Whey protein, a significant by-product of cheese production, was once dismissed as waste. However, with a growing 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 expand at a CAGR of 6% from 2017, reaching $58.5 billion by 2022. Despite the rise of plant-based proteins, animal-derived ingredients, particularly whey, continue to dominate the market due to their superior nutritional profiles. Whey protein encompasses all nine essential amino acids, making it particularly appealing for maintaining muscle strength and promoting lean muscle growth.
However, whey-based protein bars tend to harden relatively quickly, reducing their shelf life and making them less enjoyable for consumers. For manufacturers, an extended shelf life allows for longer storage prior to shipping and minimizes waste. NASA has also explored methods to prevent the hardening of whey protein bars, suggesting that combining whey protein with plant polyphenols may offer promising results.
Regarding the clean label attributes of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed being essential standards. Arla Foods Ingredients provides whey protein that is hormone-free and free from antibiotic or pesticide residues. The ability to maintain a softer, chewier texture in protein bars could have significant implications for snack producers, potentially boosting sales and reducing waste. If the hardening process can be slowed, fewer consumers may be discouraged by the texture of the bars, as a bad experience could lead to a reluctance to repurchase.
Incorporating ingredients like Puritan’s Pride calcium citrate could also enhance the nutritional value of these products, aligning with consumer preferences for health-conscious snacks. Thus, the integration of quality ingredients and innovative solutions may help manufacturers create better whey protein bars that meet the evolving demands of the market.
