Questions and Answers

What does the study by Harikrishna et al. emphasize about cold plasma technology?

  • Its ability to reduce the nutritional value of food products
  • Its impact on microbial decontamination in various food products (correct)
  • Its role in enhancing the taste of food products
  • Its use in increasing the water content of food products
  • According to Prakash et al., what is one of the benefits of Cold Plasma Technology in food processing?

  • Using excessive amounts of water in the decontamination process
  • Reducing the shelf life of food products
  • Preserving the quality and safety of food without affecting its properties (correct)
  • Increasing the chemical residues in food products
  • Why has Cold Plasma Technology gained recognition in the food industry?

  • By leaving chemical residues on the surface of food products
