This set of Meat Processing Multiple Choice Questions & Answers (MCQs) focuses on “Meat Processing Techniques”.
1. What is the other name for thawing?
a) Frosting
b) Defrosting
c) Re-frosting
d) After-frosting
View Answer
Explanation: Thawing is also called as defrosting. The perishable foods are not to be thawed on the counter for more than two hours. The general practice is to thaw the food in refrigeration but this process takes more time than the other defrosting process.
2. What is the effect of over thawing?
a) Discoloration
b) Low yield
c) Flavor enhancement
d) High yield
View Answer
Explanation: Some of the effects of over thawing are discoloration and loss of flavor. Over thawing can also lead to microbial growth. These microbial growths can lead to the enzymatic changes in the frozen products.
3. What is the effect of under thawing?
a) Discoloration
b) Low yield
c) Flavor enhancement
d) High yield
View Answer
Explanation: Some of the effects of under thawing are lower yield and lower quality. Under thawing of meat is very dangerous for the consumption. The frozen meat are difficult to fillet. Poor filleting can lead to low yield.
4. What is thawing process?
a) Reversal of the freezing process
b) Phase change from liquid to solid
c) Removal of oxygen from the product
d) Addition of cryogens
View Answer
Explanation: The thawing process is the reversal of the freezing process. Thawing or defrosting is done beforehand where it can be used later for the boiling or cooking process. This is a slow and steady process where ice crystals are liquefied at room temperature.
5. Microwave defrosting is only recommended for foods that are to be cooked immediately after thawing.
a) True
b) False
View Answer
Explanation: The microwave oven method of thawing is useful for defrosting small food products. It is a quick process compared to other thawing methods. Microwave defrosting method is recommended only when the foods are cooked immediately after thawing process.
6. Can we cook the frozen food without thawing?
a) True
b) False
View Answer
Explanation: The frozen foods can be cooked directly without thawing. However the time taken for the frozen food is higher when compared to the thawed food. The frozen foods also use more than 50% of heat than the thawed food.
7. What is the advantage of using cold water for thawing?
a) Process time
b) Cost
c) Efficiency
d) Microbial growth
View Answer
Explanation: Cold water thawing method is a fastest method to the thaw the frozen foods. Small packets of meat and its products thaw within an hour. Whereas the large meat products take 2-3 hours for thawing process.
8. Identify the missing zone in the below defrosting graph?
a) Conversion zone
b) Transition zone
c) Defrosting zone
d) Constant zone
View Answer
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
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.
10. What is the disadvantage of using refrigeration method for thawing?
a) Process time
b) Cost
c) Efficiency
d) Microbial growth
View Answer
Explanation: The disadvantage of using refrigeration method for thawing is long process time compared to other thawing methods. The thawing process for the frozen food nearly takes 24 hours. The food to be thawed is to be kept separately to avoid cross contamination.
