reported a decrease in TIU from 38 to 0 TIU/mg
when SSBM was autoclaved for 121°C for 120 min. In
a more recent study, Batal et al. (2000) reported a reduction
in TIU from 44.2 to 2.6 TIU/mg when soybean
flakes were autoclaved at 121°C for 36 min. The urease
activity test has been used to evaluate processing time
and technique, but has not been found to be important
for poultry production (McNaughton et al., 1981).
