Abstract: The enzymatic hydrolysis of pig bone powder was optimized with respect to enzyme type, temperature, time, substrate concentration and pH by one-factor-at-a-time method in combination with orthogonal array method. The best hydrolysis results were achieved by using papain to hydrolyze pig bone powder for 4 h at pH 8, 55 ℃ and an enzyme dosage of 10000 U/g.

Key words: pig bone powder, enzymatic hydrolysis conditions, TCA-NSI (trichloroacetic acid-nitrogen solution index), bitterness
