They determine the food's ratio of protein, carbs, and fat per weight and then just multiply (protein and carbs have 4 calories per gram, fat has 9).
But apparently, before they figured that out, they would actually burn the food and measure the heat output. After all, a calorie is nothing but a measure of heat energy. http://www.straightdope.com/classics/a3_097a.html

How do they figure out calories on a package of food?
