Njirimara kemịkalụ:

Acetic acid, CH3COOH, bụ mmiri mmiri na-enweghị agba, na-agbanwe agbanwe na ọnọdụ okpomọkụ.Ngwakọta dị ọcha, glacial acetic acid, ji aha ya na ọdịdị kristal dị ka ice na 15.6ºC.Dị ka a na-enyekarị, acetic acid bụ ngwọta mmiri 6 N (ihe dịka 36%) ma ọ bụ ngwọta 1 N (ihe dịka 6%).A na-eji ntụ ntụ ndị a ma ọ bụ ndị ọzọ na-agbakwunye acetic acid kwesịrị ekwesị na nri.Acetic acid bụ njirimara acid nke mmanya, ntinye ya sitere na 3.5 ruo 5.6%.Acetic acid na acetates dị n'ọtụtụ osisi na anụ ahụ anụmanụ n'obere ntakịrị mana enwere ike ịchọpụta.Ha bụ ndị etiti metabolic nkịtị, nke ụdị nje bacteria dị ka acetobacter na-emepụta ma nwee ike mejupụta ya kpamkpam site na carbon dioxide site na microorganisms dị ka Clostridium thermoaceticum.Oke ahụ na-etolite acetate na ọnụego 1% nke ịdị arọ ahụ ya kwa ụbọchị.

Dị ka a colorless mmiri mmiri na ike, pungent, àgwà mmanya na-esi ísì, ọ bara uru na bọta, cheese, mkpụrụ vaịn na mkpụrụ flavors.A na-eji obere acetic acid dị ọcha dị ka nke a na nri, n'agbanyeghị na FDA na-ekewa ya dị ka ihe GRAS.N'ihi nke a, enwere ike were ya n'ọrụ na ngwaahịa na-adịghị ekpuchiri ya na nkọwapụta na ụkpụrụ nke njirimara.Acetic acid bụ akụkụ bụ isi nke mmanya na pyroligneous acid.N'ụdị mmanya vine, ihe karịrị nde lb 27 ka etinyere na nri na 1986, na-eji ihe dị ka nha nhata dị ka acidulants na ndị na-esi ísì ụtọ.N'ezie, acetic acid (dị ka mmanya) bụ otu n'ime ndị na-esi ísì ụtọ mbụ.A na-eji mmanya mmanya na-aba n'anya na-akwadebe salad mgbakwasa na Mayonezi, utoojoo na ụtọ pickles na ọtụtụ sauces na catsups.A na-ejikwa ha na-agwọ anụ nakwa n'ịkụnye akwụkwọ nri ụfọdụ.N'imepụta Mayonezi, mgbakwunye nke akụkụ acetic acid (mmanya) na nnu ma ọ bụ nkochi ime akwa na-ebelata okpomọkụ nke Salmonella.Ngwakọta mmiri na-ejikọta sausaji na-agụnyekarị acetic acid ma ọ bụ nnu sodium ya, ebe a na-eji calcium acetate chekwaa ọdịdị nke sliced ​​​​, akwụkwọ nri mkpọ.
