1. Kapangidwe ka potassium sorbate Potaziyamu sorbate imapezeka ndi momwe sorbate ndi potaziyamu carbonate kapena potaziyamu hydroxide, ndipo mapangidwe a sorbate ndi ofanana ndi ang'onoang'ono a molekyulu conjugated mafuta acid.
Kapangidwe ka conjugated mafuta acids ndi -ch = ch-ch =CH-, ndipo mosalekeza carbon-carbon double bond dongosolo (-C = C-) ndi wosakhazikika ndipo mosavuta zimapukusidwa mu carbon dioxide ndi madzi mu thupi la munthu, amene amayika maziko a chitetezo cha potaziyamu sorbate.
Mankhwala a potassium sorbate ndi: CH3-CH=CH-CH=CH-COOK

?

2.Makhalidwe a potassium sorbate ndi potassium sorbate ali ndi zotsutsana ndi zowonongeka, koma mawonekedwe a sorbate ndi ofanana ndi mafuta acids, kusungunuka m'madzi kumakhala kofala, kopangidwa ndi potassium sorbate, kumatha kusungunuka bwino m'madzi.
Potaziyamu sorbate ndi tinthu zoyera kapena zoyera kapena ufa, zopanda fungo kapena zonunkhiza pang'ono, zokhazikika pakuwala komanso kutentha.
Chifukwa potaziyamu sorbate imakhala ndi ma bond awiri osapangidwa ndi unsaturated conjugated oxidize, makamaka ma bond awiri omwe ali kutali ndi gulu la carboxyl (-COOH) ndi oxidize, ndipo potassium oxidized sorbate imakhala yakuda.

3.Kuchokera ku mapangidwe a potassium sorbate, kapangidwe kake kakang'ono kamene kamakhala kamene kamakhala kamene kamapangidwa ndi mafuta a asidi, omwe amapangidwa mosavuta kukhala carbon dioxide ndi madzi m'thupi la munthu, choncho ndi otetezeka.
Komiti ya Katswiri pa Zakudya Zowonjezera (JECFA), yomwe idakhazikitsidwa ndi World Health Organisation (WHO) ndi Food and Agriculture Organisation ya United Nations (FAO), yachita zowunika zingapo zachitetezo cha potassium sorbate, ndipo zotsatira zake zikuwonetsa kuti potaziyamu sorbate ndi yotetezeka kugwiritsidwa ntchito pamilingo yokhazikika. Bungwe la US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA) amawonanso kuti potaziyamu sorbate ndi chakudya chotetezeka.
Malinga ndi kafukufuku waposachedwa wasayansi, potassium sorbate sinalembedwe ngati carcinogen yoyamba. Bungwe la International Agency for Research on Cancer (IARC) limayika potassium sorbate ngati mlingo 3, kutanthauza kuti umboni womwe ulipo ndi wosakwanira kuuganizira kuti ndi khansa kwa anthu.
