Your EEI could look at the fermentation rates of glucose and fructose separately - keeping everything the same except the independent variable of initial concentration. It may be sweetened with sugar or artificial sweetener.
The method can be easily found on the internet and may even be in your textbook under a heading of "analyzing fertilizer".
It is really just a soft drink, sweetened with sugar or artificial sweeteners. One delicious complication though is that when glucose and fructose are mixed as in the case of fermenting sucrose; or in an artificial mixture the glucose ferments faster than fructose.
