what is the method for testing for non reducing sugars?
add 2cm3 of the food sample being tested to 2cm3 of Benedict's reagent in the test tube and filter
then place the test tube in a water bath for 5 minutes (no colour change)
add 2cm3 of hydrochloric acid in a test tube to food sample
gradually add hydrogencarbonate to the test tube to neutralise , as Benedict's reagent doesn't work in acidic conditions
test with PH paper to check solution is alkaline
add 2cm3 of Benedict's reagent and boil in water bath for 5 minutes
positive result: orange to brown
