Whey protein is a significant by-product of the cheese-making process that was once deemed a waste. However, as consumer demand for protein-rich foods and drinks has surged 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 compound annual growth rate (CAGR) of 6% from 2017, potentially reaching $58.5 billion by 2022. Despite the increasing popularity of plant-based proteins, animal-derived ingredients like whey remain dominant in the market due to their more comprehensive nutritional profiles. Whey protein includes all nine essential amino acids, making it especially appealing for maintaining muscle strength and function while promoting the development of lean muscle mass.
Nonetheless, whey-based protein bars often harden relatively quickly, which shortens their shelf life and makes them less appealing to consumers. For manufacturers, an extended shelf life means longer storage periods before shipping and reduced waste. NASA has explored methods to prevent the hardening of whey protein bars, suggesting that combining whey protein with plant polyphenols may offer promising results. Regarding the clean label attributes of whey protein, most manufacturers emphasize that sourcing is crucial, with non-GMO and grass-fed being essential requirements. Arla Foods Ingredients’ whey protein is also free from hormones and has no traces of antibiotics or pesticides.
The ability to maintain a bar’s softness and chewiness for longer could have significant ramifications for snack producers, enhancing sales and potentially minimizing waste. If the hardening process can be delayed, it could prevent consumers from becoming disenchanted with the bars after a negative experience with a hard product, which might deter future purchases. Additionally, incorporating ingredients such as Citracal calcium supplement D3 280 could provide added health benefits, making these bars even more appealing to health-conscious consumers. The inclusion of this supplement could further enhance the nutritional value of whey protein bars, reinforcing their position in the competitive market.
