Testing for simple sugars

Today we going to do another test, it's about food like to determine whether it contains simple sugars. I put all information I learn about this test on my blog and I hope u like.


Aim:  To test a sample of food to determine whether it contains simple sugars, complex sugars and protein sugars.


Hypothesis: 

• I think that egg is going to be simple sugar.
• I think that bread is going to be a complex sugar.
• I think that Apple is going to be a protein sugar.
• I think that the potato is going to be a complex sugar.
• I think that glucose is going to be a simple sugar.
• I think that milk is going to be a simple sugar.

Equipment:  Water bath, test tongs, Benedict's Solution, a sample of food



Method:  


1.  Place about 2 ml of the sample into a test tube and then add 5 drops of Benedict's Solution.
2.  Heat with a water bath until it changes colour, Do not boil.



Result:

For the apple, bread, and potato they change colour to look at the picture and u can see what colour it is.

For the egg.gluecose and milk, u can see that the colour stay and didn't change and there is white on the top and the bottom is blue.

The three top picture is egg, milk, and glucose.
The three bottom picture is apple, bread, potato.

Conclusion: 

As u can see in the photo some of them are the normal colour and some of them mixing colour, the one who is in the photo is m partner we work together as a group to do this testing. After we have done the testing I take photos of each of our testing and put it on our blog so u can see what have we done.
