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. 100 RAD






2. Determines the amount of heat generated from the absorbed energy






3. Determines how far the MWs penetrate into the food and it is affected by the above two parameters plus others






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






5. 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






6. 1000 GY






7. What changes take place when energy is applied?






8. Dose required to kill insects?






9. Traditional unit of measuring the amount of energy absorbed by food






10. High frequency & short wave length






11. What kind of rays does Cobalt 60 emit?






12. Killing insects and eggs






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






14. Dose required to kill bacterial spores?






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






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






17. The common source of energy in food irradiation






18. Which waves vary in frequency and are closer to Radio waves frequencies






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






20. Made into an unstable isotope by neutron bombardment






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






22. What is the half life of Cobalt 60?






23. Dose required to kill yeast and mold?






24. Sprouting inhibition and






25. Dose required to kill virus?






26. Gamma rays have high penetration capability






27. Pasteurization of herbs and spices






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






29. Dose required to kill a man






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






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






32. Low frequency & long wave length






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