Muaj ntau cov tshuaj tiv thaiv pwm thiab cov kab mob los tiv thaiv kab mob muaj nyob hauv khw, xws li benzoic acid thiab calcium propionate. Yuav ua li cas lawv yuav tsum raug siv nyob rau hauv pub? Cia kuv saib lawv qhov txawv.

Calcium propionatethiabbenzoic acid yog ob feem ntau siv pub additives, feem ntau yog siv rau preservation, anti-pwm thiab antibacterial lub hom phiaj kom ntev lub txee lub neej ntawm pub thiab xyuas kom meej kev noj qab haus huv ntawm cov tsiaj.

Calcium Propionatehauv Feed Applications

Muaj nuj nqi

• Pwm & Poov xab Inhibition: Ua kom muaj txiaj ntsig zoo rau kev loj hlob ntawm cov pwm, cov poov xab, thiab qee cov kab mob, ua rau nws tshwj xeeb tshaj yog haum rau cov khoom noj uas yuav lwj hauv qhov chaw muaj dej noo (xws li, nplej, cov khoom sib xyaw).
• Kev nyab xeeb siab: Metabolized rau hauv propionic acid (lub ntuj luv- saw fatty acid) hauv cov tsiaj, koom nrog hauv ib txwm muaj zog metabolism. Nws muaj toxicity tsawg heev thiab yog dav siv nyob rau hauv cov nqaij qaib, swine, ruminants, thiab lwm yam.
• Kev ruaj ntseg zoo: Tsis zoo li propionic acid, calcium propionate tsis yog-corrosive, yooj yim rau khaws cia, thiab sib tov sib xyaw.

Daim ntawv thov

• Feem ntau siv nyob rau hauv cov tsiaj nyeg, nqaij qaib, aquaculture feed, thiab tsiaj noj. Cov tshuaj pom zoo yog feem ntau 0.1% -0.3% (hloov raws li cov khoom noj khoom haus thiab kev cia khoom).
• Nyob rau hauv ruminant pub, nws kuj ua raws li lub zog precursor, txhawb rumen microbial kev loj hlob.

Cov kev ceev faj

• Cov nyiaj ntau dhau tuaj yeem cuam tshuam me ntsis rau palatability (mob qaub saj), txawm tias tsawg dua propionic acid.
• Xyuas kom muaj kev sib xyaw ua ke kom tsis txhob muaj qhov sib xyaw ua ke siab.

Benzoic Acid hauv Feed Applications

Muaj nuj nqi

• Broad-Spectrum Antimicrobial: Inhibits kab mob (xws li,Salmonella,E. coli) thiab pwm, nrog txhim kho kev ua tau zoo nyob rau hauv acidic ib puag ncig (zoo ntawm pH <4.5).
• Kev Txhawb Kev Loj Hlob: Hauv swine pub (tshwj xeeb yog piglets), nws txo qis hauv plab pH, inhibits cov kab mob phem, txhim kho kev nqus, thiab txhawb nqa qhov hnyav txhua hnub.
• Metabolism: Conjugated nrog glycine nyob rau hauv lub siab los tsim hippuric acid rau excretion. Kev noj ntau dhau tuaj yeem ua rau lub siab / lub raum hnyav.

Daim ntawv thov

• Feem ntau siv hauv swine (tseem ceeb piglets) thiab nqaij qaib pub. EU-pom zoo npaum li cas yog 0.5% -1% (raws li benzoic acid).
• Synergistic teebmeem thaum ua ke nrog propionates (piv txwv li, calcium propionate) rau txhim kho pwm inhibition.

Cov kev ceev faj

• Kev txwv nruj nruj: Qee thaj tsam siv tau (piv txwv li, Tuam Tshoj txoj cai pub noj ntxiv txwv rau ≤0.1% hauv npua pub).
• pH-Dependent Efficacy: Tsawg zog hauv nruab nrab / alkaline txau; feem ntau ua ke nrog acidifiers.
• Kev pheej hmoo mus sij hawm ntev: koob tshuaj ntau yuav cuam tshuam plab microbiota tshuav nyiaj li cas.

Sib piv cov ntsiab lus & kev sib xyaw cov tswv yim

Regulatory Notes

• Tuam Tshoj: Ua rawsPub Additive Safety Guidelines-benzoic acid yog nruj me ntsis txwv (piv txwv li, ≤0.1% rau piglets), thaum calcium propionate tsis muaj kev txwv nruj.
• EU: Tso cai benzoic acid hauv swine pub (≤0.5-1%); calcium propionate yog dav pom zoo.
• Txoj Kev: Qee cov tuam txhab lag luam nyiam lwm txoj kev nyab xeeb (xws li sodium diacetate, potassium sorbate) tshaj benzoic acid.

Ntsiab Cai

1. Rau Pwm Tswjhwm: Calcium propionate muaj kev nyab xeeb dua thiab muaj ntau yam rau feem ntau pub.
2. Kev Tswj Kab Mob & Kev Loj Hlob: Benzoic acid excels nyob rau hauv piglet pub tab sis yuav tsum tau nruj npaum li cas.
3. Lub tswv yim zoo: Kev sib xyaw ob qho tib si (lossis nrog lwm cov tshuaj tua kab mob) sib npaug pwm inhibition, tshuaj tiv thaiv kab mob, thiab kev siv nyiaj txiag.
