There is a global need, from sustainability, food security and also health perspective, to increase dietary intake of plant protein. Side-streams from wheat and rice processing offer large under-exploited raw material potential, and we will work throughout the agro-industrial value chain to valorise that. The main aim of PROMINENT is to develop techno-economically and environmentally viable protein-based ingredients and foods from cereal processing side streams. We will concentrate on novel fractionation and extraction technologies, such as bioprocessing, supercritical carbon dioxide (SC-CO2) -extraction, thermo-mechanical technologies, wet and dry fractionation, and expanded bed adsorption as well as their combinations as novel hybrid processing technologies. A strong focus will be in using enzymatic and thermo-mechanical methods to improve techno-functional and sensory properties of protein ingredients to reach desirable taste and texture in food applications. Pasta, biscuit, cake and beverage food models are the main end product categories, where new protein ingredients will be used as dietary protein source and act as performance proteins to deliver similar techno-functional and sensory properties to animal proteins. We will also assess the safety, quality, techno-economical feasibility, sustainability and market potential of the new protein ingredients and foods, and design strategies for marketing, dissemination, and exploitation of innovations. The project will support the economic growth, resource efficiency and sustainability of the European agro-food industry, and open new market opportunities by generating new plant protein ingredients obtained from cereal processing side streams as well as new products for the consumer food market.

Current plasma fractionation technology combines ethanol precipitation with packed bed chromatography. We have developed a novel core fractionation process comprising five expanded bed adsorption (EBA) chromatographic steps on high-density modified agarose/tungsten carbide beads. Plasma was first chromatographed on two diethyl amino-ethyl (DEAE)-tungsten carbide agarose adsorbents (respective mean particle diameters of dv(0.5)=190 and 37μm) to isolate at 50 to 80% recovery a fraction containing 4 to 7IU/ml factor II (FII), factor IX (FIX), and factor X (FX) (specific activity >1IU/mg) and another enriched in FVIII and von Willebrand factor (vWF) (∼1IU/ml and 0.6IU/mg, respectively). The flow-through was adsorbed on 4% agarose-10% tungsten carbide beads coupled with an acidic mixed-mode ligand to isolate an 80% pure immunoglobulin G (IgG) at a 93% step recovery. A highly purified α1-antitrypsin was isolated at 95% step recovery by adsorbing the flow-through on 4% epoxy-crosslinked agarose-10% tungsten carbide adsorbent material coupled with a cationic ligand. Isolation of 98% pure albumin was achieved at a 99% step recovery by pH 4.5 adsorption of the flow-through on 6% agarose-10% tungsten carbide beads coupled with an acidic mixed-mode ligand. EBA may represent a feasible alternative core plasma fractionation tool. © 2009 Elsevier Inc.
