Whey protein, a significant by-product of cheese production, was historically viewed as waste. 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. Despite the growing popularity of plant-based proteins, animal-derived ingredients like whey continue to dominate the market due to their superior nutritional profile. Whey protein provides all nine essential amino acids, making it particularly beneficial for maintaining muscle strength and promoting lean muscle growth.
Nevertheless, whey-based protein bars tend to harden relatively quickly, which reduces their shelf life and makes them less appealing to consumers. For manufacturers, an extended shelf life means the ability to store products longer before shipping, thereby minimizing waste. NASA has explored methods to prevent the hardening of whey protein bars, with research indicating that combining whey protein with plant polyphenols may offer effective solutions.
When it comes to the clean label standards of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed being the minimum requirements. Arla Foods Ingredients offers whey protein that is hormone-free and devoid of antibiotic and pesticide residues. The ability to keep protein bars softer and chewier for a longer duration could significantly impact snack-producing companies, potentially increasing sales and reducing waste. If the hardening process can be slowed, consumers may be less likely to abandon these products after a negative experience with a hard bar—an unpleasant encounter could deter them from future purchases.
In addition to the benefits of whey protein, it is also important to consider nutrient timing, such as the best time to take calcium citrate, which can enhance overall health and well-being. Incorporating this knowledge can further complement the protein intake strategy. By maximizing the effectiveness of both whey protein and calcium citrate, consumers can improve their nutritional outcomes and support their fitness goals.
