There was effect of bone flour substitution on calcium levels of biscuits. The more the substitution of catfish bone flour, the more the calcium contents of biscuits. The highest calcium level of biscuit was given by substitution 30% (10,15% calcium). The hardness of biscuit was affected by the substitution of catfish bone flour.
