Bit of a dilema, sugar testing, can you help me out?
Hi, I want to test food colour powder for added sugar, where the maker says it's pure.
The trouble is I have Benedicts solution, however, the powder will turn the solution red because it's powdered colour.
Is there any other way to test for sugar (I don't really want to taste it)?
Thinking logically, it will need to be a reaction to produce some effect other than a colour change?
It's E129 which is an Allura Red Azo Dye. Your thoughts however random or profound are appreciated exceedingly.
