| Abstract: | This study was performed to investigate the characteristics of milk tablets supplemented with nanopowdered eggshell (NPES) or nanopowdered oyster shell (NPOS). The particle size of NPES, NPOS, NPES with zinc (Zn‐NPES) and NPOS with activated zinc (Zn‐NPOS) ranged from 20 to 300 nm. The hardness of the milk tablets containing these calcium supplements did not differ significantly from that of the control milk tablets (P > 0.05). Regarding the sensory properties, the appearance, flavour, taste, texture and cumulative sensory score of all the test tablets were similar to those of the control tablets. In conclusion, the quality of all the test milk tablets was similar to that of the control. |
