Abstract

Belida (Chitala sp.) bone is one of the waste from amplang processing which not treated properly
yet until now especially in East Kalimantan. One type of the usage of this waste is processed to fish bone
powder as calcium source. The aim of this study was to determine the best treatment (boiling frequency)
to produce belida fish bone powder which the best characteristics based on highest calcium content. The
processing applied alkali method (used NaOH) to produce belida fish bone powder. The treatment of this
study was boiling frequency, i.e. P1 (once boiling), P2 (twice boiling), P3 (three times boiling), and P4 (four
times boiling) with 30 minutes on each boiling. Observed parameters in this study were moisture content,
ash content, protein content, fat content, calcium content, phosphor content, pH and whiteness. The results
showed that four times boiling gave the best result with the highest calcium content 31.31%. The range of
calcium content was 28.25%-31.31%. While the range of phosphor content was 3.95%-4.06%.
