Whey protein, a significant by-product of cheese production, was previously viewed as waste. However, the rising consumer demand for protein-rich foods and beverages has sparked interest among 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 continue to dominate the market due to their superior nutritional profile. Whey protein contains all nine essential amino acids, making it particularly appealing for maintaining muscle strength and promoting lean muscle growth.
Nonetheless, whey-based protein bars often harden quickly, reducing their shelf life and making them less enjoyable for consumers. For manufacturers, extending shelf life allows for longer storage before shipping and minimizes waste. NASA has explored methods to prevent the hardening of whey protein bars, finding that combining whey protein with plant polyphenols shows promise.
When it comes to the clean label attributes of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed being the minimum standards. Arla Foods Ingredients offers whey protein that is hormone-free and free of antibiotic and pesticide residues. The ability to keep a bar softer and chewier for a longer period could significantly impact companies producing these snacks, enhancing sales and potentially reducing waste. If the hardening process can be slowed, fewer consumers may be put off by a poor experience with a hard bar, which could deter them from future purchases.
Incorporating ingredients like calcium citrate 500 mg with vitamin D into these products could further enhance their appeal, providing additional health benefits. By utilizing calcium citrate 500 mg with vitamin D, manufacturers could attract health-conscious consumers looking for more than just protein. The integration of such beneficial components alongside whey protein can create a more desirable product that retains its texture and nutritional value over time.
