Food Science B

Measuring the food energy content in joules/gram seems highly...strange? It would make much more sense to measure it in kJ, or even kcal. I know it says 'joules/gram' in the rules, but perhaps can an event supervisor ask for it in kJ/g or kcal/g?

If the rules say "penalized or disqualified", can that include being tiered? I figure it does, but I'm not very familiar with this event.

Hi, I'm going to be supervising this event. I did it last year, but the topics are drastically different (dairy vs grains). Anyone who has taken a test for this year (or other event supervisors for this event!), typically how many lab tests (iodine, Benedict's, etc) does a student have to do, and typically what kind of foodstuff does a student have to measure with their calorimeter? Is a piece of bread okay to use? Thanks in advance

My teammate did this event this year a couple weeks ago and they had them measure a marshmallow with there calorimeter even though the topic is grains

Yup haha. It's because lots of grains don't burn continuously easily. I had my kids do corn chips...burned better than bread.

Someone gave me an Olive to burn. Like what the heck?!?!?!?!?!?!?!??!??!?!?!?

Looking over the rules, Rule 3a says "Part 1: This part of the test will include both experimental tasks and multiple choice or other questions about the chemistry of food AND food grains (any seed)." This would seem to say that while the event focus may be on grains this year, that the entire world of food chemistry is not off limits and that anything within the rough definition of the chemistry of foods is fair game. If they had wanted it to be just about grains, I'd think they would have used different wording... any thoughts?

Hi All,

In September 2016 the FDA finalized new nutrition label rules, but they are not filly implemented until summer of 2018. Should questions regarding nutrition labeling refer to the old nutrition label or the new one? Thoughts?

Thank you in advance!
