2. 16. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

   Author : Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

   Abstract : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

4. 17. Soil salinity as a driver of microbial community structure and functioning

   Author : Kristin Rath; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

   Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

5. 18. Physico-Chemical Properties of Plant Polysaccharides Investigated with NMR Techniques

   Author : Åsa Östlund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR diffusometry; Dissolution of cellulose; Chemical shift imaging; Fiber hornification; Xylan; Molecular weight; Pore size distribution; Cryoporometry; Cellulose solution; 19F NMR; Gelation of cellulose; Self-diffusion; Pulsed field gradient NMR; TBAF DMSO; 1H NMR;

   Abstract : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. READ MORE

6. 19. Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

   Author : Cecilia Curi; Avdelningen för livsmedel och läkemedel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bixin; annatto; natural colorants; light stability in solid multiphase systems; shelf life extension; auqeous physical stability; encapsualtion efficiancy; spray drying; natural colored candies;

   Abstract : The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. READ MORE

7. 20. Reversible electroporation of Thai basil leaves as a pretreatment prior to drying

   Author : Grant Thamkaew; Avdelningen för livsmedel och läkemedel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stomata opening; trichome structure; stress response; viability preservation;

   Abstract : As commercial dried herbs are of lower quality than fresh herbs, it is of key importance to understand the effect of pre-drying treatments and drying techniques on the quality of the dried product. Several technologies are reviewed, focusing on their effects on aroma and color, with the goal of providing an overview of various technological strategies developed for improving the quality of aromatic herbs for industrial drying.
