Whey protein, a significant by-product of cheese production, was once regarded 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 still dominate the market due to their superior nutritional profile. Whey protein includes all nine essential amino acids, making it particularly appealing for maintaining muscle strength and promoting the growth of lean muscle mass.
However, whey-based protein bars often harden quickly, reducing their shelf life and making them less enjoyable for consumers. For manufacturers, an extended shelf life allows for longer storage before shipping and minimizes waste. NASA has explored methods to prevent the hardening of whey protein bars, 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 emphasize the importance of sourcing, with non-GMO and grass-fed options being the minimum standard. Arla Foods Ingredients, for instance, provides whey protein that is hormone-free and free from antibiotic or pesticide residues. The ability to keep protein bars softer and chewier for a longer duration could significantly benefit snack producers, enhancing sales and potentially decreasing waste. If the hardening process can be slowed down, it may prevent consumer dissatisfaction when they encounter a hard bar, which could deter future purchases.
Moreover, for individuals concerned about bone health, incorporating whey protein along with supplements like calcium citrate or calcium carbonate for osteoporosis may offer additional benefits. These calcium sources can complement the high-quality protein in whey, supporting overall health and wellness. In summary, the advancements in whey protein bar formulations could not only improve consumer experiences but also align with health-conscious trends, including the use of calcium citrate or calcium carbonate for osteoporosis, thereby appealing to a broader audience.
