Researchers Extract High Value Nutrition from Salmon and Rapeseed Waste

Published Date : Mar 11, 2015

Scientists worldwide are engaged in the effort to make optimum utilization of the available resources. Recently a group of scientists discovered a new technique of industrial processing that makes it possible to obtain valuable proteins, oils, and antioxidants from rapeseed and salmon waste. One can use these extracts in nutritional supplements, health foods, and a range of skin care products. 

The project adopted by EU APROPOS aims to demonstrate the value present in the waste food resources which are at present only used as feedstock for animal. Industrial partnerships and researchers around the world are currently developing new and advanced industrial processing techniques that will allow the generation to realize the value inherent in their food waste. The school of researchers has been successful to develop an organic free solvent or additive using salmon fish and rapeseed as their basic raw material. The discovery of the process will ensure that the nutritional value present in the waste rapeseed or fish is not discarded. 

A farm in Norway produced salmon worth several billions every year. But it discards much of the raw material used at the time of production. Reports highlight, only 50 per cent of the actual mass of fish remains, after the heads, offal, and dorsal fins are cut off or removed. Similarly industrial rapeseed is produced in huge quantities, across bright yellow fields. But for the production of oil, only the black seeds are used, while the ones remaining are used as animal feedstock or at times as a source of bio-energy.  

The project headed by SINTEF showcases how the wasted raw materials can be exploited using environmentally friendly ways to harness nutritional values that can be used across multiple purposes.
