Muaj nuj nqi
Bacteriostasis
Vanillin yog ib tug natural bacteriostatic tus neeg sawv cev, uas feem ntau yog ua ke nrog rau lwm yam bacteriostatic txoj kev nyob rau hauv cov zaub mov, thiab cov bacteriostatic nyhuv ntawm vanillin ntawm txawv hom yog txawv. Cov nyhuv inhibitory ntawm vanillin muaj feem xyuam rau nws cov concentration thiab pH nqi. Ntau dua vanillin concentration thiab qis pH tus nqi yog qhov tsim nyog rau kev txhim kho cov nyhuv inhibitory ntawm vanillin. Cov nyhuv inhibitory ntawm vanillin ntawm ntau hom sib txawv, thiab cov nyhuv inhibitory ntawm vanillin ntawm E. coli zoo dua li lwm hom. Vanillin tuaj yeem cuam tshuam ntau yam ntawm cov poov xab, thiab siab concentration ntawm vanillin tuaj yeem txhim kho nws cov nyhuv antibacterial, tab sis siab concentration ntawm vanillin tsis tuaj yeem tua cov poov xab tam sim ntawd. Txoj kev khaws cia tshiab sib xyaw ua kom paub txog cov txiaj ntsig sib koom ua ke ntawm cov neeg ua haujlwm tshiab (lossis cov txheej txheem khaws cia tshiab) thiab yog feem ntau lees txais txoj kev khaws cia tshiab rau txiv hmab txiv ntoo thiab zaub.
Vanillin kuj tseem ua lub luag haujlwm tseem ceeb hauv kev pab bacteriostasis thiab ua kom tsis muaj menyuam. Nyob rau theem no ntawm cov txheej txheem ntau lawm, kub 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 kho mob 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, cov khoom lag luam Browning thiab lwm yam teeb meem.
Antioxidant
Lub mechanism ntawm kev txiav txim ntawm antioxidants nrog cov qauv zoo sib xws yog txawv. Vanillin accelerates qhov kev tshem tawm ntawm cov dawb radicals feem ntau los ntawm cov khoom oxidation vanillin. Cov nyhuv antioxidant ntawm vanillin tuaj yeem txuas ntxiv lub txee lub neej ntawm cov zaub mov oily thiab npog li rancid saj.
