Development of Non Food products
1- Cultivation and extraction of dyeing plants
2- Exploitation of by-products from food processing
3- By-products from essential oil industry
4- Other by-products (e.g. forestry …)
1- Cultivation and extraction of dyeing plants
Goal : to conduct experiments and in the medium term
to propose to farm workers a new agricultural field
with high added value in the area of dye plants
that include sustainable regional development.
1- Cultivation and extraction of dyeing plants
Work steps :
Screening on 43 dye plants with :
phytochemical characterisation of extracts
dyeing on cellulosic fiber (cotton) and
proteinous fiber (wool) *
colorimetric characterisation :
C* (chroma), L* (lightness) and h* (hue)
fastness evaluation (light, water)
Selection of 10 dye plants with good colorimetric
parameters and relative good light stability
Coreopsis grandiflora (flowers)
cottonwool
Achillea millefolium (head flowers)
cottonwool

Alnus glutinosa
Rhus typhina Coreopsis tinctoria
Tagetes patula
Sorghum bicolor
Solidago canadensis
Serratula tinctoria Gallium mollugo
1- Cultivation and extraction of dyeing plants
Perspectives and applied research
Improving extraction, dyeing and mordanting techniques
More phytochemical studies :
to evaluate concentration of dye compounds during
vegetative cycle of the plant
Toxicological studies :
cellular proliferation activity of dye plant extracts

2- Exploitation of by-products
from food processing
By-product problems :
costs drying, storage, shipment, …
limiting factors economically
But also a promising source of molecules, expected
to be health promoting :
dietary supplements, functional ingredients
End-day market (e.g. lettuce, onion …)
(30 –70% waste material)
2- Exploitation of by-products
from food processing
Lettuce and Onion := Functional food
(new extract with 30 – 50% polyphenols)
Antioxidant activity
Protection against UV-A and UV-B
Anti-inflammatory
Other biological activities (undergoing)

3- By-products from essential oil industry
Distillation wastes
Aqueous extracts :
selected by-products (low molecular components)
e.g. Melissa extract = rosmarinic acid
(antifungal, antibacterial)
Plant residues :
Thymus vulgaris(Lamiaceae)
Salvia officinalis(Lamiaceae)
Salvia Thymus
4- Other by-products (e.g. forestry …)
Cotinus coggygria(Anacardiaceae)
Pistacia terebinthus(Anacardiaceae)
Clearing of undergrowth
(brushing wood or gardens)
