High-grade CO2-Extraction of Grains and Seeds

Gentle extraction of grains and seeds

Due to low oil content of raw materials, the only option to generate oils out of grains is often times extraction. Via a standard press method, these oils cannot always be detached completely from the plant matrix. If organic solvents are to be avoided, CO₂-Extraction will be the preferred method in this case!

Sunflower seeds

Sunflower seeds out of certified organic cultivation are processed gently and supply precious, plant-based protein with a min. content of 55%. It is generated from peeled organic sunflower seeds, via special cold pressing and micro-milled. By means of our scCO₂-technology, contained fat is almost removed completely afterwards, which in parallel increases protein content further. Emulgation capability and the mild, nutty taste of the sunflower protein have to be highlighted specifically… Discover more on Heliaflor

Rice bran

Via our CO₂-Extraction, rice bran oil is extracted from seedlings and seed shells, which were separated during rice production. CO₂-extracted rice bran oil possesses a brownish to greenish color and features a characteristic fragrance. Besides a balanced share of oleic, linoleic and palmitic acid, rice bran oil contains Gamma-Oryzanol, tocotrienols, tocopherols and squalene.


Oat is a well-known, versatilely used cultivated plant and contains, amongst other things, sterols, triterpenoid saponins like Avenacin and Avenacosid. Moreover, oat is gluten-free and associated with positive aspects by consumer. Despite the high degree of familiarity of oat, its precious oil, extracted via the supercritical CO₂-technology, is less known and seldom. As an example, the golden yellow oat oil is used in skin-soothing formulations.
