This set of Fruits Processing Multiple Choice Questions & Answers (MCQs) focuses on “Fresh Fruit Storage”.
1. What is the best temperature to store fresh fruit?
a) 0 to 10°F
b) 3 to 5°F
c) 20 to 30°F
d) 32 to 55°F
View Answer
Explanation: In fruits, the cellular breakdown and senescence cannot be stopped. But it can be slowed with ideal storage conditions. The fresh fruits and vegetables require low temperatures ranging from 32 to 55°F. It also needs high relative humidity with 80 to 95% to lower respiration of the fruits. These conditions slow down the transpiration rates and metabolic rate.
2. What is the safest food storage container?
a) Glass
b) Steel
c) Iron
d) Plastic
View Answer
Explanation: Generally the reusable non-plastic food containers are used for storing the fruits. Glass, stainless steel, silicone, or ceramic are some of the reusable containers. All four are safe and non-toxic. These materials are more expensive than plastic.
3. What is the safest container to freeze fruits in?
a) Steel containers and card boxes
b) Flexible pouches and card boxes
c) Steel and flexible pouches
d) Rigid containers and flexible bags
View Answer
Explanation: Flexible bags and rigid containers are safe for freezing the fruits. Rigid containers are made of plastic and glasses. These are suitable for liquid and semi liquids. Rigid containers consist of straight lines at the end which helps in removing frozen products from refrigeration.
4. Does vacuum sealing prevent freezer burn?
a) True
b) False
View Answer
Explanation: Vacuum sealing prevents the food from freezer burn or from dehydration. When the water gets inside the product, it can cause freeze burn. Therefore the vacuum bag confines the food from water and air contact. The moisture cannot evaporate from the food and acts as an excellent barrier.
5. What are the requirements needed for the storage units?
a) Ventilation
b) Relative humidity controller
c) Temperature controller
d) Ventilation, relative humidity controller and temperature controller
View Answer
Explanation: Some of the requirements needed for the storage units are well ventilation, relative humidity controller, temperature controller and there should be no AC Duct inside the store room. The unit should be under strict sanitation methods. Items used frequently should be placed near the exit door.
6. What is perpetual stock taking?
a) Goods received or issued is recorded immediately
b) Goods received or issued is recorded weekly
c) Goods received or issued is recorded monthly
d) Goods received or issued is immediately recorded quarterly
View Answer
Explanation: In perpetual stock taking system, goods received or issued is immediately recorded on stock taking sheet. It is compiled at the end of the day. In this system, at any given time people know the value of stock in hand.
7. What is the temperature at which the apples are stored?
a) 10°F
b) 3 °F
c) 20 °F
d) 32 °F
View Answer
Explanation: The ability of apples to be stored for long periods largely depends upon variety, maturity and soundness at harvest along with storage temperature. The apples are to be in good color and mature, but firm. They should be free of insect damage and mechanical injuries.
8. What percentage should be the relative humidity in storage conditions for fruits?
a) 80 to 85
b) 70 to 75
c) 60 to 65
d) 90 to 95
View Answer
Explanation: Most of the fruits can be stored at 90 to 95% relative humidity. If the humidity is less, then the produce gets dehydrated. The storage unit should be well ventilated. The unit should also restrict the entry of the rodents and other insects.
9. Which one of the following is the oldest method of storing fruits?
a) Drying
b) Canning
c) Modified control storage
d) Irradiation
View Answer
Explanation: Drying is one of the ancient ways to preserve the foods. The basic process includes removal of moisture from the produce. This can be achieved by a dehydrator, oven and sun drying. The sun drying is labor intensive and also requires more time for uniform dried product.
10. Higher food quality can be maintained with canning rather than drying.
a) True
b) False
View Answer
Explanation: Canning can maintain the food quality rather than drying. Canning disengages the enzyme activity in the produce which affects texture, flavor and color. Canning includes added costs like purchase of equipment, containers and supplies.
11. What happens if the relative humidity is not maintained in the storage unit?
a) Increases the water loss
b) Improves the color
c) Improves the flavor
d) Extends the shelf life
View Answer
Explanation: Maintaining high humidity around harvested produce reduces water loss. If is not maintained then, it result in decreased returns through poor quality and loss of saleable weight. High humidity should be used with low temperature storage because humidity and warmth combined favors the growth of fungi and bacteria.
12. How to maintain the storage and stability of fruits?
a) Relative humidity
b) Pressure
c) Water activity
d) Moisture content
View Answer
Explanation: Regulating the humidity is one of the ideal ways to maintain the storage of fruits. The fruit release moisture and shrink over time. Therefore it is important to maintain moisture levels during storage which can be done by controlling the humidity.
13. What are the methods of storing?
a) Drying
b) Freezing
c) Curing
d) Drying, freezing, curing
View Answer
Explanation: There are various methods to store the fruits. Some of the processes are drying, salting, pickling, freezing and curing. These methods ensures that the product have good quality and extended shelf life. It also improves the color, flavor and overall acceptability of the product.
14. What are classifications in food storage?
a) Dry storage and refrigerated storage
b) Dry storage and frozen storage
c) Dry storage, refrigerated storage and frozen storage
d) Refrigerated storage and frozen storage
View Answer
Explanation: There are three types of food storage options. Dry storage refers to the storing of items which does not require a climate controlled environment. The refrigerated storage is defined as foods that require storage at a cool temperature, but not a freezing temperature. The frozen food storage refers to the storage where foods that are required to store under freezing temperature.
