Think about it. Analyze it. Does the result make sense, based on the label and on what is known about the food. Do the results make sense to you.

After doing research it was discovered that rice milk and coconut water do indeed contain protein, although they are not significant amounts. Last, the Sudan IV test for lipids was performed. When a Sudan test is positive, the red dye will disperse and dissolve within the lipid.
