2. What is the effect of over thawing?
a) Discoloration
b) Low yield
c) Flavor enhancement
d) High yield
View Answer

Answer: a

defrosting graph
a) Conversion zone
b) Transition zone
c) Defrosting zone
d) Constant zone
View Answer

Answer: a
Explanation: The Defrosting graph can be obtained by plotting thawing time against temperature. The first zone is called temperature rise zone. The second zone is called as conversion zone or the mushy region. The third zone is called as thawing zone.

9. What is the advantage of using refrigeration method for thawing?
a) Process time
b) Cost
c) Efficiency
d) Microbial growth
View Answer

Answer: c
Explanation: The advantage of using refrigeration method for thawing is higher efficiency compared to other thawing methods. The frozen food is kept in refrigeration section for more than 24 hours for thawing process. The temperature should be below 400F.
