You can measure protein and calcium in citrus juice.
An iodine would be one way of mesuring starch. You mentioned an absorption test. What would you be measuring inthis test?

The easiest way to test for calcium is with a specific ion elcetrode and meter. Hopefully your science department will have one. They are available from a number of sources - Cole-Parmer (
http://www.coleparmer.com), Hach Inc. (
http://www.hach.com) or Beckman
(
http://www.beckman.com/resourcecenter/l ... echome.asp).
Each of these sites has information on meters and electrodes.

Tooth decay is the result of bacterial action on food sources in and between the teeth.
Bacteria are controlled by reduced pH (acid conditions).
You may want to read up on the reaction of bacteria to the components of orange juice.
Protein would serve as a food source for bacteria in the mouth.
Calcium may increase the severity of tooth decay because of its role in the formation of biofilms. You may want to do a Google search of tooth decay, calcium and biofilm.
