Whey protein, a significant by-product of the cheese-making process, was once viewed as waste. However, with the growing consumer demand for protein-rich foods and beverages, food manufacturers have increasingly turned their attention to whey. A report from ResearchAndMarkets indicates that the protein ingredients market is expected to grow at a CAGR of 6% from 2017, reaching $58.5 billion by 2022. Despite the popularity of plant-based proteins, animal-derived ingredients like whey continue to dominate the market due to their superior nutritional profiles. Whey protein offers all nine essential amino acids, making it especially appealing for maintaining muscle strength and promoting lean muscle growth.
However, a common issue with whey-based protein bars is that they tend to harden quickly, reducing their shelf life and palatability for consumers. For manufacturers, an extended shelf life allows for longer storage before shipping and minimizes waste. NASA has explored methods to prevent whey protein bars from hardening, suggesting that combining whey protein with plant polyphenols may hold promise.
When it comes to the clean label credentials of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed standards being the minimum requirements. Arla Foods Ingredients produces whey protein that is also hormone-free, with no traces of antibiotics or pesticides. The potential to maintain a softer, chewier texture in protein bars could significantly impact snack producers, driving sales and reducing waste. If the hardening process can be slowed, fewer consumers may be put off by a hard bar—a negative experience could prevent them from purchasing the item again.
In addition to whey protein, consumers are increasingly interested in products that offer added benefits, such as lifetime liquid calcium magnesium citrate. Incorporating such ingredients into whey protein bars could further enhance their appeal, providing additional health benefits. By integrating lifetime liquid calcium magnesium citrate, companies can create a more attractive product for health-conscious consumers, potentially leading to higher sales. Thus, the combination of whey protein and other beneficial ingredients like lifetime liquid calcium magnesium citrate may pave the way for innovative snacks that meet the evolving demands of the market.
