I-1.Isakhiwo se-potassium sorbate I-Potassium sorbate itholakala ngokusabela kwe-sorbate nge-potassium carbonate noma i-potassium hydroxide, futhi ukwakheka kwe-sorbate kufana ne-molecule encane ehlanganisiwe yama-fatty acids.
Isakhiwo esihlanganisiwe sama-fatty acids ngu-ch = ch-ch =CH-, futhi lesi sakhiwo esiqhubekayo se-carbon-carbon double bond (-C=C-) asizinzile kakhulu futhi siguqulwa kalula sibe yi-carbon dioxide namanzi emzimbeni womuntu, okubeka isisekelo sokuphepha kwe-potassium sorbate.
Ifomula yamakhemikhali ye-potassium sorbate ithi: CH3-CH=CH-CH=CH-COOK

2.Izici ze-potassium sorbate ne-potassium sorbate zinezakhiwo ezifanayo zokulwa nokubola, kodwa isakhiwo se-sorbate sifana nama-fatty acids, ukuncibilika emanzini kuvamile, okwenziwe nge-potassium sorbate, kungancibilika kangcono emanzini.
I-Potassium sorbate iyizinhlayiya ezimhlophe noma ezimhlophe noma impushana, ayinaphunga noma inephunga elincane, azinzile ekukhanyeni nasekushiseni.
Ngenxa yokuthi i-potassium sorbate iqukethe ama-double bond amabili ahlanganiswe ne-unsaturated conjugated, kulula ukwenza i-oxidize, ikakhulukazi izibopho ezimbili ezikude neqembu le-carboxyl (-COOH) kulula uku-oxidize, futhi i-potassium sorbate ene-oxidized izoba mnyama.

3.Kusuka esakhiweni se-potassium sorbate, isakhiwo sayo esiyinhloko yi-molecule encane ehlanganisiwe ye-fatty acid, eguqulwa kalula ibe yi-carbon dioxide namanzi emzimbeni womuntu, ngakho iphephile.
IKomidi Lochwepheshe Lezithako Zokudla (JECFA), elisungulwe ngokuhlanganyela yiNhlangano Yezempilo Yomhlaba (i-WHO) kanye neNhlangano Yezokudla Nezolimo yeNhlangano Yezizwe Ezihlangene (i-FAO), lenze ukuhlolwa okuningana kokuphepha kwe-potassium sorbate, futhi imiphumela ikhombisa ukuthi i-potassium sorbate iphephile ukusetshenziswa ngemithamo ejwayelekile. I-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) nazo zibheka i-potassium sorbate njengesithako sokudla esiphephile.
Ngokusho kwedatha yamanje yocwaningo lwesayensi, i-potassium sorbate ayifakwanga ohlwini njenge-carcinogen eyinhloko. I-International Agency for Research on Cancer (IARC) ihlukanisa i-potassium sorbate njengeleveli 3, okusho ukuthi ubufakazi obutholakalayo abanele ukuyibheka njenge-carcinogenic kubantu.
