Megjegyzések:	Considering that proteins are the most important and the most expensive components of victuals, we can see the importance of the fast and exact definition of their amount and quality. The purpose of our research is developing a protein content diagnosing method, which can be performed even in low-mounted laboratories, without the need of the most expensive instruments, however being able to provide proper results corresponding the Kjeldahl method used in well-mounted laboratories. During our laboratory tests we chose three of the several well-known protein analysing methods. We determined the protein content of wheat, corn, soy and sunflower seeds with the methods of Kjeldahl, Biuret and Nessler. Most laboratories use the Kjeldahl method or automatic instruments based on that for analysing the protein content, therefore these results came as a resembling base compared the results of the two other methods used in our tests. The Biuret and Nessler methods are based on spectrophotometric measurement, which fundamentally provides rapid and accurate measurement. As the preparation of the samples for these methods is complex and takes too much time, we decided to use the Kjeldahl disruption. In total, we can state that our examinations ended with success: comparing the two spectrophotometry based methods to the Kjeldahl method, we received almost the same results. The dispersion of the results is the lowest with the Kjeldahl method, but the precision of the Biuret and Nessler methods is still acceptable.
