Characteristic of Nano-Calcium Bone from a Different Species of Catfish (Pangasius hypophthalmus, Clarias batrachus, Hemibagrus nemurus and Paraplotosus albilabris)

Abstract

Fishbone contains mineral components that can potentially be exploited to improve the nutrition of food products. This research was aimed to determine the quality characteristics of nano-calcium bone from a different species of catfish. This research used an experimental method by producing nano-calcium from other types of catfish (Pangasius hypophthalmus, Clarias batrachus, Hemibagrus nemurus, and Paraplotosus albilabris) using 1M NaOH. The production of nano-calcium from the bone of different species of catfish produce a white fishbone nano-calcium color, with the whiteness degree of 90.7% (P.hypophthalmus); 88.9% (C.batrachus), 89.1% (H.nemurus), and 88.4% (P.albilabris). The moisture content in catfish bone nano-calcium in P.hypophthalmus. C.batrachus. H.nemurus, and P.albilabris was relatively similar, Ranging from 5.71%-6.12%. Calcium content of catfish bone nano-calcium very high in P.hypophthalmus, C.batrachus, H.nemurus, and P.albilabris were 87.4%; 89.6%; 89.1%, and 86.1% respectively. While the phosphorus level in P.hypopthalmus fishbone was 11.2%. C.batrachus fishbone was 9.4%, H.nemurus fishbone was 9.8%, and P.albilabris fishbone was 12.7%. The particle size of nano-calcium in P. hypophthalmus fishbone was 248-672 nm, in H.nemurus fishbone 206-594 nm, and nano-calcium in C.batrachus fishbone was 135-573 nm.
