proteinhaltigem

Proteinhaltigem is a German adjective describing substances that contain a high proportion of protein. The term combines Proteine (proteins) and haltig (containing or rich in), and is used in nutrition, food science, and related fields to characterize products or ingredients with notable protein content.

In nutrition and food labeling, proteinhaltig foods are those that contribute significantly to daily protein intake. The protein content is usually expressed as grams per 100 grams or as a percentage of total energy or weight. Standards for what constitutes “protein-rich” vary by country and context, but the descriptor is commonly applied to products designed to support muscle maintenance, growth, or satiety.

In product development and culinary contexts, proteinhaltigem describes ingredients and finished foods that help meet dietary protein goals. Plant-based proteinhaltige ingredients such as soy, pea, lentil, and rice proteins are frequently used to fortify meat substitutes, dairy alternatives, and ready meals. Animal-based proteinhaltige foods include dairy, eggs, lean meats, and fish.

Beyond food, the concept can appear in biomaterials and food science research, where proteins are a focus for gels, films, or scaffolds. Quality considerations for proteinhaltige products include protein type, amino acid composition, digestibility, and processing effects on protein structure.

Examples of proteinhaltige foods and ingredients:

- Dairy products (milk, yogurt, cheese) with added or naturally high protein

- Meats and seafood

- Legumes and seeds (beans, lentils, chickpeas, soy)

- Nuts and grains with elevated protein content

- Processed protein ingredients (whey, casein, pea protein, soy protein isolates)
