1.Isakhiwo se-potassium sorbate I-Potassium sorbate ifunyenwe ngokuphendula kwe-sorbate kunye ne-potassium carbonate okanye i-potassium hydroxide, kunye nesakhiwo se-sorbate sifana ne-molecule encinci i-conjugated fatty acids.
Isakhiwo esidibeneyo se-fatty acids -ch = ch-ch = CH-, kwaye le ngqungquthela eqhubekayo ye-carbon-carbon bond bond structure (-C = C-) ayizinzile kwaye i-metabolized kalula kwi-carbon dioxide kunye namanzi emzimbeni womntu, obeka isiseko sokhuseleko lwe-potassium sorbate.
Ifomula yeekhemikhali ze-potassium sorbate yile: CH3-CH=CH-CH=CH-COOK

I-2.Iimpawu ze-potassium sorbate kunye ne-potassium sorbate zinezixhobo ezifanayo zokulwa ne-corrosion, kodwa isakhiwo se-sorbate sifana ne-fatty acids, i-solubility emanzini ngokubanzi, eyenziwe nge-potassium sorbate, inokuchithwa kangcono emanzini.
I-Potassium sorbate ngamasuntswana amhlophe okanye amhlophe okanye umgubo, ayinavumba okanye inevumba elincinane, izinzile ekukhanyeni nasekufudumeni.
Ngenxa yokuba i-potassium sorbate iqulethe iibhondi ezimbini ze-conjugated ezi-unsaturated, kulula uku-oxidize, ngakumbi iibhondi eziphindwe kabini ezikude neqela le-carboxyl (-COOH) zilula uku-oxidize, kwaye i-potassium sorbate ene-oxidized iya kuba mnyama.

3.Ukususela kwisakhiwo se-potassium sorbate, isakhiwo sayo esiphambili yi-molecule encinci ye-conjugated fatty acid structure, eyenziwa ngokulula kwi-carbon dioxide kunye namanzi emzimbeni womntu, ngoko ikhuselekile.
IKomiti yeeNgcali kwiZongezo zokutya (JECFA), ehlanganiswe nguMbutho wezeMpilo weHlabathi (i-WHO) kunye ne-Food and Agriculture Organisation yeZizwe eziManyeneyo (i-FAO), iqhube iimvavanyo ezininzi zokhuseleko lwe-potassium sorbate, kwaye iziphumo zibonisa ukuba i-potassium sorbate ikhuselekile ukusebenzisa kwiidosi eziqhelekileyo. I-US Food and Drug Administration (FDA) kunye ne-European Food Safety Authority (EFSA) iphinda ithathele ingqalelo i-potassium sorbate njengento ekhuselekileyo yokutya.
Ngokutsho kwedatha yophando lwenzululwazi yangoku, i-potassium sorbate ayidweliswanga njenge-carcinogen ephambili. I-Arhente yamazwe ngamazwe yoPhando lweCancer (IARC) ichaza i-potassium sorbate njengenqanaba le-3, oku kuthetha ukuba ubungqina obukhoyo abunelanga ukuyiqwalasela i-carcinogenic kubantu.
