Resumo
Thiamine was used for producing textured soy protein (TSP) with meat odor. The effects of the moisture of soy protein concentrate (SPC) and screw speed on the physical, technological, and sensory characteristics of the TSP were evaluated and the effects of thiamine were evaluated on the same characteristics as well. The SPC moisture-affected hue, protein solubility, emulsion stability, meat odor intensity, and ideal of the intensity of meat odor of TSP while the screw speed affected hue and emulsion stability. At the center point of the experimental design, the SPC moisture enhanced the intensity of the meat odor and the ideal of the intensity of the meat odor of TSP. The addition of thiamine enhanced all the sensory characteristics and did not impair the physical and technological properties of TSP. The use of thiamine before extrusion represents a new option as an ingredient for obtaining TSP with meat odor. Novelty impact statement: Thiamine has been used for producing textured soy protein (TSP) and it improved the sensory characteristics related to the meat odor. The addition of thiamine did not impair the physical and technological properties of TSP. Such results are relevant to academia and to the food industry, contributing to the area of plant-based foods.
