Lawv lub luag haujlwm tseem ceeb suav nrog kev tiv thaiv kev tsim cov dej khov nab kuab, txo qis qis, thiab ua kom lub zog tag nrho ntawm cov dej khov. Nov yog ntau hom ice cream stabilizers:

Guar Gum

Guar gum yog muab los ntawm guar taum, uas feem ntau loj hlob hauv Is Nrias teb thiab Pakistan. Nws ua raws li tus neeg sawv cev thickening thiab stabilizer uas pab tiv thaiv cov dej khov siv lead ua los ntawm kev cuam tshuam nrog dej molecules.

Carrageenan

Carrageenan yog muab rho tawm los ntawm cov seaweed liab, thiab muaj ntau hom (piv txwv li, kappa, iota, thiab lambda) nrog cov gel sib txawv. Nws ua hauj lwm raws li tus neeg sawv cev gelling thiab stabilizer, pab txhawb lub creaminess ntawm ice cream thiab tiv thaiv kev sib cais ntawm cov khoom xyaw.

Xanthan Gum

Xanthan gum yog tsim los ntawm fermentation ntawm cov suab thaj los ntawm cov kab mob Xanthomonas campestris.Xanthan cov pos hniavyog ntau yam stabilizer uas pab txhim kho viscosity thiab kev ntxhib los mos ntawm ice cream. Nws kuj ua raws li tus neeg sawv cev thickening thiab tiv thaiv ice crystals los ntawm kev sib sau.

Cellulose Gum (CMC)

Cellulose Gum (CMC) yog muab los ntawm cellulose, feem ntau yog muab rho tawm los ntawm ntoo pulp los yog paj rwb. Nws yog ib qho dej-soluble stabilizer uas txhim kho cov creaminess ntawm cov dej khov los ntawm kev tiv thaiv cov dej khov thiab ua kom muaj kev ntxhib los mos.

Dab tsi emulsifiers siv hauv ice cream?

Lawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib cais ntawm ob lub ntsiab lus no thiab ua rau muaj kev ntxhib los mos thiab creamy. Nov yog qee cov ice cream emulsifiers:

Mono- thiab Diglycerides

Mono- thiab Diglycerides feem ntau yog muab los ntawm cov roj cog, xws li taum pauv los yog xibtes roj. Mono- thiab diglycerides ua raws li emulsifiers, txhim kho kev ruaj ntseg ntawm cov rog theem hauv cov dej khov. Lawv kuj pab txhawb kom smoother kev ntxhib los mos.

Polysorbate 80

Polysorbate 80 yog muab los ntawm sorbitol thiab oleic acid, feem ntau yog los ntawm cov roj zaub.Polysorbate 80 rau muagyog ib tug hydrophilic emulsifier uas pab tsim ib tug ruaj khov emulsion ntawm cov roj thiab dej theem nyob rau hauv ice cream, pab txhawb creaminess.

Soy Lecithin

Soy lecithin yog lub ntuj emulsifier uas pab tswj kom muaj kev ruaj khov ntawm cov rog thoob plaws hauv cov dej khov sib xyaw. Nws pab txhawb kom smoother thiab zoo ib yam zoo nkauj.

Dab tsi yog Preservatives siv hauv Ice Cream?

Preservatives yog siv nyob rau hauv ice cream kom ntev nws txee lub neej los ntawm inhibiting kev loj hlob ntawm cov kab mob, xws li kab mob, poov xab, thiab pwm. Txawm li cas los xij, kev siv cov tshuaj tua kab mob hauv cov dej khov yog feem ntau tsawg dua piv rau lwm cov khoom noj. Qhov txias txias ntawm ice cream nws tus kheej yuav pab kom qeeb microbial kev loj hlob. Nov yog qee yam khoom noj khoom haus ice cream preservatives:

Sorbic acid

Sorbic acid thiab nws cov ntsev, xws li poov tshuaj sorbate, feem ntau yog siv los tiv thaiv kev loj hlob ntawm cov pwm thiab cov poov xab. Lawv muaj txiaj ntsig zoo ntawm qhov tsis tshua muaj siab thiab siv dav hauv kev lag luam khoom noj.

Benzoic Acid

Benzoic acid thiab nws cov ntsev, zoo lisodium benzoate hmoov, yog siv los ua preservatives los tiv thaiv kev loj hlob ntawm cov kab mob thiab fungi. Lawv tshwj xeeb tshaj yog zoo nyob rau hauv acidic ib puag ncig. Dhau li ntawm nws siv hauv ice cream, sodium benzoate yog ua hauj lwm nyob rau hauv ntau yam dej haus, kaus poom txiv hmab txiv ntoo thiab zaub, jams thiab jellies.

Lub Takeaway

Txhawm rau qhwv, ice cream additives sawv ua cov khoom tseem ceeb ntawm qhov kev zoo siab khov. Cov khoom xyaw ua tib zoo xaiv, suav nrog stabilizers, emulsifiers, thiab preservatives, ua haujlwm sib haum xeeb los txhawb qhov kev ntxhib los mos, sib xws, thiab tag nrho cov kev xav ntawm cov dej khov.
