A home appliance that grows the ingredients for a healthy meal within a week from plant cells is no longer science fiction. VTT Technical Research Centre of Finland Ltd's first 3D-printed prototype is already producing harvests.
VTT and its plant biotechnology research scientists have the vision of developing a home appliance for the markets that makes it possible to grow, say, healthy Finnish berries in a new way. Growing plant cells in a bioreactor is not a new idea as such, but only the latest technologies have enabled the development of a plant cell incubator for home use that yields a harvest within a week.
VTT's first prototype is currently producing a harvest in Otaniemi. The appliance resembles a design lamp and is ideal for keeping on a kitchen table. Researchers are in the process of developing different product ideas in collaboration with consumers, with the aim of commercialising the concept.
"Urbanisation and the environmental burden caused by agriculture are creating the need to develop new ways of producing food - prototype is one of them. It may soon offer consumers a new and exciting way of producing local food in their own homes," says Lauri Reuter, VTT research scientist.
Putting the best parts of plants to use
The idea of the concept is based on growing the undifferentiated cells of a plant rather than a whole plant. In other words, only the best parts of a plant are cultivated. These cells contain the plant's entire genetic potential, so they are capable of producing the same healthy compounds – such as antioxidants and vitamins – as the whole plant. The nutritional value of a cloudberry cell culture, for example, is similar to or even better than that of the berry itself. The taste still needs development: at the moment, it is very mild and neutral.
So far, VTT has used cells from its own culture collection to grow Arctic bramble cells, cloudberry cells and stone bramble cells in the prototype. The bioreactor also enables the production of healthy food from plants other than traditional food crops, such as birch. The development of tailored cell lines is also possible, in which case nutritional characteristics can be developed according to need. On the other hand, the optimisation of growth conditions, such as light and temperature, can also affect the compounds produced by the cells – just like in nature.
