Cov Khoom Noj Emulsifiers Yog Dab Tsi
Oct 20, 2020
Sodium stearoyl lactate (SSL), calcium stearoyl lactate (CSL), diacetyl tartrate monoglyceride (hnub tim), sucrose fatty ester (SE) thiab distilled monoglyceride (dmg) yog qhov feem ntau siv emulsifiers hauv mov tsis zoo. Los ntawm kev sib cuam tshuam ntawm cov hmoov txhuv nplej siab thiab cov protein nyob hauv cov hmoov nplej, txhua yam emulsifiers tsim txoj hauv kev, uas tuaj yeem ua kom muaj zog gluten, txhim kho kev ua tiav, txhim kho cov nqaij cij pliav, thiab ua kom ntev lub txee lub neej. Tus nqi ntxiv ntawm emulsifiers feem ntau yog 0.2% - 0.5% (hmoov nplej).
Sodium stearoyl lactate / calcium (SSL / CSL)
Nws muaj cov nyhuv ntawm muaj zog gluten khaws cia. Ntawm ib sab tes, nws muaj kev sib txuam nrog cov protein tsim cov txheej txheem gluten protein ntau, uas ua rau lub ntsej muag gluten ntau dua thiab ywj, txhim kho cov roj tuav muaj peev xwm ntawm poov fermented ua khob noom cookie thiab nce ntim ntawm cov ncuav ci; ntawm qhov tod tes, nws cuam tshuam nrog amylose los tsim insoluble complex, yog li inhibiting kev laus ntawm amylose thiab khaws cov freshness ntawm ci ncuav. SSL / CSL tuaj yeem txhim kho qhov muag muag ntawm lub ncuav thaum nce qhov ntim ntawm cov khob cij. Txawm li cas los xij, thaum ua ke nrog lwm emulsifiers, nws cov nyhuv ua tau zoo yuav tsis muaj zog.
Diacetyl tartrate monoglyceride (hnub tim)
Nws tuaj yeem cuam tshuam nrog cov protein, txhim kho cov roj tuav muaj peev xwm ntawm fermented khob noom cookie, thiab nce ntim thiab elasticity ntawm qhob cij. Cov nyhuv no yog pom tseeb dua hauv kev npaj ntawm cov hmoov nplej muag. Txij li pom los ntawm kev nce ntim ntawm lub khob cij, cov nyhuv ntawm hnub tim yog qhov zoo tshaj plaws ntawm ntau cov emulsifiers, thiab nws tseem yog txoj hauv kev zoo tshaj los hloov cov potassium bromate.
Sucrose fatty acid ester (SE)
Sucrose monofatty acid ester yog dav siv hauv khob cij tsis zoo. Nws tuaj yeem txhim kho lub crispness ntawm qhob cij, txhim kho cov viscosity ntawm cov hmoov txhuv nplej siab, lub khob cij ntim thiab cov qauv lus ua ke, thiab tiv thaiv kev laus. Thaum siv cov khob noom cookie khov ua cov qhob cij, ntxiv sucrose ester tuaj yeem tiv thaiv kev ua khob noom ua kom tsis zoo.
Ua tus suav cov monoglyceride (dmg)
Lub luag haujlwm tseem ceeb yog ua lub ntsej muag muag ntawm lub khob cij qauv, kom tiv thaiv kev laus thiab tshiab ntawm qhob cij, thiab muab sib tov nws nrog lwm cov emulsifiers.
Khoom noj emulsifier yog ib hom tshuaj uas tuaj yeem txhim kho qhov nro ntawm ntau yam hauv cov txheej txheem hauv emulsion thiab tsim cov nplaim hluav taws xob tsis zoo los yog emulsion, tseem hu ua surfactant. Hauv lwm cov lus, nws yog hom khoom noj khoom haus ntxiv uas tuaj yeem hloov cov kua dej ua kua rau hauv kev sib cais tsis haum (emulsion) thiab ntxiv ib qho me me ntawm nws kom txo tau qhov cuam tshuam cuam tshuam ntawm cov roj-dej theem thiab tsim emulsifying effect.
