Questions and Answers

What are bioactive components in foods?

  • Common constituents found in foods with no additional physiological function
  • Specific constituents found in foods with beneficial physiological function beyond nutritional function (correct)
  • Harmful constituents found in foods in large quantities
  • Constituents found in foods that only provide nutritional functions
  • Which component in milk is currently the foremost source of bioactive components?

  • Milk proteins (correct)
  • Lactose
  • Vitamins
  • Minerals
  • What is the state of the majority of the bioactivity of milk proteins?

  • Highly active in the original protein
  • Dormant, incomplete, or absent in the original protein (correct)
  • Non-existent in the original protein
  • Fully active in the original protein
  • Why have other components in milk besides milk proteins not been intensively studied?
