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
b.) Modified atmosphere
c.) Vacuum
d.) Edible Films
e.) None of the above
Edible Films - This form of packaging is made of a polysaccharide, a protein, solid lipids, waxes,
and food-grade resin.
a.) Aseptic
b.) Modified atmosphere
c.) Vacuum
d.) Edible Films
e.) None of the above
e.) Nanoencapsulation of ingredients makes them sensitive to oxidation, pH, and other harsh
environmental factors - Which one does not belong?
a.) Casein polypeptides occur naturally as colloidal dispersions in milk
b.) Casein polypeptides occur as spherical micelles
, c.) Casein micelles have diameters ranging from 50 to 500 nanometers
d.) Stability of casein micelles makes them suitable as nanoencapsulators
e.) Nanoencapsulation of ingredients makes them sensitive to oxidation, pH, and other harsh
environmental factors
Nanoencapsulation - Which technology would be MOST acceptable to deliver encapsulated long
chained PUFAs in infant formula?
a.) Microencapsulation
b.) Nanoencapsulation
c.) Macroencapsulation
Nanocomposite - By embedding nanocrystals into plastic, researchers have created a molecular
barrier that can help prevent the escape of gases from brewed and carbonated beverages. This is an
example of a _________________ .
a.) vacuum package
b.) amorphous crystal state barrier
c.) nanocomposite
d.) macrocomposite
e.)smart food
Is between 1 and 10kGy - A medium dose of irradiation (for food applications)
a.) Is called radicidation
b.) Is between 0 and 10kGy
c.) Is between 1 and 10kGy
d.) Is over 10kGy
e.) Is called radapperization
False
To make it true: it must be Co-60 and Cs-137. IT'S SWAPPED
