Abstract
Methods used by the Industry to estimate protein quality of soybean meal (SBM) include KOH solubility (KOHsol), protein dispersibility index (PDI), urease activity (UA), and trypsin inhibitor activity (TIA). In general, meals with KOHsol values between 78 and 85%, PDI values between 15% and 35%, and UA values between 0.00 and 0.10 mg/g are considered of acceptable quality. Similarly, TIA values of less than 2.5?4.0 mg/g are considered best. However, there is no agreement among the different Institutions and publications with respect to the more suitable values for these variables in commercial SBM. The reasons for the wide range of values for these variables are not well understood. It is known that protein solubility and TIA changes with the methodology used and explain in part the high variability existing among laboratories.
