  • 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

    Better use of: raw materials energy water

    Micro-

    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

    Mouth

    Sarcophagus

    Stomach

    Duodenum

    Colon

    Jejunum

    Ileum Small

    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!
