Tailoring of secondary metabolism in horticultural residuals and cascade utilization for a resource efficient production of valuable bioactive compounds

Acronym: TaReCa

Timespan: 11.2017 – 10.2020

The project TaReCa aims at the development of tailored cascade utilization of plant residuals from bell pepper production (Fig. 1), to exploit add-on value by combining the production of vegetables with subsequent extraction of valuable plant secondary metabolites (SM) by stresses applied in production greenhouses. The project will focus on the flavonoid cynaroside, which is of interest for the cosmetic, food and pharmaceutical industries due to its antioxidant, antimicrobial and cancer-preventive properties. Leaves and stems from stress-treated bell pepper plants will be screened for additional induced metabolites, followed by analysis of market potential and entry options/barriers as well as investigations on extractability. This generates the potential for the production of bioactive compounds for multiple market segments. The project drives the development of environmentally-friendly, economic extraction and purification processes which will be coupled to a potential utilization of the remaining plant material in a biorefinery to further increase the value chain. The double or even triple utilization of horticultural production chains for food and tailored compounds will generate novel, affordable and economically relevant products for industrial applications.

In this framework, the TIM Chair group (Research Area 2) contributes to the TaReCa project within the WP6 by tackling the following research goal (Fig. 2):

Evaluation of market potentials of induced SM in bell pepper together with industrial advisory board

  • Identification of potential industrial applications of the stress induced SM from bell pepper residuals (from WP3) as well as their market potential (analysis of literature, patent lifecycles and regulatory issues) which affect their use as ingredients and further identification of the most economically valuable compounds
  • For chosen SM, detailed value chain analysis examines the feasibility of the whole cascade process (expert interviews, focus groups) through the identification of necessary resources and competencies, changes in logistics and management
  • Evaluation of the acceptance along the value chain in terms of novel processes, technologies and new ingredients coming from waste streams
