Highly precise, matrix-independent protein determination in food analysis

The determination of the total protein content according to international labeling laws is an essential tool for quality control and protein declaration in the food industry. Protein content can directly correspond to product properties and classifications, e.g. dough properties, foam formation, or the taste of beer, and can therefore be a decisive factor for product quality and price. In all application areas of food analysis, highly precise, matrix-independent protein analyses are required. 

Cost-effective food analysis

Protein determination is one of the key analyses performed in the food industry. It demands analysis results delivered with the highest precision and accuracy at an economic price. Our dedicated nitrogen and protein analyzers fully meet these requirements, ensuring cost-effective and eco-friendly food analysis through high-temperature combustion according to Dumas. Combined with our patented, resource-saving EAS REGAINER® technology, maintenance time and cost in protein analysis are greatly reduced. With the use of CO2 as inexpensive carrier gas instead of helium, the cost per analysis on our rapid N exceed® nitrogen and protein analyzer is as low as 0.25 €*, including chemical, electricity, and gas costs.

High sample flexibility in food analysis

Our nitrogen and protein analyzer rapid MAX N exceed represents the industry standard in ease-of-use for measuring a combination of liquid and solid sample types. The upright crucible design means that measuring up to 5 g of solid samples or 5 ml of liquid samples is equally as simple and requires no additional materials or handling. Because the analyzer can measure such high weights, samples can be quite inhomogeneous, such as fruit juices and milkshakes, and still yield accurate and reproducible results. 

Dietary fiber analysis

In the determination of dietary fiber content, a critical step in this method of food analysis is the determination of the protein content of the final digestion residue, which is a mixture of fiber, protein, ash, and filter aids. With its robust autosampler that facilitates automatic ash removal with large crucibles, our nitrogen and protein analyzer rapid MAX N exceed is especially suited to this analysis. New methods using plastic filter bags also present no challenge. Integration of the rapid MAX N exceed with dietary fiber analysis is an uncomplicated, cost-effective solution. 

Food authenticity

Fraudulent adulteration or mislabeling of premium and protected foods can be detected by means of stable isotope analysis. For more information on our instrumentation for food authenticity and origin testing, please visit our food authenticity page.
