Zinc gluconate is the
salt of
gluconate and
zinc II. It is an
ionic compound consisting of two moles of gluconate for each mole of zinc.Zinc gluconate is a popular form for the delivery of zinc as a
dietary supplement.It is found naturally, and is industrially manufactured by the
fermentation of
glucose, typically by
Aspergillus niger, but also by other
fungi, e.g.
Penicillium, or by
bacteria, e.g.
Acetobacter,
Pseudomonas and Gluconobacter. In its pure form, it is a white to off-white powder. It can also be manufactured by electrolytic oxidation, although this is a more expensive process. The advantages are a lower microbiological profile, and a more complete reaction, yielding a product with a longer shelf life.
