Common sugar tests, like Somogyi or Benedict test, focus in a simple reaction, the reduction of a part of the sugar skeleton. Simple sugars, like glucose, have an alpha-avaliable conformation, which lets Somogyi or Benedict reactives interact with the molecule and change it chemically.
Some sugar foods have a tasy sugary flavor but lack real sugars. Scientists found molecules that taste sugary, but don't have the chemical structure and properties of real sugar (saccharoses).
Otherwise, some real sugars, lack this reactive site, because it may be bounded with another molecule and isn't free to react with the test reactives.

How do you test for sugar in foods?
benedict's test.
What indicates a test for catalase production is positive?
sugar
Is staphylococcus aureus triple sugar iron test positive?
Acid ferment
Why does glycoproteins reacts positively with Molisch reagent?
Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.
Is it possible for certain foods to test positive for more than one organic compounds?
Al foods contain several types of organic molecules except for foods that are essentially chemicals. These would include sugar (glucose, maltose, dextrose etc) and pure ethyl alcohol. Even these would contain trace amounts of other organic molecules as contaminants.
How do you test for sugar in foods?
benedict's test.
Will sugar alcohol test positive for alcohol on a drug screen test?
No
What foods would test positive for carbohydrates?
Bread, pasta, and cereal would certainly "test positive" for carbohydrates.
What indicates a test for catalase production is positive?
sugar
After hydrolysis did sucrose give a positive test with fehlings test why orwhy not?
After hydrolysis sucrose did give a positive test. It reduces sugar that has hemiketal and hemiaetal in it.
Why did a solution of saliva and oats test positive with benedict's test and iodine test if the oats alone tested positive only in the iodine test and the saliva alone was negative for both?
polysaccharides and simple sugar
Is staphylococcus aureus triple sugar iron test positive?
Acid ferment
Why does glycoproteins reacts positively with Molisch reagent?
Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.
Which foods would have the following nutrient test results?
C- candy, table sugar, sugarless gum
Will hydrolysed dextrine give positive response to Benedict test?
Yes, it should. Benedicts test will be positive for reducing sugars, and since glucose is such a sugar, and would be a product of dextrin hydrolysis, you should get a positive result with Benedicts reagent.
What is a Positive test for a reducing sugar results?
it will change from light blue to green to the orange and then to cherry red.
Can eating certain foods help with depression?
Foods like fish, fruits, veggies, water, and fiber rich foods can enhance positive moods. Other foods like alcohol, sugar, and caffeine can have a negative effect on moods.
