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.

Does starch gives positive result for Benedict test?

Starch is made up of repeating glucose units. Though it is a non reducing sugar, its hydrolysis gives out pure glucose, which is known as dextrose. And glucose, as we know, is a reducing sugar and hence would give a positive result in Benedict's test.


Why sucrose does not give a positive Benedict's test but hydrolyzed sucrose does give a positive beneditcts test?

Sucrose is formed from glucose and fructose.Sucrose is formed from glucose and fructose. Glucose and fructose gives positive test for benedict becuz both of them are reducing sugars whereas sucrose is not a reducing sugar so it gives negative test for benedict. On prolonged heating,sucrose will form glucose and fructose (reducing sugars)which ultimately gives a positive result .

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.


Which is more sensitive the benedict's or fehling's test?

Fehling's test is more sensitive than Benedict's test. It is a more reliable method for detecting reducing sugars, such as glucose and fructose, due to its two separate solutions that are mixed before use, allowing for more accurate results compared to the single solution used in Benedict's test.


What is a good hypothesis for a Benedict's test using glucose?

I hupothesize that ------------- contains the most glucose than other food substance because it is fruit where the glucose mostly found, and it is also involved in the reproductive part.
