Abstract

The aim of the study was to determine the physicochemical and characterization of calcium nano catfish bone meal. Experimental method. Stage: Preparation of bone meal- characterization of chemical content through proximate, calcium, and phosphorus tests- characterization of physical properties through particle, morphological and visual measurements. The experimental design was a completely randomized design. All chemical analyzes are reported as average. Anova and Duncan test (P&#8804-0.05). The results of the research: characterization test of the chemical content of catfish bone calcium nano flour containing water content of 7.45%, ash 63.29%, protein 4.50%, fat 2.95%, carbohydrates 21.81%. And the calcium content of non-calcined bone meal 32.16% and 33.15% calcined both meet the Quality I standard. The results of the physical properties characterization test that the particle size of the uncalcined bone meal based on the percent number obtained 204.1 nm with PI (degree of non-uniformity of particle distribution 0.403) indicates nanoparticles. And the calcined bone flour based on the intensity percentage of 675.4 nm (86.1%) and 100.7 nm (13.9%) with a PI of 0.680 indicated the nanoparticles and the distribution of the particles tended to be uniform. The morphological results of a calcined and non-calcined bone meal with 500 times magnification had calcite-type crystals. Visually, the non-calcined calcium nano flour is bone white while the calcined is whiter in color. The benefits of alternative research for natural nano calcium sources from catfish bone meal can be used in the manufacture of food products to meet the calcium needs in the body
