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!

Sensor technology:
● Quality of soil / growth medium
● Precise dosing of nutrients
● Control over storage conditions

Functionality of ingredients
Alternative protein sources
But how functional are they?
Tests based on
micro/nanotechnology

Nanotechnology and food
(Bio)sensors and diagnostics
Process innovation (sensors)
Structure modification
Encapsulation (controlled release)
Packaging (depending on
recyclability)
Communication is of essence!

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?
