Dab tsi yog qhov additive E280?
E280 yog cov khoom noj ntxivPropionic Acid CAS 79-09-4.Propionic acid e280 yog ib qho tshwm sim ntawm cov organic. Nws yog ib tug pob tshab kua nrog ib tug pungent tsw. Nws lub luag haujlwm tseem ceeb yog ua cov tshuaj tua kab mob tiv thaiv kab mob, inhibiting kev loj hlob ntawm pwm thiab kab mob, thiab qee zaum siv los ua tus neeg sawv cev tsw. Nws cov qauv tshuaj yog CH₃CH₂COOH.
Propionic Acid E280 siv rau dab tsi?
Raws li cov khoom noj ntxiv, CAS 79-09-4 propionic acid (E280) yog siv dav hauv ntau yam khoom noj. Nws tiv thaiv cov khoom ci xws li khob cij, rye qhob cij, thiab pastries los ntawm molding. Hauv kev lag luam mis nyuj, nws yog siv rau hauv qee cov cheese thiab cov khoom siv mis nyuj.E280tseem muaj nyob rau hauv cov ntses fermented thiab ib txwm fermented zaub mov.
Propionic Acid ua haujlwm li cas?
Propionic acid cov txheej txheem ntawm kev khaws cia zoo ib yam li cov benzoic acid thiab sorbic acid. Qhov zoo tshaj pH ntau rau nws cov tshuaj tiv thaiv kab mob yog los ntawm 2.5 txog 5.5.
Nws yog daim ntawv tsis sib xws ntawm propionic acid uas muaj cov tshuaj tiv thaiv kab mob. Lub undissociated propionic acid nkag mus rau hauv microbial cell membrane thiab nkag mus rau hauv cytoplasm.
Thiab ces, nws accumulates thiab dissociates nquag uas txo cov pH sab hauv ntawm cov microbial thiab thaum kawg tiv thaiv kev loj hlob ntawm microbial los yog txawm tua lawv.
