Q6 Which of the following is an advantage of size reduction?
a) Enhanced beat/mass transfer b) Intimate contact with certain food items
e) Hoth of the above d) None of the above
Q6. Statement 1: Dispersion of one immiscible liquid into another also involves size reduction.
Statement 2: Leaching requires size reduction.
a) True, False b) True, True c) False, False d) False, True
Q7. Which of the following is NOT true with respect to size reduction?
a) Size reduction is an energy inefficient process as the energy required for grinding is very high
b) Some of the energy liberated in the formation of new small surfaces is the grinding energy required by food material per unit surface area to form new surface areas
and the rest is generally just heat
