For more than 165 years, Crespel & Deiters has been shaping the refinement of plant-based raw materials. The journey began with wheat, a versatile and high-performance resource that laid the foundation for our expertise across food, feed, pet food and industrial applications.

Refinement of Plant-Based Raw Materials

Experts for Starches & Proteins

Building on this heritage, Crespel & Deiters has continuously expanded its capabilities and today works with a broad spectrum of plant-based raw materials. This long-standing evolution has created a deep, differentiated understanding of plant-based refinement, positioning the company as a recognized specialist with strong technological and application expertise.

Today, Crespel & Deiters transforms renewable plant-based materials into functional solutions that enhance processes, improve product performance and support sustainable, future-oriented business models. Driven by technological excellence, profound application know-how and close collaboration with customers, we deliver measurable, practical benefits across Food, Pet Food, Feed and Industrial Solutions.

Wheat Perfected by Refinement

Wheat is one of the earliest cultivated crops, and today it remains the most widely grown cereal worldwide, cultivated across more than 220 million hectares. Its unique structure and composition make it an outstanding raw material for functional refinement.

To unlock this potential, we rely on prime-quality, 100% GMO-free wheat, sourced primarily from German agriculture and supplemented by selected European origins. Using state-of-the-art processing technologies, we utilize up to 99% of the wheat grain, transforming it into a wide range of high-quality, functional ingredients.

This integrated approach allows us to maximize the value of every grain, ensuring efficient resource use, consistent quality and a sustainable, high-performance supply chain.

Refined wheat ingredients

The composition of the wheat grain enables a multitude of refined ingredients. The natural structure of the wheat grain makes it an ideal raw material for refinement.

Wheat starch is the core product at Crespel & Deiters and a central building block for many of our solutions and a wide range of applications. Through targeted processing, we enhance its functionality, improving gelling behavior, binding capacity and texture performance in food and industrial products.

Wheat proteins, including gluten, deliveroutstanding functional performance in food applications, particularly in plant-based and high-protein products. Our wheat proteins provide excellent water absorption, elasticity and texture, making them a key component in vegan and vegetarian formulations.

165 Years of Expertise Extended to other raw materials

Rice Flour

Perfect for texture and crispiness

Rice flour is a well-established ingredient used in the production of extruded products such as crisps and crumbs. Its mild taste, excellent processing properties and consistent texture make it ideally suited for a wide range of food applications.

In extrusion, rice flour delivers uniform expansion behavior, enabling the production of light, crispy structures with controlled porosity. Its neutral flavor profile, makes it ideal for seasoned end products. . It can also be combined with other ingredients such as proteins, fibers or functional additives. In addition, its light color enhances the visual appeal of coatings.

Corn Flour

Stability and flavor for multiple uses

The high process stability and availability of corn flour make it a reliable raw material for industrial extrusion processes, ensuring reproducibility and efficiency in production. Known for its stable expansion properties and ability to form crispy, even textures, it is ideal for creating both fine and coarse structures depending on the formulation and desired product.

Its mild, slightly grainy taste adds a familiar flavor to many applications, while still being neutral enough to act as a carrier for flavors, spices or coatings. Its natural yellow color imparts a warm, appetizing appearance to extrudates.

Whey Protein

Protein enrichment the crispy way

Due to its nutritional profile and high customer acceptance, whey protein is a key ingredient for versatile extrusion solutions within the growing high-protein product market. When combined with starchy raw materials, whey protein helps create crispy, protein-rich structures with controlled texture and density. Its mild dairy taste integrates well into a wide variety of applications, offering high protein content without compromising flavor or mouthfeel.

Milk Protein

Balanced nutrients for active nutrition

Milk protein combines casein and whey protein fractions to offer a balanced nutrient profile and versatile technological properties. In extrusion, milk protein contributes to the formation of stable, structured protein crispies with defined crunch and controlled density. It enhances texture, porosity and mechanical stability, making it ideal for high-protein snack applications.

Pea Protein

Protein with consistent functionality

Pea protein ensures stable processing in extrusion and creates a smooth texture without any elastic bite. Pea protein has a natural, light-yellow color with a subtle pea taste and odor, making it easy to incorporate into a wide range of applications.

Pea protein applications by Crespel & Deiters delivering consistent extrusion performance, smooth texture without elastic bite, light-yellow color, and subtle flavor, enabling stable processing and flexible use in a wide range of plant-based food applications.

Fava Beans Protein

Defined crunch and structure

Fava bean protein is suited to textured, protein-rich extruded products where structure and crunch are key. It adds stability and mechanical strength, supporting crispy structures with defined texture and controlled porosity, especially when combined with starches.

The mild, cereal-like flavor with subtle legume notes can be easily balanced through formulation so that it can be combined with flavors, seasonings or coatings applied during downstream processing.

Potato Starch

Light textures and controlled expansion

Potato starch supports extruded crisps and crumb applications. Its physical properties allow precise control of expansion, texture and mouthfeel. In extrusion, it creates very light, airy and crispy structures, increasing porosity and reducing bulk density. Neutral in taste, it supports stable processing and consistent product quality at industrial scale.
