1.Imiterere ya potassium sorbate Potassium sorbate iboneka nigisubizo cya sorbate hamwe na karubone ya potasiyumu cyangwa hydroxide ya potasiyumu, kandi imiterere ya sorbate isa nkiya molekile nto ya conjugated fatty acide.
Imiterere ihujwe na acide ya acide ni -ch = ch-ch = CH-, kandi iyi mikorere ikomeza ya karubone-karubone ikomatanya (-C = C-) ntigihungabana cyane kandi byoroshye guhindurwamo dioxyde de carbone namazi mumubiri wumuntu, bikaba umusingi wumutekano wa sorbate ya potasiyumu.
Imiti yimiti ya potasiyumu sorbate ni: CH3-CH = CH-CH = CH-COOK

?

2.Ibiranga sorbate ya potasiyumu na potassium sorbate bifite imiterere imwe yo kurwanya ruswa, ariko imiterere ya sorbate isa na aside irike, gushonga mumazi ni rusange, bikozwe muri sorbate ya potasiyumu, birashobora gushonga neza mumazi.
Potasiyumu sorbate ni ibice byera cyangwa byera cyangwa ifu, impumuro nziza cyangwa impumuro nkeya, ihamye kumucyo nubushyuhe.
Kuberako potasiyumu sorbate irimo imigozi ibiri idahagije ya conjugated inshuro ebyiri, biroroshye okiside, cyane cyane imigozi ibiri iri kure yitsinda rya carboxyl (-COOH) byoroshye okiside, kandi sibate ya potasiyumu ya okiside izahinduka umwijima.

3.Ku miterere ya potasiyumu sorbate, imiterere yacyo nyamukuru ni molekile ntoya ya conjugated fatty acide, ihinduranya byoroshye muri dioxyde de carbone n'amazi mumubiri wumuntu, bityo bikaba bifite umutekano muke.
Komite y’impuguke ku nyongeramusaruro y’ibiribwa (JECFA), yashyizweho n’umuryango w’ubuzima ku isi (OMS) n’umuryango w’abibumbye ryita ku biribwa n’ubuhinzi (FAO), yakoze isuzuma ryinshi ry’umutekano wa potasiyumu, kandi ibisubizo byerekana ko sorbate ya potasiyumu ifite umutekano ikoreshwa ku kigero gisanzwe. Ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) n’ikigo cy’ibihugu by’Uburayi gishinzwe umutekano w’ibiribwa (EFSA) na bo babona ko sorbate ya potasiyumu ari inyongeramusaruro yizewe.
Dukurikije imibare yubushakashatsi bugezweho, potassium sorbate ntabwo yashyizwe kurutonde rwa kanseri yibanze. Ikigo mpuzamahanga gishinzwe ubushakashatsi kuri kanseri (IARC) gishyira mu mwanya wa potasiyumu sorbate nk'urwego rwa 3, bivuze ko ibimenyetso bihari bidahagije kugira ngo bibe ko ari kanseri ku bantu.
