Whey protein, a significant by-product of cheese production, was once regarded as a waste material. However, with the rising consumer demand for protein-rich foods and beverages in recent years, food manufacturers have increasingly turned their attention to whey. According to a report from ResearchAndMarkets, the protein ingredients market is expected to grow at a compound annual growth rate (CAGR) of 6% starting in 2017, reaching $58.5 billion by 2022. Despite the growing popularity of plant-based proteins, animal-derived ingredients like whey continue to dominate the market, primarily due to their superior nutritional profiles. Whey protein includes all nine essential amino acids, making it especially appealing for maintaining muscle strength and function, as well as promoting the development of lean muscle mass.
However, whey-based protein bars often harden quickly, reducing their shelf life and making them less appealing to consumers. For manufacturers, an extended shelf life means products can be stored longer before shipping, which helps minimize waste. NASA has also explored methods to prevent the hardening of whey protein bars, with research indicating that blending 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 bare minimum standards. Arla Foods Ingredients’ whey protein is also free from hormones and contains no traces of antibiotics or pesticides. The potential to keep a bar softer and chewier for an extended period could have significant ramifications for companies producing these snacks, potentially enhancing sales and reducing waste.
Moreover, if the hardening process can be delayed, fewer consumers may be discouraged after a bad experience with a hard bar, which could prevent them from purchasing the item again in the future. This is particularly relevant when considering the nutritional benefits of integrating supplements like Solaray Calcium Citrate Supreme, which can support overall health and wellness. By maintaining the quality of whey protein bars, manufacturers can better meet consumer expectations and enhance their product offerings in a competitive market.
