Segregation between b-glucan and dairy proteins was hypothesized to explain faster proteolysis by concentration of enzymes and proteins in a separated phase. It has been suggested that b-glucan riched fractions from barley and mushroom used in the production of extruded ready-to-eat snacks. The results showed that the inclusion of these fractions could be utilized by the food industry to manipulate the glycemic response of extruded snack products (Brennan, Derbyshire, Tiwari, & Brennan, 2013).
