Stock up on Easter Sale Items

It's Easter time! Of course the true importance of this holiday is a personal one, it is also a good time to stock up on items that will keep your budget down for next year.
Things you will find at great prices this week include:

  • Ham Bones are a great way to demonstrate stock. They could also be used in cooking dried beans demonstration.
  • Pork products. No matter how much I hate the smell of cooking meat, my students still insist on sneaking bacon into every creative project. I hope this trend ends soon! :) The Iowa Pork Checkoff offers vouchers for purchasing pork for classroom use.
  • Peeps are great for demonstrating how a microwave works.  They are so much more fun than plain marshmallows. (And they are CHEEP! this time of year ;) )
  • Sugar! My local HyVee has it priced for just $.99 for 4 lbs, limit four per customer.
  • Flour! HyVee has it for $1.68 for 5 lbs, no limit!
  • Not a sale item, but fun to note that pies cost $10 on sale! What a great fundraiser or business idea!

Sensory Perception Experiments

Students performed a variety of experiments showing the importance of sensory perception and how it applies to food appeal.

First, students evaluated how color and appearance affected perception of flavor.
I purchased three flavors of sparkling water and poured them into six clear cups. One of each of the flavors was clear and one of them had a drop of food coloring in them. 

I didn't tell students ahead of time what the objective of the experiment was. Students had the liquid poured into a dixie cup. Their partner timed from the time they took a drink to when they identified the flavor of the beverage.

As predicted, students correctly identified the clear liquids although it took them some time. They identified the blue drink as "Blue Raspberry" although it was strawberry. The drink that took the least time to identify was the lime drink that was also colored green.

Then, just for fun, we tried some jellybeans. We put them in our mouth without looking at them, but plugging our noses. We couldn't identify the flavor until we unplugged our nose. This demonstrated the difference between taste and flavor, as well as the importance of aroma.
