The crystals were washed in acetone and used for the preparation of Iron and Zn Gluconates.
UV Spectrum (taken by UV Spectrometer Model Labomed UVD 3500) of the iron gluconate shows the lmax at 239nm (Figure-3), while that of zinc gluconate was 229nm.
Results of this study done on rats showed that naturally organically bound zinc in yeast form is more bioavailable; that is, it is found in a greater concentrations in the liver than chemical forms such as gluconates.
A recent study comparing the bioavailability of zinc gluconate and zinc enriched yeast (Lalmin Zn) was recently conducted on human volunteers in Japan.
Users can quickly sort by mineral elements such as calcium, iron, magnesium, zinc or by chemical salts such as citrates,
gluconates, lactates and phosphates.
Founded in 1935, Purac has grown into the world's largest and most experienced manufacturer of natural lactic acid and lactates, as well as the leading producer of gluconates. Purac is a subsidiary of CSM, a Dutch multinational company involved in the production and marketing of food ingredients and confectionery with a presence in more than 100 countries.
Due to their high solubility, neutral flavor and high bioavailability, the most attractive applications for mineral lactates and gluconates are beverages and dietary supplements.
In addition to its lactate products, Purac America now has available a range of
gluconate products, with highly bioavailable mineral
gluconates, such as potassium, calcium, zinc and magnesium, Purac offers a variety of fortification solutions for food products.
Mineral Product: Ascorbates, aspartates, chelates, citrates,
gluconates, glycinates, multimineral trits, succinates, custom triturations, powders, granulates
