Whey protein is a significant by-product of cheese production that was once viewed as waste. However, with the growing consumer demand for protein-rich foods and beverages, food manufacturers have increasingly turned their attention to whey. A report by ResearchAndMarkets indicates that the protein ingredients market is expected to experience a compound annual growth rate (CAGR) of 6% from 2017, ultimately reaching $58.5 billion by 2022. Despite the rise of plant-based proteins, animal-derived ingredients, particularly whey, continue to dominate the market due to their comprehensive nutritional profile. Whey protein provides all nine essential amino acids, making it especially appealing for maintaining muscle strength and promoting lean muscle growth.
Nevertheless, whey-based protein bars tend to harden relatively quickly, reducing their shelf life and making them less enjoyable for consumers. For manufacturers, an extended shelf life means longer storage periods before shipping and less product waste. NASA has explored methods to prevent the hardening of whey protein bars, and their research suggests that combining whey protein with plant polyphenols shows significant promise.
When discussing the clean label credentials of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed options as a baseline. Arla Foods Ingredients offers whey protein that is hormone-free and devoid of antibiotic or pesticide residues. The ability to maintain a softer, chewier texture in protein bars could have substantial implications for snack manufacturers, potentially boosting sales and reducing waste. If the hardening process can be slowed, fewer consumers may be deterred by purchasing a bar that has become hard; a negative experience could discourage future purchases.
Additionally, incorporating the benefits of calcium citrate into whey protein formulations could enhance the overall appeal, as calcium citrate is known for its superior absorption and benefits in supporting bone health. By highlighting the benefits of calcium citrate, companies can attract health-conscious consumers looking for added nutritional value. Ultimately, addressing the hardening issue while promoting the benefits of calcium citrate could lead to a more favorable consumer experience and increased product loyalty.
