Towards sustainable food production
Schutyser & van der Goot, 2011 Trends in Food Science & Technology
21
Plant-based food ingredient production
● Less or no water consumption
● Less energy consumption
More mild & fits in health diet
● Retaining native properties &
more fibres and micro-nutrients
● Less pure: functionality is more
important than purity!
Dry fractionation
● Milling & air classification
● Electrostatic separation
![Page 22: 2nd edition 12 April 2016 - 3D Foodprinting Conference3dfoodprintingconference.com/wp-content/uploads/2016/04/Pieter-H… · Enjoy your nourishing day @3dfoodprints Pieter Hermans](https://reader034.vdocuments.mx/reader034/viewer/2022050513/5f9d95948687fa022e043889/html5/thumbnails/22.jpg)

Pea: Enzymatic gelation
Transglutaminase-induced pea protein gels are stronger than heat-induced protein gels
Starch and fibre in the fine fraction absorb water, which increases the protein content and the gel strength.

What is food security?The four pillars of food security.
Availability
Access
Utilization
Stability
Sufficient quantities of food available on a consistent basis.
Sufficient resources to obtain appropriatefood for a nutritious diet.
Appropriate use based on knowledge ofbasic nutrition , food safety and adequatewater/sanitation.
The infrastructure and supply chains are notsubject to undesired or unplanned disruption.
How?“Food security exists all people at all times have physical, social and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active, healthy life.”
When?70% increase in global food production required by 2050.
– FAO 2015
