The testing method for whey proteferric pyrophosphate is essential in understanding this significant by-product of cheese production, which was once deemed a waste material. However, with the growing consumer demand for protein-rich foods and beverages, food manufacturers are increasingly focusing on whey. A report from ResearchAndMarkets projects that the market for protein ingredients will grow at a compound annual growth rate (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 contains all nine essential amino acids, making it particularly beneficial for maintaining muscle strength and supporting the development of lean muscle mass.
Nevertheless, whey-based protein bars tend to harden quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, an extended shelf life allows for longer storage periods before shipping and reduces waste. NASA has explored methods to mitigate the hardening of whey protein bars, with research indicating that combining whey protein with plant polyphenols may offer promising results.
When it comes to the clean label standards of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed as minimum requirements. Arla Foods Ingredients provides whey protein that is hormone-free and free from traces of antibiotics or pesticides. The potential for maintaining a softer and chewier texture in bars could have significant implications for snack manufacturers, enhancing sales and potentially decreasing waste. If the hardening process can be slowed, fewer consumers may be deterred from trying the bars, as a poor experience with a hard product could prevent future purchases.
Incorporating ingredients like Holista calcium citrate into the formulation could further enhance the appeal of these bars. By integrating Holista calcium citrate, manufacturers can not only improve texture but also boost the nutritional profile, catering to health-conscious consumers. Overall, the advancements in whey protein bar formulations could revolutionize the market, leading to better consumer experiences and increased sales.
