Nutriswiss, one of the leading refiners of edible oils and fats in Switzerland, uses a special combination of physical refining processes to effectively purify organic oils and optimize their taste. After treatment, the oils are virtually free from process contaminants (3-MCPD, glycidol, trans fatty acids). Mineral oil residues, plasticizers, free fatty acids and other contaminants are effectively reduced while micronutrients are preserved.

As a contract manufacturer, Nutriswiss refines a wide variety of oils for the food industry. Its state-of-the-art processes enable the gentle refining of oils in compliance with European organic guidelines and other certifications such as Demeter, Bioland and BioSuisse. In this way, oils that would be of limited suitability for further processing or trade due to intense flavours, coloration or exposure to environmental and transport contaminants become safe ingredients.

Unlike conventional physical refining at high temperatures, which creates process contaminants and destroys valuable micronutrients, the thermal load in “mild refining” processes remains comparatively low. Therefore, the process is also suit-able for sensitive raw materials such as omega-3-rich seed oils like rapeseed or linseed oil, algae oil or other specialty oils.

Organic oils can also contain residues of mineral oil. During organic cultivation, contaminants can originate from exhaust gases, for example, or can enter the raw material through contact with machinery and transport circumstances. With “mild refining” technologies, Nutriswiss succeeds in purification without the formation of process contaminants such as glycidol and 3-MCPD. Thus, highly pure and sensory-neutral products can be produced in a gentle manner. •
