Answers to Some Selected Questions

Your Questions My Responses
If there's one thing you want your students to take away from the course, what would that be? Processing is necessary in the way we live; I hope you will gain the skills to justify why you choose one processed food over others
Will there be sampling? Absolutely!
What advices can you give to me so I can deal better with your course and also with the Canadian system of Univertisy education in general? Let's chat!
  • How many hours do you recommend studying?
  • Will there be videos to enhance material understanding?
  • Staying focus while studying is the key; there are so many interesting video on youtube on foods that one (myself included) can be easily distracted.
  • Yes, a few, not a whole lot.
Project Guideline? Will be ready by January 20.
  • Will there be math? I hate math.
  • Do I need chemistry background?
  • Will this class be really difficult for someone with a minimal background in science?
  • This is a science course and there will be some math. About 5 to 15% of the second midterm and the final exam will be on calculation. I don't think it is a BIG deal unless you really, really need to get a 98% to get into your dream program or obtain a major scholarship :) Let me know otherwise. I am also happy to offer additional help.
  • Again, this is a science course so some chemistry is needed. I try to tone it down to a 'foodie magazine' level.
  • I won't say 'really difficult'. FNH 200 is indeed a very popular 'science elective' for Arts students. I have worked with many students who hadn't had any science since Grade 10 (over 5 years) by the time they took FNH 200. Again, you have my support and your fellow classmates :)
Why are we allowed only one cheat sheet for the exam?

I consider the use of 'cheat sheet' is indeed a way to test your note-taking skills.

  • Do you know what are the most challenging information for you and should be included on the cheat sheet?
  • Can you organize the info on the cheat sheet so that you can find the info right away during the midterm under pressure?
  • Do you understand how information learned in one lesson is related to those in other lessons?

By the way:

  • There is no limit on font size.
  • Magnifying glass is allowed.
How to study for a science course? I'm used to text and paper-writing. There will be a lot of information and facts. You need to find ways to weave, connect individual pieces of information to form a network of knowledge that makes sense to you. Again, chat with me! Let's develop a plan together.
Where do you see the future of food going? 3D printed? Unfortunately, more processing is inevitable to feed the world's population. My personal biggest concern is the amount of packaging we are using; I wish we can find a 'new' plastic that doesn't hurt our environment as much as the plastics we are currently using.
What is the difference between Judy and the other instructors? I don't know :) Please tell me what you think by April.

Wednesday, January 6: Lesson 1

I like to finish Lesson 1 today...

January 8 to 13: Lesson 2

We watched this video for fun:

Friday, January 15: Lesson 2, Emulsion, protein water

I plan to finish Emulsion, Protein, and Water today.

No more required reading in Lesson 2

That's it. No more required reading. The two articles posted in Lesson 02 are no longer required.

What about FAT???

I still really want you to know about the chemistry behind margarine (and the formation of 'trans' fat). I will prepare a new side page with exactly what you will need to know by Monday.

Monday, January 18: MARGARINE!!! IMPORTANT!!!

You need to know the relationship among the different types of fats in margarine for the midterm and probably for the final!!!

Poem on Pain au Chocolat


img_0978.jpg Chocolate croissant with flaky and moist interior and melting chocolate

Bking in the oven
The aroma is so sweet
The scent welcomes you in
The warm feeling of heat

Flaky as you bite
Moist as you chew
The chocolate in sight
Will melt in your mouth too

Delicious, can't get enough
Even after a ton
Though it may be tough,
Now you're ready for another one

-by Sabrina-

Fermentation of soy sauce in two types of production facilities:

Small scale production

LARGE scale production

Cheese Making

This is a pretty easy to follow clip, a bit funny and has all necessary science content needed for FNH 200

This shows less science, but the machine is shinier than those in the clip above.

This video is even clearer than the one above, but I feel there is less science content.

Friday, March 18: Team Day

Monday and Wednesday, March 21 and 23: Lesson 10

Wednesday, March 23: Project Due

This is indeed a very good introduction/summary of how irradiation works as a food preservation technique.

Friday, April 15, 3:30 pm

Wednesday, April 20, 3:30 pm: Final Exam

  • Complete PeerWise #3 Question Answering (answer 6 and comment on two per person)

Location: Scarf Room 100

All lessons 1 to 13, 2.5 hours


  • roughly 70 to 85% of mark will be from multiple choice questions (individual and team)(Judy promised to have less than 55 questions)
  • roughly 15 to 30% of mark will be from short answer questions (individual only)
  • You will have 90 minutes to complete the individual components (multiple-choice questions and short answer questions). You must stay till the end of the 90 minutes for the team component. If you finish before 90 minutes and checked over all the answers three times, it is best to use the time to take a nap. If you really really need/want to study for another course, you may study text-based materials after submitting your own FNH 200 102 exam and with permission from Judy.

Memory Aide: 11 by 8.5 double sided

Creating Useful Memory Aide

First of all, I hope that you recognize the use of a memory-aide (or commonly known as cheat sheets) is a way to practice your summarizing skills. Beyond lists and tables of facts,

  • Are you able to identify the key information and concepts in the lessons?
  • What information is needed to help you understand and integrate the concepts?
  • How can you arrange your notes so that you can find what you need during the exam when you are under tremendous pressure?

I really like to the 5R method introduce in the last minute of this video: Record, Reduce, Recite, Reflect and Review.

Exam: 7 tips for making great study notes:

Visual learners often find it useful to connect concepts using concept maps:
