Calcium ascorbate is a compound with the molecular formula CaC12H14O12. It is the calcium salt of ascorbic acid, one of the mineral ascorbates. It is approximately 10% calcium by mass.

As a food additive, it has the E number E 302. It is approved for use as a food additive in the EU,[2] USA[3] and Australia and New Zealand.[4] Among its many uses is to keep apples fresh, so they do not turn brown quickly. This process arose out of a Cooperative Research and Development Agreement with the USDA and Mantrose Haeuser, a U.S specialty coatings manufacturer, who hold a joint patent covering the application of calcium ascorbate to maintain shelflife in fresh-cut fruit and vegetables.[5]
