Food tests

So we tested the bread, patty, and cheese and this is the result:

Tester	Biuret test for Protein	Starch test	Sugar test	Fat test
Bread	None	Yes	Yes	Not translucent
Patty	Yes	None	None	Translucent
Cheese	Yes	None	None	Not translucent

Evidence:

Biuret Test for protein:

Bread-

Patty-

Cheese-

It is not that clear but it turned violet when we tested it

Starch Test

So in this photo, you can see that the bread into blue-black color which means it has starch on it.

Maybe you are confused to the cheese and the patty why some part of it has blue-black color? Does it mean that it has starch on it too? The answer is no. It has parts that it turns into blue-black color because we did not separate properly the cheese and patty on the bread so there is some little piece in the tester. But in the other food test, we ensure that no more small piece of bread or whatever included.

Sugar test

You will know that there is sugar existing in a food when it turns into "brick-red color"

BREAD

 PATTY

CHEESE

Fat test

In the fat tests, I forgot to take a photo in it but I wrote down the results and it's on the upper part of this blog.

Conclusion;

I've learned that every food contains nutrients and it so enjoy to test it. The moment when you are waiting for it to turn into different color or even it doesn't change is so amazing. I've learned that when we are doing the experiment we should always remember that the protection gears are worn by us.
