Physicochemical properties of soy proteins extracted from check soybean cultivar 5601T and four new Tennessee soybean lines TN03-349, TN04-5321, TN08-002, and TN08-015 were compared. The protein extracted from 5601T had the lowest content of total protein and the lowest denaturation temperature and enthalpy (P < 0.05). The lowest solubility was observed at pH 5.0 for 5601T, TN04-5321, and TN03-349, while it was at pH 6.0 for the other two, which agreed with zeta-potential data. TN04-5321 and TN08-002 extract powder had a higher content of to...
