Which one of the following best explains why there was a difference between the food test result and the food packaging?The test was only for non-reducing sugars, they need to test for the presence of the other types of sugars. This could explain why there was a difference between the food label and the food test results.The student did not add enough Benedict's reagent therefore a positive result might have been missed.The test was only for reducing sugars (e.g. glucose) and does not detect the presence other types of sugars, namely non-reducing sugars. This could explain why there was a difference between the food label and the food test results.There was not enough of the sample when adding Benedict’s reagent.I DON'T KNOWSUBMIT ANSWER

We use chemical reagents in food tests to identify the presence of biological molecule.Identify the correct colour change you would expect, when a substance tests positively for the presence of glucose after Benedict's solution is added.Blue to purpleOrange-brown to blue-blackClear to cloudy emulsionBlue to brick redI DON'T KNOWSUBMIT ANSWER
