SEEDFOOD: Functional and palatable plant seed storage proteins for sustainable foods

Our vision is to accelerate the transition from animal- to plant-based food proteins for sustainable food production and consumption in a world with a fast increasing population.

Rapeseed is farmed on large scale in Europe. Today rapeseed cakes containing the proteins are used for animal feed.

If the global production of rapeseed cakes is transformed to valuable protein isolates and used as food ingredients it can cover the protein requirements for 700 million human beings.

The project will:

  • establish new processes to remove antinutrients and improve the palatability (neutral flavour) of rapeseed protein

  • create food-grade protein modifications leading to the desired functionality and palatability

  • give molecular insight of interactions among plant proteins and other molecules in food matrices which will be used for tailoring the required functionality

Most of the rapeseed grown in Europe is used for industrial oil production and animal feed. The SEEDFOOD project aims to change this by creating new fundamental knowledge, so the proteins instead can be applied in new food types for human consumption.

The transition from animal- to plant-based food proteins needs to be accelerated in order to support sustainable food production and consumption in a world where the population continues to increase fast. Crude plant protein concentrates are challenged by high levels of antinutrients, poor palatability (bitterness and astringency), inadequate functionalities for complex food systems and hence insufficient quality for food usage.

SEEDFOOD aims to tailor plant seed protein with highly functional, palatable, and nutritional properties through novel protein design and in-depth understanding of molecular interactions in the food matrix. Protein functionality and protein modification are in focus along with novel processing technology, biophysics and machine learning.

The research activities are divided into four separate, but closely interconnected, themes.

The vision and approach of SEEDFOOD is described in the figures below.

Our aim in Theme 1 is to generate native napin and cruciferin isolates with reduced levels of unpalatable and antinutritional compounds and control of mineral content. This will be achieved using emerging gentle technologies and knowledge of molecular properties. We intend to avoid industrial processes that require the use of high levels of water and energy and damage the rapeseed proteins. The technologies considered for isolation, purification and non-thermal enzyme inactivation are membrane filtration, pulsed electric field and electrodialysis.

Theme leader: Professor Lilia Ahrné, UCPH FOOD

 

 

The aim of Theme 2 is to understand how specific modifications induced by food-acceptable approaches affect rapeseed protein structures, and physical properties like solubility, unfolding, surface charge, and isoelectric points in order to improve functionality and palatability. Modifications on rapeseed proteins will be induced by enzymes and UV-light. The resulting protein material will be comprehensively characterized on the molecular level and effects on protein functionality and palatability will be evaluated in collaboration with Theme 4. Recombinant rape protein mutants produced in Theme 3 will be used for mechanistic studies.

Theme leader: Professor Marianne Nissen Lund, UCPH FOOD

 

 

In Theme 3 we will use purified rapeseed proteins (napin and cruciferin) as well as  recombinant rapeseed protein isoforms and mutants for mechanistic studies on protein biophysical properties with the aim to understand structure, stability, solubility and molecular interactions. The material will be comprehensively biophysically characterized. We moreover aim to investigate the interaction between rapeseed proteins and biomolecules from saliva and food matrices, which will enable us to design protein functionalities and improved palatability relevant for application in food.

Theme leader: Professor Alexander K. Büll, DTU Bioengineering

 

 

The aim in Theme 4 is to develop functional protein building blocks (aggregates, microgels, microcapsules) using insights on rapeseed protein modifications and interactions. We will also focus on understanding how native and modified rapeseed protein isolates create desired food structures (gels, emulsions, protein-rich solutions with high colloidal stability), and improve palatability by understanding how native and modified rapeseed proteins contribute to bitterness and astringency in the mouth through interaction with saliva.
