The Diversified Benefits of Whey Protein provides an overview of the main benefits of using whey proteins as targeted delivery systems in encapsulation processes, considering prerequisite steps such as binding mechanisms. The authors discuss how, according to current scientific knowledge, whey protein can reduce blood pressure and the risk of hypertension due to the presence of individual bioactive peptides formed after hydrolysis. The effect of whey protein on appetite/satiety of healthy overweight and obese individuals is investigated through a questionnaire wherein subjects were asked to indicate their feelings on the taste, aroma and edibility of a test beverage.
