Dough consistency and donut texture were measured using a modified method using a Texture analyzer equipped with a 5 kg load cell. For dough consistency, the center of the molded dough sample (1 cm thick ×1 cm diameter) was compressed with a cylindrical probe (diameter 20 mm). The probe penetrated 40% of the dough thickness at a speed of 2.0 mm/s. The first peak force from the three measurements made on each dough sample was recorded as the dough consistency. For donut texture, the fried sample was measured after 30 min of cooling. Due to the difference in the crust layer between the wheat donut and soy donut, the donut was compressed from its original height. The donuts were cut into 4 equal pieces (20 × 20 × 25 mm) and were compressed at the center to 35% of their original height at a test speed of 1.0 mm/s. The texture parameters, such as hardness, cohesiveness, springiness, chewiness, and adhesiveness, were measured.
