Project abstract

The development of the next generation of renewable protein of high quality and functionality is increasingly important due to steadily human population growth and increasing concern about the sustainable use of traditional meat sources and protein crops.

Side-streams from the oil industry like pumpkin and sunflower leaves appear to be highly promising source of plant proteins because of high content of protein and large availability.

However, due to unique physico-chemical properties of leaf proteins, their production (isolation, purification & formulation) represents significant challenges. MultiPromis will develop an innovative concept based on hydrolytic enzymes for the obtaining both soluble protein (mainly RuBisCO) and membrane (green) protein fractions from plant leaves as well as processes for their upgrading to high-added value, food grade proteins/peptides and carrier for nutrients encapsulation.

This new concept, besides possessing known advantages of enzyme technologies, should enable innovation in bioactive peptide production from RuBisCO and in self-assembly and hybrid delivery systems for advanced nutrients encapsulation. In addition, perceive of relationship between enzyme specificity and composition of the obtained protein as well as between protein/peptide structure and function will allow new perspectives in development of novel fractions of bioactive peptides and protein nanocarriers with tailored properties and extended application.

The project is expected to achieve considerable progress beyond the state of the art and to deliver a range of exploitable results including high-value bakery products supplemented with new generation of protein ingredients and novel technologies for their production. By realizing the huge potential of oil crops leaves through the creation of a new value added chain from oil crops producers to functional food industry end-user, MultiPromis could provide multiple scientific, economical, and environmental benefits.

Problems

European food producers and consumers have an urgent demand for safe, healthy and tasty substitutes for animal-derived proteins, produced in a sustainable way. The trend of using soy protein began to decline. Agriculture uses large amounts of water, fertilizers and land. Pumpkin/sunflower leaves, harvest by-products, which can be found in high amounts in oil industries, are novel sources of protein creating a great potential for sustainable production of protein with extended functional properties for specific use.

Technological challenges

Leaves are difficult to utilize as protein sources due to high content of non-digestible fiber fractions and antinutritional factors (phytates, tannins, pigments) and protein low yields. Current protein extraction processes from leaves focus primarily on mechanical disintegration, green juice separation and thermal precipitation of protein from green juice, leaving the protein insoluble fraction in side streams. The use of enzymes represents an important strategy to enhance protein recovery from green biomass like pumpkin leaves and improve their functional properties. The enzymatic engineering concept includes search for novel enzymes, and their use in both improved enzyme-aided extraction process and enzyme hydrolysis of recovered proteins to modify their structures for novel applications (novel protein based delivery system or bioactive peptides as high quality food ingredients).

Why pumpkin leaves?

Thanks to the high content of protein, pumpkin leaves are perfect options and has played an important role in human nutrition in the past. Pumpkin leaves are an ideal source of some of the essential amino acids used to complement cereal proteins. Apart from nutrition role, pumpkin leaves appear also to have good functional properties, which are essential for achieving a high quality of food products.

Project Ambition

Green biomass conversion and biorefinery concept are mainly focus on upgrade of the lignocellulosic components of the biomass, leaving the protein fraction in side streams. Despite an enormous potential of leaf proteins, they remain underutilized as a protein in food formulations. The MultiPromis will develop biotechnological innovation in protein leaf processing, improve biorefinery technology for leave biomass and validate specialty functional ingredients for unique food application. This is in line with a European circular economy.

What is RuBisCO?

the most abundant protein in the world with subunits

RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase, EC 4.1.1.39, soluble leaf protein) is the most abundant enzyme of chloroplast, responsible for CO2 fixation in the first step of the Calvin cycle. It is a large multimeric protein consisting of eight large subunits (L) and eight small (S) subunits, also designated as the L8S8 structure (Figure 6). Although it is the largest environment on our planet covering 71% of the earth’s surface, it largely underutilized, even after detailed reviews stressed its high nutritional quality, functional properties and prospective food applications.

Project Impacts

The Project is expected to have significant progress beyond the state of the art and a range of exploitable results including at least four prototypes of innovative bakery products fortified with bioactive functional peptides and leaf protein-based nanocarrier system with encapsulated nutrients and novel enzyme and encapsulation technologies for their productions.

As functional proteins and bioactive ingredients have a typically high value, their recovering and commercializing provide a considerable economic benefit for the whole value chain from agriculture holdings, oil producer to functional food industry end-user.

Statement of the project manager

„I really believe that leaf protein and RuBisCO, particularly green waste biomass from the oil crops processing industry, have a future. At present the various forms of green biomass are primarily utilized for fibre isolation and biofuel production, rather than their proteins recovery. RuBisCO could be the main product, with high added value in the biorafinery process, when “cracking” leaves into protein, fibre, vitamins, pigments, polyphenols, and other products. We are working to make this transition towards a circular economy as concrete as possible.“
