Experiment 18 determining the caloric content of foods problem: experimentally determine the caloric content of food samples (nut, cracker, marshmallow). Lab answers: energy from burning hypothesis if the change in temperature is greater when the water is heated with the use of the fire caught by the food substance, then the energy content in the food substance is higher because the heat energy is greater, since the heat energy is absorbed by the water when the fire is kept under the test .
The food with the lowest energy content per gram was the marshmallow at 3623 j/g this information could be used to help choose foods when more or less calories are needed and to. Before beginning the experiment, you are expected to develop a hypothesis based on what you have learned in this unit using your knowledge of the types and number of bonds found in sugars, fats, and carbohydrates, make a prediction as to which food group has the highest and lowest calorie content.
