Whey protein, a significant by-product of cheese production, was once viewed as waste. However, the growing consumer demand for protein-rich foods and beverages has piqued the interest of food manufacturers in 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 increasing popularity of plant-based proteins, animal-derived ingredients like whey still dominate the market due to their superior nutritional profile. Whey protein provides all nine essential amino acids, making it particularly beneficial for maintaining muscle strength and promoting lean muscle mass growth.
However, whey-based protein bars tend to harden relatively quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, a longer shelf life means they can store products for extended periods before shipping, thus minimizing waste. NASA has explored methods to prevent the hardening of whey protein bars, suggesting that combining whey protein with plant polyphenols could be a promising solution.
Regarding the clean label aspects of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed being the bare minimum. Arla Foods Ingredients ensures that its whey protein is hormone-free and free from antibiotic and pesticide residues. The ability to keep a protein bar softer and chewier for a longer time could significantly impact companies producing these snacks, potentially increasing sales and reducing waste. If the hardening process can be delayed, it may result in fewer consumers being put off by the texture of the bars, as a negative experience might prevent them from repurchasing in the future.
In this context, it’s interesting to consider the health implications of other supplements, such as Kirkland calcium citrate magnesium and zinc. While these supplements offer various health benefits, it’s essential to be aware of their side effects. Therefore, as the market evolves, both whey protein and these other nutritional products must be carefully formulated to maintain quality and consumer satisfaction.
