Development of new valuable dietary fibers from rosehip press cake

Innovation is consistently influencing the food sector.

At SanaBio GmbH, in partnership with the Anhalt University of Applied Sciences, we present an innovative project aimed at upcycling rosehip press cake, a by-product of oil extraction, as a significant source of dietary fiber.

Our project is co-funded by the European Union.

The vision behind the project

We are working together with Anhalt University of Applied Sciences to develop an advanced technology that can produce fine dietary fiber fractions (<75 µm) from the press cake of rosehips.

These fractions, rich in essential nutrients such as calcium, magnesium, potassium, and vitamin B6, will thus be suitable for various applications in the food industry.

We aim to upcycle rosehip press cake into a beneficial component for food products that support a healthier diet.

Objectives and research

Fiber extraction. We test grinding and separation techniques to produce fine fractions. These advanced methods will allow us to extract high-quality dietary fiber efficiently.

Incorporation into food recipes. We intend to use these nutritional fine fractions in a wide range of products, including pastries, sausages, sauces, smoothies, and fish products.

Sustainability. Our strategy focuses on upcycling a by-product into a valuable resource, thereby reducing environmental impact. Moreover, we are supporting more sustainable practices in food production.

Why rosehip press cake?

Rosehip press cake has a rich composition that includes more than 70% insoluble fiber, 5-10% protein, about 3% residual oil, and 6% carbohydrates. Its characteristic fibrous structure can cause specific technical difficulties, but we are testing efficient shredding possibilities by using innovative techniques such as cutter-based grinding methods commonly used in meat processing.

Our strategic partnership

Our expertise in organic raw materials and market analysis, together with the University of Anhalt's advanced research facilities and technological know-how, helps us get closer to achieving our goals. We believe that our collaboration innovates the food sector, especially in the development of a proprietary fiber extraction process.

By upcycling a by-product into a valuable resource, we are creating healthier food options, and we are preparing the ground for more sustainable practices in the food sector.
