Project Title:

Technologies for the enrichment & recovery of novel bioactive ingredients from plant food processing wastes

Project Coordinator:

Dr Dilip Rai

Project Abstract

Several plant food processors produce high levels of by-products (waste) in Europe and globally. Disposal of this waste incurs considerable costs to processors and represents a significant environmental hazard. Added to this, processors are now legally required to put in place systems to reduce waste. However there is a growing awareness that this material could represent a valuable resource if correctly treated. In fact the commercial value of plant food processing waste has been demonstrated in recently FIRM funded projects: glycoalkaloids in potato-peels (Ref No. 08/R&D/TAFRC/673), -glucans in barley (Ref. No. 06/R&D/C462) and waste/by-products of fruit and vegetable processing (Ref No. 06RDTAFRC518). These projects served to highlight that some plant food processors produce high volumes of uniform waste that contains substances with market value in the food-ingredient and pharmaceutical sectors. To date however industry friendly, low energy sustainable techniques for recovery of these components are not available. The proposed project will seek to develop optimal methods for recovery of these compounds in enriched or purified forms with a view to providing recommendations to processors for maximizing the unrealized value of this waste raw material. A multidisciplinary team will explore the use of conventional (UCD/Teagasc), novel (UCD) and biological (DIT) extraction techniques to recover (1) glycoalkaloids from potato waste- glucans from brewer’s spent grains and (3) Chitins from mushroom stalks. Combinations of these methods will also be explored and detailed characterization of the recovered compounds will be performed at Teagasc Ashtown. Due consideration will be given to the safety of the extracted material and the impact of novel extraction methods on the integrity of the compounds extracted.
