Whey protein is a significant by-product of cheese production that was once regarded as a waste material. 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 compound annual growth rate (CAGR) of 6% from 2017, potentially reaching $58.5 billion by 2022. While plant-based proteins are on the rise, 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 beneficial for preserving muscle strength and function, as well as promoting the development of lean muscle mass.
Nevertheless, whey-based protein bars tend to harden relatively quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, extending shelf life allows for longer storage periods before shipping, thereby minimizing waste. NASA has explored methods to prevent the hardening of whey protein bars, and research indicates that combining whey protein with plant polyphenols may offer promising results.
When it comes to the clean label attributes of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed being the baseline requirements. Arla Foods Ingredients’ whey protein is also hormone-free and contains no traces of antibiotics or pesticides. The potential to keep a bar softer and chewier for a longer duration could have significant implications for snack manufacturers, enhancing sales and potentially decreasing waste. If the hardening process can be slowed, consumers may be less likely to abandon the bars after a negative experience with a hard product, which could otherwise discourage future purchases.
Additionally, the inclusion of calcium petites in whey protein products could further enhance their appeal by providing added nutritional benefits. This could attract health-conscious consumers looking for functional snacks that support muscle health and overall wellness. By focusing on the quality and texture of whey protein bars, companies can capitalize on the increasing trend towards protein-rich foods while ensuring a positive consumer experience.
