Ingredients that are purported to improve health or prevent certain medical conditions continue to have great consumer appeal. From protein enhancement to mineral fortification to collagen peptides—the future focus is on ingredients that promote better overall health.
The number of mineral-fortified food and beverages globally increases every year, with a wide range of trending claims. Depending on the product, there can be formulation challenges to overcome.
In fortifying with minerals, the ingredient properties that matter include solubility, dissolution rate, granulation, taste and bioavailability, plus price and potency. Solubility is the amount of a substance that will dissolve in a given amount of another substance, generally water. Initial solubility is the maximum amount that could be dissolved. However, stable solubility, the amount that can be kept in solution after a given period (such as 48 hours) is more important in a fortified product.
