Whey protein, a significant by-product of cheese production, was once deemed a waste material. However, with the rising consumer demand for protein-rich foods and beverages, food manufacturers have increasingly turned their attention to 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. While plant-based proteins are gaining traction, animal-derived ingredients like whey remain dominant in the market, primarily due to their more comprehensive nutritional profiles. Whey protein includes all nine essential amino acids, making it especially beneficial for maintaining muscle strength and function, as well as supporting the development of lean muscle mass.
However, whey-based protein bars tend to harden relatively quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, an extended shelf life translates to longer storage periods before shipping and reduced waste. NASA has explored methods to prevent the hardening of whey protein bars, with research suggesting that combining whey protein with plant polyphenols may be effective.
When considering the clean label credentials of whey protein, most manufacturers emphasize the importance of sourcing, advocating for non-GMO and grass-fed options at a minimum. Arla Foods Ingredients offers whey protein that is hormone-free and free from antibiotic or pesticide residues. The ability to keep a bar softer and chewier for a longer duration could have significant implications for snack producers, potentially increasing sales and decreasing waste. If the hardening process can be delayed, fewer consumers may be put off by a less-than-ideal experience, which could prevent them from avoiding the product in the future.
Additionally, incorporating ingredients like calcium citrate into these protein bars might provide added nutritional benefits, which could be particularly relevant in discussions around nursing implications. The integration of calcium citrate not only enhances the nutritional profile but could also contribute to the overall appeal of the product. By emphasizing the importance of sourcing and the potential benefits of ingredients such as calcium citrate, manufacturers can better address the needs and preferences of health-conscious consumers.
