The stability of BTCI has been investigated as function of pH and temperature, following its inhibitory activity against trypsin. The isolated inhibitor of 9,084 Da is stable over pH 3 to 10 at 25 o C. BTCI showed high thermal stability ranging from 25 to 95 o C at pH 3.0 and 7.0. However, the protein lost about 20 percent of its inhibitory activity over 75 o C at pH 8.2. The results indicated that BTCI is extremely stable to heat and pH as typical of Bowman-Birk inhibitors.
