Investigating the Presence of Starch, Glucose, Protein, and Fat in Food Sample – IGCSE Prescribed Practical

Investigating the Presence of Starch, Glucose, Protein, and Fat in Food Sample – IGCSE Prescribed Practical

In this practical investigation, we will be exploring the presence of important nutrients such as starch, glucose, protein, and fat in different types of food. By using simple chemical analysis techniques such as Benedict's solution and Biuret reagent, we can test for the presence of these nutrients and gain a better understanding of the nutritional composition of different foods. These tests can help us make informed decisions about our diets to ensure that we are consuming a balanced and healthy diet. Through a step-by-step guide and the use of equipment such as test tubes and a water bath, we can carry out these tests with ease and interpret the results to gain insights into the nutritional value of different foods.
