I-Potassium Sorbate isetshenziswa kabanzi njengama-Preservatives emazweni amaningi
Isingeniso
Amakristalu ama-scaly amhlophe kuya kokuphuzi, i-crystalline powder, noma i-granular. Ayinaphunga noma inephunga elincane. Ukugcina isikhathi eside emoyeni, kulula ukumunca umswakama nokubola kwe-oxidative nokubala. Ukuminyana okuhlobene (d2025): 1.363. Iphuzu lokuncibilika 270 °c (ukubola). Incibilika emanzini (67.6g/100ml, 20 °C), 5% amanzi anosawoti (47.5g/100ml, izinga lokushisa legumbi), 25% amanzi anoshukela (5Chemicalbooklg/100ml, izinga lokushisa legumbi). Incibilika ku-propylene glycol (5.8g/100m1), i-ethanol (0.3g/100m1). Inani le-pH lika-1% wesisombululo esinamanzi ngu-7~8. Inethonya elinamandla lokuvimbela amagciwane abolayo kanye nesikhunta, futhi ngenxa yokuthi ubuthi buphansi kakhulu kunezinye izivimbelakuvunda, isibe isilondolozi esiyinhloko emhlabeni. Ngaphansi kwezimo ezine-acidic, inganikeza ukudlala okugcwele kumphumela we-antiseptic, futhi umphumela uphansi kakhulu uma ungathathi hlangothi
incazelo2
ukusetshenziswa
I-1) Isetshenziswa kakhulu njengesilondolozi embonini yokudla, inganweba impilo yeshalofu yokudla.
2) Inemiphumela emihle yokulwa namagciwane ngokumelene nesikhunta, amabhaktheriya akhiqiza i-aerobic spore, nama-bacterium angenayo igram, futhi imvubelo ayinabungozi.
3) Lo mkhiqizo ungaphinda uvimbele ukukhiqizwa kwe-aflatoxin futhi usetshenziselwe kabanzi ukuvimbela isikhunta nokugcina isinkwa, amakhekhe, isoso yesoya, imikhiqizo yesoya, ujamu, nokudla okusemathinini.
I-4) Kubalwa nge-propionic acid, inani eliphakeme le-calcium propionate elisetshenziswa emikhiqizweni ye-noodle emanzi (ama-noodle asikiwe, isikhumba se-Wonton) ngu-0.25g/kg; Ukusetshenziswa okuphezulu kwesinkwa, uviniga, isoso yesoya, amakhekhe, kanye nemikhiqizo yesoya ngu-2.5g/kg.
5) I-calcium propionate nayo isetshenziswa njengesilondolozi sokudla;
6) Ingasetshenziswa futhi ngezinjongo zokwelapha, ukwenza uketshezi, izimpushana, amafutha okugcoba, njll;
I-7) Ibuye ibe nomthelela omuhle ezifweni zesikhumba ezibangelwa isikhunta.
I-8) I-Calcium propionate nayo inomphumela wokuqinisa i-calcium, ngakho-ke ingasetshenziswa ukwengeza i-calcium ekudleni okufana nesinkwa.
9) I-Calcium propionate ingaphinda ivimbele ukukhiqizwa kwe-Bacillus subtilis ngesikhathi sokuvutshelwa kwenhlama. Isilinganiso esincane se-inhibitory concentration singu-0.01% ku-pH engu-5.0, 0.188% ku-pH engu-5.8, futhi i-pH efanele kufanele ibe ngaphansi kuka-5.5
