1. Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution
Abstract : The phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. READ MORE

2. Rheology and Microstructure of Mixed Biopolymer Gels
Abstract : The viscoelastic behaviour of biopolymer mixtures showing synergism was investigated under different physicochemical conditions using small deformation oscillatory measurements. In addition, the rheological properties of binary polysaccharide mixtures were related to the microstructure as observed using transmission electron microscopy. READ MORE

3. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties
Abstract : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. READ MORE

4. Shaping of Food Microstructures
Abstract : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.

5. Role of calcitonin gene-related peptide in nociception : interactions with substance P and opioids
Abstract : This thesis presents a study of calcitonin gene-related peptide (CGRP) and its antagonist CGRP8-37 and the interactions with substance P and opioids on the transmission of presumed nociceptive information at the spinal cord level in the rat. Significant bilateral increases in hindpaw withdrawal latency (HWL) to heat and mechanical stimulation were induced dose-dependently by intrathecal administration of 5 or 10 but no 1 nmol of CGRP8-37.
