Li-preservativeke lintho tse thibelang kholo ea likokoana-hloko ka har'a sehlahisoa kapa ho thibela kholo ea likokoana-hloko tse sebetsanang le sehlahisoa.Li-preservative ha li thibele feela metabolism ea baktheria, hlobo le tomoso, empa hape li ama kholo ea tsona le ho ikatisa.Phello ea ho boloka ha ho etsoa e angoa ke lintlha tse fapa-fapaneng, tse kang mocheso oa tikoloho, PH ea tlhahiso, mokhoa oa ho etsa lihlahisoa, joalo-joalo, ho utloisisa lintlha tse sa tšoaneng ho thusa ho khetha le ho sebelisa li-preservative tse fapa-fapaneng.
Lintlha tse amang ts'ebetso ea li-preservatives tsa litlolo ke tse latelang:
A. mofuta oa li-preservatives
Sebopeho sa li-preservative ka boeona: ts'ebeliso ea mahloriso a li-preservatives le solubility ea phello e kholo ts'ebetsong.
1, Ka kakaretso, khatello ea maikutlo e phahame, e sebetsa haholoanyane;
2, Li-preservative tse qhibilihang ka metsing li na le ts'ebetso e ntle ea li-preservatives: likokoana-hloko hangata lia ata karolong ea metsi ea 'mele o entsoeng ka emulsified,' meleng oa emulsified, likokoana-hloko li tla khabisoa holim'a sebopeho sa metsi a oli kapa ho tsamaea karolong ea metsi.
Tšebelisano-'moho le metsoako e meng mofuteng: ho se sebetse ha li-preservative ke lintho tse ling.
B. Mokhoa oa tlhahiso ea sehlahisoa
Tikoloho ya tlhahiso;mocheso oa mokhoa oa tlhahiso;tatellano eo disebediswa di ekeletsoang ka yona
C. Sehlahisoa sa ho qetela
Likahare le liphutheloana tsa ka ntle tsa lihlahisoa li khetholla ka ho toba tikoloho ea bophelo ea likokoana-hloko ka litlolo.Lintho tsa tlhaho tsa tikoloho li kenyelletsa mocheso, tikolohopH boleng, khatello ea osmotic, mahlaseli, khatello e tsitsitseng;Likarolo tsa lik'hemik'hale li kenyelletsa mehloli ea metsi, limatlafatsi (mehloli ea C, N, P, S), oksijene, le lintlha tsa kholo ea manyolo.
