Vim li cas thiaj xav tau Emulsifiers hauv Peanut Butter?
Koj puas tau qhib lub hub ntawm cov txiv laum huab xeeb tsuas yog nrhiav cov txheej txheem roj ntab saum toj, nrog cov tshuaj txhuam hauv qab ua kom qhuav thiab tawv? Qhov no yog qhov teeb meem zoo tshaj plaws nrog txiv laum huab xeeb:roj sib cais.
Peanut butter yog tsim los ntawm kev sib tsoo txiv laum huab xeeb, uas ib txwm muaj li 50% roj. Yog tsis muaj cov stabilizers, cov roj no yuav maj mam sib cais los ntawm cov khoom siv lub sijhawm thiab nce mus rau saum npoo. Qhov tshwm sim no ua raws li Stokes Txoj Cai- nyob rau hauv lub ntiajteb txawj nqus, qhov qis dua - cov roj theem ntawm qhov ntom ntom yuav nce mus.
Txhawm rau daws qhov teeb meem no, kev lag luam khoom noj tau pom ib qho yooj yim tab sis siv tau zoo:ntxiv emulsifiers.
Emulsifiers yog cov molecules nrog cov qauv amphiphilic-ib kawg hlub dej (hydrophilic), thiab lwm yam hlub roj (lipophilic). Thaum ntxiv rau txiv laum huab xeeb, lawv muab lawv tus kheej tso rau ntawm qhov sib txuas ntawm cov roj thiab dej (lossis cov roj thiab cov khoom siv), tsim cov yeeb yaj kiab ruaj khov uas tiv thaiv cov roj los ntawm kev sib sau thiab nce.
Common Emulsifiers Siv Hauv Peanut Butter
Raws li kev tshawb fawb hauv tsev thiab thoob ntiaj teb, nrog rau kev siv ntau lawm, cov emulsifiers pom muaj nyob hauv txiv laum huab xeeb feem ntau suav nrog hom hauv qab no:
1 Glycerol Monostearate (GMS)
GMS yog ib qho ntawm feem ntau siv emulsifiers hauv kev lag luam zaub mov thiab kev xaiv classic rau stabilizing txiv laum huab xeeb.
HLB Value: Kwv yees li 3.8 (lipophilic)
Mechanism: GMS tsub kom lub viscosity ntawm txiv laum huab xeeb roj, tsim kom muaj ib tug crystalline network ntawm kuj tsis tshua muaj concentrations, zoo tiv thaiv cov roj sib cais.
Kev ua tau zoo: Cov kev tshawb fawb paub meej tias ntxiv me me ntawm GMS ua rau cov txiv laum huab xeeb ruaj khov thaum tuav lub qhov ncauj zoo thiab tsw
2 High Diglyceride Emulsifier (HiDi)
This is a specially designed emulsifier with a particularly high diglyceride content (>60%).
Kev sib xyaw: Ua los ntawm cov roj zaub (xws li taum pauv, canola, lossis txiv laum huab xeeb) nrog glycerol, feem ntau muaj cov sib xyaw ntawm mono- thiab diglycerides
Qhov Zoo Tshaj Plaws: Qhov no siab -diglyceride emulsifier ua haujlwm tau zoo ntawm cov roj theem, nce viscosity, thiab tseem ceeb tshaj plaws,tsis muaj trans fatty acids, zam qhov kev pheej hmoo ntawm kev noj qab haus huv cuam tshuam nrog cov tshuaj ib nrab hydrogenated roj emulsifiers
Kev ua tau zoo: Piv nrog rau kev lag luam stabilizers ua los ntawm hydrogenated cottonseed roj, HiDi emulsifiers tiv thaiv cov roj sib cais thaum tuav lub ntsej muag gloss, tiv thaiv qhov tsis zoo uas tuaj yeem tshwm sim nrog qee cov stabilizers.
3 Sodium Stearoyl Lactylate (SSL)
SSL yog ib qho anionic emulsifier dav siv hauv cov khoom ci thiab tseem ua lub luag haujlwm tseem ceeb hauv txiv laum huab xeeb.
HLB Value: 8-10 (hydrophilic)
Blending Applications: Kev tshawb fawb qhia tau hais tias ntxiv 0.03% SSL ua ke nrog lwm cov emulsifiers thiab cov thickeners ua tiav kev ruaj ntseg zoo hauv cov txiv laum huab xeeb cov dej haus, tsis muaj nag lossis rog ntab tom qab 6 lub hlis ntawm kev cia ntawm chav tsev kub.
4 Polyglycerol Esters (PGE)
Polyglycerol esters yog siab -kev ua haujlwm tsis yog- ionic emulsifiers.
HLB Value: Dav adjustable ntau yam (nyob ntawm seb hom fatty acid thiab℃ntawm polymerization)
Blending Applications: Kev tshawb fawb qhia tias ntxiv 0.10% PGE, nrog rau lwm cov emulsifiers thiab thickeners, optimizes stability ntawm txiv laum huab xeeb protein dej haus.
5 Sucrose Esters (SE)
Sucrose esters yog tsim los ntawm esterifying sucrose nrog fatty acids thiab tuaj yeem tsim nrog ntau yam HLB qhov tseem ceeb vim muaj ntau pawg hydroxyl nyob rau hauv hydrophilic feem.
Piv txwv daim ntawv thov: Lub tshuab patented qhia tau hais tias ntxiv sucrose esters rau txiv laum huab xeeb, ua ke nrog kev ua haujlwm tshwj xeeb (cua sov rau 70℃rau 20-25 feeb, txias rau 40-45℃ua ntej sau), tiv thaiv cov roj sib cais thiab caking thaum lub neej txee.

Xaus
Emulsifiers hauv txiv laum huab xeeb yuav zoo li tsis tseem ceeb, tab sis lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom zoo. Los ntawm ib txwm GMS mus rau kev noj qab haus huv- taw qhia siab -diglyceride emulsifiers thiab ua tib zoo tsim cov tshuab ua ke, emulsifier tshuab txuas ntxiv mus.
Rau cov neeg siv khoom, kev nkag siab txog cov emulsifiers no pab ua kom paub kev xaiv thaum nyeem cov ntawv cim khoom. Rau cov tuam txhab tsim khoom, xaiv txoj cai emulsifier (lossis cov txheej txheem sib xyaw) yuav tsum muaj kev sib npaug, tus nqi, kev hloov pauv, thiab cov neeg siv khoom xav tau "cov ntawv huv" thiab cov cwj pwm noj qab haus huv.
Kev tshawb fawb ntawm emulsifiers ua kom ntseeg tau tias txhua zaus koj qhib lub thawv ntawm txiv laum huab xeeb, koj pom cov khoom sib xws, zoo sib xws, sib kis tau zoo kawg nkaus - ib yam li nws yuav tsum ua.
