Abstract
The effect of germination on phytase activity in wheat NEAU123, triticale5305 and rye2 was studied in the present study. Germination significantly increased phytase activity by 2.04 times for wheat NEAU123 (3 d), 1.82 times for triticale 5305 (1 d) and 2.45 times for rye2 (1 d), respectively. It was safe for phytase in fresh malts kilned for 2 h at $40^{\circ}C$. Phytase in cereal seeds had strong heat stability. There was no loss of phytase activity in cereal seeds heated at $70^{\circ}C$ for 1 h, a little loss (${\leq}$5.46%) at $80^{\circ}C$ or $90^{\circ}C$. Even heated at $100^{\circ}C$, the phytase activity in wheat NEAU123, triticale5305 and rye2 remained 89.47%, 86.44% and 104.64%, respectively.
