What chemical is used to test for reducing sugar?
Benedict's solution is used to test for reducing sugar.
Does cucumber contain reducing sugar?
No according to the benedict's test.
How is Benedict's test used to detect reducing and non-reducing sugars?
What_are_the_precautions_taken_while_doing_test_for_reducing_sugars_in_food_using_Benedict_solution
Why doesn't polysaccharides change in the presence of Benedict's solution?
Benedict's test is a test used to determine the presence of reducing sugars. Sucrose is not a reducing sugar that's why its color doesn't change. . .
What is the purpose of hydrolysis test?
There are different uses of it as it may be used to confirm sucrose by hydrolysing and than testing for reducing sugar .
What chemical is used to test for reducing sugar?
Benedict's solution is used to test for reducing sugar.
what is fehling test?
It is a chemical reagent used to differentiate water-soluble carbohydrates and ketone functioning groups. Its also a test for reducing and non-reducing sugars.

What is barfoed test?
The Barfoeds test will allow us to make a distinction between reducing monosaccharides and reducing disaccharides. If the Red tetrazolium test is done first and is positive for a reducing sugar, then the Barfoeds test will tell us if it is mono or di.
What is the test for non reducing sugar?
Benidicts Solution, Wont change colour
Can you test for maltose?
Maltose is actually a reducing sugar so a test for reducing sugar could be carried out.1)Add 2cm3 of Benedict's solution to 2cm3 of maltose solution in a test tube and shake.2)Leave the test tube in a beaker of boiling water for 5 minutes.Observations:1)blue solution to green mixture- conclude that there are traces of reducing sugar2)blue solution to yellow or orange precipitate- conclude that there are moderate amt of reducing sugar3)blue solution to brick red precipitate- conclude that there are large amt of reducing sugar
How do you test for starch or carbohydrate?
take 3cm cubed of the carbohydrate and put in a test tube with 5cm cubed of benedict's reagent. If the carbohydrate is a reducing sugar the solution would turn red. If it contains a non- reducing sugar the solution would remain blue. Then take the non-reducing sugar boil it with dilute hydrochloric acid, cool it and neutralise it with sodium hydrogencarbonate and retest with benedict's reagent if the soultion turns red it means the non- reducing sugar has been hydrolysed to its monomers.If it remains blue there is no reducing sugar present. take 3cm cubed of the carbohydrate and put in a test tube with 5cm cubed of benedict's reagent.

What other test material which can be used to replace Benedict's Solution in glucose test in food?
Barfoed's solution. Glucose as a monosaccharide and a reducing sugar would react positive to Barfoed's Test. Fehlings test (Solutions A and B) tests for reducing sugars but was replaced by Benedict's as a) less hazardous and b) you don't have to mix two solutions.
Why is the Benedict test not exclusive to glucose?
The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
Why doesn't polysaccharides change in the presence of Benedict's solution?
Benedict's test is a test used to determine the presence of reducing sugars. Sucrose is not a reducing sugar that's why its color doesn't change. . .
How will you test for reducing sugars?
Add the substance to be tested to Benedict's solution. Heat to 95 degrees Celcius. If a precipate forms, reducing sugars are president. A significant amount of it will make the precipate orange-red. A little will make the solution green, meaning only a small amount of sugar.
