The importance of the protein transition
Four drivers for the protein transition
1. We don’t have enough protein to feed the world. Not true.
2. Animals are inefficient: everyone should eat vegan. Not true.
3. Plant-based alternatives have a lower footprint. Partially true.
4. Plant proteins are of lower quality. Partially true.
4 trendy myths

total global
protein supply

Inequitable distribution

In Europe:
▪ >50% from
animal sources
▪ all countries have
excess protein
In Africa:
▪ >50% from plant
sources
▪ many countries
with insufficient

4 technology routes to
increased protein
availability
Improved crops
▪ Few breeding initiatives have
focused specifically on protein.
▪ Collaboration between food
technology and plant breeding
presents an opportunity.
▪ Pulses are an efficient protein
source for European
cultivation.
For example, faba beans have
high potential yields per hectare
but a noticeable (off)flavour in
application.
Innovative aquatic production systems
▪ The oceans cover 71% of the
earth’s surface but provide only
7% of our protein.
▪ Smart oceanic farms can combine
energy and food production.
Aquatic protein crops like seaweed
and microalgae still require energy-
intense downstream processing;
technology breakthroughs are
needed.
Energy & aquaculture
With fish & crab nurseries
Biosynthesis and recombinant proteins
▪ Fungal, bacterial, and yeast
protein sources can be grown
on a variety of substrates and
thereby decouple production
from resources.
▪ These sources can be
integrated into no-waste
energy-food production
systems.
Mycoproteins have an appealing
fibrous texture and are already
accepted by consumers.
Reduced food loss and waste
Protein recovery from agricultural side
streams:
▪ increases European supply,
▪ strengthens the economic basis for
farming,
▪ provides unique proteins with
functional and nutritional benefits.
Potato proteins are already available
and sugar beet leaf proteins are in
development.
sugar beets: 80 ton/ha
leaves: 40 ton/ha →
European food loss & waste
The highest volume of European primary
production losses come from vegetables
and roots & tubers.
The highest volume of
processing losses come
from oilcrops.
The biggest
contribution to
GHGs is from
bovine meat
waste.
PRODUCTION HANDLING/STORAGE PROCESSING DISTRIBUTION (POST)-CONSUMER
Protein l&w

In Europe 14M
tonnes of protein
are lost or wasted
per year.
Globally,18M
tonnes of protein
from oilcrops are
lost per year.

Thank you!
Especial thanks to co-authors Prof. Emely de
Vet, Prof. Luisa Trindade, Dr. Hannah van
Zanten, and Prof. Louise O. Fresco for shaping
this vision.
The data, diagrams, and images presented
today represent the work of many colleagues,
working with numerous public- and private-
sector partners. We thank them for their
willingness to allow us to communicate about
their work.
