摘要: Calcium is one of the most important elements in human body. Insoluble calcium particles are often used calcium-fortified food products, such as milk, dairy beverages or protein powders. However, their suspension may be unstable leading to precipitation products. In this study, three different kinds insoluble particles, i.e. hydroxyapatite (HA), tricalcium phosphate (TCP) and carbonate (CaCO3) were coated with amphiphilic phospholipids using a solvent-exchange method. Suspension stability these was effectively improved phospholipid coating, especially for HA TCP, more on surface two than CaCO3. Phospholipid coating increased electrostatic repulsions between preventing from aggregating precipitating. addition, digestibility phospholipid-coated tested simulated gastric juice, dissolution time prolonged through coating.
