Whey protein, a significant by-product of cheese production, was once viewed as a waste material. 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 grow at a compound annual growth rate (CAGR) of 6% from 2017, reaching $58.5 billion by 2022. Despite the rising popularity of plant-based proteins, animal-derived ingredients like whey continue to dominate the market due to their superior nutritional profile. Whey protein is particularly appealing as it contains all nine essential amino acids, which are vital for maintaining muscle strength and promoting lean muscle growth.
However, whey-based protein bars tend to harden quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, a longer shelf life means they can store products for extended periods before shipping, resulting in reduced waste. NASA has explored methods to prevent the hardening of whey protein bars, with research indicating that combining whey protein with plant polyphenols may be a promising solution.
When considering the clean label credentials of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed options being the minimum standard. Arla Foods Ingredients’ whey protein is also hormone-free and free from antibiotic and pesticide residues. The potential to keep a protein bar softer and chewier for a longer time could have significant implications for snack producers, potentially boosting sales and minimizing waste. If the hardening process can be slowed, it may lead to fewer consumers being deterred by a hard bar, as a negative experience could result in them avoiding future purchases.
In addition, when discussing nutritional supplements, products like Citracal Calcium Plus D3 280 ct can complement the benefits of whey protein by supporting overall health and bone strength. By integrating such supplements into their offerings, companies can enhance the appeal of their whey protein products, ultimately attracting a broader customer base. The combination of quality sourcing and innovative formulations may well reshape consumer perceptions of whey protein, especially in the context of maintaining product integrity over time.
