    I've slowly been watching this course over a year. In that time I've quit my job in automotive design and joined the nuclear industry as a mechanical engineer. I've also applied and been accepted to the University of Texas masters' of nuclear engineering program for this Fall. Thanks Dr. Short for the inspiration and your amazing teaching skills. I hope our paths cross one day.

    ‪A good reference on what things smell or taste like is "Common Fragrence and Flavor Materials" by Bsauer, Garbe, and Surburg. Wilwy, 4td ed, 2001.

    This is one of those subjects that I encountered years ago with one of my mom's friends who is completely against this. There seems to be a lot of confounding information that stuff that gets irritated becomes radioactive or somehow permanently damaged.

    35:59 I GET TO BE SMART!: Fats in foods are long carbon chains to a triglyceride backbone and not aromatic like benzene. Flavors on the other hand are often aromatic hence where the original latin or greek comes from (always mix the two up, should have paid more attention in english) those can be smelt in ppb and would screw up taste.

    Does this mean that the optimal temperature for irradiating food is < 0°C?

      Nothing. The radiation is not absorbed by the food.

    • @nathanielthomas4437
      @nathanielthomas4437 5 หลายเดือนก่อน

      The food is irradiated, not you. If you were irradiated that heavily, it would kill you, naturally. However, if you pay attention at around 10:00, he goes over which types of radiation are safe for food irradiation and won't leave any radioactivity in the food. Gamma radiation generally does not create radioisotopes at below 5 MeV.

      You can read for yourself in the link below. Scroll down for effects on meat and fruits. In short it does reduce the vitamins you get out your food.
