Whey protein, a significant by-product of cheese production, was once regarded as a waste material. However, with the growing consumer demand for protein-rich foods and beverages in recent years, food manufacturers have 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 increasing popularity of plant-based proteins, animal-derived ingredients like whey still dominate the market, primarily due to their more comprehensive nutritional profile. Whey protein contains all nine essential amino acids, making it especially appealing for those looking to maintain muscle strength and promote the growth of lean muscle mass.
Nonetheless, whey-based protein bars tend to harden relatively quickly, reducing their shelf life and making them less enjoyable for consumers. For manufacturers, extending shelf life can lead to longer storage times before shipping and less waste. NASA has explored methods to prevent the hardening of whey protein bars, and its research suggests that combining whey protein with plant polyphenols may offer promising results.
When it comes to the clean label attributes of whey protein, most manufacturers agree that sourcing is crucial, with non-GMO and grass-fed standards being the minimum requirements. Arla Foods Ingredients’ whey protein is also hormone-free and free of antibiotic or pesticide residues. The potential to keep a bar softer and chewier for a longer period could significantly impact snack producers, enhancing sales and reducing waste. If the hardening process can be slowed, fewer consumers might be discouraged by a tough bar, as a negative experience could prevent them from purchasing the product again.
Additionally, incorporating supplements such as calcium citrate, magnesium, zinc, and vitamin D3 tablets into a diet can further support muscle health, complementing the benefits of whey protein. The integration of these vitamins and minerals can enhance overall nutritional value, making whey protein bars even more appealing to health-conscious consumers. By ensuring these ingredients are maintained in an optimal state, manufacturers can improve the consumer experience while also promoting the nutritional benefits of their products.
