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, interest from food manufacturers in whey has surged. A report from ResearchAndMarkets indicates that the protein ingredients market is expected to grow at a 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 comprehensive nutritional profiles. Whey protein is notable for containing all nine essential amino acids, making it especially beneficial for maintaining muscle strength and promoting the growth of lean muscle mass.
However, whey-based protein bars often harden quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, an extended shelf life allows for longer storage before shipping and reduces 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 aspects of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed options as the minimum standard. Arla Foods Ingredients provides whey protein that is hormone-free and free from antibiotic and pesticide residues.
The potential to maintain a softer and chewier texture in protein bars could significantly impact snack companies, driving sales and reducing waste. If the hardening process can be slowed, fewer consumers may be deterred from purchasing bars that harden after purchase, as a negative experience could discourage repeat buys. Additionally, incorporating nutrients like bluebonnet calcium citrate magnesium and vitamin D3 into these products could further enhance their appeal, making them not only a source of protein but also a beneficial option for overall health. With these enhancements, whey protein bars could become even more attractive to health-conscious consumers seeking convenient, nutritious snacks.
