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)

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)
