My aim is to figure out what nutrients are present in different foods
Test foods -
- Egg
- Bread
- Apple
- Potato
- Glucose
- Milk
Hypothesis:
I think Bread will be a complex sugar, I think eggs will be a complex sugar,I think lollies will be a simple sugar,I think the apple will be a complex sugar,I think milk will be a protein and last of all i think the potato will be a complex sugar.
Method for complex sugar.
- Put the sample into the test tube.
- Then add 2 drops of iodine.
- The bread turned black.
- The Apple turned black
- The Potato turned black.
- The Glue Coast turned brown.
- The Milk turned brown.
- The Egg turned brown.
Method for simple sugar.
- Put the sample into the test tube.
- Then add 5 drops of Benedictines
- Then heat it up.
Before heating the ingredients -
- The potato stayed blue.
- The Apple stayed blue.
- The glue coast stayed blue.
- The egg went orange.
- The bread stayed blue.
- The milk stayed blue.
After heating up the ingredients-
- The bread stayed blue.
- The egg Stayed blue.
- The milk stayed a little bit blue.
- The potato went orange.
- The apple went orange.
- The Glue coast went orange.
- Place about 2mL of sample into a test tube and add 5 drops of sodium hydroxide.
- Add 5 drops of copper sulfate.
- Shake the test tube side to side
- The Apple has no protein.
- The potato has no protein.
- The egg has protein.
- The glue coast has no protein.
- The bread has no protein.
Conclusion: The bread was a complex sugar,The apple was a complex sugar,The potato was a complex sugar,The glue coast was a simple sugar,The egg was a simple sugar,The milk was a simple sugar.
I was right about the bread,Apple,Potato, being a complex sugar. I was right about the glue coast,but I was wrong about the Milk and Egg.
Discussion: I found out that most of the proteins are from animals and the different types of simple sugars and complex sugars.
