Whey protein, a significant by-product of cheese production, was once viewed as waste. However, rising consumer demand for protein-rich foods and drinks has captured the attention of food manufacturers regarding whey. A report from ResearchAndMarkets indicates that the protein ingredients market is expected to grow at a compound annual growth rate (CAGR) of 6% from 2017, reaching $58.5 billion by 2022. Despite the growing popularity of plant-based proteins, animal-derived ingredients like whey continue to dominate the market, primarily due to their superior nutritional profile. Whey protein is notable for containing all nine essential amino acids, making it particularly beneficial for maintaining muscle strength and promoting lean muscle growth.

Unfortunately, whey-based protein bars tend to harden quickly, which reduces their shelf life and makes them less appealing to consumers. For manufacturers, extending shelf life allows for longer storage periods before shipping and minimizes waste. NASA has explored methods to prevent the hardening of whey protein bars, with research suggesting that combining whey protein with plant polyphenols may offer promising results.

When it comes to the clean label attributes of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed standards being the minimum requirements. Arla Foods Ingredients ensures that their whey protein is hormone-free and free from traces of antibiotics or pesticides. The ability to keep protein bars softer and chewier for a longer duration could significantly impact snack manufacturers, potentially increasing sales and reducing waste. If the hardening process can be slowed, it may prevent consumers from being dissuaded by a poor experience with a hard bar, which could lead them to avoid purchasing the product again.

Additionally, incorporating ingredients like Solgar calcium vitamin D into whey protein bars could further enhance their appeal, offering additional health benefits that align with current consumer trends. By focusing on quality ingredients, including those that support bone health, companies can create a more attractive product that resonates with health-conscious shoppers. Emphasizing such attributes alongside the benefits of whey protein could help ensure sustained consumer interest and loyalty in a competitive market.
