For decades, manufacturers have traded off the full functional benefits of dairy in favor of necessary food safety and shelf life, but the biotech startup Exosomm says it has found a way for manufacturers to have both without compromise. According to the company, milk exosomes can survive digestion and interact with biological systems in ways traditional ingredients cannot, allowing them to deliver bioactive signals linked to gut health, immune function and inflammation management. The company recovers the exosomes from whey leftover from cheesemaking which otherwise would have limited value – creating a valuable, sustainable business opportunity for dairy producers. Whether milk exosomes ultimately become a mainstream functional ingredient will depend on regulatory progress, commercial adoption and continued clinical validation. If the company can deliver on that promise at scale, manufacturers may no longer have to choose between food safety and functionality.
