==Key Stage 3==
===Meaning===
The '''Benedict's Test''' is a method for finding whether a food has sugar in it.

===About the Benedict's Test===
: Glucose and Fructose can be detected with the [[Benedict's Test]].
: Sucrose cannot be detected with the [[Benedict's Test]] unless you first react it with dilute hydrochloric acid.

=====Method=====
1. A sample of food is dissolved in water.
2. The solution is added to blue Benedict's solution in a boiling tube.
3. The solution is kept at 90°C for up to 10 minutes.
4. A colour change indicates the presence of glucose or fructose. If they are present the solution will eventually turn brick red or brown.
