Here's a solution to the fish burps of Omega-3 capsules.

Insect oil is a possible new source of the healthy omega-3
fatty acid. Insects make fatty acids by nature and can live on organic
waste. Wageningen University examines which insects can best be used for
oil and what their optimal diet should be.
Insects are already used as a source of protein for man and beast. In
the protein extraction process also oil is extracted. This insect oil
is currently thrown away. That is a shame, proves researcher Daylan
Tzompa Sosa of Wageningen University.
Fatty acids
In her PhD-research, Tzompa Sosa looks at milkfats. Out of curiosity,
she once did similar fat analysis with oil that was left over after
protein extraction of insects by a lab colleague. “The oil appeared to
contain a lot of fatty acids, both saturated and unsaturated.” In
addition, Tzompa Sosa demonstrated that the oil can be extracted in an
environmentally friendly way, giving also the highest return and the
best quality oil compared to other processes. Tzompa Sosa extracted oil
from for instance meal worms, beetle larvae, crickets, cockroaches,
grasshoppers and soldier flies. “All the oils smell differently, some
nicer than others”, the Wageningen scientist says.
Fish
The industry is interested in sustainable fatty acids like omega-3
and lauric acid. The main source for omega-3 is currently fish. It is
added to the feed of cats and farm raised salmon, to foodstuffs and put
in capsules. “Cats die when they get a full vegetable diet without these
additives. That is why they normally eat meat. Farm raised salmons get
wild caught fish or fishmeal instead.” Also humans need to take in a
certain amount of fatty acids. Lauric acid (also to be found in coconut
oil for example) is supposed to have bactericidal and virus obliterate
qualities. Furthermore, the use of insect oil in for example cosmetics
is obvious.
Properties
To research breeding, diet and processing of insects for oil, the
Wageningen fat researchers are working together with entomologists and
bio based experts of Wageningen UR. One of these researches concerns an
analysis of the different fractions in oil and their properties, because
these fractions have different liquid and solid phase. Also a risk
analysis of use of the oil for man and beast will be done.
