Testing for simple sugars
Testing for Simple Sugars (Benedict's Test)
Aim
I want to find out how to test for simple sugars.
Simple sugars are carbohydrates that are quickly absorbed by the body to produce energy. They are also classified as “simple” because they contain only one or two units of sugar or saccharides. Also referred to as simple carbohydrates, these sugars are found naturally in a variety of foods that we consume daily.
Equipment
Safety glasses
Bunsen burner
Test tubes
Test tube tongs
Benedict's Solution
Food sample
Method
Place about 2mL of the food sample into a test tube and then add 5 drops of Benedict's solution and 5ml of water
Gently heat the test tube over a blue flame. DO NOT BOIL!
Results
A positive test for a simple sugar results in the Benedict's Solution changing from a blue colour to a yellow colour to an orange/red colour.
Conclusion
…..
Extra for experts
Two different types of sugar exist: simple and complex. Complex sugar takes longer for your body to break down and is healthier for your body. This type is found in natural carbohydrates such as whole grains and fruit. On the other hand, simple sugar is broken down by your body quickly and causes energy ups and downs. This type of sugar includes refined and processed sugar found in table sugar and added to many sweets. Consuming an excess of simple sugar comes with numerous health problems

Give two examples of simple sugars and complex sugars in your daily food.
At what times of the day may you need simple sugars?
Do you think that it would be wise to eat simple sugars before bed? Why/why not?

NZ crest T1W8
Why won't they just call it a shield? Because in 1956, some of the features surrounding the shield were changed. The crest was actually made in august 26th and the year was 1956 so that was ages ago. And the NZ crest is actually on the new Zealand passport. And the NZ crest was also on the police clothing. the people that were on the NZ crest were queen Elizabeth and there was a chief on the NZ crest.
