Determining the glucose concentration in sprite

Table 1.

Sugar content in soft drinks experiment

Below is a example of a time vs. Table 2. As tested by the laboratory, there was only a small variation in total sugar content within each of the three soft drinks and the fountain samples had a similar amount of total sugar to the bottled samples. Equipment and materials In addition to the Rodeostat open source potentiostat , we also used the following equipment and reagents. Considering that the average American drinks 50 gallons of soda and other sweetened beverages each year 11 , it is important that we have more precise information regarding what they contain, including a listing of the fructose content. Label each of the remaining beakers with the name of the soda to be tested. Add 50 ml of flat soda to the labeled beaker. Summary Measuring glucose concentrations in liquids with the Rodeostat and glucose test strips was very easy and could be a useful teaching method for teaching electrochemistry, potential-step voltammetry and biosensors. The Dr. Current rate of electron transfer at a given time is directly proportional to concentration as shown by the Cottrell Equation.

Add 50 ml of flat soda to the labeled beaker. Review Your Results The numbers you recorded were your data. Considering that the average American drinks 50 gallons of soda and other sweetened beverages each year 11it is important that we have more precise information regarding what they contain, including a listing of the fructose content.

Therefore, our results have important implications for estimates of fructose consumption and of the relationship between fructose consumption and metabolic health. The unexpected glucose detected in the Vitamin Water and the fructose detected in the Red Bull could potentially be explained by the inclusion of HFCS.

It will give the mass of sugar, in grams, and the volume of the soda, in milliliters. Use the graph you drew to figure out how much sugar is in each soda. It also has a relatively low oxidation potential.

The overall consumption of added sugar is of concern as is the composition of the sugar.
