Ukusetshenziswa Kwemikhiqizo
Mayelana nezithako zokudla, isetshenziswa kakhulu eziphuzweni eziqabulayo kanye nemikhiqizo efakwe emanzini anosawoti njengeziphuzo ezine-carbonated, iziphuzo zejusi yezithelo, neziphuzo ze-lactic acid. Isidingo sayo singaphansi kwezinguquko zesimo sezulu sesizini. I-Citric acid yenza cishe u-2/3 wengqikithi yokusetshenziswa kwama-agent omuncu.
1. Ukwengeza i-citric acid esithelweni esisemathinini kungagcina noma kuthuthukise ukunambitheka kwesithelo, kwandise i-asidi (kwehlise inani le-pH) yezinye izithelo ezine-asidi ephansi uma zigcinwe emathini, kwenze buthaka ukumelana nokushisa kwama-microorganisms futhi kuvimbele ukukhula kwazo, futhi vimbela i-acidity ephansi. Ukwanda nokulimala kwamagciwane kuvame ukwenzeka esithelweni esisemathinini.
2. Ukwengeza i-citric acid kuswidi njenge-agent emuncu kulula ukuvumelanisa nokunambitheka kwezithelo. Ukusetshenziswa kwe-citric acid ekudleni kwejeli okufana nejamu kanye nejeli kunganciphisa ngempumelelo ukukhokhiswa okungalungile kwe-pectin, ukuze izibopho ze-hydrogen phakathi kwama-molecule e-pectin zikwazi ukugeliswa.
3. Lapho ucubungula imifino ekheniwe, eminye imifino ine-alkaline, futhi ukusebenzisa i-citric acid njengomlawuli we-pH ayikwazi ukudlala indima yesinongo kuphela, kodwa futhi igcine ikhwalithi yayo.
4. I-Citric acid inezici ze-chelation kanye nokulungiswa kwe-pH, ukuze ikhulise ukusebenza kwe-antioxidant, ivimbele umsebenzi we-enzyme futhi yandise impilo yeshalofu yokudla ekucubunguleni ukudla okufriziwe okusheshayo.
Iphakheji Nesitoreji
Iphakheji:ifakwe esikhwameni esilukiwe sepulasitiki esingangeni emanzini, 25kg isikhwama ngasinye noma njengezidingo zakho.
Phawula: Ukwakheka kwekhemikhali nosayizi kungenziwa ngokugcwele ngezidingo zamakhasimende
Isitoreji:
Ihlukaniswe nama-oxidants aqinile, izisekelo eziqinile, ama-nitrate ensimbi nezinsimbi. Eyomile.I-crystalline citric acid, i-anhydrous, ingagcinwa efomini elomile ngaphandle kobunzima, nakuba izimo zomswakama ophezulu kanye nezinga lokushisa eliphakeme kufanele zigwenywe ukuze kuvinjelwe ukugoqa. Isitoreji kufanele sibe seziqukathi eziqinile ukuvimbela ukuchayeka emoyeni onomswakama. Ama-granulations amaningana atholakala ngokuthengisa ngosayizi wezinhlayiyana ezinkulu ezinokuthambekela okuncane ekubambeni.
Ukuvikela Ukuphepha
Izinyathelo zokuphepha zokuphatha okuphephile
AKUKHO amalangabi avulekile. Isistimu evaliwe, okokusebenza kukagesi okungaqhumi uthuli nokukhanyisa. Vimbela ukufakwa kothuli. Ukuphatha endaweni enomoya omuhle. Gqoka izingubo ezifanele zokuzivikela. Gwema ukuthinta isikhumba namehlo. Gwema ukwakheka kothuli nama-aerosol. Sebenzisa amathuluzi angashiyi izinhlansi. Vimbela umlilo obangelwa umusi wokukhipha i-electrostatic.
