WebEnergy from Protein: 5 g x 4 kcal/g = 20 kcal = 20 Cal. Convert to kJ. 20 Cal x 4.184kJ/Cal = 83.68 kJ = 84 kJ. Step 3: Think about your result . For the snack food in this example, most of the energy is coming from fat first, then from carbohydrates and finally from protein when these three sources of energy are considered. WebMeasurement of Food Calories The potential energy value of foods and the energy exchanges of the body are expressed in terms of the calorie, which is a heat unit. By definition, the large Calorie, or kilocalorie (kcal), is the amount of heat required to raise the temperature of 1 kg water 1oC (from 15o to 16o). This unit is always used in ... Webfor food labeling is to determine the amount of each component in the food (i.e., proteins, fats, carbohydrates, alcohol, organic acids) and add up the amounts of energy for each component.
