Industrial application of plant proteins as binders and co-binders in paper and paints

Objectives

To produce Plant Protein Binders (PPB) with functional and technical properties tailored to meet industrial requirements in the paper and paint industry and to evaluate the combined economic and technical feasibility in producing PPB.

Technical Approach

Application tests in the paper and marked assessment to the paint industry: The proposal involves application tests of PPB in the paper industry and assessment in the paint industry. Issues of PPB functionality are:

• high pigment binding strength; control of water and oxygen retention
• control of viscosity
• control of immobilisation of the coating pigment
• good compatibility with other coating components
• high solubility in water
• low foaming capacity

High printability of the coated paper and sufficient optical and mechanical properties will be evaluated.

Optimisation of production line and production of proteins from lupins: The project involves production capability of PPB and process optimisation where issues of precipitation, ultrafiltration, full recovery of chemical modifying agents, influence of lipophilic minor components and enzyme technology will be evaluated, focused on minimising any environmental impact.

Evaluation of by-products of PPB-processing in feed applications: The proposal involves issues of marketability of residual products assessed in the feed industry including:

• analysis of semi-technical scale products for alkaloids, hydrolase inhibitors, saponins and lectins
• investigations on proteins, oligosaccharides and dietary fibres in the by-product fractions
• value of the by-product fractions as feed for monogastric animals by in vitro determination of enzyme digestible organic matter, and the occurrence of anti-nutritional compounds in the by-product fractions

Tailored end-product formulation and modification of protein for paper and paint: The proposal involves the issues of commercial formulation technology and chemical modification technology of proteins, which gives an unique opportunity for tailoring applicable end-products for the participating paper industry and in the paint industry.

Economic feasibility of producing PPB for paper and paint: The proposal involves an economic feasibility evaluation of the combined project including evaluation of optimal production for full-scale implementation.

Results to Date

The first set of pilot trials has been carried out. A standard pilot-scale production line has been set-up including seed cleaning, dehulling, aqueous extraction, purification of proteins and co-products, mill and spray drying. Evaluation of the proteins and co-products is ongoing as well as the industrial application tests in paper coating and paint formulations.
