Whey protein is a significant by-product of cheese production that was once seen as waste. However, growing consumer demand for protein-rich foods and beverages has sparked renewed interest among food manufacturers in whey. A report from ResearchAndMarkets indicates that the market for protein ingredients is expected to grow at a CAGR of 6% from 2017, reaching $58.5 billion by 2022. Despite the rise of plant-based proteins, animal-derived ingredients like whey still dominate the market due to their superior nutritional profile. Whey protein offers all nine essential amino acids, making it especially beneficial for maintaining muscle strength and promoting lean muscle mass growth.
One challenge with whey-based protein bars is their tendency to harden over time, which shortens their shelf life as they become less appealing to consumers. For manufacturers, an extended shelf life allows for longer storage before shipping and reduces waste. NASA has explored methods to prevent whey protein bars from hardening, suggesting that combining whey protein with plant polyphenols may offer promising results.
Regarding the clean label appeal of whey protein, most manufacturers emphasize the importance of sourcing, with non-GMO and grass-fed standards being essential. Arla Foods Ingredients provides whey protein that is free from hormones and has no traces of antibiotics or pesticides. The ability to keep a protein bar softer and chewier for longer could significantly impact snack-producing companies, driving sales and minimizing waste. If the hardening process can be effectively slowed, consumers may be less likely to be deterred by a negative experience from purchasing a hard bar, which could influence their future buying decisions.
Incorporating ingredients like Citracal Calcium D Slow Release 1200 could enhance the nutritional value of these bars. By including this calcium supplement, manufacturers can attract health-conscious consumers looking for additional benefits. The use of Citracal could also help maintain the ideal texture of the bars, encouraging repeat purchases. Overall, the synergy between whey protein and Citracal Calcium D Slow Release 1200 may lead to improved product formulations that appeal to a broader audience.
