Nutrtional information can either be calculated in a lab by using high tech equipment that measures each of the attributes. Or information can actually be calculated by using a nutritional program.  This program has data that has been collected over many many years.  A food processor builds the recipe in the program and all preset data is calculated resulting in a nutrtional panel.

Your reply did not answer my question.  I could have written that myself.

If that didn't answer your question, would you like to clarify what you mean exactly? There are different tests for each attribute.  I don't believe you want me to go into detail for each test, as that is lengthy and boring and also there are multiple methods.  For instance, you can use a method for testing the amount of fat called the Goldfisch fat extraction.  Although, many labs now use automated way like a piece of equipment called Foss.  
But as mentioned earlier, many food companies actually do NOT even lab test their food.  They use a computer program to generate the data.  
Hope this is helpful, if not feel free to clarify what you are looking for.
