Dab tsi yog Distilled Monoglycerides?
Distilled Monoglycerides (DMG), tshuaj hu ua Glyceryl Monostearate (GMS), muaj cov mis mos molecular C₂₁H₄₂O₄ thiab CAS naj npawb 123-94-4. Lawv tau tsim los ntawm cov roj zaub (xws li cov roj txiv roj, cov roj taum pauv, thiab cov roj rapeseed) los ntawm kev hloov pauv mus rau kev sib xyaw monoglyceride, tom qab ntawd los ntawm kev ua kom huv si.molecular distillation technology.
Cov khoom lag luam monoglyceride feem ntau tsuas muaj 40% -60% cov ntsiab lus nquag monoester. Tom qab molecular distillation purification, cov ntsiab lus monoester tuaj yeem ncav cuagtshaj 90%, nrog qee cov khoom lag luam hwm tau ua tiav 95% -99%. Qhov no purity siab tsub kom emulsifying muaj peev xwm los ntawm 3-4 lub sij hawm piv rau zoo tib yam crude esters.
Kev txheeb xyuas qhov tseem ceeb:
- Cov tsos mob: Dawb hmoov los yog me me cylindrical khoom, tsw tsw
- HLB Value: 3.9-5.3 (lipophilic non-ionic emulsifier)
- Solubility: Insoluble hauv dej txias; dispersible nyob rau hauv cov dej kub kom ruaj khov hydrated dispersions; soluble nyob rau hauv cov roj kub
- Kev nyab xeeb: FDA GRAS xwm txheej; ADI tsis txwv
Core Functions ntawm Distilled Monoglycerides
1. Starch Anti-Staling – Qhov tseem ceeb tshaj plaws muaj nuj nqi
Lub luag haujlwm tseem ceeb ntawm distilled monoglycerides yog tsimcomplexesnrog starch molecules los tiv thaiv retrogradation (staling). Lawv cov qauv linear molecular tso cai rau lawv nkag mus rau hauv lub helix ntawm gelatinized amylose, tsim kom ruaj khov insoluble complexes. Thaum cov txheej txheem no tsim, cov hmoov txhuv nplej siab tuaj yeem tsis tuaj yeem rov ua dua tshiab, cia cov khob cij, pastries, thiab lwm yam khoom ci kom nyob twj ywm tshiab thiab muag rau lub sijhawm ntev.
2. Gluten Strengthening - Txhim kho cov qauv ua khob noom cookie
Distilled monoglycerides cuam tshuam nrog gluten proteins, txhawb kev nthuav dav thiab ruaj khov ntawm gluten network. Qhov no muab lub khob noom cookie zoo dua elasticity thiab extensibility, cia nws zoo khaws roj thaum lub sij hawm fermentation.
3. Emulsification thiab Dispersion - Blending Roj thiab dej
Raws li tsis yog -ionic emulsifiers, distilled monoglycerides txo cov roj-dej interfacial nro, cia cov rog sib cais nyob rau hauv lub cev thiab tiv thaiv roj- dej sib cais.
4. Foam Stabilization - nce ntim
Distilled monoglycerides ruaj khov ua npuas los ntawm kev tsim -gel theem, ua rau lub ntim loj dua thiab zoo nkauj zoo nkauj hauv ncuav mog qab zib, ice cream, thiab lwm yam khoom. Kev tshawb fawb qhia tau hais tias ntxiv distilled monoglycerides ho txhim kho lub khob noom cookie aeration.
5. Kev hloov kho siv lead ua - Tswj cov rog crystallization
Distilled monoglycerides tswj cov roj crystallization tus cwj pwm, inhibiting kev hloov ntawm ' mus rau polymorphic cov ntaub ntawv, tiv thaiv "graininess" (sanding) nyob rau hauv margarine, shortening, thiab lwm yam khoom.
Lub luag haujlwm tseem ceeb hauv Kev Lag Luam Baking
Distilled monoglycerides yog cov emulsifiers siv dav tshaj plaws hauv kev lag luam ci, suav txog ntau dua ib nrab ntawm tag nrho cov khoom lag luam emulsifier. Lawv txoj haujlwm tseem ceeb tshwm sim los ntawm lub luag haujlwm tsis tuaj yeem hloov pauv thoob plaws ntau yam tseem ceeb.
| Daim ntawv thov cheeb tsam | Muaj nuj nqi tshwj xeeb | Pom zoo noj | nyhuv |
|---|---|---|---|
| Zaub mov | Cov hmoov nplej ntxiv dag zog, tiv thaiv -staling | 0.3% - 0.8% ntawm hmoov | Nce ntim, txhim kho crumb qauv, ncua lub neej txee |
| Ncuav mog qab zib | Aeration, ua npuas ncauj stabilization | 3% -10% yog ' | Qhov ntau ntxiv ntim, nplua thiab zoo npuas npuas, ilv kev ntxhib los mos |
| Biscuits | Fat dispersion, tiv thaiv - los ntshav | 1.5% -2% yog ' | Nce crispiness, yooj yim demolding, meej impressions |
| Instant Noodles | Txhim kho kev ua haujlwm, txo cov roj nqus | 0.1% - 0.2% ntawm hmoov | Txo ua noj poob, txhim khu elasticity |
| Cov khoom siv hmoov nplej | Kev txhim kho kev ntxhib los mos | Raws li xav tau | Tiv thaiv cov kua zaub cloudiness, nce elasticity |
| Frozen ncuav mog qab zib | Txias -thaw stability | Raws li xav tau | Tiv thaiv gluten network, tuav pov thawj muaj peev xwm |
Synergistic Effects nrog lwm cov emulsifiers:
Distilled monoglycerides feem ntau siv ua ke nrog lwm cov emulsifiers rau kev sib koom ua ke:
- Nrog SSL: Ib txhij ntxiv dag zog gluten thiab qeeb staling hauv qhob cij
- Nrog DATEM: Ua kom ntim thaum tuav lub softness
- Nrog Sucrose Esters / Polysorbates: Ua raws li ncuav mog qab zib aerating tus neeg sawv cev, tsim "protein-monoglyceride" complexes
Txoj kev siv
Distilled monoglycerides tuaj yeem siv ntau txoj hauv kev nyob ntawm cov khoom lag luam:
- Hydration Dispersion Method: Ntxiv 1 feem monoglycerides rau 20-30 qhov dej, kub rau 65-75℃nrog nplawm kom yaj, ua kom zoo li hydrate. Qhov no nce HLB tus nqi rau 9-10. Haum rau cov khoom qab zib khov, dej haus, ncuav mog qab zib roj, noodles, sausages, thiab lwm yam khoom uas muaj roj tsawg.
- Roj Dissolution Txoj Kev: Dissolve ua ke nrog roj / rog los ntawm cua sov (Ntau dua lossis sib npaug li 60 degree) ua ntej siv. Haum rau biscuits, ncuav mog qab zib, ncuav pastries, nqaij cov khoom, thiab lwm yam khoom siab - rog.
- Txoj Kev Qhuav Qhuav: Sib tov ncaj qha nrog lwm cov khoom xyaw qhuav; lub emulsifier dissolves thaum dej kub ntxiv thaum ua. Haum rau pastry hmoov, dumpling hmoov, thiab hmoov txhim kho.
Cia: Khaws ntim rau hauv qhov chaw txias, qhuav. Lub neej txee yog 24 lub hlis.
Xaus
Distilled monoglycerides tau dhau los ua "cov pob txha" ntawm kev lag luam ci vim lawv cov qauv molecular tshwj xeeb thiab cov purity siab ua tiav los ntawm distillation. Lawv ncua kev staling los ntawm complexing nrog hmoov txhuv nplej siab, ntxiv dag zog rau mov paj los ntawm interacting nrog gluten, thiab nce ntim los ntawm stabilizing ua npuas ncauj-qhov no "peb-nyob rau hauv-ib" versatility ua rau lawv tseem ceeb nyob rau hauv ib tug ntau yam ntawm daim ntawv thov xws li mov ci, ncuav mog qab zib, biscuits, thiab hmoov-raws li cov khoom.
Raws li kev pom zoo kev lag luam hais tias:"Yog tsis muaj monoglycerides, yuav tsis muaj kev lag luam ci niaj hnub no."Distilled monoglycerides tsis yog tsuas yog siv ntau tshaj plaws emulsifier tab sis kuj yog ib qho tseem ceeb ntawm kev txiav txim siab ntawm cov khoom ci zoo.
