2. 1. Physicochemical properties of root fiber suspensions. A comparison between parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius)

   Author : Alejandra Castro; Avdelningen för livsmedel och läkemedel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; parsnip; yacon; plant suspensions; particle size distribution; rheology; fructans; dietary fiber;

   Abstract : The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in these two roots, and possibly encourage their further industrial use.

4. 2. Microstructure and rheological properties of plant particle suspensions prepared using different physical treatments

   Author : Patricia Lopez-Sanchez; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; yield stress; rheology; elastic modulus; cell wall; tomato; broccoli; plant particle suspension; microstructure; carrot;

   Abstract : Suspensions of plant particles are very common products or by-products in many industries such as food, paper and biofuel. An improved understanding of the complex relationship between microstructure and rheology of these plant systems might help design, control and predict their structural and material properties.

5. 3. The Physicochemical and Sensory Properties of Fruit and Vegetable Fibre Suspensions - The Effect of Fibre Processing and its Addition to Low-Fat Sausages

   Author : Hanna Bengtsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; carrot; apple; potato pulp; tomato; sensory perception; low-fat sausages; texture; heat treatment; homogenisation; Dietary fibre suspensions;

   Abstract : Due to the health effects of dietary fibre, as well as its water-holding capacity (WHC), food products are commonly fortified with fibre-rich sources. However, to be able to design food products with specific textural properties that also appeal to the consumer, it is important to understand and to characterise the physicochemical and chemical properties of the fibre.

6. 4. Xylem cells cooperate in the control of lignification and cell death during plant vascular development

   Author : Sacha Escamez; Hannele Tuominen; Andrew Groover; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Xylem; Arabidopsis; programmed cell death; tracheary element; xylem vessel; autophagy; metacaspase; lignin; secondary cell wall; chromatin; gene expression;

   Abstract : The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue.

7. 5. Conservation Laws, Numerical Schemes and Control Strategies for Sedimentation and Wastewater Treatment

   Author : Sebastian Farås; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation law; Temple class system; numerical scheme; continuous sedimentation;

   Abstract : A consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. READ MORE
