Protein digestibility and techno-functional performance of milk-alternative prototypes based on combinations of lentil and cereal protein

Abstract

DIAAS (PIVDIAAS) of the emulsions. Techno-functional properties such as particle size, rheological behaviour and physical stability were investigated. The PIVDIAAS of the combined protein emulsions was found to be 0.72, 0.78, 0.83, 0.98 for lentil + wheat, lentil + oat, lentil + BSGP and lentil + rice emulsions, respectively, compared to 0.48, 0.25, 0.5, 0.67 and 0.81 determined for the emulsions based on lentil, wheat, oat, BSGP and rice alone, respectively. The emulsions based on the combination of lentil and cereal protein also showed improved physical stability regarding sedimentation and creaming, and a higher whiteness index of the emulsions. It could be shown that the combination of lentil and cereal protein is a promising strategy to achieve PBMAs with improved protein quality and
