FeyeCon combines widespread expertise in fat & oil ingredients with experience in clean and sustainable CO₂-based processing technologies. This is not that strange since CO₂ is a compound that is in principle lipophilic. With CO₂ we extract, refine, micronize and formulate fats & oils for a variety of products. For example, Unilever who we assisted with the development of margarines. FeyeCon offers solutions for obtaining effective products both in functionality, with superior quality without compromising costs.
CO₂ is one of the few solvents which is Generally Regarded As Save (GRAS). Conventional extraction methods require a purification step due to traces of solvents. Others use heat to extract, compromising the extract’s quality and creating trans-fats. FeyeCon’s CO₂ extraction method offers the low temperature and non-toxic alternative. After extraction CO₂ evaporates completely, leaving pure extracts identical to their origins. Because CO₂ technology is versatile and tunable, we can create streams, which are otherwise hard or impossible to obtain. Moreover, our methods are also used to valorize oil waste streams especially oil distillates.
FeyeCon’s clean CO₂-based processes for oil refining offer the environmentally-friendly opportunity as they operate with no chemicals, at low temperatures (c.a. <40⁰C) and therefore prevent unwanted reactions. We can achieve this through extraction, but more elegant is CO₂ assisted cold pressing. In the later we dissolve CO₂ to the oil rich phase and filter the material. This increases the yield and can still be considered as a cold press oil. It also leaves a better flavor and extracts more anti-oxidants from the material.
UPGRADING OILS WITH UNIQUE CO₂ FRACTIONATION TECHNOLOGY
FeyeCon is one of the few companies in the world that uses the novel CO₂ fractionation technology for upgrading oils. By separating the different types of components present in the oil, we offer tailored processes for desired compounds. The technology can be compared with distillation, with the difference that we are not limited by vacuum, meaning we can have as many theoretical stages as we design (HETP) and of course no heat, just 40⁰C or something similar. Additionally, the process is clean and gentle, operating in an inert atmosphere, preventing the oxidation and formation of trans-fats. This improves the health profile and performance of the oil. CO₂ fractionation allows the creation of technology solutions for the next generation cosmetic, food and nutraceutical products with superior quality.
IMPROVED FUNCTIONALITY: ENZYMATIC TRANS-ESTERIFICATION
Chemical esterification is one of the major reactions used in food industry to modify the physical and functional properties of natural fats and oils. Traditionally, this process occurs at elevated temperatures (~200⁰ C) or with the presence of enzymes which make the process not very efficient. Instead, FeyeCon offers the possibility to eliminate those harmful/inefficient conditions by introducing CO₂-assisted esterification. At considerably lower temperatures we use CO₂ as an inexpensive, non-toxic solvent that does not leave any residues in the final product. In that way FeyeCon’s process improves the utility of edible oils for a variety of applications.
TEXTURIZING FATS: INNOVATIVE MICRONIZATION METHODS
Our CO₂ micronization technology is the friendly method for creating three-dimensional porous particles crystals from fats and waxes, delivering an array of textures. The powders are stable, free-flowing and easily dispersed into a final application mixture. Furthermore, formulation is simplified and energy efficient, thanks to the low temperature mixing.
With our CO₂ micro-encapsulation process, FeyeCon successfully protects valuable fat & oil ingredients without altering their functional properties (e.g. nutritional value, bio-availability) even upon further processing such as UHT or steam. Contrary to traditional methods, our mechanism results in a well-protected ingredient with an extended shelf-life. Additionally, the technology enables increased concentration for volatile oils, flavours and nutraceuticals.
