By burning a dried sample of it in a device called a "bomb calorimeter" with pure oxygen and measuring how much heat is released by the temperature rise in a water jacket around the "bomb".
They get the food and light it on fire and put it under a test tube of water. How much energy is in the food depends on how much the water has heated up

I have no clue.
To calculate the energy available from a food, multiply the number of grams of carbohydrate, protein, and fat by 4,4, and 9, respectively. Then add the results together and that should be your answer.
The amount of energy that you can get from that food. We get our energy from calories. And when we burn energy, we burn calories. So, we measure calories to see how much energy we will get from that particular food. This tells us how much of that food we should eat, compared to how much energy we expend.
how much energy the food molecules have
That means how much energy it has.
Yes, They didn't find out much
