What are the applications of the Kjeldahl nitrogen analyzer in industries such as food and feed?
What is a Kjeldahl nitrogen analyzer?
The Kjeldahl nitrogen analyzer is an automatic intelligent detection instrument designed based on the classic Kjeldahl nitrogen determination principle. It is widely used to detect the overall content of ammonia nitrogen and protein nitrogen in grains, oils, dairy products, beverages, feed, soil, fertilizers, sediment, and chemical products. It is an important physical and chemical analysis instrument for product quality testing.
Application fields for Kjeldahl nitrogen analyzer
1. Protein determination
The Kjeldahl nitrogen analyzer can be used in national standard methods, such as the determination of protein in food, crude protein in feed, crude protein in vegetable oil, and gluten protein powder.
2. Determination of nitrogen
The Kjeldahl nitrogen analyzer can also be used in national standards, such as the determination of non protein nitrogen content in milk and dairy products, the determination of nitrogen content in starch and its derivatives, the determination of nitrogen content in soil, the determination of total nitrogen content in compound fertilizers, the determination of ammonium nitrogen content in fertilizers, and the determination of urea. In addition, there are also cases of using a Kjeldahl nitrogen analyzer to determine the ammonia nitrogen content in water, natural rubber nitrogen content, and ammonium salt content in soy sauce.
3. Determination of volatile base nitrogen
Some people also use the Kjeldahl nitrogen analyzer to determine the volatile base nitrogen content in tuna meat, meat, and fish meal. This means using the Kjeldahl nitrogen analyzer to determine the volatile base nitrogen content and uncertainty evaluation in aquatic products, meat, and their products.
In addition, there are also applications of Kjeldahl nitrogen determination instrument to determine the content of formaldehyde in watery hair products, the content of sulfur dioxide in day lily, volatile alkali in caprolactam, etc. From this, it can be seen that the application range of Kjeldahl nitrogen analyzer is very wide.
