Proteins are no longer just a component of sports nutrition - they are now among the central functional raw materials in food production. Whether in convenience products, beverages, sweets, dairy products, or meat alternatives, proteins provide structure, functionality, and a more attractive nutritional profile. Our focus report shows how different proteins differ and what options we can offer you.

Few food raw materials are as versatile as proteins. The differences in taste, functionality, color, solubility, protein content, and amino acid profile are significant and are crucial for successful product development. Additionally, requirements for origin, labeling, sustainability, and cost-efficiency play an equally central role in the selection process.

Today, manufacturers face the challenge of using proteins not only as a nutrient source but also as functional building blocks - doing so as neutrally in taste as possible, technologically efficiently, and in a way that fits the product's positioning.

Our shining stars are the white fava bean isolates from European production. These practically tasteless proteins are impressive due to their high functionality, excellent solubility, and a light color. In addition to a finely ground version, we also offer a completely soluble version - ideal for even the most demanding applications. 

 

If required, we would be happy to send you samples and further information.

Protein concentrates

Protein concentrates are typically produced using a mild, purely physical process. Depending on the source, the protein content varies between 50 and 70%. Compared to isolates, concentrates contain more starch, fibers, fat, and minerals, thus reflecting more of the original plant matrix.

These properties make concentrates particularly attractive for applications where natural ingredients, sustainability, and high cost-efficiency are required, such as in baked goods, snacks, and meat and dairy product alternatives.

Protein isolates

Isolates are characterized by a high protein content (up to 90%) and particularly high functionality. The purification processes reduce unwanted accompanying substances, improve solubility, and ensure a more neutral taste and a lighter color. They are ideal for applications with high demands on the technological quality and quantity of the protein.

Possible applications include alternative products, clean-label products, bars, and other functional foods and beverages.

Protein hydrolysates

Hydrolysates are enzymatically broken-down protein isolates. This targeted hydrolysis can either improve specific functional properties or increase solubility. Our hydrolysates were specially developed for clear solutions: they are completely water-soluble, foam very little, and are therefore ideally suited for use in beverages and liquid applications.

Textured Vegetable Proteins (TVPs)     

TVPs (Textured Vegetable Proteins) are primarily used to provide structure in plant-based or mixed meals. This is usually done with dry extrudates, and our product range specializes precisely in this. We offer TVPs in a variety of shapes, sizes, and colors, such as granules, strips, chunks, or as powder.

TVPs are used in meat and meat alternative products, fillings, and protein-enriched ready meals and can be flexibly adapted to taste and texture.
