What is the primary objective of food processing?

  1. To enhance the nutritional value of food

  2. To increase the shelf life of food

  3. To improve the taste and texture of food

  4. To reduce the cost of food production


Correct Option: B
Explanation:

Food processing aims to extend the shelf life of food products by preventing spoilage and maintaining their quality.

Which food preservation technique involves the removal of water from food?

  1. Freezing

  2. Dehydration

  3. Canning

  4. Fermentation


Correct Option: B
Explanation:

Dehydration, also known as drying, removes water from food to inhibit microbial growth and extend its shelf life.

What is the role of pasteurization in food processing?

  1. To enhance the flavor of food

  2. To sterilize food products

  3. To prevent enzymatic browning

  4. To destroy harmful microorganisms


Correct Option: D
Explanation:

Pasteurization is a heat treatment process that eliminates disease-causing microorganisms from food products, ensuring their safety for consumption.

Which food processing technique involves the addition of salt to preserve food?

  1. Pickling

  2. Smoking

  3. Freezing

  4. Irradiation


Correct Option: A
Explanation:

Pickling involves preserving food in a brine solution, which inhibits microbial growth and enhances flavor.

What is the primary function of food additives?

  1. To improve the nutritional value of food

  2. To enhance the taste and appearance of food

  3. To prevent food spoilage

  4. To reduce the cost of food production


Correct Option: B
Explanation:

Food additives are substances added to food to improve its flavor, color, texture, or other sensory properties.

What is the purpose of quality control in food processing?

  1. To ensure the safety of food products

  2. To maintain the consistency of food quality

  3. To reduce production costs

  4. To increase the shelf life of food products


Correct Option: A
Explanation:

Quality control in food processing aims to ensure that food products are safe for consumption, meet regulatory standards, and maintain consistent quality.

Which food processing technique involves the use of high pressure to preserve food?

  1. Canning

  2. Freezing

  3. High-pressure processing (HPP)

  4. Irradiation


Correct Option: C
Explanation:

High-pressure processing (HPP) applies high pressure to food products to inactivate microorganisms and extend their shelf life.

What is the role of enzymes in food processing?

  1. To enhance the flavor of food

  2. To improve the texture of food

  3. To accelerate chemical reactions in food

  4. To prevent food spoilage


Correct Option: C
Explanation:

Enzymes are used in food processing to catalyze specific chemical reactions, such as the breakdown of proteins, carbohydrates, and fats.

Which food processing technique involves the use of radiation to preserve food?

  1. Freezing

  2. Canning

  3. Irradiation

  4. Dehydration


Correct Option: C
Explanation:

Irradiation exposes food products to ionizing radiation to eliminate microorganisms and extend their shelf life.

What is the primary function of food packaging?

  1. To protect food from contamination

  2. To maintain the quality of food

  3. To enhance the appearance of food

  4. To reduce the cost of food production


Correct Option: A
Explanation:

Food packaging serves to protect food products from contamination, spoilage, and physical damage during transportation and storage.

Which food processing technique involves the fermentation of food by microorganisms?

  1. Canning

  2. Freezing

  3. Fermentation

  4. Irradiation


Correct Option: C
Explanation:

Fermentation involves the controlled growth of microorganisms, such as bacteria or yeast, to convert food components into desired products, such as yogurt, cheese, and beer.

What is the role of modified atmosphere packaging (MAP) in food preservation?

  1. To remove oxygen from food packaging

  2. To add carbon dioxide to food packaging

  3. To control the humidity inside food packaging

  4. All of the above


Correct Option: D
Explanation:

Modified atmosphere packaging (MAP) involves modifying the composition of gases inside food packaging to extend shelf life and maintain product quality.

Which food processing technique involves the application of heat to sterilize food products?

  1. Freezing

  2. Canning

  3. Dehydration

  4. Irradiation


Correct Option: B
Explanation:

Canning involves heating food products in sealed containers to sterilize them and prevent spoilage.

What is the primary function of food labeling?

  1. To provide information about the nutritional content of food

  2. To list the ingredients used in food products

  3. To display the manufacturer's contact information

  4. All of the above


Correct Option: D
Explanation:

Food labeling serves to provide consumers with essential information about the nutritional content, ingredients, and manufacturer details of food products.

Which food processing technique involves the application of low temperatures to preserve food?

  1. Freezing

  2. Canning

  3. Dehydration

  4. Irradiation


Correct Option: A
Explanation:

Freezing involves lowering the temperature of food products to inhibit microbial growth and extend their shelf life.
