∙ 13y agoFor glucose Benedict's or Fehling's test is performed.
- Benedict's test: 1 ml sample is mixed with 1 ml of Benedicts solution and the heated upto boiling. If the colur changes to brick red then it confirms the presence of glucose.
- Fehling's test: similarly 1 ml Fehling's solution I & Fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. If the colour changes to brick red the it confirms the presence of glucose.
For more precise description cf. wiki-answers on 'benedict' or 'fehling' test

Why did glucose test strip change colour after saliva was added?
chemical reaction
If you wanted to test a piece of food to see if it contained protein which chemical would you use?
buiret
What test that would be able to distinguish between glucose and ribose?
The Bial's test is applied.
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.
Would glucose give a positive result with the Biuret test?
No because glucose does not consist of two or more peptide bonds
What chemical can be used to test for clucose?
Benedict's solution can be used to test for glucose.
How do you measure glucose in food?
You have to buy glucose test strips and either dip it in liquids or rub it against fruits or veggies. If the food is dense (ex. honey), then mix it with 10 ml of water and insert test strip.

What did Helen Murray free invent?
" chemical test for differentiating leukocytes from erythrocytetes" "indicator for detecting glucose"..........
What test that would be able to distinguish between glucose and ribose?
The Bial's test is applied.
What happens if I ate a candy bar before a fasting glucose test?
You rather destroyed the test. Fasting glucose is used to test for diabetes and your indulgence with a candy bar would invalidate the test results.

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.
How can you test food to see if there are toxins or chemicals in it?
with chemical strip
What types of food would test positive result for carbohydrates proteins fats?
Any food that has carbohydrate, protein, and fats can be shown positive for those food test. It is basically a chemical reaction that indicate the presence of food component by a specific color formation.
What is a glucose blood test for?
To test for the amount of sugars (glucose) in the blood.
Would glucose give a positive result with the Biuret test?
No because glucose does not consist of two or more peptide bonds
