Food analysis

Bread, milk, nuts, sweets, meat or vegetarian products - the variety of foods is enormous. They differ in origin, composition and processing. The demands on food analysis to determine nutrients such as proteins and fats or fibers and additives are correspondingly high.

Cereals as a staple food

Cereals provide carbohydrates, fats and proteins - important macronutrients that can be reliably analyzed using suitable methods. The fiber content also plays a central role in grain analysis and can be determined by fiber extraction. The "Arbeitsgemeinschaft Getreideforschung e. V." offers recognized standard methods for this.

Animal products and plant-based alternatives

Milk from cows, goats or sheep is the basis of numerous products such as yogurt, cheese or quark. It contains proteins, calcium and probiotics. The nitrogen and protein content is usually determined using the Kjeldahl or Dumas method. The fat content can be analyzed using hydrolysis and solid-liquid extraction. This also applies to vegan alternatives such as soy or oat drinks. The LFGB and ISO guidelines are decisive.

For meat, fish and meat substitute products, the focus is on protein and fat analysis. Fish fats in particular, including omega-3 fatty acids, are considered valuable. The LFGB and the AOAC provide specifications for analysis.

Sulphur dioxide in food

SO_₂ is used as a preservative in wine, dried fruit or juices, but is harmful to health in high quantities. Compliance with international limits can be checked by analyzing sulfur dioxide, for example by steam distillation. AOAC and DIN provide guidance.

Each food sample requires a specific analysis method. C. Gerhardt rises to the challenge and provides suitable solutions.

The right solution for different needs

We are particularly well positioned in the field of nitrogen and protein analysis. We offer partially and fully automated solutions according to Kjeldahl and Dumas and can therefore meet a variety of requirements. With our systems, you can also carry out every step of fat analysis according to Weibull-Stoldt - from hydrolysis to solid-liquid extraction. We are also specialists in the field of fiber extraction. From crude fiber to ADF and NDF, we cover it all.

We have also developed special applications for sulphur dioxide analysis. On the one hand, we offer a space-saving alternative to the optimized Monier-Williams method and, on the other, a particularly time-saving method with our VAPODEST systems. As you can see, we are also able to cater to different requirements and provide you with the right solution.
