A
scientist says that an invasive weed could be used as a protein source
for animal or human food.
gorse
bushes that have invaded many landscapes could produce enough protein
to feed millions of people, according to the leader of a Scottish
government research programme.
The
suggestion by Prof Wendy Russell, at the University of Aberdeen,
comes from research on the protein content of invasive plants that
are currently sprayed with toxic herbicides or burned to keep them under
control.
Gorse
contains 17% protein she
said
“Gorse was
fed to cattle at times when crops failed in the past, so we think
protein from these
plants could be used as animal food. If protein isolates are
produced in the correct way, so to be safe, they could be considered
as human food in the future.”
“The
whole point about gorse is it is actively being removed from marginal
lands – it’s something we can gain protein from at no extra
cost,” she said. Gorse is widespread trhroughout Australia.
