I-Benzoic acid i-preservatives isebenza kwiimolekyuli zabo ezingadibaniyo. I-Unresociated benzoic acid ine-lipophilicity eyomeleleyo kwaye inokungena ngokulula kwiiseli ngeenwebu zeseli, iphazamisana nokungena kwe-microbial cell membranes ezifana nokungunda kunye neebhaktheriya, ithintela ukufunxwa kwe-amino acids ngeenwebu zeseli. Iimolekyuli ze-Benzoic acid ezingena kwiiseli zi-acidify i-alkali egciniweyo, inqanda umsebenzi we-enzymes yokuphefumula kwiiseli ze-microbial, kwaye ngaloo ndlela idlala indima yokulondoloza.

I-Benzoic acid yi-agent ebanzi ye-antimicrobial enefuthe elihle kwi-yeast, i-mold, kunye nezinye iibhaktheriya. Ngaphakathi koluhlu oluvumelekileyo lokusetyenziswa, lunemiphumo yokuthintela kwiibhaktheriya ezahlukeneyo kumaxabiso e-pH angaphantsi kwe-4.5.

I-asidi ye-Sorbic kunye ne-potassium sorbate ine-toxicity ephantsi kune-benzoic acid, i-preservative effect engcono kune-sodium benzoate, kwaye ikhuselekile. Izibonelelo ze-benzoic acid kunye ne-sodium benzoate zizinzo lwabo emoyeni kunye neendleko eziphantsi. Kodwa kwimeko etywiniweyo, i-sorbic acid kunye ne-potassium sorbate nazo zizinzile kakhulu, kunye ne-potassium sorbate inozinzo oluhle lwe-thermal kunye nobushushu bokubola ukuya kuma-270 ℃. Ngenxa yexabiso elincinci lezongezo zokutya ezongeziweyo, azinyusi kakhulu iindleko zeemveliso zenyama. Ngoko ke, amazwe amaninzi aye amkela ngokuthe ngcembe i-sorbic acid kunye ne-potassium sorbate njengeendawo ze-benzoic acid kunye ne-sodium benzoate.

Ukongeza, i-benzoic acid ine-solubility ephantsi phantsi kweemeko ze-acidic. Ukuba ishukunyiswe ngokungalinganiyo, icrystallization yendawo ye-benzoic acid inokwenzeka, ekhokelela kwizongezo ezigqithisileyo kwiimveliso zasekhaya. I-Benzoic acid nayo inefuthe elichasayo kwi-calcium chloride, kunye nemiphumo efanayo kwi-sodium chloride, i-isobutyric acid, i-gluconic acid, i-cysteine ??salts, njl njl. Ukongeza i-benzoic acid inokubangela ukuba i-astringency ekudleni kwaye iphazamise incasa yeemveliso zenyama. Ngoko ke, akukhuthazwa ukuba kusetyenziswe i-benzoic acid kunye ne-sodium benzoate njengezigcini kwimveliso yenyama.

Enyanisweni, ukongeza i-benzoic acid kunye ne-sodium benzoate akuyona indlela yokulondoloza kwimveliso yenyama. Ukusetyenziswa kwezigcini zendalo, ezifana ne-Nisin, i-chitosan, i-spice extract, njl., inokuphinda ifezekise imiphumo ye-antibacterial kunye nokugcinwa kwayo, ekwalukhokelo lophuhliso loshishino lwenyama. Ukugcinwa kunye nokugcinwa kweemveliso zenyama kunokufezekiswa ngokuphucula iimeko zokucubungula, ukuphucula ukupakishwa kokutya, unyango lobushushu okanye i-irradiation sterilization yeemveliso, kunye nokugcinwa kobushushu obuphantsi. Ekugqibeleni, eyona nto ibalulekileyo kukuqinisa ulawulo lococeko kunye nokunciphisa ungcoliseko oluvela kumthombo
