Propylene Glycol, Ib qho Khoom Noj Ntxiv Uas Tsis ntev los no tau poob rau hauv kev hnoos qeev ntawm Kev voj voog

Propylene glycol yuav tsum tsis muaj kev sib raug zoo nrog cov phooj ywg hauv kev lag luam ntxiv, tab sis propylene glycol nkag mus rau kev lag luam khoom noj khoom haus ua khoom noj ntxiv rau xyoo 2012, yog li ntau tus phooj ywg hauv kev lag luam ci tsis tau paub' t paub ntau txog nws. Yog li dab tsi yog propylene glycol? Qhov tseeb, propylene glycol yog khoom noj khoom noj khoom haus ntxiv npaj los ntawm hydration ncaj qha nrog propylene oxide thiab dej ua raw khoom.

Nrog kev txhim kho ntawm cov zaub mov noj cov cai thiab cov cai thiab kev ntxiv dag zog rau kev saib xyuas, ntau thiab ntau dua cov khoom noj khoom haus muaj nyob rau hauv cov kev ntsuas uas yuav tsum tau kuaj xyuas, xws li cov khoom siv tshuaj ua kom zoo li qub sodium sodium dehydroacetate, potassium sorbate, calcium propionate, tshuaj ua kom muaj tshuaj sodium Tammycin, thiab lwm yam. , tam sim no tseem suav nrog propylene glycol. Tom qab ntawv tus kws kho hloov ntawm Baiqing yuav qhia koj yuav ua li cas siv propylene glycol hauv kev ntsuas kom tsis txhob dhau tus txheej txheem.

Koj tuaj yeem pom los ntawm cov lus saum toj no:

1. Propylene glycol raws li cov khoom noj khoom haus muaj peev xwm tsuas yog siv rau hauv cov khoom qab zib hauv cov khoom lag luam bakery, xws li cov khoom qab zib, ncuav thiab lwm yam khoom uas yog pawg ntawm cov khoom qab zib, thiab qhov siv ntau tshaj plaws yuav tsum tsis pub ntau tshaj peb txhiab.

2. Nws yog kev tsis pom ntxiv mus ntxiv qee yam tsw qab hauv kev tsim cov khoom. Feem ntau, propylene glycol siv los ua cov kuab tshuaj thiab cov cab kuj hauv cov kua tsw, yog li dab tsi yuav tsum tau them sai sai rau?

① Hais txog qhov sib ntxiv thiab siv, sim ua kom tsis txhob ntxiv cov khoom noj tsis qab xws li mov ci. Txawm hais tias qhov no ua tau raws li lub hauv paus ntsiab lus ntawm kev nqa tuaj, cov khoom noj zaub mov tsuas yog tuaj yeem ua cov khoom noj uas muaj qab nyob hauv daim ntawv zaub mov, thiab cov khoom xyaw hauv cov khoom tsis tuaj yeem tsis pom, yog li thaum kuaj pom thaum siv propylene glycol, nws tsis tuaj yeem thov rov hais dua Cov. (Qhov no yog qhov xwm txheej tam sim no, saib seb puas muaj cov cai ntsig txog yuav tau hloov kho yav tom ntej)

Thaum siv rau hauv cov khoom qab zib, xyuam xim rau tag nrho cov nyiaj ntawm propylene glycol ntxiv rau tus nqi ntawm cov kua tsw qab, txawm hais tias yuav muaj cov khoom qab zib poob, tab sis qhov kub taw tes ntawm propylene glycol yog 188.2 ℃, cov tub ntxhais kub ntawm cov khoom yog deb ntawm kev ncav cuag, yog li ntawd lub ncuav ploj ntawm propylene glycol Nws tsis loj npaum li dej haus, yog li yuav tsum ceev faj thaum siv nws.

3. Propylene glycol tseem muaj nyob hauv qee qhov ntxiv emulsifying, xws li cov roj ncuav mog qab zib, mov ci emulsifier, thiab lwm yam Yog li ntawd, hauv kev xaiv ntawm cov tshuaj emulsifiers, siv emulsifiers uas tsis muaj propylene glycol ntau li ntau tau kom tsis txhob siv kev ua txhaum cai.
