Bioactive peptides, though essentially fragments of proteins, serve roles far beyond mere nutrition. Present in a range of sources—dairy, meat, plants, marine organisms—these molecules demonstrate diverse physiological activities. They can neutralize free radicals, regulate blood pressure, inhibit bacterial growth, and modulate immune responses.The extraction and production of bioactive peptides typically involve enzymatic hydrolysis or fermentation, with emerging processing technologies aiming to maximize both their activity and absorption in the human body. By incorporating these peptides into functional foods, beverages, or nutraceuticals, it’s possible to support cardiovascular health, fortify immune function, and aid in metabolic regulation.For food scientists and industry professionals, bioactive peptides open the door to developing innovative products that address the increasing consumer interest in functional and therapeutic foods. Their value lies not only in proven health benefits but also in the ability to create appealing products that meet contemporary nutritional demands.
