propylene glycol esters siv rau dab tsi?

Nyob rau lub sijhawm thaum kev nyab xeeb khoom noj tseem ceeb heev, cov neeg siv khoom lub hlwb tuaj yeem koom nrog "propylene glycol" yooj yim nrog cov tshuaj, thiab tib lub sijhawm xav tias tsis meej pem: propylene glycol yog dab tsi? Cov zaub mov no puas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv tom qab noj nws?

Propylene Glycol yog dab tsi? Nws puas tuaj yeem siv rau hauv cov khoom noj?

Propanediol suav nrog 1,2-propanediol thiab 1,3-propanediol, ob qho tib si yog cov kua dej tsis muaj xim, yuav luag tsis qab thiab tsis muaj ntxhiab, thiab tsis muaj tshuaj lom thiab ua rau khaus. Propylene glycol yog ib qho tseem ceeb raw khoom rau unsaturated polyester, epoxy resin, polyurethane resin, plasticizer, thiab surfactant.

Cov nyiaj siv rau hauv cov khoom no suav txog li 45% ntawm tag nrho cov nyiaj ntawm propylene glycol, thiab cov polyester tsis muaj saturated yog siv dav hauv kev tsim cov khoom siv tshuaj xws li cov coatings nto thiab cov yas siv zog.

Propylene glycol muaj viscosity zoo thiab hygroscopicity thiab yog dav siv los ua tus neeg sawv cev hygroscopic, antifreeze, lubricant, thiab hnyav hauv cov zaub mov, tshuaj, thiab tshuaj pleev ib ce industries. Hauv kev lag luam khoom noj khoom haus, propylene glycol ester yog lipophilic zaub mov additive, uas tau los ntawm distilling propylene glycol thiab stearate tom qab esterification. Nws yog ntau lub hom phiaj emulsifier.

Hauv kev noj zaub mov,propyleneglycol esters yog siv los ua zaub mov additives, uas muaj xws li stabilizers thiab coagulants, anti-caking agents, defoaming agents, emulsifiers, noo noo retention agents, thiab thickeners.

Txhawm rau ua kom tiav, kev siv propylene glycol esters hauv cov khoom noj muaj qhov zoo hauv qab no: ib qho yog ua kom cov zaub mov saj zoo dua thiab khaws cia rau lub sijhawm ntev; lwm qhov yog ua kom cov dej khaws cia ntawm cov khoom noj thiab txo cov nqi ntawm cov khoom noj khoom haus, xws li nce cov dej ntsiab lus ntawm lub ncuav mog qab zib.

1. tuaj yeem siv rau cov ncuav thiab kib qos yaj ywm chips, qhov siab tshaj plaws yog 2.0g/kg. Rau kev sib xyaw seasoning, qhov siab tshaj plaws yog 20g / kg.

2. Qhov siab tshaj plaws ntawm cov roj, roj, thiab cov khoom siv roj emulsified yog 10.0g/Kg, qhov siab tshaj plaws ntawm cov mis nyuj thiab cov khoom siv mis nyuj, thiab cov dej khov khov yog 5.{{7} }g / Kg, thiab cov khoom sib xyaw yog 20g / kg ntawm ncuav qab zib, cov khoom noj puffed, siav txiv ntseej thiab noob thiab qhov siab tshaj plaws ntawm cov khoom noj txom ncauj yog 2.0g / Kg

3. Nws yog siv los ua emulsifier, defoamer, thiab stabilizer. Raws li emulsifier, HLB tus nqi me me thiab cov kev ua emulsification tsis muaj zog. Nws tsis tshua siv ib leeg.

4. Propylene glycol muaj cov yam ntxwv uas nws muaj lub siab nyiam -crystal daim ntawv, thiab tuaj yeem ruaj khov rau -crystal daim ntawv ntawm lwm cov emulsifiers (xws li monoglycerides) kom cov monoglycerides tuaj yeem tswj lossis ncua daim ntawv -crystal rau -crystal. hom hloov dua siab tshiab, kom nws muaj kev ruaj ntseg zoo emulsion.

5. tuaj yeem siv rau hauv margarine los tiv thaiv kev sib cais dej thiab txaws. Siv rau hauv shortening, nws tuaj yeem tiv thaiv kev laus ntawm qhob cij, pastry, thiab lwm yam, thiab txhim kho nws cov txheej txheem tsim khoom. Siv hauv cov dej khov nab kuab los txhim kho kev nthuav dav thiab cov duab tuav.

6. Nws muaj peev xwm aeration zoo thiab ua kom lub teeb thiab ruaj khov ua npuas ncauj, yog li nws muaj kev lag luam dav hauv cov khoom noj xws li luv luv, cheese bread, thiab ncuav mog qab zib topping cream.

Siv rau cov mis nyuj thiab cov khoom siv mis nyuj (tshwj tsis yog ntau hom koom nrog hauv 01.01.01, 01.01.02, thiab 13.0), roj, roj thiab cov khoom siv roj emulsified, cov dej khov khov (tshwj tsis yog cov dej khov hauv 03.04), cov txiv ntoo siav thiab cov noob (tsuas yog cov txiv ntseej kib), thiab cov noob), cov khoom kib hmoov, khoom qab zib, cov khoom sib xyaw ua ke, cov zaub mov puffed, qhov siab tshaj plaws yog 20g / kg.
