What type of food will give a negative Iodine test and a positive Biuret Solution test?
An iodine test is used to test for the presence of starch (or polysaccharides, specifically amylose or amylopectin). A Biuret solution test is used as an indicator for peptide bonds within proteins. Therefore, if you get a negative iodine test and a positive Biuret test, you would probably be testing a animal food source (beef, chicken, pork). Overall, any food that doesn't have starch present within it would be appropriate to use. Hope this helps!
How do you prepare biuret solution?
What you mean by the performance of Biuret Test? This method just can tell us that if there is any protein contents but it can't give any exact figure of the type of protein. The Beer's law is obeyed to at least 10 g per dl. So actually what your question point of? What you mean by the performance of Biuret Test?

How do you test for each type of organic molecule in foods?
The Qualitative tests for each of the macronutrients are as follows: Carbohydrates - Iodine test and/or Benedicts test Proteins - Biuret test Fats - Ethanol (Emulsion) test
Is it advisable to use just one type of indicator to determine the nature of an unknown solution?
No; every test must be confirmed by another test.
