Collaborative project: Development of a process enabling focused impact on essential oil structure using the hydrolate phase from thyme (Thymus vulgaris L.) as a model base material
Project
Project code: 2219NR383
Contract period: 01.03.2020
- 28.02.2023
Budget: 44,372 Euro
Purpose of research: Experimental development
Keywords: essential oils, quality management, medical and aromatic plants, thyme, renewable ressources
Aim of the project is the development of a novel production process for essential oils fulfilling the requirements of European Pharmacopoeia (e.g. Eur. Ph.). In such context, the focus lies on complete compensation of natural deviations in essential oil composition induced by climatic conditions, soil and others. Therefore, a single and fully automated process step based on recirculation of the aqueous distillate (hydrolate) phase will be applied, which avoids quality degradation caused by disproportioned high concentrations of undesired oil components. The technically ambitious process control affects mainly the hydrolate characteristics and thus leads to the desired essential oil consistence. In that correlation temperature dependent differences of single substance solubilities in the condensed water vapor phase serve as base parameter for process control and hence oil quality. Currently, the overall energy balance of essential oil production indicates water vapor distillation and recycling of distillates as energy-intensive process steps and consequently as an economic challenge in Germany. Accordingly, another important aspect of the project is the development and implementation of a renewable energy concept in Groß Schierstedt, which is based on reutilization of plant residues and combines the advantages of economically and ecologically sound process management.
