleic acid, stearic acid, stearic acid thiab glyserol. Qhov feem pua ntawm stearic acid tsuas yog li ntawm 5% los ntawm cov roj acid uas tsim, oleic acid 41% thiab linoleic acid 10%. Txog kev tau txais kev lag luam stearic acid hmoov, oleic acid thiab linoleic acid yuav tsum yog hydrogenated. Qhov thib ob yog hydrogenation cov tshuaj tiv thaiv ntawm oleicic acid thiab cov ntaub acid acid thiab kub tau siv los ua catalyst, hloov dua siab hydrogenation tiv thaiv yog li 99%
