Analysis of Food Dyes-Step 2 - Taking the spectrum of each dye for identification -Step 3 - Part 1: Preparing a set of dilutions of the standard dye -Step 3 - Part 2: Measuring the absorbance of the standard solutions -Step 4 - Part 1: Determining the concentration of the unknown dye -Step 4 - Part 2: Determining if the drink exceeds the ADI guideline for Blue #1 |
Qualitative and Quantitative Analysis of Food Dyes >> Step 4 : Part 2
Qualitative and Quantitative Analysis of Food Dyes
Now that we have calculated the concentration of Blue #1 dye in our drink to be 2.2 x 10-6 M, we can determine if this exceeds the acceptable daily intake (ADI) of Blue #1 set by the Joint FAO/WHO Expert Committee on Food Additives.
The following tutors are a step by step walkthrough that show the details on how to solve the above problem.
