Kunezinhlobo eziningi zemithi yokulwa nesikhunta kanye nemithi yokulwa namagciwane ezitholakala emakethe, njenge-benzoic acid kanye ne-calcium propionate. Kufanele zisetshenziswe kanjani ngendlela efanele ekudleni? Ake ngibheke umehluko wazo.

I-calcium propionatefuthii-benzoic acid yizithasiselo ezimbili zokudla ezisetshenziswa kakhulu, ezisetshenziswa kakhulu ukulondolozwa, ukulwa nesikhunta kanye nezinhloso zokulwa namagciwane ukuze kwandiswe impilo yokudla eshalofini nokuqinisekisa impilo yezilwane.

1. i-calcium propionate

Ifomula: 2(C3H6O2)·Ca

Ukubukeka: Impuphu emhlophe

Ukuhlolwa: 98%

I-Calcium Propionatekuzinhlelo zokusebenza zokuphakelayo

Imisebenzi

• Ukuvinjelwa Kwesikhunta Nemvubelo: Kuvimbela ngempumelelo ukukhula kwesikhunta, imvubelo, kanye namagciwane athile, okwenza kube kuhle kakhulu ekudleni okuvame ukonakala ezindaweni ezinomswakama omningi (isb., okusanhlamvu, ukudla okuhlanganisiwe).
• Ukuphepha Okuphezulu: Kuguqulwa kube yi-propionic acid (i-fatty acid yemvelo emfushane) ezilwaneni, okubandakanya ukusetshenziswa kwamandla okuvamile. Inobuthi obuphansi kakhulu futhi isetshenziswa kabanzi ezinkukhu, ezingulubeni, ezifuyweni ezidla inyama, nokuningi.
• Ukuzinza Okuhle: Ngokungafani ne-propionic acid, i-calcium propionate ayiboli, kulula ukuyigcina, futhi ixutshwe ngokulinganayo.

Izicelo

• Ivame ukusetshenziswa ezilwaneni ezifuywayo, ezinkukhu, ezifuyweni zasemanzini, kanye nasekudleni kwezilwane ezifuywayo. Isilinganiso esinconywayo ngokuvamile singu-0.1%–0.3% (lungisa ngokusekelwe kumswakama wokudla kanye nezimo zokugcina).
• Ekudleni kwezilwane ezelusayo, kusebenza futhi njengomthombo wamandla, okhuthaza ukukhula kwamagciwane e-rumen.

Izinyathelo zokuzivikela

• Amanani amaningi kakhulu angathinta kancane ukunambitheka (ukunambitheka okumuncu okuncane), yize kungaphansi kwe-propionic acid.
• Qinisekisa ukuthi uxuba ngendlela efanayo ukuze ugweme ukugxila okuphezulu endaweni ethile.

Inombolo ye-CAS: 65-85-0

Ifomula yama-molecule:C7H6O2

Ukubukeka：Impuphu yekristalu emhlophe

Ukuhlolwa: 99%

I-Benzoic Acid kuzinhlelo zokusebenza zokuphakelayo

Imisebenzi

• I-Broad-Spectrum Antimicrobial: Ivimbela amabhaktheriya (isb.,I-Salmonella,I-E. coli) kanye nezikhunta, kanye nokusebenza kahle okuthuthukisiwe ezindaweni ezine-asidi (okungcono kakhulu ku-pH <4.5).
• Ukukhuthazwa Kokukhula: Ekudleni kwezingulube (ikakhulukazi amaphuphu), kunciphisa i-pH yamathumbu, kucindezela amabhaktheriya ayingozi, kuthuthukisa ukumuncwa kwezakhamzimba, futhi kukhulisa ukukhuluphala kwansuku zonke.
• Ukwakheka komzimba: Kuhlanganiswe ne-glycine esibindini ukuze kwakheke i-hippuric acid yokukhipha. Imithamo eminingi ingase yandise umthwalo wesibindi/wezinso.

Izicelo

• Isetshenziswa kakhulu ezingulubeni (ikakhulukazi ezingulubeni ezincane) kanye nokudla kwezinkukhu. Isilinganiso esivunyelwe yi-EU singu-0.5%–1% (njenge-benzoic acid).
• Imiphumela yokusebenzisana uma ihlanganiswa nama-propionate (isb., i-calcium propionate) ukuze kuthuthukiswe ukuvinjelwa kwesikhunta.

Izinyathelo zokuzivikela

• Imikhawulo Eqinile Yomthamo: Ukusetshenziswa kwe-cap kwezinye izifunda (isb., imithethonqubo yokwengeza ukudla yaseShayina ikhawulela ku-≤0.1% ekudleni kwezingulube ezincane).
• Ukusebenza Okuxhomeke ku-pH: Akusebenzi kahle ekudleni okungathathi hlangothi/kwe-alkaline; kuvame ukuhlotshaniswa nezinto ezifaka i-acid.
• Izingozi Zesikhathi Eside: Imithamo ephezulu ingaphazamisa ibhalansi ye-microbiota yamathumbu.

Isifinyezo Sokuqhathanisa Namasu Okuhlanganisa

Amanothi Okulawula

• IShayina: AbalandeliIziqondiso Zokuphepha Kokwengezwa Kokuphakelayo—i-benzoic acid inqunyelwe ngokuphelele (isib., ≤0.1% kumachwane ezingulube), kuyilapho i-calcium propionate ingenawo umkhawulo oqinile ophezulu.
• I-EU: Ivumela i-benzoic acid ekudleni kwezingulube (≤0.5–1%); i-calcium propionate ivunyelwe kabanzi.
• Umkhuba: Abanye abakhiqizi bakhetha ezinye izindlela eziphephile (isb., i-sodium diacetate, i-potassium sorbate) kune-benzoic acid.

Izinto Ezibalulekile Okufanele Uzicabangele

1. Ukulawula Isikhunta: I-calcium propionate iphephile futhi isebenziseka kalula ekudleni okuningi.
2. Ukulawula Nokukhula Kwamagciwane: I-Benzoic acid iphumelela kakhulu ekudleni kwezingulube kodwa idinga isilinganiso esiqinile.
3. Isu Elihle Kakhulu: Ukuhlanganisa kokubili (noma nezinye izithasiselo) kulinganisela ukuvimbela isikhunta, ukusebenza kwamagciwane, kanye nokusebenza kahle kwezindleko.
