Overview

E574 - Gluconic acid

Gluconic acid (E574) is a mild, clean-tasting organic acid made by oxidizing glucose, often through fermentation. Food makers use it to control acidity and to bind trace metals that can dull flavor or color in foods and drinks.

E578 - calcium gluconate

Calcium gluconate (E578) is a calcium salt of gluconic acid used in food as a stabilizer and sequestrant, which means it ties up trace metals that can spoil taste, color, and texture. It is also used to add a gentle boost of calcium without changing flavor very much.

Popular questions

Is gluconic acid gluten free?
Yes. Gluconic acid (E574) is made from glucose and contains no wheat proteins, so it is gluten‑free by composition.
Can dogs have gluconic acid?
In the small amounts found in pet-safe foods or dental products, gluconic acid is generally fine for dogs; avoid giving concentrated solutions or supplements without veterinary guidance.
Is gluconic acid bad for you?
No—it's considered safe at typical food-use levels (GRAS in the U.S.; no safety concern at reported uses per EFSA), though very high amounts could cause mild stomach upset due to acidity.
Is gluconic acid safe for dogs?
Generally yes at the low levels used in foods and pet products; large or undiluted amounts may irritate the GI tract, so consult your vet before intentional supplementation.
What is gluconic acid in food?
A mild organic acid from glucose used as an acidity regulator and chelating agent, helping control pH, stabilize minerals (as gluconates), and add gentle tartness.
