What is the definition of food-test?

A food test is a scientific method used to identify the presence of specific nutrients or compounds in food samples. Common tests include the Benedict's test for reducing sugars, the Biuret test for proteins, and the iodine test for starch. These tests involve adding reagents to the food sample and observing any color changes or reactions that indicate the presence of the targeted nutrient. Food tests are essential in nutrition science, food quality control, and educational settings.
