IGIKORWA MECHANISM_ UBWOKO N'ISUZUMA RY'INGENZI ZA PRESERVATIVES

Hano hepfo ni intangiriro ngufi yerekeye uburyo bwibikorwa, ubwoko kimwe nisuzuma ryerekanwe kubibungabunga bitandukanye

1.Uburyo rusange bwibikorwa byakubungabunga ibidukikije

Kuzigama ni ibintu byimiti ifasha kwica cyangwa guhagarika ibikorwa bya mikorobe mu kwisiga kimwe no gukomeza ubwiza rusange bwamavuta yo kwisiga mugihe kirekire.

Icyakora, twakagombye kumenya ko imiti igabanya ubukana atari bagiteri 鈥 nta ngaruka zikomeye ziterwa na bagiteri, kandi zikora gusa iyo zikoreshejwe ku bwinshi cyangwa iyo zihuye na mikorobe.

Kurinda ibintu bibuza gukura kwa mikorobe bibuza guhuza imisemburo ikomeye ya metabolike kimwe no kubuza guhuza poroteyine mu bice bigize ingirabuzimafatizo cyangwa guhuza aside nucleique.

2.Ibintu bigira ingaruka kubikorwa byo kubungabunga ibidukikije

Ibintu byinshi bigira uruhare mu ngaruka zo kwirinda.Harimo;

a.Ingaruka ya pH

Ihinduka rya pH rigira uruhare mu gusenyuka kwa aside irike, bityo bigira ingaruka kumikorere rusange.Fata nk'urugero, kuri pH 4 na pH 6, 2-bromo-2-nitro-1,3-propanediol irahagaze neza

b.Ingaruka za gel hamwe nuduce twinshi

Koalin, magnesium silikatike, aluminiyumu nibindi, nibice bimwe byifu biboneka mubintu bimwe na bimwe byo kwisiga, mubisanzwe bikurura imiti igabanya ubukana bityo bigatuma habaho gutakaza ibikorwa byakozwe na conservateur.Nyamara, zimwe na zimwe zifite akamaro mu gukuramo bagiteri ziboneka mu kubungabunga.Nanone, guhuza amazi ya elegitoroniki ya polymer hamwe no kubungabunga ibidukikije bigira uruhare mu kugabanya kwibumbira hamwe kw’ibisigisigi bisigara mu kwisiga, kandi ibyo nabyo byagabanije ingaruka zo kubungabunga ibidukikije.

c.Ingaruka ya solubilisation ya nonionic surfactants

Solubilisation ya surfactants zitandukanye nka nonionic surfactants muri preservateurs nazo zigira ingaruka mubikorwa rusange byo kubungabunga ibidukikije.Nyamara, amavuta-soluble nonionic surfactants nka HLB = 3-6 azwiho kuba afite ubushobozi buke bwo gukuraho imiti igabanya ubukana ugereranije n’amazi adashonga ya nonionic surfactants afite agaciro ka HLB.

d.Ingaruka zo kwangirika

Hariho ibindi bintu nko gushyushya, urumuri nibindi, bifite inshingano zo gutera kwangirika kwimiti igabanya ubukana, bityo bigatuma igabanuka ryingaruka zabo.Ibirenzeho, zimwe murizo ngaruka zitera reaction ya biohimiki biturutse kumirasire no kwanduza.

e.Indi mirimo

Mu buryo nk'ubwo, ibindi bintu nko kuba hari flavours hamwe na chelating agent no gukwirakwiza imiti igabanya ubukana mumazi-mazi ibyiciro bibiri nabyo bizagira uruhare mukugabanya ibikorwa byabashinzwe kubungabunga ibidukikije kurwego runaka.

3.Imiti igabanya ubukana

Imiti igabanya ubukana ikwiye kubitekerezaho.Kugira imiti irinda ibintu kwisiga byanze bikunze bizatera uburakari, mugihe kubura kwibanda bizagira ingaruka kuri antisepticimiterere yo kubungabunga ibidukikije.Uburyo bwiza bwo gusuzuma ibi ni ugukoresha ikizamini cyibinyabuzima kirimo byibuze kwibanda kuri MIC (MIC) hamwe nikizamini cya zone kibuza

Ikizamini cya bacteriostatike: Iki kizamini gikoreshwa mukumenya izo bagiteri no kubumba hamwe nubushobozi bwo gukura vuba nyuma yo guhinga muburyo bukwiye.Mugihe aho impapuro zungurura disiki zatewe hamwe na preservateur zimanikwa hagati yisahani yo hagati yumuco, hazabaho uruziga rwa bacteriostatike rwakozwe hirya no hino kubera kwinjira kwa preservateur.Iyo upimye diameter yumuzingi wa bacteriostatike, irashobora gukoreshwa nka yardstick kugirango hamenyekane ingaruka zokwirinda.

Hamwe nibi, birashobora kuvugwa ko uruziga rwa bacteriostatike ukoresheje uburyo bwimpapuro hamwe na diameter> = 1.0mm ni byiza cyane.MIC ivugwa nkibintu byibuze byibandwaho bishobora kwongerwaho uburyo bwo kubuza mikorobe.Mubihe nkibi, MIC ntoya, niko imbaraga za mikorobe zirwanya ibintu.

Imbaraga cyangwa ingaruka zibikorwa bya mikorobe mubisanzwe bigaragarira muburyo bwo kwibandaho byibuze (MIC).Kubikora, ibikorwa bikomeye bya mikorobe bigenwa nagaciro gake ka MIC.Nubwo MIC idashobora gukoreshwa mu gutandukanya ibikorwa bya bagiteri na bacteriostatike, ibisanzwe bizwi ko bifite ingaruka za bacteriostatike ku gipimo gito na sterisizione yibitekerezo byinshi.

Nkukuri, mubihe bitandukanye, ibyo bikorwa byombi bibera icyarimwe, kandi ibyo bituma bigorana gutandukana.Kubera iyo mpamvu, mubisanzwe bahabwa izina rusange nka virusi yica mikorobe cyangwa kwanduza gusa.
