Concentration of squalene from shark liver oil by short‐path distillation

Investigations on the concentration of squalene from shark liver oil using short‐path distillation are presented and compared to alternative techniques. Aspects of chemical composition analysis are discussed as well as physical and sensory properties. A product is obtained with squalene purities above 97% at feed flows of up to 7 kg/h and temperatures between 185 and 230 °C. In order to assure product quality, a simple refractive method is applied. Based on the presented study, scale‐up to industrial production is performed taking into account the complete process for obtaining an acceptable product with a neutral odor.
