Extraction process of terpene compounds
Domaine Santé et Bien-être
Technologie Procédés relatifs à la chimie verte
Terpene compounds, the odoriferous constituents of plants, are used for pharmaceutic, cosmetic and perfumery applications.
The new process of terpene compounds extraction uses a green and GRAS solvent, the Ethyl lactate, and allows to retrieve compounds of interest by precipitation, rather than by distillation.
Challenges of current methods
- They require the use of solvents such as hexane or dichloromethane that are toxic for health, non-renewable and incur significant reprocessing costs since they are classified as pollutants.
- They need a distillation involving long time heating to remove the extraction solvent, which can be detrimental to the compounds of interest.
Ethyl Lactate is :
- Safe: no toxicity during extraction process vs hexane or dichloromethane, not carcinogenic, safe for the skin
- Green: 100% biodegradable and renewable, not pollutant
- Organic : can be used as food additive, is compatible with organic labeled products
- A good penetrant into vegetal cells : maximizes the extraction of compounds
The extraction process with Ethyl Lactate :
- Offers good yield with good specificity : extraction of terpene compounds on a large scale while keeping an extract enriched in compounds of interest
- Preserves compounds of interest
- Is more economic: less reprocessing costs, less processing time
- Can be used to extract compounds from both fresh and dry material
