Potassium gluconate is the potassium salt of gluconic acid, which is a naturally occurring compound that is found in fruit, honey, tea and wine. It can also be produced by the fermentation of glucose with certain moulds, to produce a colourless or white to tan crystalline powder that is very soluble in water. It is used as an anti-oxidant, sequestrant, stabiliser, and mineral supplement in food.http://www.creative-enzymes.com/product/Potassium-Gluconate_548.html
