|
The possiblity of sepiae os as a calcium supplement in food was studied. Elementary contents of sepiae os were as follows: Ca 53.254%, O 26.781%, Na 14.905%, Cl 4.37%, Sr 0.507%, P 0.064%, S 0.068% and Si 0.051%, respectively. Most of calcium in sepiae os was present as a form of CaCO₃. Surface area of sepiae os was found as 386 ㎡/g, and scanning electron micrograph showed sepiae os has multilayer structure. Buffering capacity of sepiae os showed same pattern as that of CaCO₃. With above results, sepiae os can be used as a calcium supplement in food with good characteristics.
