What foods below would test positive for starch in the presence of iodine? Question 8 options:

a steak

a hard boiled egg

noodles, bread, or crackers

chicken

The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.

Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.

Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.
