Food irradiation is used to

Correct option is C

Food irradiation is a food safety and preservation technique that uses ionizing radiation to eliminate harmful organisms and extend shelf life. Here’s a detailed explanation:

• Kills Insects (Option a):

  • Irradiation is effective in controlling insect infestation in stored grains, dried fruits, and spices.

  • It disrupts the life cycle of insects at all developmental stages—eggs, larvae, and adults—thus preventing spoilage and loss.

• Kills Micro-organisms (Option b):

  • Food irradiation destroys bacteria, viruses, and parasites that cause foodborne illnesses (e.g., Salmonella, E. coli, Listeria).

  • This helps in making food safer for consumption and reducing the risk of diseases.

• Combined Benefit (Option c):

  • Since food irradiation can do both—kill insects and eliminate micro-organisms—it is widely used in preserving meat, seafood, fruits, vegetables, and spices.

  • It reduces spoilage without significantly affecting the taste, texture, or nutritional quality of food when used at approved doses.

• Not Correct (Option d):

  • This option is incorrect because irradiation does have significant benefits as outlined above.

Hence, Option (c) is correct as it includes both killing insects and micro-organisms.
