Effects of dry heating and pH on pasting, thermal, and textural properties of corn starch containing soy protein isolate (SPI) were prepared by drying corn starch dispersions containing 3% SPI at 40℃ (unheated sample) or additionally heating dried mixtures at 130℃ (heated sample). Pasting properties of starch samples and textural properties of starch gels were measured using Rapid Visco-Analyzer (RVA) and Texture Analyzer (TA), respectively.
