Yuav ua li cas Pectin E440 daws kev ntxhib los mos ntawm qhov qis - Qab Zib Jams

Txo cov suab thaj hauv jam yuav zoo li yooj yim, tab sis qhov tseeb, nws tuaj yeem nyuaj heev. Qab zib tsis yog rau qab zib xwb - nws kuj tseem pab tsim cov gel, khi dej, thiab ua kom qhov kev ntxhib los mos ruaj khov. Thaum cov piam thaj txo qis, jams feem ntau ua kua dej, cais thaum khaws cia, lossis poob lawv qhov sib xws, sib kis tau zoo.

 

Pectin E440 pab daws cov teeb meem no. Nws rov tsim cov qauv uas muaj suab thaj ib txwm muab. Kab lus no piav qhia vim li cas qis - qab zib jams feem ntau ua tsis tiav hauv kev ntxhib los mos, pectin txhim kho kev ruaj ntseg, thiab dab tsi los tsom rau hauv kev tsim.

 

Vim Li Cas Txo Qab Zib Destabilizes Jam Texture

 

Tsoos jam ua haujlwm vim muaj peb txoj kev sib cuam tshuam ntawm pectin, qab zib, thiab kua qaub.Qab Zib muaj ob txoj haujlwm tseem ceeb tshaj qhov qab zib:nws pab qhib lub pectin gel network, thiab nws khi cov dej dawb, txo cov dej ua haujlwm thiab ua kom cov jam hauv cov qauv tsis zoo.

 

Thaum cov piam thaj txo qis dua li ntawm 55-60% soluble solids, ob yam tshwm sim ib txhij. Ua ntej, cov gel network tsis muaj zog lossis tsis ua tiav tag nrho, vim tias tus qauv siab -methoxyl pectin yuav tsum muaj cov piam thaj ntau dhau los hla - txuas. Qhov thib ob, cov dej tsis sib haum txav mus los ntawm cov khoom, ua rau muaj kev sib koom ua ke - cov dej sib cais uas ua rau qis - qab zib jam zoo li tsis ruaj khov ntawm lub txee.

 

 

Tsuas yog ntxiv ntau tus qauv pectin tsis kho qhov no. Lub tshuab gel tsis raug rau qhov qis - qab zib ib puag ncig.

 

Pectin E440 yog dab tsi thiab vim li cas hom teeb meem

 

Pectin (E440)yog lub ntuj polysaccharide muab rho tawm los ntawm citrus tev lossis kua pomace. Nws tau pom zoo ua tus neeg sawv cev gelling, stabilizer, thiab thickener thoob plaws EU, Asmeskas, thiab thoob ntiaj teb kev lag luam feem ntau, thiab tau siv dav hauv kev huv huv - daim ntawv lo vim nws lub hauv paus chiv keeb.

 

Muaj ob hom loj,thiab xaiv qhov tsis ncaj ncees lawm yog qhov feem ntau yog vim li cas qis - qab zib jam formulations poob:

 

High Methoxyl (HM) Pectin gels los ntawm hydrogen bonding thiab xav tau ob qho tib si qab zib concentration (feem ntau siab dua 55%) thiab pH qis (3.0-3.5). Nws yog tus qauv kev xaiv rau ib txwm muaj - qab zib jam. Hauv qhov qis - qab zib, nws tsuas yog tsis gels - lossis gels tsis muaj zog thiab tsis sib xws.

 

Tsawg Methoxyl (LM) Pectin gels los ntawm calcium cross- txuas ntau dua li qab zib concentration. Nws tuaj yeem tsim cov gel ruaj khov ntawm cov suab thaj hauv qab 55%, ua rau nws yog qhov kev xaiv raug rau txo - qab zib thiab tsis muaj - ntxiv- qab zib jam formulations. Lub zog gel yog tswj los ntawm cov ntsiab lus calcium thiab pH ntau dua li qib qab zib.

 

Rau qis - qab zib jams, LM pectin tsis yog lwm txoj hauv kev - nws yog tib txoj kev xaiv.

 

 

Yuav ua li cas LM Pectin Rebuilds Texture nyob rau hauv qis - Qab Zib Jams

 

Gel tsim tsis muaj suab thaj ntau.LM pectin tsim ib qho peb -sib nqus gel network los ntawm calcium txuas ntawm pectin chains. Lub network no muab kev ruaj khov thiab lub cev uas cov piam thaj ib txwm ua rau, tsis muaj cov ntsiab lus soluble. Ib qho dej -formulated qis- qab zib jam nrog LM pectin tuaj yeem ua tiav tib yam kev ncaj ncees raws li ib txwm jam ntawm ib feem ntawm cov suab thaj.

 

Kev sib koom ua ke ntawm dej thiab tswj kev sib koom ua ke.Lub gel network tsim los ntawm LM pectin lub cev ntxiab dej dawb, tiv thaiv nws los ntawm kev tsiv mus rau saum npoo los yog pas dej hauv qab ntawm lub hub. Qhov no yog kev kho ncaj qha rau cov teeb meem dej ntxhia uas cuam tshuam rau feem ntau qis - qab zib jam hloov kho yam tsis muaj kev hloov kho pectin.

 

Spreadability tswj.LM pectin tso cai rau kev kho kom zoo ntawm viscosity los ntawm ntau npaum thiab calcium. Ntawm 0.5-0.8% pectin nrog cov calcium uas tsim nyog, qhov tshwm sim yog ib qho smooth, kis tau zoo nkauj - tsis dhau nruj, tsis dhau dej. Nce pectin rau 1.0-1.2% nyob rau hauv firmer formulations (xws li txiv hmab txiv ntoo filling rau bakery) muab ib tug ntau txheej kev ntxhib los mos uas tuav zoo thaum lub sij hawm ua.

 

Ntsiab Formulation Parameters

 

Tau txais LM pectin ua kom raug yuav tsum tau saib xyuas peb qhov sib txawv:

 

pH.Qhov zoo tshaj plaws rau LM pectin gelling yog pH 3.0-3.5. Sab nraum qhov no - tshwj xeeb tshaj yog saum toj no 3.8 - gel lub zog txo qis. Hauv cov txiv hmab txiv ntoo jams uas ntuj acidity txawv, pH hloov nrog citric acid feem ntau tsim nyog los xyuas kom meej qhov sib xws.

 

Calcium qib.LM pectin gels los ntawm calcium cross-txuas, yog li calcium yuav tsum muaj nyob rau ntawm txoj cai concentration. calcium tsawg dhau ua rau qaug zog, nyob rau hauv - teeb gel. Ntau dhau ua rau brittle, grainy kev ntxhib los mos. Qhov nyiaj tshuav raug yog nyob ntawm qib pectin tshwj xeeb thiab cov ntsiab lus calcium ntuj ntawm cov txiv hmab txiv ntoo siv - cov tuam txhab yuav tsum xa mus rau tus neeg muag khoom pom zoo calcium -rau-pectin piv raws li qhov pib.

 

Dispersion.Pectin hmoov clumps yooj yim yog ntxiv ncaj qha rau cov kua. Ua ntej- sib tov nrog piam thaj los yog lwm yam khoom xyaw qhuav ua ntej hydration, thiab qhia nyob rau hauv agitation. Lumps uas tsim nyob rau theem no tsis yaj thaum ua noj thiab tsim kev ntxhib los mos ntawm cov khoom tiav.

 

 

Cov lus nug nquag

 

LM pectin puas tuaj yeem hloov pauv lub luag haujlwm ntawm cov piam thaj hauv jam?

 

Nws hloov cov gelling thiab dej -binding functions ntawm qab zib, yog. Tab sis qab zib kuj pab txhawb kom tsw qab thiab ua raws li kev khaws cia. Tsawg- qab zib jams siv LM pectin tseem xav tau kev tshuaj xyuas tag nrho - suav nrog kev hloov pauv pH, kev tswj hwm calcium, thiab cov tswv yim khaws cia - tsis yog kev sib pauv pectin xwb.

 

Vim li cas kuv qis - qab zib jam tseem ntws tom qab ntxiv LM pectin?

 

Qhov feem ntau yuav ua rau muaj calcium tsis txaus, pH sab nraum 3.0-3.5 ntau, pectin underdosing, los yog tsis zoo dispersion ua rau unhydrated clumps. Tshawb xyuas txhua qhov sib txawv ntawm qhov systematically ua ntej hloov kho ntau npaum.

 

Puas yog Pectin E440 haum rau huv - cov khoom lag luam?

 

Yog lawm. Pectin yog muab los ntawm citrus tev lossis txiv apple pomace thiab tau txais los ua cov khoom xyaw ntuj hauv huv - cov ntawv sau npe hauv ntau lub khw.

 

Puas pectin cuam tshuam qhov tsw ntawm jam?

 

Tsis yog. Ntawm cov qib kev siv ib txwm, pectin tsis muaj qhov cuam tshuam rau qhov tsw. Nws cov nyhuv yog tag nrho textural thiab structural.

 

Xaus

 

Txo cov piam thaj hauv jam hloov ntau dua li qab zib - nws cuam tshuam rau tag nrho cov qauv. Yog tsis muaj kev kho kom raug, kev ntxhib los mos tsis ruaj khov yog yuav luag tsis tuaj yeem zam.

 

Pectin E440 muab cov kev daws teeb meem los ntawm kev tsim kho cov gel network, txhim kho cov dej tuav, thiab tswj kom zoo ib yam. Nrog rau hom thiab cov qauv tsim, nws muaj peev xwm tsim tau qis - qab zib jams uas tseem xa cov neeg siv khoom zoo.

 

Raws li ib tug tshwj xeeb pectin tsum mob siab rau kev pab cov zaub mov manufacturers,Chemsinoyog tsav los ntawm lub hom phiaj kom ua zaub mov txawv, txhawb cov neeg tsim khoom noj kom tsim tau cov khoom zoo tshaj.
