Acetic acid, CH3COOH, ndi madzi opanda mtundu, osasunthika pa kutentha kozungulira.Gulu loyera, glacial acetic acid, limadziwika chifukwa cha mawonekedwe ake ngati ayezi pa 15.6 ° C.Monga momwe zimaperekedwa, asidi acetic ndi 6 N amadzimadzi yothetsera (pafupifupi 36%) kapena 1 N yankho (pafupifupi 6%).Mankhwalawa amagwiritsidwa ntchito powonjezera asidi woyenerera ku zakudya.Acetic asidi ndi khalidwe asidi viniga, ndende yake kuyambira 3.5 mpaka 5.6%.Acetic acid ndi acetates amapezeka muzomera zambiri ndi nyama zanyama zochepa koma zowoneka.Izi ndizomwe zimapangidwira kagayidwe kachakudya, amapangidwa ndi mitundu ya mabakiteriya monga Acetobacter ndipo amatha kupangidwa kwathunthu kuchokera ku carbon dioxide ndi tizilombo toyambitsa matenda monga Clostridium thermoaceticum.Makoswe amapanga acetate pamlingo wa 1% wa kulemera kwa thupi lake patsiku.

Monga colorless madzi ndi amphamvu, pungent, khalidwe vinyo wosasa fungo, ndi zothandiza batala, tchizi, mphesa ndi zipatso oonetsera.Acetic acid ochepa kwambiri monga choncho amagwiritsidwa ntchito muzakudya, ngakhale amagawidwa ndi FDA ngati zinthu za GRAS.Chifukwa chake, zitha kugwiritsidwa ntchito pazinthu zomwe sizikuphatikizidwa ndi Mafotokozedwe ndi Miyezo ya Identity.Acetic acid ndiye chigawo chachikulu cha vinegars ndi pyroligneous acid.Mu mawonekedwe a viniga, oposa 27 miliyoni lb anawonjezeredwa ku chakudya mu 1986, ndi pafupifupi ofanana ndalama ntchito ngati acidulants ndi flavoring agents.M'malo mwake, asidi acetic (monga viniga) anali amodzi mwazinthu zokometsera zakale kwambiri.Viniga amagwiritsidwa ntchito kwambiri pokonzekera saladi kuvala ndi mayonesi, pickles wowawasa ndi okoma ndi sauces ambiri ndi makatsups.Amagwiritsidwanso ntchito pochiritsa nyama ndi kuika m’zitini zamasamba.Popanga mayonesi, kuwonjezera gawo la acetic acid (vinyo wosasa) ku mchere kapena shuga-yolk kumachepetsa kukana kwa kutentha kwa Salmonella.Zomangamanga zamadzi za soseji nthawi zambiri zimakhala ndi acetic acid kapena mchere wake wa sodium, pomwe calcium acetate imagwiritsidwa ntchito kusunga mawonekedwe a masamba odulidwa, zamzitini.
