Collaborative project: Detection and removal of pyrrolizidine alkaloid containing crop plants after harvesting, subproject 2: Development of a pneumatic driven selection of PA weeds out of medicinal and aromatic plants (PA-NIRSort)
Project
Project code: 22008418
Contract period: 01.03.2019
- 28.02.2022
Budget: 154,100 Euro
Purpose of research: Experimental development
Keywords: biodiversity, medical and aromatic plants, renewable ressources
Targeted objective: Development of an efficient sorting solution for the separation of PA weeds out of fresh and dried plant fractions of tea. At the end of the project a sorting solution shall be presented, that demonstrates the separation of pure tea plants and contaminants on elected samples. In the light of today's knowledge, a hyperspectral NIR line scan camera will do the data acquisition within an optical sorting system. Separation of different product classes shall be done by compressed air. Work planning: Goal of the work is to reduce the share of weeds within the harvested elected medicinal and aromatic plants. Therefore fresh and dried plant fractions will be recorded by a hyperspectral line scan camera. Basing on different analytical methods, features of PA containing crops will be extracted. Result is a model description for registration and separation of PA crops. Finalizing work is the transfer of models to a demonstrator for a functionality check in practice. Exploitation of results: The project shall support reducing contamination of medicinal and aromatic plants with PA weeds before placing them into the market. The use of this scientific knowledge will bring producers of these products into the position to fulfill increasing legal requirements by using of optical sorting systems.
