Interview: Chloé Rutzerveld, Designer Who Wants to Grow Healthy 3D Printed Food

The next guest in our interview series is Chloé Rutzerveld, young talented and promising Food and Concept designer, from Eindhoven University of Technology. Chloé is interested in combining aspects of food, design, nature, culture and life sciences in a form of critical design. She uses food as a medium to address, communicate and discuss social, cultural or scientific issues.

Throughout 2014, Chloé worked on a 3D food printing project, titled Edible Growth, to show how high-tech or lab-produced food doesn’t have to be unhealthy, unnatural or not tasteful. Her concept is an example of a future food product fully natural, healthy, and sustainable.

The working principle combines aspects of nature, science, technology and design: multiple layers containing seeds, spores and yeast are printed according to a personalized 3D file. Within five days the plants and fungi mature and the yeast ferments the solid inside into a liquid. Depending on the preferred intensity, the consumer decides when to harvest and eat the edible. While the project is still speculative due to technological limits, the concept is very intriguing.

We recently talked with Chloé about people’s response to Edible Growth, the profession of food designer and new preparation methods and products that could be on our plate one day. Here’s what she had to say:

How did you get the idea for the Edible Growth project?

At the beginning of my final degree project I was thinking of different ways of making eating more efficient and sustainable, starting from the digestive system and actual absorption of food. I needed answers to a lot of questions that were too specific to find on the Internet, which is why I contacted scientists from TNO (Netherlands Organisation for Applied Scientific Research). Instead of answering my questions, they were so enthusiastic about my portfolio and previous food projects that they offered me a graduate spot, where I was challenged to think about new 3D printed food concepts.

We use new technologies as tools to facilitate or enhance the natural

So the 3D-printing part was added when I start working at TNO. I decided to use and combine the research I did in the first part of the semester to create innovative printed food concepts that would suit my vision. I worked together with bio-technologists, scientists and additive manufacturing experts in the process.

The actual Edible Growth idea came from the fact that I wanted this new food technology to be efficient and useful and produce healthy, fully natural food. Printing without additives is very difficult at this point, especially if the material cannot be melted – extruded – and cooled down again like chocolate. So I thought about starting with the basics, the raw material itself. Then nothing can be added, the food does no longer need to be preserved but can be harvested when the consumer wants to eat it. So creating the basics out of raw material with the printer as tool, to let nature do its part. The result: a fully natural, fresh product that transforms and develops in appearance, intensity of smell and taste at the consumers house.

3d printenWhat were the challenges in the development of the project?

I think the most challenging part was the fact that I knew very little about the topics I wanted to combine. 3D printers both software or the hardware and microbiology. Though reading, experimenting and expert meetings the substantive part of the project developed every week, which simultaneously influenced the design part of the edible as well (physical appearance, eating behavior, packaging, thoughts about production and marketing etc.).

What feedback did you have from people? Would they eat any of your 3D printed living biscuits? Or is the idea of eating a mini fungus and watercress planter box still too much?

Until now, Edible Growth is exhibited at the Final Demo Days, during the Dutch Design Week and on Bright Day in Amsterdam. During these expositions I often bring small amuses to let the visitors experience how such a product could taste (see picture below). If I don’t offer them, they often remain untouched. But if I do offer the amuses and give an explanation, almost everybody becomes curious and like to try it. It’s quite funny to observe people passing by and doubting whether or not it’s edible.

Whereas a small percentage of the people don’t like to try the edible, everybody likes the appearance of the product. I receive many comments on how beautiful and delicious the prototypes look. Even chefs from all over the world have approached me for that reason and asked me when the product will be on the market!

'amuse' edible growthHow, in your opinion, can new technologies influence supply chains, eating habits and food preparation methods?

Dependent on the product the 3D-printer makes, the influence of this new technology on supply chains, eating habits and preparation methods might be negligible. But, in case of Edible Growth, the influence is enormous. Because the edible can be printed on demand, with the exact amount of raw materials inside a sterile recyclable packaging, the entire supply chains becomes very short:

– No agricultural land is needed
– No harvest
– No pre-packaging
– No distribution
– No conservatives necessary
– No storage in stores
– No decay or food waste
– < Co² emission

Because the product matures at the consumers house and people can harvest their own product at the preferred stage, they become more involved and conscious of the food they eat. New production methods can make different textures, structures and molecular compositions which might require new ways of eating! I’m very convinced that we can create entirely new products with new production methods that are completely new and surprising, but fully natural and healthy without additives by just using and combining the enormous amount of knowledge people in different disciplines (chefs, microbiologist, food-technologist, designers) have gathered throughout the years. We then use new technologies as tools to facilitate or enhance the natural!

Edible prototypeWhat are the possible benefits and risks or negative aspects, if there are, in Edible Growth?

As mentioned above, the concept of Edible Growth shortens the supply chain enormously. It reduces Co2 emission, food waste and increases people’s awareness about the food they consume. It makes smart use of natural processes like fermentation and photosynthesis and uses the 3D-printer in a useful way instead of using it as a form machine.
