ABSTRACT:
This invention provides methods and compositions to preserve bioactive materials in a matrix of powder particles. Methods provide high-pressure gas spraying and/or near supercritical spraying of formulations followed by drying in a stream of conditioned gas to form stable powder particles containing bioactive materials.
