Na życzenie klienta udostępniamy atest jakości.

Askorbinian sodu, znany również jako kwas askorbinowy, jest organicznym związkiem chemicznym, który pełni rolę w organizmach żywych, w tym również ludzi. Jest to sól sodowa kwasu askorbinowego, czyli witaminy C. Askorbinian sodu często jest stosowany jako dodatek do żywności, ze względu na swoje właściwości antyutleniające, które pomagają w zapobieganiu utlenianiu się składników odżywczych w żywności, a także w utrzymaniu jej świeżości i koloru. Może być stosowany także w przemyśle farmaceutycznym i kosmetycznym, gdzie jego właściwości antyutleniające są wykorzystywane do zachowania stabilności produktów. Ponadto, askorbinian sodu może być wykorzystywany w procesach przemysłowych, np. jako substancja redukująca lub katalizator reakcji chemicznych.

Oto przykładowe zastosowanie askorbinianu sodu:

Produkcja soków owocowych: Askorbinian sodu jest dodawany do soków owocowych jako środek przeciwutleniający, który pomaga w zapobieganiu utlenianiu się witaminy C oraz innych składników odżywczych w soku. Dzięki temu sok może zachować swój świeży smak, kolor i wartość odżywczą przez dłuższy czas, co jest istotne w przypadku produktów sprzedawanych na dużą skalę oraz tych, które są przechowywane przez dłuższy czas przed spożyciem. Dodatek askorbinianu sodu pomaga również w zwiększeniu stabilności soku i zachowaniu jego jakości, co jest kluczowe dla producentów soków owocowych.
