What is the primary purpose of food irradiation?

  1. To enhance the flavor of food

  2. To sterilize food

  3. To add nutrients to food

  4. To change the color of food


Correct Option: B
Explanation:

Food irradiation is a process that uses ionizing radiation to kill bacteria, viruses, and other microorganisms in food, thereby sterilizing it and extending its shelf life.

Which type of radiation is commonly used in food irradiation?

  1. Ultraviolet radiation

  2. Gamma radiation

  3. Microwave radiation

  4. Infrared radiation


Correct Option: B
Explanation:

Gamma radiation, typically obtained from radioactive isotopes such as cobalt-60, is the most commonly used type of radiation in food irradiation due to its high penetrating power and effectiveness in eliminating microorganisms.

What is the maximum permissible dose of radiation allowed for food irradiation in India?

  1. 10 kGy

  2. 20 kGy

  3. 30 kGy

  4. 40 kGy


Correct Option: A
Explanation:

In India, the maximum permissible dose of radiation allowed for food irradiation is 10 kGy (kiloGray), as specified by the Food Safety and Standards Authority of India (FSSAI).

Which food items are commonly irradiated in India?

  1. Fruits and vegetables

  2. Meat and poultry

  3. Spices and herbs

  4. All of the above


Correct Option: D
Explanation:

In India, a variety of food items, including fruits and vegetables, meat and poultry, spices and herbs, are commonly irradiated to ensure their safety and extend their shelf life.

What are the primary benefits of food irradiation?

  1. Elimination of harmful microorganisms

  2. Extension of shelf life

  3. Improvement of nutritional value

  4. All of the above


Correct Option: D
Explanation:

Food irradiation offers several benefits, including the elimination of harmful microorganisms, extension of shelf life by delaying spoilage, and in some cases, improvement of nutritional value by reducing the loss of certain nutrients during storage.

Are irradiated foods safe for consumption?

  1. Yes, they are safe

  2. No, they are not safe

  3. It depends on the food item and irradiation dose

  4. There is no consensus on their safety


Correct Option: A
Explanation:

Irradiated foods are safe for consumption when processed according to established safety standards. Extensive research and regulatory oversight have confirmed that irradiation does not introduce any harmful substances or alter the nutritional value of food in a significant way.

What is the primary regulatory body responsible for ensuring the safety of irradiated food in India?

  1. Food Safety and Standards Authority of India (FSSAI)

  2. Atomic Energy Regulatory Board (AERB)

  3. Ministry of Health and Family Welfare

  4. Department of Atomic Energy


Correct Option: A
Explanation:

The Food Safety and Standards Authority of India (FSSAI) is the primary regulatory body responsible for ensuring the safety of irradiated food in India. FSSAI sets regulations, monitors compliance, and conducts inspections to ensure that irradiated food meets safety standards.

What is the international standard that governs food irradiation practices?

  1. Codex Alimentarius

  2. ISO 22000

  3. HACCP

  4. GMP


Correct Option: A
Explanation:

The Codex Alimentarius is the international standard that governs food irradiation practices. It provides guidelines and recommendations for the safe and effective use of irradiation in food processing.

Which international organization is responsible for setting standards and guidelines for food irradiation?

  1. World Health Organization (WHO)

  2. Food and Agriculture Organization (FAO)

  3. International Atomic Energy Agency (IAEA)

  4. All of the above


Correct Option: D
Explanation:

The World Health Organization (WHO), Food and Agriculture Organization (FAO), and International Atomic Energy Agency (IAEA) work together to set standards and guidelines for food irradiation, ensuring its safe and effective use.

What is the primary advantage of food irradiation over other food preservation methods?

  1. It does not alter the taste or texture of food

  2. It is more effective in eliminating microorganisms

  3. It is more cost-effective

  4. It is more environmentally friendly


Correct Option: B
Explanation:

Food irradiation is particularly advantageous because it is more effective in eliminating microorganisms, including bacteria, viruses, and parasites, compared to other food preservation methods.

Which of the following is NOT a potential concern related to food irradiation?

  1. Formation of harmful compounds

  2. Loss of nutritional value

  3. Alteration of food taste and texture

  4. Increased shelf life of food


Correct Option: D
Explanation:

Increased shelf life of food is a benefit of food irradiation, not a potential concern.

What is the primary challenge associated with the adoption of food irradiation technology?

  1. Lack of consumer acceptance

  2. High cost of irradiation facilities

  3. Limited availability of irradiation facilities

  4. All of the above


Correct Option: D
Explanation:

The adoption of food irradiation technology faces challenges such as lack of consumer acceptance, high cost of irradiation facilities, and limited availability of irradiation facilities.
