Calculation method of food calories
Generally, it can be found from the food composition table, or it can be accurately measured by calorimeter. Put the sample to be measured into the combustion chamber of calorimeter for complete combustion, and all the released energy is absorbed by water. One millilitre of water rises once at normal pressure, which needs to absorb 4. 187 joules. Record the changes of water quality and water temperature, and make corresponding conversion.
When heating 1 ml (mass 1 g), the heat of food samples is defined as an increase of 4. 1 87 joules for every increase of1Celsius.
(1) staple food: such as rice, porridge and noodles. If 80 kcal is taken as the calculation unit, the calories of 1/4 bowls of rice, half bowls of porridge or half bowls of noodles commonly used in daily life are equivalent to 80 kcal.
