Description

Main research question/goal
Which health-promoting fibres, vitamins, antioxidants and minerals are technically and economically viable to recover from by-products and residues from the Flemish fruit and vegetable industry? That is the central research question in this project. The efficient use of raw materials and the optimization of production (less waste, more durability) is the basis of the international competitiveness of the Flemish industry. The processing of raw materials results in commercially viable end products, but also generates by-products ??and residues that often only are valorized to a limited extent. The intention is to perform research that could result in better, high-value valorization routes for these vegetable and fruit by-products and wastes.


 

Research approach
The project identifies and characterizes the by-products and wastes of major fruits and vegetables in terms of fibre, vitamins, antioxidants and minerals. Through literature review, we list the health-promoting properties of the components present. With a bio-assay we measure the effects of consumption of these by-products and wastes on the performance of farm animals. Then we examine the extraction of the pectin fraction from fruit and vegetable streams in detail. We develop this extraction to become a sustainable and economically viable process. After optimization of the gentle extraction, we upscale via modelling and perform an economic analysis on the industrial scale as well as a market study.

Relevance/Valorisation
The developed pectin-derived product can form the basis of a health promoting fibre and gluten-free food ingredient, with or without an organic label. The food producing and processing industry has the opportunity to make use of sustainable raw materials for use in processed foods. The new extraction process also has potential to be exploited.
