Acetic acid, ch3cooh, ndi madzi opanda utoto, osasunthika patenthedwe. Mafuta oyera, glaic acid, amakhala ndi mawonekedwe ake ngati ayezi ngati 15,6 ° C. Monga momwe nthawi zambiri amaperekera, acetic acid ndi njira ya 6 n yam'madzi (pafupifupi 36%) kapena 1 n yankho lake (pafupifupi 6%). Izi kapena zina zimagwiritsidwa ntchito powonjezera kuchuluka kwa acetic acid ndi zakudya. Acetic acid ndi mawonekedwe a acid a viniga, kukhazikika kwake kuyambira 3.5 mpaka 5.6%. Acetic acid ndi maheki amapezeka muzomera zambiri komanso nyama zazing'ono zazing'ono koma zopepuka. Amakhala metabolic yapakatikati, imapangidwa ndi mtundu wamabakiteriteria monga acetobacter ndipo imatha kuphatikizidwa kwathunthu kuchokera ku kaboni dayobote ndi tizilombo tating'onoting'ono monga clostridium therbooker. Makoswe amakongoletsa pamlingo wa 1% ya thupi lake patsiku.

Monga madzi opanda utoto ndi fungo lamphamvu, la mtundu wa viniga, ndizothandiza batala, tchizi, mphesa ndi zipatso zonunkhira. Zocheperako kwambiri mwamphamvu kwambiri chifukwa izi zimagwiritsidwa ntchito mu zakudya, ngakhale zimawerengedwa ndi FDA ngati zida za gras. Zotsatira zake, zitha kugwira ntchito zopangidwa ndi zinthu zomwe sizinaphimbe ndi matanthauzidwe ake. Acetic acid ndiye gawo lalikulu la vivgars ndi Pylogneous acid. Mu mawonekedwe a viniga, oposa 27 miliyoni lb adawonjezeredwa ku chakudya mu 1986, ndi kuchuluka pafupifupi komwe kumagwiritsidwa ntchito ngati acidirants ndi onunkhira. M'malo mwake, acetic acid (monga viniga) inali imodzi mwazinthu zokopa kwambiri. Vicgiars amagwiritsidwa ntchito kwambiri pokonzekera kuvala saladi ndi mayonesi, wowawasa ndi masamba otsekemera komanso ma casups ambiri. Amagwiritsidwanso ntchito pochiritsa nyama komanso m'matanga a masamba ena. Popanga mayonesi, kuwonjezera gawo la acetic acid (viniga) kwa mchere- kapena shuga-yolk kumachepetsa kutentherera kwa Salmonl. Madzi akumanga madzi nthawi zambiri kuphatikiza acetic acid kapena mchere wake wa sodium, pomwe calcium acetate amagwiritsidwa ntchito kusunga mawonekedwe a masamba osenda, okazinga.

Ntchito:

1. Amagwiritsa ntchito kapangidwe kake ndi inks.

2. Amagwiritsidwa ntchito popanga zonunkhira.

3. Amagwiritsidwa ntchito mu bizinesi ya mphira ndi pulasitiki. Amagwiritsidwa ntchito ngati zosungunulira komanso zoyambira pa ma polima ambiri (monga pva, pet, etc.) mu mafakitale a mphira ndi mafilimu.

4. Amagwiritsidwa ntchito ngati chinthu choyambira utoto ndi zomata

5. Amagwiritsidwa ntchito mu makampani ogulitsa chakudya monga chowonjezera mu tchizi ndi msuzi komanso ngati chosungira.
