Cov yam ntxwv cuam tshuam rau Xanthan Gum Performance hauv kev ua zaub mov

Xanthan cov pos hniav yog ib qho ntawm cov hydrocolloids txhim khu kev qha tshaj plaws hauv kev ua zaub mov - ua tau zoo ntawm qhov tsis tshua muaj siab (0.1-0.5%), ruaj khov thoob plaws pH dav, thiab tiv taus cua sov thiab shear. Tab sis txhim khu kev qha tsis txhais hais tias tsis siv neeg. Hauv kev xyaum, tib yam khoom xanthan cov pos hniav tuaj yeem xa cov txiaj ntsig sib txawv nyob ntawm seb nws siv li cas.Kev nkag siab txog yam uas cuam tshuam rau nws qhov kev ua tau zoo pab kom tsis txhob muaj teeb meem tshwm sim:lumpy texture, inconsistent viscosity, thiab tsis zoo stability.

 

1. Hydration thiab Dispersion Method

 

Qhov no yog ib qho ua rau xanthan cov pos hniav tsis ua haujlwm hauv kev tsim khoom. Thaum xanthan hmoov ntxiv ncaj qha rau hauv dej yam tsis muaj kev sib xyaw kom zoo, cov khoom hydrate rau sab nraud ua ntej sab hauv, tsim cov pob - qee zaum hu ua "ntses ob lub qhov muag" - uas yuav luag tsis tuaj yeem tawg tom qab.

 

Kev kho yog ncaj nraim:ua ntej- sib tov xanthan nrog rau lwm cov khoom xyaw qhuav (qab zib, ntsev, hmoov txhuv nplej siab) ua ntej ntxiv rau cov kua, tom qab ntawd qhia cov sib tov maj mam nyob rau hauv siab -shear mixing. Qhov no cais cov khoom ua ntej hydration pib thiab xyuas kom meej txawm tias dispersion. Tsis txhob ntxiv xanthan hmoov rau cov dej tseem.

 

2. Cov xwm txheej shear

 

Xanthan gum yog shear-thinning - nws thickens ntawm so thiab thins nyob rau hauv mechanical quab yuam. Cov cuab yeej no muaj txiaj ntsig zoo hauv cov kua ntses thiab hnav khaub ncaws, qhov twg cov khoom yuav tsum tau nchuav yooj yim tab sis tuav nws lub cev ntawm lub phaj lossis hauv pob.

 

 

Hauv kev ua tiav, qib shear yuav tsum ua kom haum rau daim ntawv thov. Tsawg shear thaum sib tov ua rau tsis tiav hydration thiab kev ntxhib los mos tsis sib xws. Ntau dhau heev lawm - tshwj xeeb tshaj yog nyob rau hauv siab - homogenizers ceev khiav rau lub sij hawm ntev - tuaj yeem cuam tshuam viscosity ib ntus.Txoj cai siv tau:siv cov shear txaus los ua kom cov pos hniav kom huv si, tab sis tsis txhob dhau - txheej txheem ib zaug dispersion tiav.

 

3. Qib pH

 

Xanthan cov pos hniavyog ruaj khov nyob rau hauv ib tug dav pH ntau ntawm kwv yees li 2-12, uas ua rau nws haum rau acidic sauces, vinegar-raws li kev hnav khaub ncaws, txiv hmab txiv ntoo haus, thiab pickled khoom - daim ntaub ntawv uas muaj ntau lwm hydrocolloids tawm tsam.

 

Ib qho kev zam:Ntev raug rau pH tsawg heev (hauv qab 3) ua ke nrog cov cua kub siab tuaj yeem maj mam txo cov viscosity dhau sijhawm. Nyob rau hauv ambient- cov khoom lag luam acidic ruaj khov nrog lub neej txee ntev, nws tsim nyog rau kev ruaj ntseg nyob rau hauv qhov chaw cia khoom tiag tiag es tsis yog cia siab rau qhov ntsuas viscosity thawj zaug ib leeg.

 

4. Kub

 

Xanthan cov pos hniav hydrates zoo tshaj plaws ntawm qhov kub nruab nrab - nyob ib ncig ntawm 40-60℃. Cov dej txias dej ua haujlwm tab sis siv sijhawm ntev dua thiab xav tau ntau lub zog sib xyaw. Thaum kub siab (siab tshaj 80℃nyob rau lub sijhawm), qee qhov viscosity poob tuaj yeem tshwm sim, txawm tias xanthan tseem ruaj khov los ntawm cov txheej txheem pasteurization thiab ua noj.

 

Ib daim ntawv qhia:Thaum kawg viscosity feem ntau nce me ntsis ntawm qhov txias. Yog tias koj ntsuas viscosity thaum lub sijhawm ua haujlwm kub thiab kho qhov ntau npaum li cas raws li cov kev nyeem ntawv no, suav rau qhov nce ntxiv - qhov zoo li nyias ntawm 70℃yuav hnyav dua ntawm 20 degree.

 

5. Kev sib tham nrog lwm cov khoom xyaw

 

Ntsev:Cov ntsev nruab nrab feem ntau txhawb viscosity stability. Lub zog ionic siab heev - nyob rau hauv cov khoom salted hnyav heev los yog brines - tuaj yeem txo xanthan lub thickening efficiency. Yog tias koj cov khoom muaj ntsev ntau, sim xanthan kev ua tau zoo hauv cov qauv kawg, tsis yog hauv dej -tsuas yog qhov system.

 

Qab Zib:Qab Zib nce cov tshuaj ntom ntom thiab txhawb kev ruaj ntseg hauv cov dej haus thiab syrups, tab sis nws kuj slows hydration. Nyob rau hauv siab -cov qauv qab zib, ncua sij hawm sib tov lossis nce qhov kub thiab txias me ntsis kom ntseeg tau tias muaj dej txaus.

 

Lwm yam hydrocolloids:Xanthan cov pos hniav ua ke zoo nrog guar cov pos hniav kom muaj zog thickening nyhuv, thiab nrog locust taum cov pos hniav los tsim ib tug mos, cohesive gel qauv. Cov kev sib xyaw ua ke no tau siv dav hauv kev hnav khaub ncaws, khoom noj siv mis, thiab gluten -dawb bakery kom ua tiav cov ntaub ntawv uas tsis yog cov pos hniav muab ib leeg.

 

 

6. Nco ntsoov

 

Hom kev siv theem los ntawm daim ntawv thov:dej qab zib 0.1-0.3%, kua ntses thiab hnav khaub ncaws 0.2-0.5%, bakery filling mus txog 0.5%. Tshaj qhov ntau yam no tsis txhim kho kev ua tau zoo - nws feem ntau ua rau cov tuab tuab, stringy, lossis slimy zoo nkauj uas cuam tshuam rau qhov ncauj.

 

Pib ntawm qhov qis kawg ntawm qhov kev pom zoo ntau thiab nce me me increments. Kev sim hauv cov khoom tiag tiag, tsis yog hauv dej xwb, vim tias lwm cov khoom xyaw cuam tshuam rau qhov kawg viscosity.

 

7. Cia thiab tuav

 

Xanthan cov pos hniav absorbs ya raws yooj yim. Kev cuam tshuam rau cov av noo ua rau clumping thiab txo cov flowability, uas cuam tshuam rau qhov tseeb ntawm kev txhaj tshuaj ntawm cov kab ntau lawm. Khaws rau hauv qhov chaw txias, qhuav, zoo- qhov cua qhov chaw, khaws cov ntim kom nruj tom qab qhib, thiab tsis txhob tso lub hnab ncaj qha rau hauv cov plag tsev txias uas muaj qhov sib xyaw ua ke.
