1. ?O ke ?ano o ka potassium sorbate Loa?a ka potassium sorbate ma ka hopena o ka sorbate me ka potassium carbonate a i ?ole ka potassium hydroxide, a ua like ke ?ano o ka sorbate me nā mole li?ili?i conjugated fatty acids.
?O ka ho?ohui ?ia o nā ?akika momona ?o -ch = ch-ch =CH-, a ?o kēia ?ano ho?opa?a pa?a pālua carbon-carbon (-C=C-) ?a?ole pa?a a ma?alahi ho?i e ho?ololi ?ia i carbon dioxide a me ka wai i loko o ke kino o ke kanaka, kahi e ho?okumu ai i ke kumu no ka palekana o ka potassium sorbate.
?O ke kumu kemika o ka potassium sorbate: CH3-CH=CH-CH=CH-COOK

2.Characteristics o ka potassium sorbate a me ka potassium sorbate loa?a nā waiwai anti-corrosion like, akā ?o ke ?ano o ka sorbate e like me nā momona momona, ?oi aku ka nui o ka solubility i ka wai, i hana ?ia me ka potassium sorbate, hiki ke ho?ohehe?e maika?i ?ia i ka wai.
?O ka potassium sorbate he mau mea ke?oke?o a ke?oke?o a pauka paha, ?a?ohe ?ala a ?ala iki paha, pa?a i ka māmā a me ka wela.
No ka mea, aia i loko o ka potassium sorbate ?elua mau mea pa?a pa?a ?ole i ho?ohui ?ia, ua ma?alahi ke ho?ohehe?e ?ia, ?oi aku ka ma?alahi o nā pa?a pālua ma kahi mamao loa mai ka pū?ulu carboxyl (-COOH), a ?oi aku ka pō?ele?ele o ka potassium sorbate.

3.Mai ke ?ano o ka potassium sorbate, ?o kona ?ano nui he ?ano li?ili?i li?ili?i conjugated fatty acid structure, i ma?alahi ka metabolized i carbon dioxide a me ka wai i loko o ke kino o ke kanaka, no laila ua palekana.
?O ke Kōmike Kūkākūkā o nā mea?ai mea?ai (JECFA), i ho?okumu pū ?ia e ka World Health Organization (WHO) a me ka Food and Agriculture Organization o United Nations (FAO), ua hana i kekahi mau loiloi palekana o ka potassium sorbate, a ua hō?ike nā hopena i ka palekana o ka potassium sorbate e ho?ohana i nā kumu ma?amau. ?O ka US Food and Drug Administration (FDA) a me ka European Food Safety Authority (EFSA) no?ono?o pū kekahi i ka potassium sorbate i mea ho?ohui mea?ai palekana.
Wahi a ka ?ikepili noi?i ?epekema o kēia manawa, ?a?ole i helu ?ia ka potassium sorbate ma ke ?ano he carcinogen mua. Ho?oka?awale ka International Agency for Research on Cancer (IARC) i ka potassium sorbate ma ke ?ano he 3, ?o ia ho?i, ?a?ole lawa nā hō?ike i loa?a e no?ono?o ai he carcinogenic i ke kanaka.
