Tsis tas li ntawd, nws kuj tseem tuaj yeem siv los ua tus neeg saib xyuas polishing hauv kev lag luam electroplating, ua tus neeg sawv cev ripening hauv kev ua liaj ua teb, ua cov deodorant hauv cov khoom siv roj hmab, ua cov tshuaj tiv thaiv tawv tawv hauv cov khoom yas thiab ua cov tshuaj nruab nrab, thiab lwm yam. dav siv.

1. Tshuaj tua kab mob
Vanillin yog ib qho tshuaj tua kab mob ntuj, uas feem ntau ua ke nrog lwm cov tshuaj tua kab mob hauv cov zaub mov, thiab vanillin muaj cov kab mob sib txawv ntawm cov kab mob sib txawv. Cov nyhuv antibacterial ntawm vanillin muaj feem xyuam rau nws cov concentration thiab pH nqi. Ntau dua vanillin concentration thiab qis pH tus nqi yog qhov zoo los txhim kho cov nyhuv antibacterial ntawm vanillin. Cov nyhuv antibacterial ntawm vanillin ntawm ntau hom kab mob sib txawv, vanillin muaj cov kab mob zoo dua ntawm Escherichia coli dua li lwm hom. Vanillin muaj cov nyhuv inhibitory ntawm ntau yam poov xab, thiab siab ntau ntawm vanillin tau txais txiaj ntsig los txhim kho nws cov kab mob tua kab mob, tab sis cov ntsiab lus siab ntawm vanillin tsis tuaj yeem tua cov poov xab tam sim ntawd. Composite fresh-keeping realizes synergistic effect of fresh-keeping agents (los yog cov kev khaws cia tshiab), thiab yog ib qho kev lees paub ntawm cov txiv hmab txiv ntoo thiab zaub tshiab. Cov tshuaj tua kab mob ntawm cov txuj lom feem ntau muaj kev sib koom ua ke thiab cov koob tshuaj tsawg dua li kev siv ib zaug, piv txwv li: txhawm rau tiv thaiv cov kab mob dub rau Aspergillus, cov tshuaj tua kab mob zoo ntawm vanillin ib leeg yog 0.5%, thiab sib tov ntawm { {6}}.05% vanillin thiab 0.0025% cinnamaldehyde tuaj yeem ua rau cov kab mob tua kab mob.
Vanillin kuj tseem ua lub luag haujlwm tseem ceeb hauv kev pab tiv thaiv kab mob thiab kab mob bactericidal. Hauv cov txheej txheem tsim khoom tam sim no, thermal sterilization tseem yog txoj kev ua kom tsis muaj menyuam ntau tshaj plaws hauv kev ua kua txiv hmab txiv ntoo, thiab nws txoj kev ua haujlwm feem ntau yog pasteurization thiab kub-kub instantaneous sterilization. Txoj kev ua kom tsis muaj menyuam ib txwm ua rau kev puas tsuaj ntawm cov as-ham hauv cov kua txiv hmab txiv ntoo thiab browning ntawm cov khoom.
2. Anti-oxidation
Antioxidants nrog cov qauv zoo sib xws muaj cov txheej txheem sib txawv. Vanillin tsuas yog ua kom nrawm nrawm ntawm cov dawb radicals los ntawm oxidizing cov khoom vanillic acid. Npog. Lub isomer ntawm vanillin, o-vanillin (3-methoxy-2-hydroxybenzaldehyde), tau pom tias yuav tshem tawm peroxynitroso anions, tab sis tsis yog ib qho zoo dawb radical scavenger .
3. Ua kom ruaj khov rau lwm cov khoom xyaw hauv zaub mov
Cov kev tshawb fawb tau pom tias cov tshuaj tiv thaiv ntawm vanillin pab kom stabilize lwm cov khoom xyaw hauv cov zaub mov: Resveratrol yog ib yam khoom muaj txiaj ntsig zoo. Txhawm rau txhim kho nws txoj kev ruaj ntseg thiab ua tiav nws cov txiaj ntsig ua haujlwm, cov khoom siv tshuaj tiv thaiv ntawm vanillin thiab chitosan Cov tsim reticular chitosan microspheres yog coated nrog resveratrol, uas pab tswj kev tso tawm ntawm resveratrol; cov khoom condensation ntawm vanillin thiab amino pawg muaj peev xwm ua tau zoo nrog cov hlau ions, uas tuaj yeem txhim kho nws txoj kev ruaj ntseg ntawm cov khoom siv.
