Upon extraction of proteins from sugar beet leaves (Beta vulgaris L.) and oarweed (Laminaria digitata) for animal food and feed purposes, endogenous phenolics and proteins can interact with each other, which might affect the protein’s applicability. Sugar beet leaf proteins might become covalently modified by phenolics through polyphenol oxidase (P...
Manipulating and understanding matter at the nanoscale describes best the interdisciplinary field of nanotechnology. Nanotechnology is entering, a new era, which is described by Jean-Marie Lehn as the era of “complex matter”. Complex matter is the combination of nanomaterials that together give rise to superstructures, “structures beyond nanostruct...
In order to understand food product functionality such as elastic and flow behavior and mass transport properties, one first has to understand the multi-length-scale structure of the material. The aim of this work is to explore novel methodologies to study and characterize multi-length-scale structures of food hydrogels under static and dynamic condi...
Detailed knowledge of the chemical content of organisms, organs, tissues, and cells is needed to fully characterize complex biological systems. The high chemical variety of compounds present in biological systems is illustrated by the presence of a large variety of compounds, ranging from apolar lipids, semi-polar phenolic conjugates, toward polar ...
Verslag van een onderzoek naar de herstelmechanismen in de spieren van forel en karper, na uitputting in een zwemtunnel, en uitleg over de daarbij gebruikte kernspinresonantie-techniek (NMR: Nuclear Magnetic Resonance). Met deze techniek werd informatie verkregen over het verloop van de herstelprocessen in de witte spier van energierijke verbinding...
Due to their long life span, changing climatic conditions are of particular importance for trees. Climate changes will affect the water balance, which can become an important limiting factor for photosynthesis and growth. Long-distance water transport in trees is directly related to the transpiration stream and very sensitive to changes in the soil...
A new era of plant biochemistry at the systems level is emerging in which the detailed description of biochemical phenomena, at the cellular level, is important for a better understanding of physiological, developmental, and biomolecular processes in plants. This emerging field is oriented towards the characterisation of small molecules (metabolite...
Infochemicals play an important role in interactions between living organisms in aquatic environments. Although the presence of these chemical cues is confirmed in more and more systems, the chemical structures of the compounds involved remain predominantly elusive and the identification of these compounds is essential to advance the research on ch...
In areas under intensive livestock farming and with high application rates of animal manure, inorganic and organic phosphorus (P) may be leached from soils. Since the contribution of these P compounds to P leaching may differ, it is important to determine the speciation of P in these soils. We determined the effect of various fertilization regimes ...
Hydrolysates obtained by hydrothermal treatment of four xylan rich by-products (wheat bran, brewery's spent grain, corn cobs and Eucalyptus wood) were characterised. Depending on the feedstock material studied, the xylan originally present differed in substitution with arabinose, 4- O -methylglucuronic acid and O -acetyl substituents. Due to a part...
