Daftar Isi:
- Osteoporosis can be prevented by consuming calcium lactate. Calcium that is consumed is generally a micro-size. Micro-sized calcium is only absorbed by the body by about 50% which can cause deficiency. Eggshells are poultry waste that is rich in calcium and cheaply can be used as a source of dietary calcium through nanotechnology. Nanotechnology has been developed to increase calcium absorption in nano size. This study aimed to synthesize lactate nano-calcium from chicken eggshells by precipitation method as a food additive. Synthesis was carried out by reacting a solution of 1 mol/L calcium oxide eggshell as much as 20 ml mixed with a solution of 6 mol/L lactic acids as much as 30 ml with a ratio of 1:1.5 (v/v) for 30 minutes at 50°C at a speed of 500 rpm/minute using a magnetic stirrer. Ethanol 50% was added as much as 20 ml (v/v), in an oven at 105°C for 72 hours then mashed to obtain nano calcium lactate (NCaL) powder. The synthesized NCaL powder was characterized using Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), and Fourier Transform Infrared (FTIR). The results showed that chicken eggshells could be synthesized by the precipitation method into NCaL in the form of white crystals. Characterization with XRD showed that the diffraction angle was 2θ with the peaks of NCaL, namely 9.3800°, 10.3869°, and 22.9570°. Characterization with FTIR obtained a peak in the wavenumber from NCaL, namely 1,589.34 cm-1. Characterization using TEM showed that the crystal size of NCaL was 75 nm.
