1/17

Acidul malic este un compus organic ce se gasete n mod natural n fructe ca mere, struguri,ananas, fructe de pdure etc.

A fost izolat pentru prima data din suc de mere n 1785, iar n 1787 a primit denumirea de acidmalic.

Acidul malic este un compus important ce crete nivelul de energie din organism i rezistena laefort fizic.

Ca aditiv se oine prin sintez c!imic saudin fructe. Cea mai mare parte a acidului malic prezent n alimente se oine prin sintez c!imicdin acidul maleic.

"#$% este folosit n industria alimentar ca acidifiant sau ca arom.

"ste folosit i ca supliment alimentar, mpreun cu magneziul, pentru tratarea ooselii cornice i afiromilagiei.

Efectele consumului de alimente ce conin acid malic (E296)Acidul malic este un acid mai puternic decat acidul citriciacidul lactici de aceea este folositpentru a da alimentelor un gust acru, intens. &in aceasta cauz alimentele ce l contin pot iritasistemul digestiv.

'n anumit tip de dulciuri produse n ('A )conin o cantitate mare de acid malic* prezint peamala+ avertismentul consumul e-cesiv poate irita cavitatea ucal.

Ca i ceilali doi acizi menionai anterior, acidul malic se gsete n foarte multe alimentedestinate copiilor, ceea ce duce la efecte negative mai puternice n cazul acestora )afeciunidigestive, distrugerea smalului dentar*.

"#$% poate produce i n cazul adultilor afeciuni digestive )crampe, alonare* i distrugereasmalului dentar dac acetia consum frecvent uturi sau / i dulciuri ce conin acid malic.

Atunci cand consumai suplimente ce conin acid malic este recomandat s o facei mpreun cuo cantitate suficient de ap. 0entru a primi toate informaiile necesare, nainte de ncepereatratamentului, consultai un medic specialist.

"#$% poate reduce tensiunea arterial i nu este recomandat persoanelor !ipotensive sau careurmeaz un tratament n scopul reducerii acesteia.

Consumul ndelungat de acid malic poate produce oezitate i sc!imarea oiceiuriloralimentare. u este recomandat sa consumai acid malic mpreun cu produse pentru slait dincauza efectelor opuse ale celor dou suplimente.
