Calorific Value of Food. A calorific food value is calculated in terms of kilocalorie, which is defined as the amount of energy required to raise the temperature of one litre of water by 1 degree. The energy value of food represents the value as a fuel to the body.
The caloric values we’re familiar with are actually physiological calories (calories that the body can use). Carbohydrate, protein, and fat are called energy-providing nutrients because the body gets energy from them.
Originally, the calorie content of a food was measured in a calorimeter. A known amount of food, which has had its water content evaporated, was placed in a container surrounded by a known amount of water. The container was sealed, oxygen piped in, and the food ignited.
Calorific value is the amount of heat energy present in food or fuel and which is determined by the complete combustion of specified quantity at constant pressure and in normal conditions. It is also called calorific power. The unit of calorific value is kilojoule per kilogram i.e. KJ/Kg.

The Energy Value of Foods. The energy or colorific value of food depends on amount of energy yielding factors in them. Classically the total energy content of a food was determined using a bomb calorimeter. The food was burned in a bomb colorimeter and the amount of energy released was measured.
Value of food is expressed in calories per gram. A calorie (written with a small c) is the amount of heat required to raise temperature of 1 gram of water by 1oC (more specifically from 15oC to 16oC). The large calories (written with a capital C) or Kilocalarie is equal 1000 calories.
