to Human Health
An approach to Food Quality
Alleanze per Nutrire il Planeta

Food Quality is linked
to different perspectives ….

• sensory properties
Food Quality Aspects

• nutrients, vitamins,
minerals, secondary
plant compounds

Importance to
Human Health of
Soil Vitality, with
Special Reference to
Post-war Planning
Soil Association, 2006

• The primary factor in health is nutrition
• Fresh unprocessed food have a greater
nutritive value
• Fresh foods are more health promoting than
preserved foods
• The nutritive value of food is vitally affected
by the way in which it is grown
• An essential link in the nutrition cycle is
provided by the activity of soil fungi ...

“the concept that the nutrient cycle is not
merely a transfer of nutrient materials
from one form of life to another but also
a circuit of energy, though even now not
universialy accepted, is no longer
considered revolutionary.....”

• Wave-Particle Duality: Light
Light behaves as a wave, or as particles, depending on
what we do with it (experiments), and what we try to
observe. (Heisenberg uncertainty principle)
Our Hypotheses:
The Duality of Food
Chemical composition and self-organisation properties

1988 : Food Quality – holistic
methods and concepts
Aim:
• scientists with different background
define their approach to food
quality
• based on the definition the
appropriate method(s) were
chosen
• took part in a joint research project
with the same products

Result:
Building a interdisciplinary research group focus on
picture developing methods
Aim:
Standardization of picture developing methods
• lab documentation
• scanning and computer - analysis
• sensory evaluation on picture analysis

Standardization of picture developing methods
• lab documentation
• scanning and computer - analysis
• sensory evaluation on picture analysis

Evaluation of different regions
ROI
With different
computer programs
Texture Analysis
Structure Analysis

Validation of the methods on differentiation
• plant and animal products (age, variety)
• organic vs. conventional products
• food processing techniques

• Crystallisation process embedded in
evaporation process
• Entropy flow of the evaporation
• Rayleigh – Benard structures can appear
(self organization system)
• A dentric growth deeply researched in
physics
• Viscosity and molecular weight

Open question:
If food includes
„self-organization“
what does it mean for
human health ?
For food industry?
