Kjeldahl Method
The Kjeldahl Method is a classical analytical procedure for determining the total nitrogen content of food products, developed by Johan Kjeldahl in 1883. By measuring total nitrogen and applying a conversion factor specific to the food type, the method indirectly determines crude protein content. Kjeldahl remains the official standard method for protein determination in foods, nutraceuticals, and animal feeds worldwide.
