- Expectation of this course
- Something about you that you like me to know
If you didn't attend class on Jan 2, please fill out an index card. I like to know who you are, though I will not have time to add your contribution to the word clouds below. Thanks.
Here is a graphic representation of the academic background of students in FNH 200 this term:
Students in FNH 200 like these foods:
And they like these brands:
Friday, January 4, CDN Food Systems, Stats Canada Link[edit | edit source]
We continued our discussion on the Canadian food systems in Lesson 1.
We ended our class with a prediction of recent food consumption pattern. Here is what we predicted:
Here is the latest link to the Food Statistics 2009 Highlight page. Please scan through the page and pay special attention to the first bullet point:
I also created a summary of food available pattern in the last several decades. See table on left and double click the image to get a larger view. You do not need to know the exact data.
Washington State Apples: Controlled Atmosphere Storage webpage
Monday, January 7, Food Trends in 2009, Lesson 02 Food Colloids[edit | edit source]
We reviewed food trends.
We spent most of the class on food colloids: sol, gel, emulsions, and foams. I gave out some jello samples and attempted to foam some milk to illustrate foaming.
Wednesday, Jan 9, Carbohydrates[edit | edit source]
We began with some marshmallows.
The rest of the class was all about the many forms of 'sugars'. We watched a video on the making of sugar glass:
- I finally know how to embed a youtube video on UBC wiki!!!***
We finished the class with some sour lemon drops and soft caramel.
Questions from Students[edit | edit source]
A couple students stayed behind class and asked more questions.
1) How does high fructose consumption (particularly through high fructose corn syrup) affect our health?
A good question (because I don't know the answer and never thought of this). I should actually worry about this as my daughter LOOOOOOVES fruit and she would have a higher-than-usual intake of fructose!!!
After doing some quick reading on the internet, I no long worry about any negative effect on high fructose consumption.
However, I'm still interested in reading more. Could the student who talked me on Wednesday come talk to me again? I like to learn more about the 'acid' you mentioned. Thanks!
2) Maillard browning reaction: how does it really work?
You may want to visit an old course page of FNH 301 (Food Chemistry) to find out more details of the chemical reactions of Maillard browning reaction:
Friday, Jan 11, functionalities of FATS and proteins in food[edit | edit source]
We discussed the functionalities of fats and proteins in food.
When it comes to fats, think about croissants , especially 'pain au chocolat' and french fries.
When it comes to protein functionalities, I like you think about the roles of milk proteins in milk, latte, and cheese.
Monday, Jan 14, Trans-fat[edit | edit source]
Try to answer this question:
How do we convert liquid veggie oils to a solid margarine?
Additional and optional information:[edit | edit source]
Trans-fat in oils before and after deep-frying: http://www.sciencedirect.com/science/article/pii/S0308814609002775

Wednesday, Jan 16, Water Water Everywhere[edit | edit source]
Friday, Jan 18, Aroma, Colour, Vitamins and Minerals[edit | edit source]
After we discussed aromatic compounds, colourants, vitamins and minerals in foods. We started a quick introduction on sugar substitutes. I asked the class to read the labels of a few common sweeteners that can be found at coffee shops.
Mid-term Teaching Feedback (not completely summarized yet as of Jan 18)[edit | edit source]
I then asked for your feedback on my teaching. I asked you to complete the following two sentences:
- I'm still confused about ____________________.
- I like/don't like your teaching because _____________________.
Here is a summary of your feedback and my responses:
|I'm still confused about...||My responses:|
|[Blank] x 4||Really? Don't hesitate to let me know when you are confused. :)|
|what is expected; depth of question x 3||I will go over the learning outcomes of each lesson in the future. I also showed a couple sample question on Monday, Jan 21|
|colloidal dispersion: gels, emulsions, foams, etc x 3||I briefly went over this on Monday. Please come see me. I found it easier to explain face-to-face rather than typing in front of a laptop. Please come see me.|
|what is required on the exam and what is optional.||Everything, except a few tables, will be considered to be on the exam.|
|fat part of Lesson 2||Example|
|what is the core point of this course? Food processing? All the ingredients?||The focus of lessons 2 and 3 is on the ingredients. The second half of FNH 200 focuses on the processing.|
|adding triglyceride to margarine||Ummm... please make an appointment to see me. I'm very concerned when you say 'adding triglyceride...'. It would be easier to explain face-to-face.|
|introducing trans-fat in margarine||I will explain this in class again.|
|what do we need to know on nutrition labels?||You do not need to know nutritional labels yet. Labeling regulations will be discussed in Lesson 4.|
|chemicals in food that affect health. Sometimes too much details to know and I'm not sure which is the right concept we should study or understand||All of those included on the lesson pages|
|exactly what you want us to know from your slides||I don't use slides; I only show the wiki pages and I expect you to know almost everything on the wiki pages.|
|what kind of questions you want us to make for PeerWise||Multiple-choice questions|
|do I need to know everything in required readings?||No, I've changed 'required' readings to 'recommended' readings.|
|PeerWise; what kind of questions you want us to make for PeerWise||Multiple-choice questions and I hope that your teammates will be able to help you with PeerWise|
|when it comes to scientific names and structures of compounds since I'm a non-science students.||You don't need to remember the structure of the carbohydrate-related compound. I do expect you to know the differences among saturated, cis-unsaturated and trans-unsaturated fats.|
|protein functions||Gels, emulsion, foams and enzymes|
|group work||I understand that it is challenging to work with a group of complete strangers. I'm doing my best to help you bond with each other. Please trust me that if you maintain a positive attitude and show the willingness to share, you will do fine in your team.|
|do I need to know everything in required readings?||No, I've changed 'required' readings to 'recommended' readings.|
|some specific terminologies||Again, please come ask me. It's my job to help you understand and I love my job :)|
I like your teaching because:
- fun stories x 5
- videos x 2
- food samples x 8
- entertaining x 2
- [no reason provided]
- it leaves me a lot of interest in food processing
- relaxing (through tasting foods) while learning
- interactive x 4
- interact with everyone
- humour helps me remember
- bubbly personality
- makes me crave chocolate croissants :)
- feel comfortable asking questions
- simplify the topics
|I don't like your teaching because...||My responses:|
|it sometimes can be not as productive, spending too much time on one topic. I only want to know and learn what we have to learn for this course content.||Please let me know which topic I spent too much time on. FNH 200 is a foundation course. There is so much more about food and its science than what is discussed in FNH 200. I will try to find the right balance between 'covering' enough and 'stimulating' interests.|
|I have no idea what I'm learning.||Lesson 1 is an introduction to the Canadian food system and Lesson 2 provides a basic understanding of the chemical structure of foods.|
|You have lots of spelling mistakes and grammar errors.||Please help me correct them on the wiki pages.|
|Where to find all the class info... it would be easier to keep everything on just one site.||The course VISTA is THE site to visit. Due to the nature of the different activities I included for this course, I am using a few different web-based tools. I am very aware of the challenge and I try to make it clear on the course syllabus.|
|[I like your teaching, but] I prefer powerpoint slides. There isn't enough space on the wiki printouts to write notes.||Oh, I can help you find some space.|
|easily off topic; would like to follow more closely to testable materials||This is not quite my teaching style. I will try to stay close to core materials as much as possible. Oh... this is not going to be easy as there are so many interesting stories to share...|
|there aren't slide; I don't know what is super relevant for exams.||Concepts that I spent more time, related with more personal stories are concepts that I personally care about. The amount of time I spend on each topic forms a direct relationship with the relevance and chance of it being on the exam.|
|What you said is not from the notes||I like to include some personal stories in the lecture to make the course content more relevant. The wiki pages provides all that you need to know for the exams.|
Monday, Jan 21: Review[edit | edit source]
Sample mid-term exam questions:
When making Jell-o, the pectin in the Jell-o package dissolves in hot water and solidifies upon cooling, forming:
A. a liquid in polysaccharide emulsion
B. a liquid in solid gel
C. a gas in solid gel
D. a gas in solid foam
E. None of the above
Which image below shows a by-product during the conversion of liquid vegetable oil to spreadable margarine?
A. [Picture of a saturated fatty acid]
B. [Picture of a cis-unsaturated fatty acid]
C. [Picture of a trans-unsaturated fatty acid]
Wednesday, Jan 23: Sensory, Assignment and Research Project[edit | edit source]
We will discuss how we perceive food quality using our senses and how we test food quality using our senses.
We will go over the assignment and research project.
Friday, Jan 25: Team Meeting Day[edit | edit source]
- Meet your teammates in person
- Meet your TA (Tina, Keely and Lennie)
- Discuss, finalize and contribute three questions (and answers) to PeerWise
- Brainstorm potential topic for the research project
Topic Selection Suggestions[edit | edit source]
- Choose something most members like
- Do a preliminary exploration on the topics before you commit to it
- Depth is better then breath; focus on an aspect of a particular topic rather than 'everything' on a topic
- Processing or making topics can easily become very shallow, as a recipe/cookbook with step 1, step 2, step 3 type procedures. Teams wanting to work on processing should remember to include some scientific explorations in your project
Once your team has come to a topic that is of interest to most member, remember to post on here: http://wiki.ubc.ca/Course:FNH200/Team_Projects
Suggested seating arrangement on Friday. After you 'find' everyone and if you wish, you could move to somewhere else, just notify your TA.
Monday, Jan 28: Assignment and Lesson 04[edit | edit source]
We went over the assignment and started thinking about food regulation (lesson 04).
Wednesday, Jan 20: Midterm and Group Exam[edit | edit source]
I thought it went really well. As you all know, I'm big on peer learning. I am excited to see how many of you engaged in discussion, and sometime heated debate!, during the group component of the midterm.
If you have any insight, feedback and comment, please let me know. Leaving your scribbles on a piece of paper on the table up front is all you need to give me feedback! Thanks in advance.
Midterm Stats[edit | edit source]
Individual average = 64% Group average = 90%
The most challenging questions are:
- Francois Nicolas Appert
- BUBBLY, moist bread
- What ARE in spreadable margarine?
- DESIRABLE protein functions
How Did PeerWise Help?[edit | edit source]
Friday, February 1: Grading[edit | edit source]
Egg Grading[edit | edit source]
Beef Grading[edit | edit source]
Monday, February 4: Regulation decision making[edit | edit source]
Finishing Lesson 4
Wednesday, February 6: Lesson 5 (and maybe 6)[edit | edit source]
Midterm 01 Grade[edit | edit source]
Many of you asked to change the way I calculate the final midterm grade, from 85/15 (group/individual) to 80/20? I have decided not to.
In addition to those reasoning I provided on Vista, I am also considering this data:
Afterall, I also 'believe' that it's those of you who actively engaged in the debate and discussion immediately after the mid-term benefitted most intellectually.
Peer Evaluation: ipeer.elearning.ubc.ca[edit | edit source]
Your formative peer evaluation will be available on Wednesday, Feb 6, at ipeer.elearning.ubc.ca, due on Feb 15.
The goal of this midterm evaluation is to give each member a channel to voice your appreciation/concern of your teammates midway through the project, before it's too late. Your evaluation and comment will be kept anonymous from each other. Grades and comments will be released on Feb 25.
Grades received from this formative evaluation will not affect your own final project grade; however, your own participation will impact your project grade.
Selling Homemade Canned Foods[edit | edit source]
We had a few questions regarding the selling of homemade canned foods. I couldn't find anything from BC (let me know if you found something), but there was a couple sites from Alberta:
Basically, one can only sell canned jam, jelly, pickles and relish.
