Calcium Propionatehauv Cov Ntawv Thov Pub Noj

Cov Haujlwm

• Kev Tiv Thaiv Pwm & Poov Xeb: Ua kom zoo tiv thaiv kev loj hlob ntawm pwm, poov xab, thiab qee yam kab mob, ua rau nws tsim nyog rau cov pub uas yooj yim puas tsuaj hauv cov chaw muaj dej noo ntau (piv txwv li, cov nplej, cov pub sib xyaw).
• Kev Nyab Xeeb Siab: Metabolized rau hauv propionic acid (ib qho roj fatty acid luv luv) hauv cov tsiaj, koom nrog kev ua haujlwm ntawm lub zog ib txwm muaj. Nws muaj kev lom tsawg heev thiab siv dav hauv nqaij qaib, npua, tsiaj txhu, thiab ntau ntxiv.
• Kev Ruaj Ntseg Zoo: Tsis zoo li propionic acid, calcium propionate tsis yog corrosive, yooj yim dua rau khaws cia, thiab sib tov sib npaug.

Cov ntawv thov

• Feem ntau siv rau tsiaj txhu, nqaij qaib, khoom noj rau tsiaj txhu hauv dej, thiab khoom noj tsiaj. Qhov ntau npaum li cas uas pom zoo kom siv yog 0.1%–0.3% (kho raws li qhov noo noo ntawm cov khoom noj thiab qhov chaw khaws cia).
• Hauv cov tsiaj txhu uas noj zaub mov ruminant, nws kuj ua haujlwm ua lub zog ua ntej, txhawb kev loj hlob ntawm cov kab mob hauv rumen.

Cov kev ceev faj

• Cov ntau dhau yuav cuam tshuam me ntsis rau qhov saj (qhov saj qaub me ntsis), txawm tias tsawg dua li propionic acid.
• Xyuas kom sib tov sib npaug kom tsis txhob muaj cov khoom sib xyaw ntau hauv zos.

Benzoic Acid hauv Cov Ntawv Thov Pub Noj

Cov Haujlwm

• Cov Tshuaj Tua Kab Mob Dav Dav: Tiv thaiv cov kab mob (piv txwv li,Kab mob Salmonella,E. coli) thiab pwm, nrog kev ua haujlwm zoo dua hauv cov chaw acidic (zoo tshaj plaws ntawm pH <4.5).
• Kev Txhawb Kev Loj Hlob: Hauv cov pub npua (tshwj xeeb tshaj yog cov menyuam npua), nws txo qis pH hauv plab hnyuv, tswj cov kab mob phem, txhim kho kev nqus cov as-ham, thiab ua rau qhov hnyav nce txhua hnub.
• Kev Ua Haujlwm ntawm Lub Cev: Sib xyaw nrog glycine hauv lub siab kom tsim tau hippuric acid rau kev tso zis. Kev noj ntau dhau yuav ua rau lub siab/lub raum hnyav dua.

Cov ntawv thov

• Feem ntau siv rau hauv npua (tshwj xeeb yog cov menyuam npua) thiab cov khoom noj qaib. Cov tshuaj uas EU pom zoo yog 0.5%–1% (ua benzoic acid).
• Cov teebmeem synergistic thaum ua ke nrog propionates (piv txwv li, calcium propionate) rau kev txhim kho pwm inhibition.

Cov kev ceev faj

• Kev Txwv Kev Siv Tshuaj Nruj: Qee thaj chaw txwv kev siv (piv txwv li, Tuam Tshoj cov cai tswj kev pub mis txwv rau ≤0.1% hauv cov menyuam npua pub).
• Kev Ua Haujlwm Zoo Raws Li pH: Tsis tshua muaj txiaj ntsig zoo hauv cov pub mis tsis muaj zog / alkaline; feem ntau ua ke nrog cov acidifiers.
• Kev Pheej Hmoo Mus Ntev: Cov tshuaj noj ntau dhau yuav cuam tshuam kev sib npaug ntawm cov kab mob hauv plab.

Kev Sib Piv Cov Lus Qhia & Cov Tswv Yim Sib Xyaws

Cov Lus Qhia Txog Kev Cai Lij Choj

• Tuam Tshoj: Ua raws liCov Lus Qhia Txog Kev Nyab Xeeb ntawm Cov Khoom Noj Ntxiv—benzoic acid yog txwv nruj me ntsis (piv txwv li, ≤0.1% rau cov menyuam npua), thaum calcium propionate tsis muaj qhov txwv siab tshaj plaws.
• EU: Tso cai rau benzoic acid hauv cov pub npua (≤0.5–1%); calcium propionate tau txais kev pom zoo dav dav.
• Qauv: Qee cov chaw tsim khoom nyiam cov kev xaiv uas muaj kev nyab xeeb dua (piv txwv li, sodium diacetate, potassium sorbate) dua li benzoic acid.

Cov Ntsiab Lus Tseem Ceeb

1. Rau Kev Tswj Pwm: Calcium propionate muaj kev nyab xeeb dua thiab siv tau ntau yam rau feem ntau cov pub.
2. Rau Kev Tswj Kab Mob & Kev Loj Hlob: Benzoic acid zoo tshaj plaws hauv cov pub npua tab sis xav tau cov tshuaj nruj.
3. Txoj Kev Zoo Tshaj Plaws: Kev sib xyaw ua ke ob qho tib si (lossis nrog lwm cov tshuaj preservatives) ua kom muaj kev sib npaug ntawm kev tiv thaiv pwm, kev ua haujlwm tiv thaiv kab mob, thiab kev siv nyiaj tsim nyog.
