Instructions:
  • Answer 33 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Determines how far the MWs penetrate into the food and it is affected by the above two parameters plus others






2. 1000 GY






3. The food category - the purpose of irradiation - and the dose permitted in KGY

11. Pasteurization of herbs and spices






12. Sprouting inhibition and






13. Is also used in limited extent in food irradiation.






14. Dose required to kill insects?






15. Indirect Effect- ionization of molecules that produces ion pairs (by knocking off an electron) and free radicals (by breaking bonds) result in chemical reactions that interrupt biological functions






16. Utilizing (IR) to achieve biological stability of food by inhibiting or minimizing spoilage reactions






17. What kind of rays does Cobalt 60 emit?






18. The common source of energy in food irradiation






19. Direct Effect- a bullet-like effect with high energy particles impacting the vital parts of the cell






20. -the more complex the biological system is the less amount of IR required to induce changes

26. Food treated with ionizing radiation (IR) is said to be






27. Made into an unstable isotope by neutron bombardment






28. These rays have no penetration depth hence it will only achieve surface inactivation of microorganisms






29. What changes take place when energy is applied?






30. Describes a continuous range of radiation energy having an electric and a magnetic component






31. Dose required to kill virus?






32. The quantity of radiation that results in the absorption of 100 ergs per gram of food






33. Determines the affinity of a food system to absorb microwaves
