Starch based particulate encapsulation process |
摘要 |
A wide range of materials may be encapsulated in a starch matrix by combining the material with a high temperature-stabilized pressurized dispersion of starch in the presence of salt. The temperature-stabilized starch dispersion acts as a protective colloid; upon subsequent rapid reduction of the pressure, the mixture cools and the starch polymer chains collapse upon themselves, encapsulating the core material in particulate form.
