Since the start of the project, TEAGASC has investigated novel green and environmentally friendly extraction technologies to obtain valuable components from food wastes and their fermentation by-products for their valorisation. This task, under the WP5 (Valorisation of high-value by-products), has been conducted in close collaboration with WP1.

Extractions assisted by microwave, power ultrasound, enzyme, ultra-Turrax, or high-pressure technology and their combination were employed. The much higher yield was obtained under the optimal extraction conditions than under conventional extraction conditions and qualities of the extraction products were evaluated.
