Food without fields -plant cell technology for a sustainable food supply
Heiko Rischer
VTT Technical Research Centre of Finland Ltd., Finland
D
espite enormous intensification, food production methods have basically not changed for hundreds of years. Plants are farmed in
fields, harvested at the end of the season and transported to factories for further processing or straight to the markets or grocery
stores where consumers buy them. Alternative approaches are desperately needed due to the huge challenges ahead. The global
population will need 60% more food by 2050 but global warming and exhaustion of the soil will render agriculture more difficult
in many current agricultural areas. At the same time, the production of materials and energy will compete with food production
for land use. Agriculture accounts for 20–25% of all global greenhouse gas emissions and relies on chemical fertilizers from fossil
resources, and harmful agrochemicals. Urbanization drives food production into cities in order to reduce transport costs and waste.
There is a need to produce larger quantities of healthier food, with less resources and land, closer to urban consumers. Plant cell
cultures (PCCs) are totipotent and cultures of almost any species can be grown in bioreactors instead of fields, enabling contained
and fully controlled year-round biotechnological production. PCCs are used for the commercial production of phytochemicals for
pharmaceuticals, pigments, cosmetics and additives. The biomass is usually extracted for single components, but the value of the
whole material as food has been neglected. PCCs contain nutritionally promising combinations of proteins, carbohydrates and lipids,
enriched with vitamins and health-promoting compounds. Additionally, they exhibit technological process ability relevant for the
food industry as well as suitable sensory qualities. The presentation aims at highlighting the great potential of PCCs for a sustainable,
secure and healthy food supply and the state-of-art in research and development.
