Application
1. Commercial Baking Industry since most grains contain less than 0.05% calcium, the fillers are economical sources of supplemental calcium in enriched flour, cereals, baking powder, yeast, bread conditioners and cake icing, the gypsum products can also be found in canned vegetables and artificially sweetened jellies and preserves.
