"Early tests provided some of the fibrous texture to the final product, but it tasted more like turkey," Hsieh said. "In order to produce a more realistic product, we had to tweak the process and add extra fiber to give the soy a stringy feeling that tears into irregular, coarse fibers similar to chicken."
To create the soy chicken, Hsieh starts with a soy protein extracted from soy flour. The soy then goes through an extrusion cooking process that uses water, heat and pressure while pushing the mixture through a cylinder with two augers.
