摘要：

Toothpowder comprising natural calcium carbonate with a flavor oil coating is derived by agitating a particulated calcium carbonate bed and by spraying a nebula of flavor oil into the bed. The spray rate is controlled to preclude formation of agglomerated particles of the coated natural calcium carbonate.
