We perform applied and fundamental research concerning different aspects of plant food production, processing and consumption. This is done through collaborations with industry and other research groups.
Dietary fibre in relation to food design, processing, and consumption
To achieve in-depth understanding of the nutritional properties and physico-chemical behavior of fibre during industrial processing we determine componential composition of dietary fibre in plant food materials. We investigate structural features of β-glucan and arabinoxylan, which are two of the major components of dietary fibre. In collaboration with plant breeders we implement targeted changes of dietary fibre profile in cereals, improving their nutritional and functional properties.
Starch characteristics for food and bio-based materials
Starch is an inexpensive raw material and is therefore widely used for food and non-food applications. It constitutes a large part of the energy in the human and animal diet. It is also a perfect bio-based material in many industrial applications such as papers, plastics, detergents etc. In order to optimize starch for multiple applications, we characterize its molecular structure and nutritional value as well as physico-chemical properties.
Applications of product quality know-how in plant breeding
Modern plant breeding has access to a multitude of tools that makes it realistic to improve aspects of crop quality that has not been prioritized in traditional breeding programs. Collaborations between plant breeders and product quality experts has thus become very important. We work together with the Department of Plant Breeding and the Department of Plant Biology at SLU to e.g. explore the composition and use of a novel oil crop, a potato with slowly digested carbohydrates and cereal grain with modified dietary fibre.

Current research projects
Dietary fibre, gut-brain-axis and health behaviour (Laura Pirkola's PhD project)
Diet affects our brain via gut microbiota and gut-brain-axis, the complex communication system between the gut and the brain. Rye and oats are cereals rich in dietary fibre and polyphenols, components known to affect gut microbiota. Under this project, the effects of fibre-rich bread on gut microbiota and further on gut-brain axis are studied. In addition, health communication and behaviour over these topics are investigated. The project includes an in vitro fermentation study, a clinical trial and a communication intervention study. The project supports the innovation of healthy, personalised food solutions and communication over the health benefits of grain products. This is one of the governmentally funded LivsID industrial doctoral projects and is conducted in collaboration with Fazer.

Wheat flour composition and its impact on baking properties (Louise Selga's PhD project)
Wheat flour and baking is a widely studied field, and yet the implications of wheat flour composition is not fully understood. The baking properties of wheat flour are dependent of multiple factors, many of which have been studied individually. To get further, a more holistic approach is most likely needed. In this project, multiple biochemical and rheological flour parameters are studied using multivariate analysis to find out how they contribute to the baking properties. This knowledge is highly requested from the milling and baking industry and can potentially be implemented in wheat breeding as well. This is a LivsID industrial PhD project funded by SLU and Lantmännen.

Novel potato starch – New structure descriptors may reveal properties for new applications (Xue Zhao's PhD project)
Starch consists of the two polymers, amylose and amylopectin. The properties of starch are influenced both by the ratio of these two molecules and by the structure of amylopectin. The aim of the project is to gain detailed knowledge of amylopectin structure to understand the biosynthesis of starch as well as the relationship between structure and properties. In the prolonged view, the final goal is to genetically customize starch with specific properties. The project is funded by SLU and TC4F

New starch for novel applications (Shishant Jayarathna's PhD project)
Starch is well known for its unique properties for both food and non-food applications and, the range of starch applications can be further expanded. Within the project, different types of novel potato and barley starches generated through various plant breeding techniques will be characterized for their physical and chemical properties. The aim is to understand the influences of manipulations to the starch biosynthesis pathway to the resulting starch properties. The generated knowledge is expected to be utilized by plant breeders to develop tailor-made starches already inside the plants, eliminating or reducing the need for post-harvest modifications of starch for various applications. We perceive that the project will generate the knowledge platform regarding energy-efficient, eco-friendly, and sustainable approaches to in-planta modify the starch for particular applications. The project is funded by SLU and TC4F

Complementary porridge with high nutritional quality for children in Mozambique (Sunera Zulficar Nurmomade's PhD project)
Complementary porridge with high nutritional quality for children in Mozambique
This project is an attempt to formulate complementary porridge with high nutritional quality based on pearl millet and cow pea for children under 5 years in Mozambique. Porridge is the staple food consumed widely in Mozambique and Africa made from millets and legumes. Unfortunately, pearl millet and cow pea legume also contain several anti-nutritional compounds (ANC) which inhibit the starch hydrolysis and mineral bioavailability thus impairing the growth among the children. This is a project where we will be focusing to use traditional low-cost processing techniques like traditional fermentation and germination of the millet and legume flours for tackling ANCs and achieving better nutritional profile. Flour with better functional properties will be helpful in improving the nutritional profile of the cooked porridge and can be used as a weaning food for dealing with malnutrition problems among children. The project is funded by Swedish International Development Corporation Agency, Sida.

Sustainable organic food from heritage cereal – using history to form the future
Introducing historical heritage cereals on a larger scale may have a potential to contribute to several of the UN sustainable development goals and increase profitability of organic farming. This project will examine whether heritage cereals are more resilient to environmental variation and management than modern cereals. Further, links between consumer preferences and nutritional quality of heritage cereals will be studied. This is an interdisciplinary project involving scientists at the Swedish Biodiversity Centre, SLU, the departments of Molecular sciences, Ecology and Crop production ecology, SLU, as well as the Faculty of natural sciences, Kristianstad University. Our group is mainly responsible for chemical characterization of the grains and food items produced in the project. This include for example carbohydrates and phenolic compounds. More information is available on the the project website at Swedish Biodiversity Centre (SLU).

Field cress (Lepidium campestre) – a novel oil crop for biofuel and animal feed in northern Sweden
Investigating the genetic background for increased oil content and reduced antinutritional factors in field cress (Lepidium campestre)
Meeting the growing demand for vegetable oils for industrial applications require the development of more efficient oilseed crops. Field cress (Lepidium campestre) has been targeted for domestication because it holds high agronomic promise as a biennial/perennial oilseed crop as it has many good characteristics of a high-yielding winter-hardy crop. Unlike any other oilseed crop, field cress can be highly productive in the northern parts of temperate regions. In addition, field cress provides important ecosystem-services as it functions as a cover crop during winter and can be undersown a spring cereal. The domestication of field cress is a unique project and the possibility for commercialization is approaching.
Two of the key traits for field cress commercialization is oil content and anti-nutritional factors such as glucosinolates, which are the focus of this project. The average oil content of field cress is 15-20 %, which needs to be increased to make the crop highly productive. Reducing the concentration of glucosinolates in field cress will also allow the seed meal to be used as a high-value animal feed, which will also be addressed in this project. The project is funded by Formas, and managed by the Department of Plant Breeding, SLU.

Structural features of β-glucan favoring its higher bioactivity and nutritional value
β-Glucan is a bioactive component of dietary fibre which possesses a number of positive effects on human health. Recent studies demonstrate that a higher molecular weight of β-glucan is more advantageous for the production of healthy food. Unfortunately, β-glucan molecular weight decreases at many routine processes of food production, e.g. bread baking. In collaboration with plant breeders we identified a unique barley variety containing a more stable β-glucan. Our present aim is to unravel structural features of this β-glucan and apply this knowledge for guided breeding of barley varieties with enhanced nutritional properties.
