Abstract
A method for encapsulation of microparticles (e.g., fungal conidia), involving (i) suspending microparticles in an aqueous solution containing at least one sugar to form an aqueous suspension wherein the concentration of said sugar is about 0.1 to 10% w/v, and (ii) spray drying said aqueous suspension with a spray dryer, wherein the inlet temperature of said spray dryer is about 40° C. to about 140° C. and the outlet temperature of said spray dryer is about 20° C. to about 80° C.
Claims9
A method for encapsulation of microparticles, comprising suspending microparticles in an aqueous solution containing at least one sugar to form an aqueous suspension wherein the concentration of said sugar is about 0.1% to about 10.0% w/v, and spray drying said aqueous suspension with a spray dryer, wherein the inlet temperature of said spray dryer is about 40° C. to about 140° C. and the outlet temperature of said spray dryer is about 20° C. to about 80° C.;
- wherein said microparticles are fungal conidia, fungal spores, fungal hyphal cells, or mixtures thereof;
- wherein the amount of said sugar loaded on said encapsulated microparticle is about 2 to about 10 mg per one gram of said encapsulated microparticles.
