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
cotton wool Coreopsis grandiflora (flowers) cotton wool 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
Château de Lauris XVIII century Jardin Conservatoire des Plantes tinctoriales Lauris (Provence) « Couleur Garance » (M. Garcia) « Filière Colorants Naturels » (D. Cardon)
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
2- Exploitation of by-products from food processing
End day market (e.g. lettuce, onion …)
(30 –70% waste material)
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)
Aliments de Santé Chiffre d’affaires (estimation année 2000 ) ( Milliard de $ ) Taux croissance en % par an
Compléments nutritionnels
Aliments bio
Compléments Vit. et Minéraux 15,4
Plantes et compléments à base de plantes 5,1 4,0
Aliments fonctionnels 28,2 14,8 TOTAL : 67,5 + 14 + 24 + 6 + 5 +11 MOYENNE : +12 (E. Sloan, Health Ingredients, 2000)

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)
Salvia officinalis
(Lamiaceae)
Thymus vulgaris
(Lamiaceae)
Plant residues :
Salvia Thymus
4- Other by products (e.g. forestry …)
Clearing of undergrowth (brushing wood or gardens)
Cotinus coggygria
(Anacardiaceae)
Pistacia terebinthus
(Anacardiaceae)
