how do food producers, processors and restaurants “measure” how many calories a certain product has? Always wondering that when reading labels / menus.
In: Chemistry
A calorie is the amount of energy needed to raise one gram (mL) of water one degree celcius.
for measuring, you can burn the food to measure how much energy comes off of it using a calorimeter. a calorimeter works by measuring the mass and temperature of the water before and after burning the food to find the temperature difference.
