txheem
Qhov no yog qhov sib xyaw ua ke uas ua lub luag haujlwm ruaj khov hauv kev lag luam niaj hnub no. Ua tsaug rau lub xub ntiag ntawm lub caij no, nws muaj peev xwm tswj tau qhov sib xws ntawm ntau yam khoom. Hauv ntau cov khoom, cov ntsiab lus ntawm cov khoom sib xyaw ua kom cov viscosity.
Raws li rau cov nyhuv ntawm lub cev, qhov no yog ib qho kev nyab xeeb tag nrho. Cov khoom raug tso cai rau kev tsim khoom thiab siv hauv ntau lub tebchaws CIS.
Lwm yam
Cov no yog tag nrho-fledged stabilizing Cheebtsam. Lawv muaj txiaj ntsig zoo tswj cov viscosity kom zoo, kho qhov sib xws ntawm cov khoom. Siv ua emulsifiers. Cov tebchaw no muaj feem xyuam rau kev ua cov hmoov nplej nyoos, tsim cov txheej txheem txheej rau kev lag luam khoom noj.
E473 yog ib qho zoo li gel, nco txog cov qauv mos lossis cov hmoov dawb. Nws muaj qab ntxiag qab ntxiag qab ntxiag saj nrog cov lus qhia ntawm iab. Qee cov neeg sawv cev muaj cov roj sib xws uas zoo li cov tshuaj gel.
Cov ntsiab lus no muaj qhov tseem ceeb melting ntau yam. Kev tiv thaiv rau hydrolysis yog qhov muaj zog heev, cov cua sov ua haujlwm siab sib haum rau cov concentration ntawm qab zib. Thaum noj, E473 tsis zoo cleaved los ntawm enzymes thiab tsis absorbed zoo txaus. Kev cais tawm tshwm sim los ntawm cov qauv sib xws ntawm lub cev.
Tau txais kev sib txuas
Qhov no yog ib qho khoom siv hluavtaws. Synthesis tshwm sim vim kev txaus siab sai ntawm sucrose. Muaj ib txoj hauv kev sib npaug rau kev rho tawm cov sib xyaw ntawm saccharoglyceride. Cov txheej txheem reactive yog nqa tawm tsuas yog nyob rau hauv lub chaw kuaj mob nrog obligatory muaj cov khoom tsim nyog, reagents, reagents thiab txheej txheem catalysts.
Cov khoom xyaw muaj cov khoom xyaw txheem zaub mov - qab zib, fatty acid ntsiab. Vim cov txheej txheem nyuaj ntawm lawv cov synthesis, cov ntsiab lus tsis tuaj yeem hu ua cov qauv zoo tagnrho. E473 yog me ntsis soluble nyob rau hauv dej ib puag ncig, thiab nws cov txheej txheem yuav tsum tau yuav tsum tau kev twb kev txuas thiab kev cuam tshuam nrog lub glycol keeb.
Cov tebchaw no muaj ntau qhov tsis zoo. Lawv ntau lawm yog incredibly complex. Tsis tas li ntawd, yuav tsum tau ua kom huv tab sis kim heev los ntawm cov khoom siv hluavtaws, cov khoom siv catalyst thiab cov khoom hnyav yuav tsum tau ua. Qhov no ua rau kom tus nqi ntawm cov khoom kawg. Cov tau txais cov ntsiab lus tseem ceeb ntawm cov tshuaj sucrose yog insoluble, lawv cov txheej txheem yog nrog los ntawm kev poob tseem ceeb hauv cov concentration ntawm cov kuab tshuaj.
Spheres ntawm kev siv
Cov khoom tshwj xeeb ntawm E473 ua rau nws nrov ua tus shaper. Cov khoom muaj peev xwm muab tau ib qho kev sib xws rau cov khoom noj, raws li cov qauv tsim. Tsis tas li ntawd, lub stabilizing compound muaj qhov cuam tshuam loj ntawm qhov sib xws, qib ntawm viscosity ntawm cov khoom.
Qhov ua tau ntawm E473 hauv cov teeb meem ntawm emulsification yog qhov tshwj xeeb. Feem ntau, cov yam ntxwv zoo ntawm cov zaub mov stabilizer E473 yog siv nyob rau hauv cov txheej txheem ntawm cov khoom bakery. Nws ntseeg tau tias raws li kev siv tshuab, lub stabilizer tuaj yeem txhim kho cov khoom lag luam zoo, ua kom lawv cov kev xav tau thiab kev ua lag luam.
Feem ntau qhov kev sib txuas muaj nyob hauv:
- cream, mis nyuj haus;
- khoom qab zib;
- mousses thiab cream;
- khoom noj khoom haus;
- hmoov hauv paus rau cov kua ntses;
- ua txiv hmab txiv ntoo.
Lub preservative feem ntau yog siv nyob rau hauv ib tug xov tooj ntawm emulsions, cream thiab technical pastes. Synonymous lub npe nyob rau hauv lub ntiaj teb no kev ua lag luam: esters ntawm sucrose thiab fatty acids, Sucrose Esters ntawm Fatty Acids, E473.
Ua phem thiab muaj txiaj ntsig
Txog tam sim no, kev tshawb fawb hauv paus ntawm lub ntsiab lus tseem tsis tau raug kaw - kev sim ntawm txoj kev tshawb fawb tau ua nyob rau hauv ntau lub koom haum ntiaj teb. Txog niaj hnub no, cov zej zog tseem tsis tau nthuav tawm nrog cov pov thawj tseeb ntawm qhov muaj lossis tsis muaj kev puas tsuaj los ntawm E473 stabilizer. Yog li ntawd, tam sim no, ib qho kev sib txuas ntxiv yog siv los tsim cov khoom noj khoom haus. Tsuas muaj cov lus hais txog nws qhov tsis zoo.
Cov kws tshaj lij thoob ntiaj teb hauv kev tswj hwm kev tswj hwm tau tsim thiab txhim kho nyob rau theem kev cai lij choj tag nrho cov kev tso cai niaj hnub tau txais ntawm ib qho chaw txaus ntshai. Tom qab tag nrho, cov khoom noj khoom haus thiab cov khoom sib txuas, txawm tias muaj kev nyab xeeb, tsis muaj txiaj ntsig. Lawv yuav tsum tau siv nruj me ntsis nyob rau hauv ntau npaum.
Cov kws kho mob tshwj xeeb tshwj xeeb tshaj yog cov kev cai nruj heev. Tom qab tag nrho, qhov cuam tshuam rau cov me nyuam ntawm txhua qhov kev sib txuas yog qhov zoo heev. Qhov tshaj plaws yog tias txawm tias qhov tsawg kawg nkaus ntawm qee cov tshuaj lom neeg siv hauv kev lag luam khoom noj tuaj yeem ua mob rau tus menyuam. Thiab ib tug xov tooj ntawm "kev nyab xeeb" cov ntsiab lus feem ntau ntxiv txawm rau cov me nyuam mos cov qauv.
Esters ntawm sucrose thiab fatty acids yog ib qho tseem ceeb ntxiv rau daim ntawv qhia. Ntau qhov kev lag luam tseem ceeb tsis tuaj yeem ua yam tsis muaj kev sib txuas. Xws li cov ntsiab lus feem ntau yog siv rau hauv kev tsim ntau yam ntawm fermented mis nyuj cov khoom. Qhov no tuaj yeem suav nrog txhua yam khoom qab zib raws li qab zib, mis nyuj lossis dej khov. E473 tuaj yeem pom hauv cov khoom qab zib, khoom qab zib, khoom noj khoom haus. Nws muaj nyob rau hauv hmoov dej qab zib, mousses, sauces, confectionery cream. E473 stabilizer zoo heev rau kev kho cov txiv hmab txiv ntoo lossis lwm yam khoom noj. Ib qho tseem ceeb hauv kev tsim cov txiv hmab txiv ntoo ice, khoom qab zib, dej qab zib, cawv. Muaj pov thawj hais tias ib tug compound ntawm no yog siv los ua ib tug creamer rau haus thiab ua ib tug additive rau zaub mov. Qhov tshwj xeeb emulsifying muaj peev xwm ntawm lub caij tau pom nws lub hom phiaj hauv cov kua zaub, cov kaus poom broths.
Txoj Cai thiab Tshuaj
Cov qauv tsim rau kev noj txhua hnub ntawm cov ntsiab lus yog kwv yees li 10 mg. Nyob rau hauv lub cev, cellular qauv muaj peev xwm cleave lub E473 compound. Qhov no tshwm sim maj mam nrog kev pab ntawm enzymes. Yog li ntawd, cov suab thaj thiab ntau cov fatty acids raug tso tawm. Element E473 muaj kev tso cai siv rau hauv kev lag luam zaub mov hauv ntau lub xeev vim nws tsis muaj teeb meem. Esters tsis koom nrog lub caste ntawm allergenic ntsiab, tsis txhob ua phem rau lub cev, tsis provoke hypersensitivity.
Cia rau cov neeg mob
Qhov kawg txee lub neej ntawm emulsifiers yog txiav txim siab los ntawm cov yam ntxwv ntawm cov khoom tsim khoom. Qhov nruab nrab, lub sijhawm no mus txog ntau xyoo. Emulsifiers yuav tsum tau khaws cia rau hauv qhov chaw qhuav, tiv thaiv tshav ntuj thiab raug tshav kub ntev.
Kev ntim khoom yog ua tiav hauv cov thawv kaw nruj nreem. Cov khoom yog thauj los ntawm ib qho kev thauj mus los, tab sis tsuas yog hauv cov chaw them nyiaj xwb. Cov khoom tsis muaj tshuaj lom, muaj kev nyab xeeb rau lwm tus. Khaws rau hauv cov pob kaw. Nws yog ib qho tseem ceeb heev kom tsis txhob ya raws nkag mus.
Kev tsim khoom thiab kev siv cov khoom raug tso cai thoob ntiaj teb. Nws yog kev nyab xeeb kiag li, yog li ntawd, nws yog calmly siv tau rau tag nrho cov sectors ntawm kev lag luam. Kev sib txuas yog ruaj khov rau hauv txhua qhov chaw ntawm lub neej, tau ua tiav thiab ua rau muaj txiaj ntsig zoo rau noob neej.
