1. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes
Sammanfattning : Renewable and biodegradable alternatives to fossil-based materials are essential as concerns over depleting finite resources and the pollution of our ecosystems are growing. Abundant, highly anisotropic, and mechanically strong cellulose nanofibrils (CNF) are attractive building blocks for the fabrication of high-performance biobased materials that can compete with their conventional fossil-based counterparts.

2. In Vitro Availability of Iron in High-Tannin Sorghum. Effect of Enzymatic Oxidation of Phenolic Compounds
Sammanfattning : Iron deficiency anemia is the most common nutritional disorder in the world. In low income countries, it is to a large extent caused by low bioavailability of iron in the vegetable diet. Vegetable diets contain large amounts of compounds that inhibit iron absorption, e.g. LÄS MER
3. Food choice in fallow deer – experimental studies of selectivity
Sammanfattning : In this thesis, I experimentally investigate feeding selectivity in fallow deer (Dama dama), with respect to plant secondary compounds, especially tannins, which can decrease the quality of foods. I found that fallow deer avoided foods with higher amounts of tannic acid and Quebracho tannin, even though the deer ate some high-tannin food. LÄS MER
4. Sainfoin tannins and their impact on protein degradation during silage and rumen fermentation and testing of novel techniques
Sammanfattning : The legume species sainfoin (Onobrychis viciifolia) has been shown to contain tannins of particularly beneficial composition for ruminant nutrition. This thesis describes effects of condensed tannins on protein degradation in general and in sainfoin specifically. LÄS MER
5. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment
Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER
