Hauv cov zaub mov thiab kev lag luam pub noj, lub luag haujlwm tseem ceeb ntawm cov tshuaj tua kab mob yog inhibit microbial kev loj hlob thiab txuas ntxiv cov khoom txee lub neej, thaum txo qhov cuam tshuam rau qhov tsw thiab kev nyab xeeb. Txawm hais tias fumaric acid tsis yog ib txwm "muaj zog khaws cia," nws qhov tseem ceeb acidification muaj peev xwm thiab kev ruaj ntseg zoo ua rau nws muaj cov khoom siv acidic preservative los yog ib feem tseem ceeb ntawm cov txheej txheem preservative, qhia tshwj xeeb zoo hauv ntau daim ntawv thov.
I. Qhov Zoo Tshaj Plaws ntawm Fumaric Acid ua cov tshuaj tiv thaiv
Ua ntej,fumaric acidexerts nws cov nyhuv antibacterial los ntawm txo tus nqi pH. Feem ntau cov kab mob, cov poov xab, thiab pwm muaj qhov txwv tsis pub loj hlob hauv qhov chaw acidic. Fumaric acid tuaj yeem txo qis pH ntawm cov zaub mov lossis cov khoom noj, yog li inhibiting microbial reproduction. Qhov no "kev tswj hwm ib puag ncig" txoj kev khaws cia yog ntau nyob rau hauv txoj kab nrog qhov kev thov tam sim no rau cov tshuaj ntxiv me me nrog cov txheej txheem khaws cia kom meej.
Qhov thib ob, fumaric acid muaj qhov ruaj khov thiab ntev -cov nyhuv preservative. Fumaric acid muaj cov cua kub zoo thiab tsis yooj yim decomposed thaum lub sij hawm siab -kub ua, pasteurization, los yog ci, cia nws tswj cov kab mob ib puag ncig txawm tias tom qab ua. Cov yam ntxwv no ua rau nws tsim nyog rau cov khoom noj uas yuav tsum tau kho cua sov.
Thib peb, fumaric acid muaj hygroscopicity tsawg, uas yog qhov zoo rau kev khaws cia ntawm cov khoom qhuav. Piv nrog rau qee qhov yooj yim hygroscopic organic acids, fumaric acid tsis yooj yim clump nyob rau hauv hmoov cov khoom noj, khoom noj khoom haus, premixes, thiab pub, thiab muaj peev xwm tuav ruaj khov acidity thiab preservative teebmeem rau lub sij hawm ntev, pab mus cuag cov khoom cia lub neej.
Plaub, fumaric acid tuaj yeem tsim kev sib koom ua ke nrog lwm cov tshuaj tua kab mob. Nyob rau hauv cov formulations tiag tiag, fumaric acid feem ntau yog siv ua ke nrog poov tshuaj sorbate, sodium benzoate, los yog lwm yam organic acids. Los ntawm kev txo qis pH ntawm lub cev, nws tuaj yeem txhim kho cov tshuaj tua kab mob zoo ntawm cov tshuaj tua kab mob no, yog li ua tiav cov txiaj ntsig zoo tshaj plaws thaum txo tag nrho cov tshuaj tua kab mob siv.
II. Cov ntawv thov ntawm Fumaric Acid hauv Kev Tiv Thaiv
Hauv kev lag luam khoom noj khoom haus, fumaric acid yog siv dav hauv dej haus, khoom qab zib, khoom ci, jellies, condiments, thiab khoom noj khoom haus los tswj microbial kev loj hlob thiab ua kom lub neej ntev. Hauv kev lag luam pub khoom noj, fumaric acid feem ntau yog siv los ua acidifying preservative los pab tiv thaiv kev tsim cov kab mob tsis zoo, txhim kho kev noj zaub mov, thiab pab txhawb kev noj qab haus huv ntawm tsiaj txhu. III. Kev ceev faj rau kev siv Fumaric Acid ua ib qho tshuaj tiv thaiv
Ua ntej, fumaric acid yog "indirect preservative," thiab nws cov nyhuv preservative feem ntau nyob ntawm pH tswj. Yog li ntawd, rau qhov nruab nrab lossis siab - cov khoom noj uas muaj dej noo uas muaj kev pheej hmoo ntawm cov kab mob microbial, kev siv fumaric acid ib leeg feem ntau tsis txaus thiab yuav tsum tau ua ke nrog lwm txoj kev khaws cia, xws li kev kho cua sov, ntim ntim, lossis cov txheej txheem khaws cia sib xyaw.
Qhov thib ob, tus nqi ntxiv yuav tsum nruj me ntsis tswj thiab ua raws li cov cai tswj hwm. Ntau lub teb chaws thiab cheeb tsam muaj cov kev cai meej ntawm kev siv thiab ntau npaum li cas ntawm fumaric acid hauv zaub mov thiab pub. Kev siv ntau dhau tsis yog tsuas yog ua rau muaj kev pheej hmoo ua raws cai tab sis kuj tseem tuaj yeem cuam tshuam rau saj thiab kev nyab xeeb.
Tsis tas li ntawd, fumaric acid muaj solubility tsawg. Yog tias nws tsis txaus yaj hauv cov kua dej, nws yuav ua rau cov kua qaub tsis sib xws, yog li cuam tshuam rau cov nyhuv preservative. Yog li ntawd, nyob rau hauv daim ntawv thov, ua ntej -solving, cua sov kom yaj, los yog combining nrog rau lwm cov acids feem ntau yog saws los xyuas kom meej ruaj khov thiab uniform preservation.
Xaus
Zuag qhia tag nrho, fumaric acid, ua ib feem tseem ceeb ntawm kev khaws cia, muaj txiaj ntsig zoo hauv cov zaub mov thiab kev khaws cia vim nws muaj peev xwm acidification zoo, ruaj khov, thiab muaj txiaj ntsig zoo. Tsuav nws lub luag haujlwm khaws cia tau raug txhais kom raug, qhov ntau npaum li cas yog kev tswj hwm, thiab nws tau siv nrog rau lwm txoj kev khaws cia, fumaric acid tuaj yeem txhim kho kev ruaj ntseg thiab kev lag luam kev sib tw ntawm cov khoom thaum ua kom muaj kev nyab xeeb.
