The main content of this paper focused on the conditions for duck blood hydrolysate microencapsulation （using tiny hole-coagulating bath method）, the figure and structure of products and its sustained release properties.The results showed that： the best formulation for duck blood hydrolysate microcapsules was sodium alginate concentration 2% （w/v）, CaCl2 concentration was 2% （w/v）, the ratio of dropping phase and coagulating phase was 1：2,the encapsulation efficiency reached 9t.78%.The microcapsules were carmine global particle which th...
