The Swiss edible oil and fat specialist, Nutriswiss, is expanding its refining operations with new short path distillation (SPD) equipment. The process removes contaminants and isolates fatty acids at particularly low process temperatures. At the same time, it prevents the contaminations of food products and preserves micronutrients. With this new technology, the company is able to achieve previously unattained levels of quality and overcome a key hurdle for manufacturers.
Since June 2020, Nutriswiss has been using SPD to refine and produce pure, high-quality products. The process gently removes pollutants such as pesticides from palm, rapeseed and other crude oils without forming contaminants in situ owing to the low thermal load applied.
Because of the extremely low pressures used in SPD, high temperatures can be avoided. The distance from the evaporating flask to the condenser is short, so there’s very little pressure loss compensate. Valuable components such as micronutrients are preserved and yields of essential omega-3 fatty acids, for example, can be maximized. At the same time, hydrocarbons (MOSH/MOAH), pesticides or plasticizers such as DEHP derived from mineral oil are significantly reduced or even removed. Thanks to the application of this method, Nutriswiss is setting new standards in terms of the purity, quality and nutrient content of the oils they offer.
