Whey protein, a significant by-product of the cheese-making process, was historically viewed as waste. However, with the rising consumer demand for protein-rich foods and beverages, food manufacturers are increasingly focusing on whey. 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 remain dominant due to their more comprehensive nutritional profiles. Whey protein contains all nine essential amino acids, making it particularly appealing for maintaining muscle strength and function, as well as promoting the growth of lean muscle mass.
Nevertheless, whey-based protein bars tend to harden quickly, reducing their shelf life and making them less appealing to consumers. For manufacturers, an extended shelf life means the ability to store products longer before shipping and 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 promising results.
When it comes to the clean label attributes of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed standards being the bare minimum. Arla Foods Ingredients’ whey protein is additionally hormone-free and free from antibiotic or pesticide residues. The potential to keep a protein bar softer and chewier for a longer duration could significantly impact companies in the snack production sector, potentially increasing sales and decreasing waste. If the hardening process can be slowed, fewer consumers may be deterred from purchasing these bars after experiencing one that is hard; a negative experience may discourage future purchases.
Incorporating ingredients like ccm calcium tablets into the formulation could also enhance the appeal of whey protein bars, providing additional health benefits. As consumer preferences continue to evolve, the integration of such components may become increasingly important for manufacturers aiming to meet market demands while ensuring product quality.
