How to Create a Clear High-Protein Drink

Soda sales have seen a steady decline over the last decade and, despite efforts to recapture market share with new flavor profiles, sales of soft drinks remains, well... soft. 

Consumers have been loud and clear: they want healthier drink options. Accordingly, ready-to-drink (RTD) sports and nutritional beverages have seen a large boost in popularity, with sales of RTD sports drinks in the U.S. coming in at $6.3 billion a year through retailers alone. 

This is great news for beverage manufacturers, but with a growing marketplace comes more competition. What makes today’s nutritional drinks stand out?

Protein As a Differentiator

According to Innova Market Insights, nearly 45% of U.S. sports nutrition launches in 2018 claimed “high” protein or “added” protein on their labels, with RTD protein beverages and sports drinks topping the category.

Why the surge? Many lifestyles, nutritionists and diet trends, such as the low-carb and Keto movement, now encourage larger protein intakes. Both athletes and non-athletes alike are choosing nutrition beverages and RTD sports drinks as a healthier alternative to sodas and other high-calorie, high-sugar beverages, and they’re not just drinking them before and after exercise, but throughout the day.

Why WPI is the Protein of Choice

The types of proteins used in RTD beverage formulations makes a major difference, not just as it relates to consumer preference but for beverage manufacturers as well.

Consumers want to ensure they receive the maximum health benefits from the protein-rich products they purchase. While there’s a lot of hype and marketing claims surrounding plant proteins in recent years, one traditional nutritional staple continues to lead the pack: whey protein isolate (WPI).

Educated consumers understand that whey protein provides the highest levels of protein and offers certain nutritional benefits not available in many plant-based alternatives. Most notably, branched chain amino acids found in whey protein are vital nutrients that increase muscle growth, decrease muscle soreness and fatigue and have been shown to reduce symptoms of liver disease. 

These nutritional benefits of high quality protein are in addition to others more commonly attributed to whey protein, including weight loss, reduced risk of diabetes and stroke, and anti-aging properties.

Due to increasing demand, the protein beverage market is understandably becoming saturated, leaving some consumers scratching their heads over which products to choose. Beverage manufacturers can feature the superior health benefits of WPI on their labels to help sway customers’ decisions. Some manufacturers, however, are scratching their heads as well as they try to overcome the various formulation challenges that come with clear protein drinks and other nutritional beverages.

Tips for Formulating High Protein Drinks 

In order to stand out in the sports drink market today, your beverage has to taste good, look good and offer nutritional value. While many beverage manufacturers are turning to WPIs to help fortify their formulations, they’re often faced with a number of formulation challenges, including:

  • Cloudiness — customers perceive a turbid appearance as a defect or indication of impurities
  • Unpleasant taste —consumers demand great flavor and increasingly desire unique flavor profiles
  • Separation — it’s difficult to achieve high protein levels without it separating from the rest of the liquid and forming an unpleasant sediment layer 

Because maintaining the appropriate clarity and clean flavor in sports and nutritional beverages is paramount, manufacturers need a solution beyond the quick fix of simply using opaque bottles for packaging and including “shake before opening” in fine print on the label. Unfortunately, many commodity WPIs necessitate such measures. This is especially true in trending acidic beverages, such as ciders, teas and iced coffees where lower pH levels are prominent. 

Consider Grande Ultra® as a solution. Unlike commodity proteins, Grande Ultra remains stable at pH levels as low as 3.5 due to our proprietary process, and its clean, neutral flavor ensures that your signature flavor profiles will shine through.
