Abstract

The study aimed to formulate a high protein base as a dysphagia food and investigate the possibility of textural modification by applying microwave treatments. The formulated mixture contained 41.7% pea protein (dry basis), which exhibited shear thinning behavior. The application of microwave processing at 300, 500, and 700 W for 60, 120, and 180 s showed that at a higher level of energy induction by microwave, the hardness of the sample gradually increased from a fluid gel to a soft solid and more rigid levels. Processing at 300 and 500 W in the tested range showed that textural properties (hardness, adhesiveness, cohesiveness, springiness, gumminess, and chewiness) of the sample could be modulated within the recommended criteria for dysphagia food, providing the possibility of individualization of food texture for dysphagia disorder. Two main causes of these textural changes could be water evaporation and protein denaturation, in which, regarding the ratio of water evaporation to the size of textural changes, protein denaturation was thought to have the main impact on the phenomena.
