Whey protein is a significant by-product of cheese production that was once deemed a waste material. However, with the growing consumer demand for protein-rich foods and beverages in recent years, food manufacturers have increasingly recognized the value of whey. A report from ResearchAndMarkets indicates that the protein ingredients market is expected to expand at a compound annual growth rate (CAGR) of 6% from 2017, reaching a total of $58.5 billion by 2022. Although plant-based proteins are gaining popularity, animal-derived ingredients like whey continue to dominate the market due to their superior nutritional profile. Whey protein includes all nine essential amino acids, making it especially appealing for preserving muscle strength and function, as well as promoting lean muscle mass growth.

Nevertheless, whey-based protein bars often become hard relatively quickly, which reduces their shelf life and makes them less enjoyable for consumers. For manufacturers, an extended shelf life means products can be stored longer before shipping, leading to less waste. Research by NASA has explored methods to prevent the hardening of whey protein bars, suggesting that combining whey protein with plant polyphenols may show promise.

When considering the clean label attributes of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed standards being the minimum requirements. For instance, Arla Foods Ingredients provides whey protein that is hormone-free and free from antibiotic and pesticide residues. The ability to maintain a softer and chewier texture in bars could significantly impact snack producers, potentially increasing sales and minimizing waste. If the hardening process can be slowed down, fewer consumers may be dissuaded from purchasing the bars after a disappointing experience with a hard product.

In addition, incorporating ingredients like signature care calcium citrate could enhance the nutritional profile of whey protein bars. This could not only improve the texture but also add to the health benefits offered by the product. Overall, the integration of signature care calcium citrate alongside whey protein can play a crucial role in ensuring that these bars remain appealing to consumers, thus boosting market performance.
