Consumers are increasingly seeking functional beverages that support holistic health benefits rather than simply emphasizing protein content. There is growing interest in formats that deliver protein in ways that align with the body’s needs and can be consumed throughout the day. Consumers are seeking new-to-market functional beverages that not only deliver meaningful nutrition but also maintain great taste and visual appeal. 

Achieving clear appearance in protein-containing beverages is a technical challenge, especially for more than 5% protein content and in ready-to-drink, low-acid (neutral pH) beverage systems. Typically, whey proteins are used for clear beverage applications. However, at neutral pH levels (low acid), there is generally an increase in turbidity and undesirable sulfuric notes in flavor and aroma after the required thermal treatment.
