This set of Food Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Principles of Food Storage Stability”.

1. Which of the following physical qualities of storage food can be tested?
a) Odor measurement
b) Mechanical texture-meter
c) Odor measurement & Mechanical texture-meter
d) Neither of the mentioned
View Answer

Answer: c
Explanation: Both of the mentioned physical qualities of storage food can be tested.

2. Statement 1: Certain meats like beef and pork have a tendency to break apart when handled.
Statement 2: It is possible to predict the stability of food products from time-temperature data.
a) True, False
b) True, True
c) False, False
d) False, True
View Answer

Answer: b
Explanation: Certain meats like beef and pork have a tendency to break apart when handled. It is possible to predict the stability of food products from time-temperature data.

3. Relations between time and temperature to determine the stability of food products is obtained by using which of the following data?
a) Measure of product quality
b) The number of days stored
c) The storage temperature
d) All of the mentioned
View Answer

Answer: d
Explanation: All of the mentioned shows the relations between time and temperature to determine the stability of food products.

4. Three samples were subjected to certain treatments. Which among the following is unfit for consumption?
a) Air cool, air hold
b) Nitrogen cold, nitrogen hold
c) Air cool, nitrogen hold
d) All the mentioned are fit for consumption
View Answer

Answer: a
Explanation: It is important to remove air from the storage container. Both the odor and flavor of the first container deteriorated.

5. Which among these two – vitamin retention test and sensory quality test, should be used as a basis for determining temperature or time of storage of food items which are intended as primary or important sources of thiamine or ascorbic acid?
a) Vitamin retention test
b) Sensory quality test
c) Either of the mentioned
d) Neither of the mentioned
View Answer

Answer: a
Explanation: Vitamin retention test should be used as a basis for determining temperature or time of storage of food items which are intended as primary or important sources of thiamine or ascorbic acid. This is because these vitamins decreased faster than did either their color or palatability.

6. Results and objectives of an investigation are given in one of the points. Which could the correct answer be?
a) Need for broadening coverage so as to take account of geographical and seasonal variations in products
b) To determine how frozen food products behave under conditions of time and temperature
c) To discover and devise improvements in raw material selection, handling, processing and packaging
d) All of the mentioned
View Answer

Answer: d
Explanation: All of the mentioned are important criteria to be addressed and are plausible points that might have been covered.

7. Statement 1: Seasonal and regional variations have little effect on the sensitivity of a product to damage due to temperature elevation or variation.
Statement 2: Faulty processing/ packaging has a major effect in increasing the sensitivity of a product to damage.
a) True, False
b) True, True
c) False, False
d) False, True
View Answer

Answer: b
Explanation: Seasonal and regional variations have little effect on the sensitivity of a product to damage due to temperature elevation or variation. Faulty processing/ packaging has a major effect in increasing the sensitivity of a product to damage.

8. Frozen products differ markedly in their susceptibility to damage. This sentence can be accounted for by the following- Orange juice deteriorates rapidly but peas lose their quality slowly.
a) True
b) False
View Answer

Answer: a
Explanation: Frozen products differ markedly in their susceptibility to damage. This sentence can be accounted for by the following- Orange juice deteriorates rapidly but peas lose their quality slowly, both of which are frozen products.

9. Damage once done to a frozen product with respect to temperature can be undone.
a) True
b) False
View Answer

Answer: b
Explanation: Damage once done to a frozen product with respect to temperature cannot be undone. A product damaged due to an increase in temperature cannot be restored by decreasing its temperature again.

10. With respect to frozen products, a sample held for 1 week at -3 deg C will be indistinguishable from a sample of the same product at -17 deg C for a year.
a) True
b) False
View Answer

Answer: a
Explanation: With respect to frozen products, a sample held for 1 week at -3 deg C will be indistinguishable from a sample of the same product at -17 deg C for a year. Every 5 degC that the temperature is increased, the speed of quality loss increases by 2-2.5 times.
