FSTC Exam 3 Questions and Answers
100% Solved | Graded A+
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,
dark and white) to create a creamy emulsion with half the fat. This would be
an example of nanoencapsulation.
True - ✔✔True or False: The 2 B's with respect to nanoparticle exposure
are greater bioavailability and greater bioactivity.
Modified Atmosphere - ✔✔The removal of air from a packaged food to be
replaced by N2 and/or CO2 refers to which type of packaging?
a.) Aseptic
