It is well known that madidihang fishbone contains a high number of mineral especially Ca and P; however, this fishbone also has high contents of protein and fat. Three types of boiling solutions i.e. water, acetic acid and chloric acid were performed in order to reduce the protein and fat contents prior to be processed become powder. Mainly the physico-chemical characteristics of madidihang fishbone powder were not affected significantly by boiling solutions; however, boiling in acetic acid produced the highest percent solubility of Ca and P. Based on organoleptic test (scoring test), adding 0,8% and 1,6% of madidihang fishbone powder into cracers products namely formulas A2 and A4 respectively gave the high average values of color, flavor and taste; and they also had the higher values of appearance, taste, color and crispiners in comparison to commercial product. Cracers formulas A2 and A4 contained high number of Ca and P and significantly different with control and commercial product, they also had the highest percent solubility of Ca and P.
