In this project we aim to select suitable valorisation pathways for side streams from Icelandic horticultural production.
The project consists of choosing optimal ways of utilization for different by-products from gardening, including that which falls from the defoliation of tomato and cucumber plants, leaves of vegetables grown outdoors such as cauliflower and broccoli, as well as leaves and stems from floriculture. In addition, the basis for improved utilization of second-class products and excess quantities of carrots and potatoes should be examined. Possibilities of extracting biomaterials and bioactive substances from selected biomass will be examined with the aim of using them as ingredients in new, more valuable products. Here we can mention fiber, antioxidants and antimicrobial substances to increase the shelf life of food and processing of flavors. It is important to consider that the consumption of side products is safe, and this will be done with a risk analysis of the raw materials as well as chemical and microbiological measurements of key products.
The results of the project will be used to:
1) Gather information on the main hazards related to the utilisation of side streams from horticulture and evaluate the limitations of their use.
2) Examine possible biological substances and bioactive substances that can be derived from this biomass.
3) Develop food ingredients and/or food products from side streams from Icelandic horticulture.
4) Prepare guidelines to improve utilization, reduce waste and add value to horticulture production.
Increased sustainability of the Icelandic horticulture sector is our guiding light as well as to create high-quality food products and ingredients, new job opportunities and catalyse innovation.
This joint project between Matís, Orkídea and the Icelandic Farmers' Association is supported by the Food Fund.
