| Abstract: | The means of hydroxyapatite nanoparticles (n-HAP) preparation in biopolymer modifiers solutions under ultrasonic activation have been investigated. The use of casein as a modificator was suggested. It was shown that a protein solution with a concentration of 0.2% provides whisker n-HAP with a diameter of 2 nm and a length of 10 nm. This size of n-HAP is correlated to colloidal calcium phosphate in milk casein micelles. Synthesized nanoparticles can be used for the intensification of technologies processes in the dairy industry and for the fortification of food with calcium in the natural form. |
