Development of Non Food products Claude Andary Laboratoire de Botanique, Phytochimie et Mycologie Faculté de Pharmacie, UMR 5175 Montpellier, France
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

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)
