Whey protein, a significant by-product of cheese production, was once regarded as waste. However, rising consumer demand for protein-rich foods and beverages has led to increased interest from food manufacturers in whey. A report by ResearchAndMarkets projects that the protein ingredients market will grow at a CAGR of 6% from 2017, reaching $58.5 billion by 2022. Even with the growing popularity of plant-based proteins, animal-derived ingredients like whey still dominate the market due to their superior nutritional profiles. Whey protein provides all nine essential amino acids, making it highly appealing for maintaining muscle strength and promoting the growth of lean muscle mass.
One challenge with whey-based protein bars is that they tend to harden quickly, which reduces their shelf life and makes them less appealing to consumers. For manufacturers, a longer shelf life is advantageous as it allows for extended storage before shipping and reduces waste. NASA has explored methods to prevent the hardening of whey protein bars, with research indicating that combining whey protein with plant polyphenols may yield promising results.
Additionally, for whey protein to meet clean label standards, sourcing is crucial, with non-GMO and grass-fed being the baseline requirements. Arla Foods Ingredients provides whey protein that is hormone-free and free from antibiotic or pesticide residues. The ability to keep a protein bar softer and chewier for an extended period could significantly impact manufacturers, potentially increasing sales and minimizing waste. If the hardening process can be slowed, it may prevent consumers from forming negative impressions after purchasing a hard bar, which could discourage future purchases.
Incorporating elemental calcium in calcium citrate malate into these formulations may also enhance the nutritional value, providing an additional health benefit that could attract health-conscious consumers. The integration of such ingredients could further improve the marketability of whey-based products, appealing to a wider audience looking for both taste and nutrition.
