Hana nā mea mālama i ka waikona Benzoic ma luna o kā lākou mau molekala ?ole. He lipophilicity ikaika ka waika benzoic unresociated a hiki ke komo ma?alahi i nā ke?ena ma o nā membrane cell, ke ke?ake?a nei i ka permeability o nā membrane cell microbial e like me nā mold a me ka bacteria, ke ke?ake?a nei i ka absorption o nā waikawa amino e nā membrane cell. ?O nā molekala Benzoic acid e komo ana i nā pūnaewele e ho?okahe i ka alkali i mālama ?ia, e kāohi i ka hana o nā enzyme hanu i loko o nā cell microbial, a pēlā e pā?ani ai i kahi kuleana preservative.

?O ka waikawa Benzoic kahi lā?au antimicrobial ākea ākea i loa?a ka hopena maika?i i ka hū, ka po?i, a me kekahi mau bacteria. I loko o ka palena ki?eki?e i ?ae ?ia o ka ho?ohana ?ana, loa?a iā ia nā hopena pale i nā ?ano bacteria ma nā koina pH ma lalo o 4.5.

?O ka waikawa Sorbic a me ka potassium sorbate he ha?aha?a ha?aha?a ma mua o ka benzoic acid, ?oi aku ka maika?i o ka mālama ?ana ma mua o ka sodium benzoate, a ?oi aku ka palekana. ?O nā mea maika?i o ka benzoic acid a me ka sodium benzoate ko lākou kūpa?a i ka ea a me ke kumukū?ai ha?aha?a. Akā, i loko o kahi kūlana sila, pa?a loa ka waikawa sorbic a me ka potassium sorbate, me ka potassium sorbate me ka pa?a wela maika?i a me ka mahana decomposition a hiki i 270 ℃. Ma muli o ka li?ili?i o nā mea?ai i ho?ohui ?ia, ?a?ole ia e ho?onui nui i ke kumukū?ai o nā huahana ?i?o. No laila, nui nā ?āina i lawe mālie i ka sorbic acid a me ka potassium sorbate i mea pani no ka benzoic acid a me ka sodium benzoate.

Eia kekahi, he ha?aha?a ka ha?aha?a o ka waikawa benzoic ma lalo o nā kūlana acidic. Inā ho?oulu ?ole ?ia, hiki mai ka crystallization kūloko o ka benzoic acid, e alaka?i ana i nā mea ho?ohui nui i nā huahana kūloko. ?O ka waikawa Benzoic kekahi hopena kū'ē i ka calcium chloride, a me nā hopena like i ka sodium chloride, isobutyric acid, gluconic acid, cysteine ????salts, etc. No laila, ?a?ole ?ōlelo ?ia e ho?ohana i ka benzoic acid a me ka sodium benzoate ma ke ?ano he preservatives i ka hana ?ai.

?O ka ?oia?i?o, ?o ka ho?ohui ?ana i ka waikawa benzoic a me ka sodium benzoate ?a?ole ia he ala mālama no nā huahana ?i?o. ?O ka ho?ohana ?ana i nā preservatives kūlohelohe, e like me Nisin, chitosan, spice extract, etc., hiki ke ho?okō i nā hopena antibacterial a me ka mālama ?ana, ?o ia ho?i kahi kuhikuhi ho?omohala o ka ?oihana ?i?o. Hiki ke ho?okō ?ia ka mālama ?ana a me ka mālama ?ana i nā huahana ?i?o ma o ka ho?omaika?i ?ana i nā kūlana ka?ina hana, ho?onui i ka ho?opili ?ana i ka mea?ai, mālama wela a i ?ole irradiation sterilization o nā huahana, a me ka mālama ha?aha?a ha?aha?a. ?O ka hope loa, ?o ka mea nui ka ho?oikaika ?ana i ka mālama ma?ema?e a ho?emi i ka haumia mai ke kumu
