True - ✔✔True or False: Microencapsulation is a process by which very
tiny droplets or particles of liquid or solid material are surrounded or coated
with a continuous film of polymeric material.
True - ✔✔True or False: Tiny droplets of apple, orange and cranberry juice
each less than 30 nm in diameter have been infused into chocolate (milk,
