Raws li ntau lub npe lag luam tshwj xeeb hauv tshuaj yej npuas txuas ntxiv nthuav dav hauv tebchaws thiab thoob ntiaj teb, tshuaj yej npuas tau maj mam nrov zuj zus, nrog rau qee lub npe lag luam txawm qhib "cov khw muag tshuaj yej npuas tshwj xeeb." Cov hlaws dai tapioca yeej ib txwm yog ib qho ntawm cov khoom siv sab saum toj hauv cov dej haus tshuaj yej, thiab tam sim no muaj cov cai tshiab rau tshuaj yej npuas.
Tom qab tso tawm ntawm Lub Tebchaws Cov Txheej Txheem Kev Nyab Xeeb Khoom Noj rau Kev Siv Cov Khoom Noj Ntxiv (GB2760-2024) (tom qab no hu ua "Txheej Txheem") thaum Lub Ob Hlis 2024, Cov Txheej Txheem tau raug siv tsis ntev los no. Nws hais tias dehydroacetic acid thiab nws cov ntsev sodium tsis tuaj yeem siv rau hauv butter thiab concentrated butter, cov khoom hmoov txhuv nplej siab, mov ci, ncuav mog qab zib, cov khoom ci thiab glazes, cov khoom nqaij ua ntej, thiab cov kua txiv hmab txiv ntoo thiab zaub (purees). Tsis tas li ntawd, qhov txwv kev siv siab tshaj plaws ntawm qhov nocov khoom noj khoom haus ntxivhauv cov zaub pickled tau raug hloov kho los ntawm 1g / kg rau 0.3g / kg.
Dab tsi yog dehydroacetic acid thiab nws cov ntsev sodium?Dehydroacetic acidthiab nws cov ntsev sodium yog siv dav ua cov tshuaj preservatives dav dav, paub txog lawv qhov zoo ntawm kev nyab xeeb thiab kev ruaj khov siab. Lawv tsis cuam tshuam los ntawm cov kua qaub-base thiab ruaj khov rau lub teeb thiab cua sov, zoo inhibiting kev loj hlob ntawm cov poov xab, pwm, thiab cov kab mob. Dehydroacetic acid thiab nws cov ntsev sodium muaj cov tshuaj lom tsawg thiab muaj kev nyab xeeb thaum siv hauv qhov ntau thiab qhov ntau teev los ntawm cov qauv; txawm li cas los xij, kev noj ntau dhau mus ntev tuaj yeem ua rau tib neeg muaj kev noj qab haus huv.
Qhov no thiab tshuaj yej npuas muaj dab tsi sib txuas? Qhov tseeb, ua ib qho ntawm cov khoom xyaw hauv cov dej haus tshuaj yej, cov "pearls" hauv tshuaj yej npuas, uas yog cov khoom lag luam hmoov txhuv nplej siab, kuj yuav raug txwv tsis pub siv sodium dehydroacetate. Tam sim no, muaj peb hom "pearl" toppings hauv kev lag luam tshuaj yej: pearls kub hauv chav tsev, pearls khov, thiab pearls ua noj sai, nrog rau ob hom thawj zaug muaj cov tshuaj preservatives. Yav dhau los, cov xov xwm tshaj tawm tau hais tias qee lub khw muag tshuaj yej npuas tsis dhau qhov kev tshuaj xyuas vim muaj dehydroacetic acid hauv cov tapioca pearls muag. Kev tshwm sim ntawm cov cai tshiab kuj txhais tau tias pearls tsim tom qab Lub Ob Hlis 8th uas muaj sodium dehydroacetate yuav raug nplua.
Tej yam zoo sib xws yuav ua rau kev lag luam no vam meej mus rau qee yam. Kev siv Tus Qauv no yuav yuam kom cov tuam txhab lag luam kho cov txheej txheem tsim cov tapioca pearls thiab nrhiav lwm txoj hauv kev rau dehydroacetic acid thiab nws cov ntsev sodium kom ntseeg tau tias muaj kev nyab xeeb ntawm cov zaub mov, ua rau cov nqi tsim khoom nce ntxiv. Tib lub sijhawm, txhawm rau kom tswj tau qhov saj thiab zoo ntawm cov pearls, cov tuam txhab lag luam yuav tsum tau nqis peev ntau dua rau kev tshawb fawb thiab kev txhim kho kom tshawb nrhiav cov thev naus laus zis tshiab.
Qee lub lag luam me lossis cov uas tsis muaj kev txawj ntse yuav tsis muaj peev xwm dais tau cov nqi siab ntawm kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom, ua rau lawv yuav tsum tawm hauv kev lag luam. Qhov sib txawv, cov npe loj uas muaj peev xwm tshawb fawb thiab kev txhim kho zoo thiab kev tswj hwm cov khoom xa tuaj yuav tsum siv lub sijhawm no los nthuav lawv cov feem ntawm kev ua lag luam thiab txuas ntxiv lawv txoj haujlwm ua lag luam, yog li ua kom nrawm dua kev hloov pauv kev lag luam.
Thaum cov hom tshuaj yej tsom mus rau kev txhim kho kev noj qab haus huv thiab zoo, kev nyab xeeb ntawm cov zaub mov tau dhau los ua lub zog rau kev tsim hom. Txawm hais tias cov khoom pearl tsuas yog ib qho ntawm ntau cov khoom xyaw hauv cov dej haus tshuaj yej, lawv txoj kev tswj hwm zoo tsis tuaj yeem tsis quav ntsej. Cov hom tshuaj yej yuav tsum tswj hwm qhov zoo ntawm cov khoom siv raw thiab xaiv cov neeg muab khoom ntawm tapioca pearls uas ua tau raws li cov qauv kom ntseeg tau tias ua raws li. Tib lub sijhawm, cov hom yuav tsum koom nrog kev tshawb fawb thiab kev txhim kho kom nrhiav tau cov txheej txheem khaws cia kom noj qab haus huv thiab ntuj dua, xws li siv cov nroj tsuag ntuj rau kev khaws cia. Hauv kev lag luam, lawv yuav tsum hais txog cov yam ntxwv kev noj qab haus huv thiab kev nyab xeeb ntawm lawv cov khoom kom tau raws li cov neeg siv khoom nrhiav kev noj qab haus huv thiab txhim kho lawv lub npe hom. Tsis tas li ntawd, cov hom yuav tsum tau them sai sai rau kev txhawb nqa kev cob qhia cov neeg ua haujlwm kom paub txog cov cai tshiab thiab kev hloov kho khoom, zam cov teeb meem kev nyab xeeb zaub mov vim kev ua haujlwm tsis raug thiab tswj hwm lub koob npe nrov ntawm hom.
