What can we expect from nanotechnology?
Better production of food
Better use of raw materials
Facilitation alternative raw materials
Less energy/water
Longer shelf-life food products
Relation between food composition and health
From farm to fork and more!
The farm / production of food
Get more out of less!
LandbouwMechanisatie, maart 2014
Sensor technology:
● Quality of soil / growth medium
● Precise dosing of nutrients
● Control over storage conditions
Food as we know it currently
What we don’t realise
Membrane separation / filtration

Particle diameter (micron)
Functionality of ingredients
Alternative protein sources
But how functional are they?
Tests based on
micro/nanotechnology
Stability of oil droplets / emulsions
Combination of micro- and nanotechnology
Krebs et al (2012) Lab on a Chip, 12(6), 1060-1070
Screening and analysis at very short time scales (sub miliseconds)!
Sensor technology: energy, water, functionality, tracking en tracing
Production of food
Nanotechnology and food
(Bio)sensors and diagnostics
Process innovation (sensors)
Structure modification
Encapsulation (controlled release)
Packaging (depending on
recyclability)
Communication is of essence!
But there is more: induce satiety in humans

Sarcophagus
Stomach
Duodenum
Colon

intestine
Digestion of oil droplets
Marze, Algaba, Marquis (2014). Food and
Function, 5(7), 1481–1488.
The interface is not
strong enough to resist
stomach conditions!
New approach: Encapsulate oil in gel beads

Corstens et al, Journal of Functional
Foods (2017) 34, 319-328.
Created distance between oil and
digestive components using nanoscale
Tested:
in the lab
extensive digestive models
in humans
Humans ate significantly less!
But it started at micro- and nanoscale!
Development of organs on chip is rapid
From technical to digestive
functionality
Design of products targeted at
personal health
To even physiological effects?
Sosa-Hernández et al. (2018). Organs-on-a-
chip module: A review. Micromachines, 9(10).
Would help consumers to eat
themselves healthy!
Nanotechnology
and food: a new
perspective on a
sustainable world!
Thank you for your attention!
