Could you name the four important food tests?

Here are four important food tests, along with the substances they test for:

1. Benedict's Test: Detects the presence of reducing sugars, like glucose and fructose. (A positive test results in a color change from blue to green, yellow, orange, or red.)

2. Iodine Test: Detects the presence of starch. (A positive test turns the solution from yellow-brown to blue-black.)

3. Biuret Test: Detects the presence of proteins. (A positive test turns the solution from blue to violet or pink.)

4. Emulsion Test: Detects the presence of fats and oils. (A positive test results in a milky, cloudy solution.)
