Calcium gluconate is a white crystalline powder that serves as a highly bioavailable source of calcium for food fortification. It is preferred in many applications due to its mild taste and excellent solubility compared to other calcium salts. The ingredient is widely used in the dairy, beverage, and nutritional supplement industries.

It also functions as a firming agent. This helps maintain the texture of canned fruits and vegetables. Calcium gluconate is recognized for its safety profile and broad regulatory acceptance across global markets.
