ʻO ka ʻakika Acetic, CH3COOH, he wai waihoʻoluʻu ʻole i nā mahana ambient. ʻO ka pūhui maʻemaʻe, glacial acetic acid, nona ka inoa i kona ʻano aniani like me ka hau ma 15.6°C. E like me ka mea maʻamau, ʻo ka ʻakika acetic he 6 N ka hopena wai (ma kahi o 36%) a i ʻole ka hopena 1 N (ma kahi o 6%). Hoʻohana ʻia kēia a i ʻole nā ​​​​mea hoʻoheheʻe ʻē aʻe i ka hoʻohui ʻana i ka nui o ka acetic acid i nā meaʻai. ʻO ka waikawa Acetic ka waika maʻamau o ka vīnega, ʻo kona ʻike mai 3.5 a 5.6%. Aia ka Acetic acid a me ka acetates i ka hapa nui o nā mea kanu a me nā ʻiʻo holoholona i ka liʻiliʻi akā hiki ke ʻike ʻia. ʻO lākou nā mea maʻamau metabolic intermediates, i hana ʻia e nā ʻano bacteria e like me Acetobacter a hiki ke synthesized piha mai carbon dioxide e nā microorganism e like me Clostridium thermoaceticum. Hoʻokumu ka ʻiole i ka acetate ma ka helu o 1% o kona kaumaha kino i kēlā me kēia lā.

Ma ke ʻano he wai kala ʻole me ka ʻala ikaika a me ke ʻano o ka vīnega, pono ia i ka pata, ka paʻakai, ka hua waina a me nā ʻono hua. ʻAʻole liʻiliʻi ka ʻakika acetic maʻemaʻe e like me ia i hoʻohana ʻia i nā meaʻai, ʻoiai ua helu ʻia e FDA ma ke ʻano he mea GRAS. No laila, hiki ke hoʻohana ʻia i nā huahana i uhi ʻole ʻia e nā wehewehe a me nā kūlana o ka ʻike. ʻO ka waikawa Acetic ka mea nui o ka vīnega a me ka waikawa pyroligneous. Ma ke ʻano o ka vīneka, ʻoi aku ma mua o 27 miliona lb i hoʻohui ʻia i ka meaʻai i ka makahiki 1986, me ka nui o nā mea like i hoʻohana ʻia e like me nā acidulants a me nā mea ʻono. ʻO ka ʻoiaʻiʻo, ʻo ka acetic acid (e like me ka vīnega) kekahi o nā mea ʻono mua loa. Hoʻohana nui ʻia ka vinega i ka hoʻomākaukau ʻana i ka ʻaʻahu salakeke a me ka mayonnaise, nā pīkī ʻawaʻawa a me ka ʻono a me nā ʻuala he nui a me nā pōpoki. Hoʻohana ʻia lākou i ka hoʻōla ʻana i ka ʻiʻo a me ke kīʻaha ʻana i kekahi mau mea kanu. I ka hana ʻana i ka mayonnaise, ʻo ka hoʻohui ʻana o kahi ʻāpana o ka acetic acid (vinegar) i ka paʻakai a i ʻole ke kō-yolk e hoʻemi i ka pale wela o Salmonella. Hoʻokomo pinepine ʻia ka ʻakika acetic a i ʻole ka paʻakai sodium i ka hui paʻa wai o nā sausages, ʻoiai hoʻohana ʻia ka calcium acetate no ka mālama ʻana i ke ʻano o nā mea kanu i kālai ʻia.
