Aia ma lalo kahi hoʻolauna pōkole e pili ana i nā hana hana, nā ʻano a me ka loiloi i kuhikuhi ʻia o nā preservatives like ʻole.
1.ʻO ke ʻano holoʻokoʻa o ka hananā mea mālama
ʻO ka preservative nā mea kemika nui e kōkua i ka pepehi ʻana a i ʻole ke kāohi ʻana i nā hana o nā microorganisms i nā mea hoʻonaninani a me ka mālama ʻana i ka maikaʻi holoʻokoʻa o nā mea hoʻonaninani i kahi manawa lōʻihi.
Eia nō naʻe, pono e hoʻomaopopo ʻia ʻaʻole he bactericide nā preservatives 鈥 ʻaʻohe hopena bactericidal ikaika, a hana wale lākou i ka wā i hoʻohana ʻia i ka nui a i ʻole ke pili pono lākou me nā microorganism.
Kāohi nā preservatives i ka ulu ʻana o ka microbial i ka synthesis o nā enzyme metabolic koʻikoʻi a me ka pale ʻana i ka synthesis o nā protein i loko o nā ʻāpana cell koʻikoʻi a i ʻole ka synthesis o ka waikawa nucleic.
2.Nā mea e pili ana i nā hana o nā mea mālama
Nui nā kumu i ka hopena o nā preservatives.Aia lākou;
a.Ka hopena o ka pH
Hoʻololi ka hoʻololi i ka pH i ka hoʻoheheʻe ʻana o nā mea hoʻomalu waika organik, a pēlā e pili ai i ka pono holoʻokoʻa o nā preservatives.E laʻana, ma ka pH 4 a me ka pH 6, paʻa loa ka 2-bromo-2-nitro-1,3-propanediol.
b.Nā hopena o ka gel a me nā ʻāpana paʻa
ʻO Koalin, magnesium silicate, aluminika, a me nā mea ʻē aʻe, kekahi mau ʻāpana pauka i loaʻa i loko o kekahi mau mea hoʻonaninani, ka mea maʻamau e komo i ka preservative a no laila ke alakaʻi nei i ka nalowale o ka hana e ka preservative.Eia nō naʻe, ʻoi aku ka maikaʻi o kekahi i ka lawe ʻana i ka bacteria i loaʻa i ka preservative.Eia kekahi, ʻo ka hui pū ʻana o ka wai-soluble polymer gel a me ka preservative e hāʻawi i ka hōʻemi ʻana i ka neʻe ʻana o ke koena preservative i ka hoʻokumu ʻana i nā mea hoʻonaninani, a ua hōʻemi pū kēia i ka hopena o ka preservative.
c.Ka hopena hoʻoheheʻe ʻia o nā surfactants nonionic
ʻO ka solubilization o nā surfactants like ʻole e like me nā surfactants nonionic i loko o nā preservatives pili pū i ka hana holoʻokoʻa o nā preservatives.Eia nō naʻe, ʻike ʻia nā mea hoʻoheheʻe nonionic hiki ke hoʻoheheʻe ʻia i ka aila e like me HLB=3-6 he ʻoi aku ka nui o ka hiki ke hoʻopau ʻia ma nā preservatives i hoʻohālikelike ʻia me nā surfactants nonionic hiki ke hoʻoheheʻe wai me ka waiwai HLB kiʻekiʻe.
d.Ka hopena o ka pōʻino o ka mālama ʻana
Aia kekahi mau kumu ʻē aʻe e like me ka hoʻomehana ʻana, ka māmā a me nā mea ʻē aʻe, ke kuleana no ka hoʻohaʻahaʻa ʻana i nā preservatives, a laila e hoʻemi i kā lākou hopena antiseptic.ʻOi aku ka nui, ke alakaʻi nei kekahi o kēia mau hopena i kahi hopena biochemical ma muli o ka radiation sterilization a me ka disinfection.
e.Nā hana ʻē aʻe
Pēlā nō, ʻo nā mea ʻē aʻe e like me ke kū ʻana o nā mea ʻono a me nā mea chelating a me ka hāʻawi ʻana i nā preservatives i loko o ka ʻaila-wai ʻelua-phase e kōkua pū i ka hōʻemi ʻana i ka hana o nā preservatives i kekahi ʻano.
3.ʻO nā waiwai antiseptic o nā preservatives
Pono e noʻonoʻo ʻia nā waiwai antiseptic o nā preservatives.ʻO ka loaʻa ʻana o nā preservatives i loko o nā mea hoʻonaninani e hoʻonāukiuki maoli ia, aʻo ka hemahema o ka neʻe ʻana e hoʻopilikia i ka antiseptic.nā waiwai o nā mea mālama.ʻO ke ala maikaʻi loa e loiloi ai i kēia, ʻo ia ka hoʻohana ʻana i ka hoʻāʻo hoʻokūkū biological e pili ana i ka haʻahaʻa haʻahaʻa haʻahaʻa (MIC) a me ka hoʻāʻo inhibition zone.
ʻO ka hoʻāʻo pōʻai Bacteriostatic: Hoʻohana ʻia kēia hoʻāʻo e hoʻoholo i kēlā mau maʻi bacteria a me ka ʻōpala me ka hiki ke ulu wikiwiki loa ma hope o ka mahi ʻana ma kahi ʻano kūpono.Ma kahi i hoʻokuʻu ʻia ai kahi diski pepa kānana i hoʻopili ʻia me ka preservative ma waena o ka pā moʻomeheu moʻomeheu, e hana ʻia kahi pōʻai bacteriostatic a puni ma muli o ke komo ʻana o ka mea mālama.I ke ana ana i ke anawaena o ka poai bacteriostatic, hiki ke hoohana ia ma ke ano he iwilei no ka hoomaopopo ana i ka pono o ka preservative.
Me kēia, hiki ke ʻōlelo ʻia he maikaʻi loa ka pōʻai bacteriostatic e hoʻohana ana i ke ʻano pepa me ke anawaena >=1.0mm.Ua kapa ʻia ʻo MIC ma ke ʻano he haʻahaʻa haʻahaʻa o ka preservative hiki ke hoʻohui ʻia i loko o kahi ʻano e pale ai i ka ulu ʻana o ka microbial.Ma ia kūlana, he MIC liʻiliʻi, ʻoi aku ka ikaika o nā waiwai antimicrobial o ka preservative.
Hōʻike pinepine ʻia ka ikaika a i ʻole ka hopena o ka hana antimicrobial ma ke ʻano o ka haʻahaʻa haʻahaʻa haʻahaʻa (MIC).Ma ka hana ʻana pēlā, hoʻoholo ʻia kahi hana antimicrobial ikaika e ka waiwai liʻiliʻi o ka MIC.ʻOiai ʻaʻole hiki ke hoʻohana ʻia ka MIC e hoʻokaʻawale i waena o ka hana bactericidal a me ka hana bacteriostatic, ʻike ʻia nā surfactants i ka hopena bacteriostatic ma kahi haʻahaʻa haʻahaʻa a me ka hopena sterilization ma kahi kiʻekiʻe.
ʻO ka ʻoiaʻiʻo, i nā manawa like ʻole, hana kēia mau hana ʻelua i ka manawa like, a he mea paʻakikī kēia i ka hoʻokaʻawale ʻana.No kēia kumu, hāʻawi pinepine ʻia lākou i kahi inoa hui e like me ka disinfection antimicrobial a i ʻole disinfection wale nō.
