Storing Berries. Traditional ways of storing berries:
What are they and why is each effective?
Before most villages had freezers, we packed blueberries in lots of
sugar, and they didn't spoil. Why is this? You would think sugar would
make them ferment more quickly.
Berries/colors. Why are berries bright colors? What is accomplished
by this? what happens to the seeds of the berries we eat? What is the difference
between the seeds of the berry and the surrounding sweet berry material?
How resistant to acid are the seeds? What would happen if this were not
so?
Fish spoil. Why do fish spoil @ 35° and meat is able to
keep for a long time at that temperature?
Freezer burn. What is "freezer burn" on foods in a freezer,
and how can it be avoided? Experiment
Salt/salmon bellies. How does salt preserve salmon bellies in
a barrel? What chemical and biological phenomina are happening?
Drying fish. How does drying fish preserve it? Test different
brine solutions for salmon strips. Which do people prefer?
Coffee test. Most people say campfire coffee is the best. Run
a taste test on campfire coffee, percolated coffee, and filtered coffee.
Can people taste the difference? Why is there a difference? If so, why?
Bread mould. Does homemade bread mould faster than store-bought
bread? What does this tell you about store bought bread?
I have an idea now.
How do I present my experiment? Go.
