In this study valorization of cocoa bean husk (Theobroma cacao L.), common poppy (Papaver somniferum L.) and industrial hemp (Cannabis sativa L.) as frequent waste and under-utilised raw materials was proposed by a recovery process of their macrostructural and bioactive compounds and their utilization in the formulation of alginate-based hydrogel particulate delivery systems. Compositional analysis of the raw materials was performed and a simple routine for simultaneous recovery of both macrostructural and bioactive fractions developed by sequential, solvent extraction and alkaline extraction-isoelectric precipitation at two different extraction temperatures (20 °C and 70 °C). An innovative approach to utilization of both recovered macrostructural and bioactive isolates in combination with alginate was examined, aiming to formulate particulate delivery systems constituted from the macrostructural fractions as the carrier adjuncts and encapsulating the produced bioactive extracts of used raw materials. Macrostructural isolates obtained at higher extraction temperature (70 °C) were characterized by better functional properties, i.e. higher recovery yields (<12.53%), lower WHC, higher FAC, higher foaming capacities (<280%) and stabilities (<200%), confirming those extraction parameters as the preferred ones for obtaining macroconstituent isolates for encapsulation purposes. The encapsulation- case study revealed potential protein- polysaccharide interactions which did not affect markedly the physico-chemical properties, but improved the polyphenols retention in the formulated particulate delivery matrix.
