New industrial processing techniques are
enabling us to obtain valuable proteins, antioxidants and oils from salmon and
rapeseed waste. These extracts can be used in health foods, nutritional supplements
and skin care products, Phys.org reports.
Researchers and industrial partnerships
around the world have been developing new, industrial processing techniques.
Using rapeseed and fish as their basic raw materials, they have succeeded in
producing entirely pure fractions, free of organic solvents or additives. Such
processes will ensure that valuable proteins, antioxidants and oils contained
in waste fish and rapeseed raw materials are not discarded.
Norway produces farmed salmon worth several
billions every year. But much of this raw material is discarded during
production. Only 50 percent of the fish mass remains once off-cuts such as
heads, dorsal fins and offal are removed.
Industrial rapeseed is produced across
huge, bright yellow fields. But only the black seeds are used to produce oil,
and large volumes of chemicals are used in the oil extraction process. The
remains of the seeds are used for animal feed and as a source of bioenergy.
SINTEF has headed one of the project's
seven work packages with the aim of developing a so-called
"environmentally-friendly process technology for the exploitation of waste
raw materials from fish filleting for human nutrition and skin care
applications."
"We have carried out two processes
involving salmon and Nile perch. We have analysed both the oil and proteins
from the fish waste raw materials, as well as waste from rape and mustard
seeds," says Rasa Slizyte at SINTEF Fisheries and Aquaculture.
In their work, the researchers have
employed advanced NMR (nuclear magnetic resonance) techniques, which enable
them to monitor the freshness of the fish raw materials in storage. Meanwhile,
research partners in Spain have developed a technique for incorporating and
stabilising fish proteins in cosmetic creams.

The EU project APROPOS has had as its aim
to demonstrate the value inherent in waste food resources which are currently
used mostly for animal feed.
