Saib qee cov khoom noj uas koj yuav hauv lub khw. Piv txwv li, tej yam xws li mayonnaise, ice cream, chocolate, peanut butter. Lawv du thiab sib npaug li cas? Lawv tuaj yeem khaws cia tau ntev. Koj puas tau xav tsis thoob tias lawv ua li cas zoo li no? Ib qho ntawm cov khoom xyaw zais cia tom qab qhov no hu ua "emulsifiers." Hnub no peb yuav tham txog cov emulsifiers uas ib txwm nyob ntawm peb lub phaj yog dab tsi thiab seb lawv puas zoo lossis phem rau peb lub cev.
Yog li, cov emulsifiers no yog dab tsi?
Hais yooj yim xwb, cov tshuaj emulsifiers yog cov tshuaj uas khi ob yam ua ke uas tsis xav sib tov, zoo li cov phooj ywg, thiab sib tov ua ke. Piv txwv zoo tshaj plaws yog roj thiab dej. Txawm koj co lub raj mis hauv tsev ntau npaum li cas los xij nrog me ntsis dej thiab me ntsis roj txiv maj phaub, tom qab ib pliag cov roj yuav rov qab los rau saum thiab sib cais, puas yog? Cov tshuaj emulsifiers yog cov tshuaj uas yuam ob lub kua uas tsis sib tov ua ke thiab pab kom cov khoom sib tov ruaj khov.
Cov no yog ntxiv rau ntau yam khoom noj uas tau ua tiav thiab ntim khoom uas peb noj.
- Mayonnaise: Sib tov roj thiab vinegar (ua los ntawm dej) ua ke.
- Kas fes khov: Txo cov dej khov ua tej daim me me thiab muab cov qauv du thiab creamy.
- Chocolate: Khaws cov cocoa butter thiab cocoa hmoov sib cais.
- Cov khoom noj qhob cij thiab cov khoom ci ci: Ua kom lub txee ntev dua thiab txo qhov qhuav.
- Cov kua ntses thiab cov kua zaub xam lav: Khaws cov roj thiab lwm yam khoom ua kua kom tuab ib yam, tsis txhob sib cais.
Cov no raug ntxiv rau hauv cov khoom noj kom zoo nkauj dua, ua rau lawv du, thiab ua rau lawv lub txee ntev dua. Txawm hais tias qee cov emulsifiers yog ua los ntawm cov nroj tsuag (piv txwv li, taum pauv), feem ntau yog ua los ntawm cov khoom tsiaj, thiab feem ntau yog tsim los ntawm cov khoom siv hauv chav kuaj.
Tsis yog tsuas yog nyob rau hauv cov khoom noj xwb, tab sis kuj nyob rau hauv cov khoom siv tu tawv nqaij, tshuaj pleev, thiab tshuaj uas peb siv, cov emulsifiers no yog siv los pab kom cov khoom xyaw roj thiab dej sib xyaw ua ke.
Tej no ua haujlwm li cas? Cia peb saib nws me ntsis raws li kev tshawb fawb.
Qhov no yooj yim to taub heev. Xav txog lub molecule emulsifier zoo li lub hlau nplaum me me, tab sis muaj ob sab uas ua haujlwm ua ob txoj kev.
1. Ib sab nyiam dej: Peb hu qhov no ua hydrophilic. Sab no nyiam cov dej molecules.
2. Sab tod nyiam roj: Qhov no hu ua hydrophobic. Sab no nyiam cov roj molecules.
Tam sim no xav txog tias peb ntxiv cov tshuaj emulsifier rau hauv cov roj thiab dej sib tov. Qhov tshwm sim yog tias cov molecule emulsifier mus thiab sib sau ua ke ib puag ncig cov roj me me. Lawv cov sab uas nyiam roj tig mus rau cov roj thiab tuav nws kom nruj. Tib lub sijhawm, lawv cov sab uas nyiam dej tig mus rau sab nraud thiab ua phooj ywg nrog cov dej nyob ib puag ncig.
Ua li no, txawm tias cov roj tee dej ntab hauv dej los xij, lawv tsis raug tso cai sib sau ua ke los ua ib txheej roj loj. Qhov no yog vim li cas peb thiaj li tau txais cov khoom sib xyaw du thiab ruaj khov. Mis nyuj yog ib qho piv txwv zoo ntawm cov emulsion uas tshwm sim ntuj. Margarine yog qhov sib txawv , ib qho sib xyaw ntawm cov dej tee dej hauv roj.
Cov hom emulsifiers tseem ceeb pom muaj nyob rau hauv cov khoom noj thiab cov khoom tu tawv nqaij
Muaj ntau hom emulsifiers nyob rau hauv cov khoom noj thiab cov tshuaj pleev uas peb noj. Nws yog ib qho zoo kom paub txog qee yam ntawm cov no.
| Hom emulsifier | Qhov chaw | Feem ntau muaj dab tsi |
|---|---|---|
| Taum pauv Lecithin | Taum pauv, qe qe | Cov kua zaub xas lav, cov khoom ci qhob cij, chocolate |
| Carrageenan | Cov dej hiav txwv | Kas fes khov, mis nyuj yogurt, nqaij ua tiav |
| Mono- thiab diglycerides | Cov roj zaub, cov roj tsiaj | Kas fes khov, ncuav mog qab zib, mov ci, margarine |
| Carboxymethylcellulose (CMC) | Khoom siv hluavtaws | Cov dej khov nab kuab, cov kua ntses, cov khoom ci qhob cij |
| Polysorbate 80 | Khoom siv hluavtaws | Cov txiv lws suav, ice cream, cov vitamins |
| Sodium Lauryl Sulfate (SLS) | Khoom siv hluavtaws | Tshuaj zawv plaub hau, xab npum, tshuaj txhuam hniav, tshuaj pleev ib ce rau daim tawv nqaij |
Lo lus nug tseem ceeb tshaj plaws: Cov emulsifiers puas phem rau lub cev tiag?
Qhov no yog qhov tseem ceeb tshaj plaws uas peb txhua tus yuav tsum paub. Cov kev tshawb fawb tsis ntev los no tau qhia txog qee qhov kev pheej hmoo hauv qhov no.
Kev cuam tshuam rau kev noj qab haus huv ntawm txoj hnyuv
Peb txoj hnyuv tsis yog ib lub raj uas zaub mov hla xwb. Lawv yog lub tsev rau ntau txhiab lab tus kab mob me me (cov kab mob zoo) uas tseem ceeb rau peb txoj kev noj qab haus huv. Peb hu qhov no ua cov kab mob hauv plab . Cov kab mob zoo no pab peb zom zaub mov, tsim cov vitamins, thiab ua kom peb lub cev tiv thaiv kab mob muaj zog.
Kev tshawb fawb tau pom tias qee cov khoom siv emulsifiers cuav tuaj yeem cuam tshuam qhov sib npaug ntawm cov kab mob zoo no hauv peb txoj hnyuv.
Ib txoj kev tshawb fawb xyoo 2021 pom tias ob hom tshuaj emulsifiers cuav, tshwj xeeb yog carboxymethylcellulose (CMC) thiab polysorbate 80 , ua rau cov kab mob zoo hauv plab puas tsuaj thiab ua rau muaj kev pheej hmoo ntawm kev o ntawm plab hnyuv .
Cov mob o ntev no tuaj yeem ua rau muaj mob plab hnyuv (IBD), xws li mob Crohn thiab mob ulcerative colitis . Lwm cov kev tshawb fawb kuj qhia tias lawv yuav muaj feem cuam tshuam rau cov mob xws li kev rog dhau, mob ntshav qab zib hom 2, thiab mob plawv.
Cov nyhuv rau ntawm daim tawv nqaij
Cov tshuaj emulsifiers hauv qee cov khoom siv saib xyuas tawv nqaij, tshwj xeeb tshaj yog cov uas muaj sulfates, xws li SLS, tuaj yeem ua rau qhuav, khaus, thiab ua puas rau txheej tiv thaiv ntuj ntawm daim tawv nqaij. Lawv kuj tseem tuaj yeem ua rau muaj kev tsis haum tshuaj rau cov neeg uas muaj tawv nqaij rhiab heev.
Yog li ntawd, peb yuav ua li cas? Peb yuav tiv thaiv peb tus kheej li cas ntawm cov no?
Hnov txhua yam no tuaj yeem ua rau kuv ntshai me ntsis. Tiam sis tsis muaj dab tsi yuav tsum txhawj txog. Qhov tseem ceeb tshaj plaws yog kom paub txog cov khoom noj thiab cov khoom uas peb yuav.
1. Nyeem cov ntawv lo:Thaum koj yuav ib yam dab tsi hauv lub khw, ua ib tug cwj pwm nyeem cov npe khoom xyaw. Saib seb puas muaj cov tshuaj emulsifiers cuav uas tau hais los saum toj no.
2. Txo cov khoom noj uas ua tiav lawm: Txo koj cov khoom noj uas ntim thiab ua tiav lawm ntau li ntau tau. Hloov chaw, noj cov khoom noj ntuj xws li zaub tshiab, txiv hmab txiv ntoo, thiab cov nplej tag nrho . Yog tias koj ua koj cov zaub mov hauv tsev, koj muaj kev tswj hwm tag nrho rau yam koj noj.
3. Ceev faj nrog cov khoom siv saib xyuas tawv nqaij: Yog tias koj muaj tawv nqaij rhiab heev, xaiv cov khoom uas muaj daim ntawv lo "sulfate-free." Ua ntej siv cov khoom tshiab, sim ib daim tawv nqaij kom pom tias koj puas muaj kev tsis haum tshuaj.
Qhov tseem ceeb tshaj plaws yog muab cov khoom noj uas yog ntuj thiab tag nrho tso ua ntej ntau li ntau tau. Tsis yog txhua lub pob khoom uas peb yuav los ntawm lub khw yog qhov tseem ceeb rau peb lub neej.
Kev tshawb nrhiav txog qhov no tseem tab tom ua mus, yog li qhov kev nqis tes ua zoo tshaj plaws rau tam sim no yog txwv koj cov khoom noj ua tiav uas muaj cov khoom emulsifiers dag kom ntau li ntau tau.
