The document describes food tests to identify different components of food including starch, glucose, protein, and fat. For each test, it lists the steps of the procedure and expected results. For example, to test for starch one would add iodine solution to the food on a plate - if the color turns black, it indicates the presence of starch. It then provides an example showing senbei (rice crackers) testing positive for starch, glucose, fat, and protein. The document also includes information on the nutritional content and journey of rice crackers through the digestive system.
