Instant protein beverages--once relegated to a post-workout supplement for the most active consumers are now a staple meal replacement for nearly all consumers.
With broader appeal comes more interest in the ingredients used in the product and increased demands to meet specific labeling or nutritional requirements. Sometimes, these demands result in the addition of vitamin-mineral blends, fiber, or protein, which increases the level of particulates. Consumers, in turn, may describe this texture defect in a finished beverage as “grittiness.”
At the same time, formulators must balance these texture demands with the ever-changing interpretations of clean label.
