What is the primary objective of crop harvesting?

  1. To remove crops from the field

  2. To separate crops from unwanted materials

  3. To store crops for future use

  4. To process crops into food products


Correct Option: A
Explanation:

Crop harvesting is the process of removing crops from the field after they have matured. This is done to prevent spoilage and to facilitate further processing.

Which of the following is a common method of crop processing?

  1. Drying

  2. Milling

  3. Fermentation

  4. All of the above


Correct Option: D
Explanation:

Crop processing involves various methods to transform crops into usable products. Drying removes moisture, milling breaks down crops into smaller particles, and fermentation converts sugars into acids or alcohol.

What is the purpose of crop storage?

  1. To maintain crop quality

  2. To prevent crop spoilage

  3. To regulate crop supply

  4. All of the above


Correct Option: D
Explanation:

Crop storage aims to maintain crop quality, prevent spoilage, and regulate supply by controlling environmental conditions and using appropriate storage techniques.

Which food engineering principle is applied in pasteurization?

  1. Heat transfer

  2. Mass transfer

  3. Fluid flow

  4. Chemical reaction engineering


Correct Option: A
Explanation:

Pasteurization involves heating a liquid food product to a specific temperature for a certain duration to kill harmful microorganisms. This process relies on the principle of heat transfer.

What is the role of enzymes in food processing?

  1. To enhance flavor and texture

  2. To accelerate chemical reactions

  3. To improve nutritional value

  4. All of the above


Correct Option: D
Explanation:

Enzymes play a crucial role in food processing by enhancing flavor and texture, accelerating chemical reactions, and improving nutritional value through various enzymatic reactions.

Which of the following is a common food preservation technique?

  1. Canning

  2. Freezing

  3. Pickling

  4. All of the above


Correct Option: D
Explanation:

Canning, freezing, and pickling are widely used food preservation techniques that involve processing and treating food products to extend their shelf life and maintain quality.

What is the primary function of a food extruder?

  1. To mix and blend ingredients

  2. To shape and form food products

  3. To cook and sterilize food products

  4. To separate and purify food components


Correct Option: B
Explanation:

A food extruder is a machine used in food processing to shape and form food products by forcing a mixture of ingredients through a die under high pressure.

Which of the following is a common type of food packaging material?

  1. Plastic

  2. Metal

  3. Glass

  4. All of the above


Correct Option: D
Explanation:

Plastic, metal, and glass are widely used food packaging materials due to their ability to protect food products from external factors, maintain quality, and extend shelf life.

What is the purpose of quality control in food processing?

  1. To ensure food safety

  2. To maintain product consistency

  3. To comply with regulatory standards

  4. All of the above


Correct Option: D
Explanation:

Quality control in food processing aims to ensure food safety, maintain product consistency, comply with regulatory standards, and meet consumer expectations.

Which food engineering principle is applied in the design of food processing equipment?

  1. Fluid flow

  2. Heat transfer

  3. Mass transfer

  4. All of the above


Correct Option: D
Explanation:

The design of food processing equipment involves the application of various food engineering principles, including fluid flow, heat transfer, and mass transfer, to ensure efficient and effective processing operations.

What is the primary objective of food sterilization?

  1. To eliminate microorganisms

  2. To prevent food spoilage

  3. To extend shelf life

  4. All of the above


Correct Option: D
Explanation:

Food sterilization aims to eliminate microorganisms, prevent food spoilage, and extend shelf life by applying various methods such as heat treatment, radiation, or chemical preservation.

Which of the following is a common type of food additive?

  1. Preservatives

  2. Antioxidants

  3. Coloring agents

  4. All of the above


Correct Option: D
Explanation:

Preservatives, antioxidants, and coloring agents are commonly used food additives that serve various purposes, such as extending shelf life, preventing spoilage, and enhancing the appearance of food products.

What is the role of microorganisms in food fermentation?

  1. To convert sugars into acids or alcohol

  2. To produce enzymes that enhance flavor and texture

  3. To contribute to the development of characteristic aromas and flavors

  4. All of the above


Correct Option: D
Explanation:

Microorganisms play a crucial role in food fermentation by converting sugars into acids or alcohol, producing enzymes that enhance flavor and texture, and contributing to the development of characteristic aromas and flavors.
