Wheat is widely grown in China, but the quality is very different, and the quality of wheat determines its economic value to a large extent. Therefore, in the determination of wheat quality, it is often necessary to use an automated Kjeldahl tester to measure wheat grain. Protein content, mainly because protein content is an important measure of wheat processing quality, and protein is mainly a complex nitrogen-containing organic compound, so the automatic Kjeldahl determination instrument is used as a professional instrument for determining the nitrogen content of a sample, and it is used in The determination of wheat grain protein is very suitable.

The automatic Kjeldahl nitrogen analyzer is consistent with the classical Kjeldahl method, but the automatic Kjeldahl nitrogen analyzer is based on the classical Kjeldahl method and has been improved and improved. The determination of wheat grain protein content has the advantages of automatic, time-saving, accurate and reduced environmental pollution. Therefore, the automatic Kjeldahl nitrogen determination instrument is also an important detection instrument widely used in all walks of life.
In the experiment, buckwheat 44 and Yannong 19 were taken as test samples, and the wheat grain protein was measured by Top Kleinner's automatic Kjeldahl apparatus to study the accuracy and accuracy of this method. The results of the nitrogen determination method were compared. The results showed that the recovery rate of total nitrogen in whole wheat flour of Wanmai 44 was 99.38-100.35, and the coefficient of variation of 10 times of protein content in Wanmai 4 and Yannong 19 was 0.60 and 0.84, respectively, which accorded with the tolerance of international methods. The significant test showed that there was no significant difference in the results of protein determination between Wanmai 44 and Yannong 19 whole wheat flour by Kjeldahl and Kjeldahl.
By comparison, we can conclude that the results of the automatic Kjeldahl determination of wheat grain protein are in agreement with the results of the classical Kjeldahl method, and that the automatic Kjeldahl nitrogen analyzer and the classic Kjeldahl Compared with nitrogen method, its advantages are more obvious. It not only has good accuracy and accuracy, but also has the features of simple operation, quick and labor saving, and can be widely used for the determination of protein content in wheat kernels.
